¶ Introduction
Welcome to Project Blueprint, the podcast where we tell the stories of legendary projects and leaders behind them. I'm Will Heel, a former Air Force officer, turned project manager at Amazon Web Services where I build data centers.
And I'm Steven Laskey, a software development engineer at Amazon Web Services, where I develop machine learning applications. Today's episode is about a project that's had enormous influence on all of our lives, and that is the plane that shrank the world. The Boeing 7 0 7 Jet Airliner.
The 7 0 7 is a story of engineering ingenuity, corporate rivalry, secret Nazi research labs, and the struggle to change a company's culture.
It's also filled with great leadership lessons from legendary Boeing President, bill Allen.
I'm really excited for this one. Steven.
People say you, you have to have a lot of passion for what you're doing and it's totally true, and the reason is because it's so hard that if you don't, any rational person would give up. We choose to go to the moon and dis decay and do the other thing, not because they are easy, but because they are hard. This is Project Blueprint, the untold stories of great accomplishments and the leaders behind them.
I don't know about you will, but I'm really excited for today's episode. We've all seen these sort of classical images of what airplanes used to be with the sort of propeller driven design, but then suddenly these classical images seem to change all at once into the modern liner that we know today. But that transition from the classical airplane to the modern jet liner seems to be a mostly untold story. And so I'm really excited to learn what ultimately thrusted us into the modern jet era.
Yeah, I'm really excited about this episode two, Steven, and I think you really hit the nail on the head there because this story is so important to the modern age and jet travel. If you live in the United States, there's a 90% chance that you've flown on a jet before. But what most of us don't realize is the story of how it all happened. And really this first jetliner, the 7 0 7 set the paradigm for jet travel as we know it today.
And what's even more exciting to me, Steven, is the cast of characters for this story is not what you would expect the company we're gonna cover. Boeing had less than 1% market share of the commercial airliner industry when they launched their first jet, the 7 0 7, and they were led by this former tax lawyer named Bill Allen. This is a great story. I'm really excited to tell, and I think everyone can find some resonance in it today.
Yeah. And as I understand it, it wasn't until after 1958 where for the first time in history, more people crossed the Atlantic by airplane than by ship, and that officially launches us into the jet age. Wow. Talk about a transformative project.
¶ Boeing Prior to the Jet Age
Yeah. I'm really excited.
We start our story right after the end of World War II and September, 1945, the president of the Boeing Airplane Company has just suddenly died of a stroke, and the 45-year-old corporate counsel, bill Allen, has been chosen by the board of directors to take his place despite having no technical background or executive experience.
In fact, Steven Bill Allen didn't even think he was qualified for the job himself, and he actually initially refused the offer, but the board saw something in Allen that he didn't even see in himself and convinced him to take the job. So Bill Allen is an interesting character. He was a former corporate tax lawyer from Montana, but in 1930 he moved to Seattle and joined at the time a small aircraft manufacturer named Boeing as the corporate council. So Bill Allen is kind of quiet and unassuming.
He's almost like boring in a way. He's balding and he dresses in these like gray flannel suits. He could almost like be your grandpa, you know, you wouldn't expect him to be a CEO who's gonna lead an important company. But he's actually under that exterior, a natural leader who excelled at pulling people together to make complex decisions.
And he actually used his non-technical background as a strength at Boeing, and he would force engineers to understand their designs so well that they could explain them to him in simple and clear language. He was also known for being a great listener. He held these meetings and every meeting he had, he would start by going around the table asking everyone for their input before he would make a decision or give his opinion on the matter.
And this is really similar to stories I've heard about Jeff Bezos, who would do the same thing and basically waits for all the inputs from his subordinates before he biases anyone with his opinion or makes a decision. But hiding under this boring facade, Alan is actually a shrewd risk taker who will repeatedly bet the company on ambiguous Gambles to transform Boeing into the world's dominant aircraft manufacturer.
Wow, that's very interesting. So VE Day was just a few months ago. VJ Day was the month before. And now Bill Allen, a lawyer, is taking over to become president of an airplane manufacturing company.
Yeah. And so he becomes president at this interesting time because World War II is coming to an end and Boeing has what everyone's calling the peace problem. Boeing had been successful during World War II building bombers for the military, but with the war ending, the military is cutting back on spending. And so actually, 1.5 billion in Boeing contracts were canceled at the end of World War ii.
One of the largest factories they had in Kansas had to be closed, and 38,000 workers had to be laid off. Alan's first challenge as the new president of this company is to build a new vision for what Boeing will be after the war. One potential solution for Alan is to pivot to producing commercial aircraft for the airliners. But Boeing's not in a great position to pivot to this market.
They have less than 1% market share of the commercial airline industry, and they have a string of failed attempts to produce a commercial airliner so far. So Alan, this new president is already faced with a serious dilemma. Should he continue the familiar formula of building these bombers for the military even though business is slowing? Or would he be better off pivoting his company in a new direction to build commercial aircraft for the growing airline industry?
But pursuing the commercial airline industry will require a serious culture change for Allen and Boeing because at this time, Boeing had a reputation for not listening to their customers. The commercial airlines thought of them as a company where the military design was the priority, and then only later would they maybe try to pass off a contrived variation of one of their military aircraft as a commercial airliner.
And this fit into Boeing's culture because they were headquartered in Seattle off in the middle of nowhere in the Pacific Northwest at the time. And this created like an insular culture that thrived on technological advances, but they were not open to outside input at all. So Allen realizes Boeing culture needs to become more customer focused if they're going to succeed in the commercial airliner market. But this may be Boeing's only hope of surviving in the post-war economy.
And this, this strikes me as even more risky given the sort of state of things. At the time, air travel was not the dominant method of transportation in the 1940s. In fact, I believe long distance travel was either done by Road railroad or by ship. Certainly transatlantic was by ship. So this is like an entirely sort of new industry at the time.
Yeah, like you mentioned, Steven, at the beginning of the 20th century, the idea of crossing the Atlantic by an airplane was pure science fiction. And so people mostly took ships or trains to travel any sort of distance. And in the early 19 hundreds, airplanes were just viewed as a novelty. But that changed a bit. In 1927 when Charles Lindbergh's successful flight across the Atlantic changed everyone's perception.
People began to realize air travel could promise a new age of improved transportation. And so by 1946, just after the war, the Douglas DC six, which at the time was the state of the art in passenger aircraft, could cross the Atlantic in about 15 hours compared to six days by ship. But even after Lindbergh's flight, transatlantic travel by plane was only for the very few airline passengers were mostly movie stars and celebrities, kinda like the type of people who fly on private jets today.
And that's because flights were really expensive. So at this time, a flight from New York to London cost about $11,000 in 2020 $5 round trip. So it was prohibitively expensive for most people to travel at all. And for this reason, like you said, most people still cross the Atlantic aboard ships. But for those who did fly, intercontinental flights were glamorous and very cheek. So this era in commercial aviation was known as the golden age of flying.
And if you've ever seen these videos or pictures where people are flying in airplanes that look like basically luxury hotels in the sky, this is that era in the late 1940s. And what's really interesting to me is the reason that it was such a luxurious experience, and that was because at the time, airlines were competing with the luxury ocean liners like the Queen Mary and these other elaborate floating hotels. So to compete with them, they offered similarly luxurious experiences.
Flights in this golden age of flying would have five course meals with literally caviar and champagne served. They would have gold plated cutlery. The airlines had cocktail lounges and sleeper berths because they weren't trying to cram as many passengers onto the flight as possible. They were just trying to sell really high priced tickets. And so passengers dressed up to fly.
They wore suits and dresses, and then the stewardesses on the flights were also dressed in these really fashionable uniforms from designers like Coco Chanel and Christian Dior.
So then I imagine the cost of flying was significantly higher than the cost to use an ocean liner.
Absolutely. But you know, you're paying for speed because like you said, it takes maybe five or six days to cross the ocean by ship. But you can take a flight in say 15 or 16 hours. So it's a good value for these customers to be able to reduce that time to just 16 hours.
But ultimately, flying was reserved for the wealthy at this time.
Yeah. So it's only available for those who can pay for it. And really, you know, people who need to pay that much to get across the Atlantic. So it's like celebrities, businessmen, people who have a need. But flying during this time period was not all luxury too. All these anonymities were offered because the flights were so long and people needed something to do on the airplane.
So this time a flight from New York to London on the state-of-the-art DC six was about 15 hours, and that included two fuel stops along the way. But a modern 7 87 jet liner can do this trip in six and a half hours nonstop. But they didn't just take longer than today. The flights could be much more uncomfortable compared to flying today. So at the time, most of the aircraft could not cruise at a high enough altitude to fly above the weather, so they'd have to fly through it.
And so you can imagine flying through thunderstorms, there's an incredible amount of turbulence. It's not like the comfortable, relatively smooth flights that we enjoy today. And then also at the time, these are all propeller driven aircraft, so they're incredibly noisy. They create a lot of vibration.
There were also higher accident rates, unsurprisingly, because the planes were more mechanically complex, flying wasn't as developed as today, and so there was a much higher risk every time you flew as well. But that's all about to change after World War II because the advances during the war in military airplane design are poised to usher in a new age of commercial, a aviation.
And there's kind of two key factors that are setting up the aviation industry to really take off after World War I. The first is jet engines. So jet engine research during the war promises faster and smoother and more reliable aircraft. Also, a lot of the former military airfields created during World War II are going to offer the necessary infrastructure for global air travel because before this time, there wasn't as much demand for airfields.
And building an airfield is a very intensivess project. There just weren't that many airfields to begin with, but a lot were built for World War II because of the war, and so they're going to provide a springboard for the commercial aviation industry to really take off.
Oh, wow. Yeah. I didn't realize that World War II essentially kickstarted the commercial airline industry.
So Bill Allen realizes that the opportunity of faster jet airliners could be aviation's next Lindbergh moment. But again, Boeing isn't necessarily well positioned to take advantage of this new jet age. So far, Boeing has been a three time loser in the commercial airliner business. So their first attempt was back in 1933 when Bill Allen had just joined the company. Boeing released the Boeing 2, 4 7.
It was their first commercial plane, and it was actually technologically ahead of its time at a time when most companies were still building biplanes out of wood. The 2, 4 7 was actually a single wing design with an all metal cabin. But critically, the 2, 4 7 was held back by an internal disagreement within Boeing on if the plane should prioritize performance, like speed and maneuverability or passenger comfort.
And so Boeing's engineers at the time made this fateful decision to sacrifice comfort and economy for better speed and performance. And this would go on to set the tone for how Boeing would design all of their commercial aircraft. But that's by no means the only way to design a commercial aircraft because just down in Santa Monica, California, another company called the Douglas Aircraft Company led by Donald Douglas releases their own commercial airliner called the DC one.
And so the DC one was actually heavily influenced by the design of the Boeing plane because at the time and even up into World War II and afterwards, Boeing was the technological leader in airplane design. So Douglas heavily based their design of the DC one on Boeing's plane. The engineers at were really friendly with the Caltech technicians who were doing all the wind tunnel testing for Boeing. And so it was suspected maybe they kind of passed their design along.
It's interesting because Donald Douglas ran his company kind of the opposite to Boeing. He wasn't as innovative and technologically ahead as Boeing, but he was great at listening to his customers. Boeing released their plane immediately into service, but Douglass continued to refine their design based on feedback from the airliners.
And they developed very close relationships with the airline executives, and they made extensive modifications to their design and ultimately created a new plane called the Douglas DC three. The DC three had twice as many seats as the Boeing, a wider passenger cabin, and was also much more comfortable to fly on. And so the results of working closely with the airlines were immediately clear, and the DC three became the dominant airline for the commercial flights.
And the DC three is an important aircraft because it basically kickstarted the commercial airline industry for the first time with the DC three airlines could make a profit without flying air mail subsidies. So within a year, the DC three had completely captured the commercial airline market and was carrying 95% of all airline passengers in the United States.
The DC three made Douglas the dominant commercial airplane manufacturer for the next 30 years, and the Boeing 2, 4, 7 basically became a forgotten airplane. There's a clear leadership lesson here to me, Steven, and that's the importance of listening to your customers. It really stands out here because despite the superior technology at Boeing, they lost out to Douglas because they refused to listen to their customers.
Yeah, and I agree with that leadership lesson. I think there was a little nuance to it, because you don't want to become like a customer zombie of sorts, where you just sort of blindly fulfill every last request that they have because then your product can't generalize. Well, which has been my experience at Amazon. I've, I've worked an organization where the entire model was to work directly with customers to build products, but you also don't want to be blindly, just go build your own thing.
Right? And so it's clear that Douglas struck a balance here, apparently, and built a very successful airplane.
Yeah, it's absolutely about striking a balance. And why this story really stands out to me is because I think engineers can sometimes be the most susceptible to the thinking that as long as we have a great product, people will want it. But that's not necessarily true. You can have the most technologically advanced design and airplane in the world, but if you don't sell it and you don't continue to modify it with your customers, you're not gonna be anywhere.
And so Douglas really struck that cord of having a great product to start out with, but also iterating it to make sure they had that product market fit with the airlines.
Yeah. And their product was solving their actual customer's needs rather than theoretical customer's needs that may or may not have been there.
Yeah,
yeah. So it's like
this push-pull
dynamic. Okay. So Douglas' philosophy was clearly to iterate quickly with customer feedback. I can clearly see how this is a huge advantage over Boeing,
but Boeing doesn't give up on a commercial airliner. They try again in 1940 with the first pressurized commercial airliner. So before this time, most aircraft were not pressurized. So that limited how high they could fly. And it also made the flights uncomfortable because it's basically like being at the top of a really tall mountain. So the first pressurized airliner is a great improvement in passenger comfort. But Boeing based it off the B 17 bomber design, it was not a purpose-built airliner.
It was kind of this mutation of their B 17 bomber design. And this design was known as the Boeing 3 0 7 strato liner, but its success was eventually overshadowed by first, a tragic test flight that killed several of Boeing's key designers, and then also the start of World War ii. The USS entry in 1941 really reduced the demand for commercial flights, and so it was the wrong plane at the wrong time.
Yeah. And then I imagine all of Boeing's attention turned to military aircraft given the need at the time.
Yeah, and Boeing became very successful during World War ii. The bombers they built were some of the most successful bombers of the war. For example, the B 17 Flying Fortress became one of the legendary airplanes of World War ii, and almost 13,000 were produced for the war effort.
In later stages of the war, Boeing also built the B 29 Super Fortress, and this was a long range strategic bomber used in the Pacific, and this was ultimately the plane that dropped the atomic bombs on Hiroshima and Nagasaki. But what's important to highlight here is the design criteria for military and commercial aircraft are very different.
And so designing these military planes reinforces Boeing's bias towards speed and performance rather than the comfort and economy that are important for commercial aircraft.
Yeah, I mean, that makes complete sense to me. If you spend all your time building successful military aircraft, that would certainly bias you in a very specific way once you go to build any other aircraft.
Yeah, they're almost like two different markets. You know, it's like right building semi trucks versus passenger cars. After the war, Boeing tried again for a third time to produce a commercial aircraft, and this time again, they adapted another bomber, the B 29 to develop a four engine airliner called the Model 3 7 7 strato Cruiser.
And so this model 3 7 7 Strato cruiser was the most powerful piston engine aircraft ever produced, but it suffered from reliability issues because of the huge engines that needed to produce this much power. And really the theme here is that piston engine technology had peaked during World War ii. And so by the late forties, the tech had been pushed way beyond its limits to the point of diminishing returns.
So only 55 strato cruisers were ever delivered because of the serious reliability issues compared to about 700 of Douglas's competing plane, the DC six. So again, Steven Boeing developed the more technologically advanced airplane, but lost out to Douglas who prioritized what mattered to customers.
Yeah. And they're still getting like a 5% market share. They're just not making any progress on Douglass yet.
Well, they're not even getting 5% because after World War ii, Boeing actually had less than 1% of the commercial airliner market. No kidding. The commercial airline market was dominated by Douglas with their DC six, and then a smaller player was Lockheed who had the constellation, another four engine piston driven airliner.
So this is the same Lockheed that eventually becomes the modern day Lockheed Martin defense contractor.
Yes. Lockheed Martin doesn't produce any commercial airliners today, but back in the day, they competed with Douglas and Boeing.
Hmm.
Bill Allen had been with Boeing since the early days, so he was intimately familiar with all of these commercial aircraft failures, and he realizes that Boeing's going to need to change their culture if they're ever going to develop a successful commercial airliner and survive without these government military contracts.
But in the closing days of World War ii, the discovery of a secret research lab hidden in the forest outside the German village of Vulcan Road would give Bill Allen the breakthrough he needed to challenge Douglas for commercial airliner supremacy. During World War ii, the Germans were actually the leaders in Jet Technology. They developed the first mass produced jet engine called the JUMO oh oh four, and they also deployed the first operational jet fighter, the ME 2 62.
And so the German LFA established a secret research complex outside the village of Vulcan Road. And these buildings were actually camouflaged as farm houses and hidden below ground and under the tree line to hide them from Allied Bombers. Because the research these scientists were doing was so critical for the war effort. And the German scientists and engineers at Vulcan Road were working on a very specific problem.
And that was how to design a plane that could fly just as fast as these new jet engines the Germans were developing. And so in the final days of the war in Europe, Boeing's chief Aerodynamicist, George Cher, was selected to join a scientific advisory group code named Lusty. The goal of this scientific advisory group was to find and collect German research before it could fall into the hands of the Soviets or be destroyed.
And this team actually discovered the Vulcan Road Research Center, and they found wind tunnel data showing how an airplane with swept back wings and jet engines could achieve these incredible speeds. Speeds approaching the speed of sound. So sharer urgently wrote a letter to Boeing engineers back in Seattle, and he explained his findings, urging them to make these changes to Boeing's next generation bomber, the XB 47.
So this is interesting to me. So what was sort of the key finding from the research?
So interestingly, it was actually the allies pulling together several different research efforts from different German labs in the last days of World War ii. The German scientists were actually isolated and they weren't able to really communicate with each other. So one research lab was developing jet engines while this lab at Vulcan Road was working on the swept wing design.
And so because they were so separated and not able to coordinate during the chaos of World War ii, they were never able to pair these two technologies together. The problem with the jet fighters was that they couldn't go fast enough, but then the swept wing design was the solution. They just hadn't put the two together.
And so Boeing's breakthrough was they got all of this data together and they were able to see that these jet engines will make incredibly faster aircraft, but they're gonna be unstable at high speeds. So the solution to that is a swept wing design.
So what was the state of the art in the United States at the time for jet engine technology?
So the United States was basically in third place on jet engine technology. The Germans were the most advanced, but actually in parallel with the German research, British engineers were also producing their own jet engine. And so they were building a prototype jet engine during World War ii, and they actually sent one of these prototypes to the United States for engineers in the US to research.
But the British and the Americans were never able to operationalize the jet engines during World War ii.
So the core discovery here is the amalgamation of several siloed research facilities in Germany, rather than some singular, standalone takeaway.
Yeah, yeah. And and the key pieces to remember here is it was the pairing of the jet engine with the swept wing design. Oh, very interesting. Schreyer returned to Seattle and oversaw the redesign of the XB 47 using the data from Vulcan Road. The XB 47 was this experimental jet bomber, and it first flew in December of 1947, shortly after the war. And it was the first American jet bomber and it featured these potted jet engines along with the swept wing design for high speed stability.
So this XB 47 was one of the most advanced aircraft of its day, and it would go on to define Boeing's entire design philosophy for military and commercial jets. So then building on the success of the XB 47, Boeing would go on to introduce the first long range jet bomber, the B 52. And this has been incredibly successful as a bomber for the Air Force and B 50 twos are actually still in operation today.
Yeah. I believe that the US Air Force still has B 50 twos that are like 70 years old or something. It's crazy,
I think. I think they may be one of the longest serving airframes in the US military.
Yeah.
So again, Boeing is doing really well with these military bombers. The XB 47 and the B 52 make Allen wonder if this new jet age will give Boeing the chance for the commercial airliner success that has alluded them so far.
So I'm trying to frame this in my mind. It's the end of World War ii. Military contracts are being canceled presumably. What kind of situation does this put Bill Allen in?
So it's a tough decision for Bill Allen because even though there was an initial drop off after World War II in military aircraft, quickly, the Cold War ramped up. And the US Air Force had all this demand for a long range strategic bomber that could be part of America's nuclear arsenal. But Alan's still unsure because these military contracts can be canceled at any time. Right? So he has this choice.
Does he want to ride the new success of building these long range jet bombers, or does he wanna diversify Boeing's operations a little bit and try to also build a commercial jet? So Alan decides to find out for himself, and in the summer of 1950, he plans a test flight on the XB 47. And I think this is a great leadership lesson here, Steven, because it highlights the importance of getting out of the office and seeing for yourself and touching some grass.
Yeah. 'cause at the time, most people dismissed Jair aircraft as only a military technology. But also most people had never flown on a jet themselves because these were just experimental military aircraft. So Alan decides to fly along himself and see what it's actually like. And he comes to this realization that these jets are much faster, much quieter, and a lot smoother than the propeller driven aircraft that he's familiar with.
And so he realizes firsthand at this time, the tremendous opportunity of jet engines for producing a better commercial aircraft. But most of the top engineers at Boeing were reluctant to invest in a commercial jet, and they had good reasons at this time. Boeing's expertise had always been in producing these military aircraft, and so they'd done really well with the jet bombers, but they had this long list of failed Boeing commercial airliners.
But then also at the time, even outside of Boeing, jets were considered as a military technology. They were incredibly loud. They consumed a lot of fuel. They left these black trails of soot in the sky. These were very early iterations of jet engines, and they weren't nearly as well developed as they are today. And so even the leaders of most of the prominent airlines agreed that it was too early for a commercial jet to be viable.
So at this point, Boeing doesn't even have an interested customer if they decide to produce a jet airliner. So I think Clive Irving sums up Bill Allen's decision here with a really good quote from his book called Jumbo. And he says, as a company strategy, you could look at the jet decision two ways. Either in one leap you would leave the opposition looking archaic, or you would end up with a speculative airplane, one that no one had asked for.
That would involve changing every detail of operations from maintenance to airport handling, and they would have to get safety certification according to rules that did not even exist for jets. There was no real evidence that the world was ready to switch to the jet.
So we're in the late 1940s, and Boeing is mostly a military aircraft company. They had a lot of success building bombers in World War ii, but now the war is over and the future of the military aircraft business is questionable. Now, Boeing's new president, bill Allen, who has a law degree, by the way, is faced with a tough decision. Commercial airliners are not an obvious pivot, especially given the fact that Boeing failed three times in this area.
But the design secrets from Falcon Road offer a new, more ambitious kind of aircraft, one that's faster and more comfortable than any propeller aircraft at the time. So now Bill Allen is faced with a tough choice. Does he double down on military aircraft or does Bill bet the company on the new jet engine technology and challenge Douglas for control of the commercial airline market? And
so Alan's difficult decision about should he build a jet airliner or focus on the military jets is about to get a little bit easier with a surprise that comes from across the Atlantic.
¶ The -80 Prototype
So Steven, I mentioned earlier that behind the Germans, the British had the most advanced understanding of jet engines in the early 1950s. And in May, 1952, the British Aircraft company Dhaval Land, launched the D Haviland, DH 1 0 6 comet one jetliner. And this was the first jet commercial aircraft. And it was kind of a taste on how the dead engine could transform passenger air travel. The comet cruised at 500 miles an hour versus 200 miles an hour.
For the DC six, which was the state-of-the-art propeller aircraft. The comet could cruise at 35,000 feet versus 20,000 feet for the DC six. And critically, this cruising altitude allowed the comet to fly above the weather, making travel much more comfortable, much less turbulence because they're flying over not through the weather.
And the comment was also a source of national pride for the British government who had subsidized its development in this attempt to make Britain a dominant player in the global airline industry after the war. But surprisingly, the comment did not include many of the improvements Boeing had included in their XB 47 experimental jet bomber, like the swept wings or the potted jet engines.
So Alan decides to see for himself what this comment is all about, and he travels to the annual British Air Show at Farmborough to see firsthand. Alan is joined by Maynard Pinnel, a rising star at Boeing. Now, Maynard Pinnel is a 30 5-year-old structural engineer who had actually come to Boeing from Douglas, and he had designed bombers for Boeing during World War ii. But Pinnel really wanted to design a commercial jet for Boeing.
He said, I enjoyed working on commercial programs, more serving humanity rather than threatening it. And penal is very conscious of the culture differences between Douglas and Boeing. And he felt that Boeing could learn a lot from Douglas on their attention to customers. And Allen identified penal as someone who could be an ally in his quest to transform Boeing's military bomber expertise into a commercial airliner.
So after the air show, Alan asked Pin, what did you think about the Comet and Pin's answer is We could do better. And pin's answer is going to be confirmed when they visit the factory where the comet is produced in Britain. And they're surprised when they arrive because it's nothing more than a workshop and they don't really have a production line. They're only producing a few of these comet jet liners.
And really it reminds Alan of Boeing's first plant at the edge of Lake Washington in the early 1930s and with the success of the XB 47 and now the Comet Allen starts to seriously consider green lighting a commercial jet program at Boeing.
So Bill Allen flew in the XB 47 and this sort of inspired him about how much faster and smoother commercial airliners can be. And then he goes and visits this comet factory and takes away that Boeing can do much better than them. So at this point, he's leaning towards pivoting Boeing towards the commercial airliner, but he's not there yet. Will what ultimately makes the decision for him?
Yeah, so this is really interesting to me. He's maybe 90% of the way towards deciding to build a commercial jet at Boeing, but he's not quite there yet. But remember what we said at the top of the episode, bill Allen was originally a corporate tax lawyer, and so he finds this tax advantaged way to finance the design of a jet prototype.
During the Korean War, the government had instituted an excess profits tax to ensure that no companies profited too much from the wartime increase in demand for military jets and that sort of thing. So obviously Boeing did really well during the Korean War supply and military bombers, but because their profits had been so low during the post World War II slump, the increased 1951 profits faced an 82% tax.
82%, yeah. They only got to keep 18% of what they made.
Yeah. So Alan, being the savvy tax lawyer, realizes that rather than pay these high taxes on Boeing's profits, he can just reinvest that money back into the company on an audacious new project like a commercial jetliner. So ultimately, 11 million of the $16 million needed to develop a commercial jet prototype was money that would've otherwise gone to the government.
Wow. Wow. I mean, it makes perfect sense and I think it's something that only Bill Allen could have found out because of this unique background as a lawyer. But you know, it's a much easier decision when you're trying to think, should we green light this project when two thirds of the cost are going to be money would've lost otherwise.
Right. Exactly. It's, it's basically a springboard into this new program. I don't know about you will, but it really stands out to me the unexpected qualities that leaders from different backgrounds can bring. I just learned that Bill Allen is a lawyer who's now leading an airplane company and frankly, I didn't think he was up for the job.
Yeah, absolutely. I think on paper you would say, well, Boeing is this really technologically sophisticated company. You probably want an engineer running it. And I think nine outta 10 times I would agree with that statement. But again, it shows that the right person for the right job might not be obvious and there's always these nuances.
I think at the time, you know, Boeing had this really engineer heavy management structure, so just adding another engineer to that mix is just going to make Boeing more focused on these science projects than actually delivering something that they can sell.
It's almost better to have Bill Allen, who's someone non-technical who can restrain these impulses from the engineers, and so it's kind of this balance, this push and pull between investing in r and d and solving these engineering problems, but also being a profitable company that responds to customers and delivers a product that people are willing to pay for.
Yeah, he seems perhaps the perfect man to change the culture at Boeing.
So Alan makes his decision that Boeing will invest in building a commercial jet prototype, and he calls for a full commitment within the company. The next day, Boeing engineers arrive at work to find a notice plastered across the walls. Reading life is too short to work on propellers.
Oh, that's so funny.
And so the jet age has started at Boeing, Alan assigns Maynard Pinnel and an aerodynamics engineer named Jack Steiner to design and build a prototype with the designation 7 0 7. This prototype would be influenced by the technological breakthroughs of the XB 47 and the B 52, but otherwise it would be a completely new design, not a variation of a military bomber.
Okay. So a new platform, but I'm curious why the designation 7 0 7? Where'd that come from?
So the first commercial airliner Boeing built was the 2 4 7. So it was like a two series designation. Right, right. Follow ons from that had been three series, but then interesting, the four and five series were already reserved for missiles that Boeing was building for the government. Oh, no kidding. Okay. So the next number was, you know, seven through nine and seven just kind of has a, a nice ring to it, like Yeah, it does. Yeah. Lucky number seven.
And then they chose 7 0 7 because it's an iconic number. It is. Gotcha.
Yeah. Very interesting.
Just to reflect here on Alan's decision, he's made the call to bet the company and build this commercial jet aircraft prototype. But even though we talked about how the development costs were tax advantaged, it's still a risky gamble. In contrast to most planes, this is gonna be funded entirely out of pocket by Boeing. They don't have any customer lined up. They don't have a military contract in place. And so that's not typically how airplanes are developed.
You know, usually there's a military contract in place, or they've partnered with some airline who says, we promised to order at least X number of initial aircraft, but Boeing is just going out on a limb here. And really, they haven't even socialized this with any airlines yet. Alan has greenlit this project all by himself, but Alan is not completely betting everything on this.
He's also hedged his bets a little bit, and so the engineers at Boeing promised him that this prototype could also be used to inform the design for a new military jet tanker to refuel the B 52 penland Steiner kick off the design of a 7 0 7 prototype. The goal here is to be a proof of concept design. It's not intended to be mass produced or sold. It's going to be a prototype that can inform a future jet airliner or this military tanker that I just mentioned.
But before the design started, Alan made one more key change to disguise this new jet airliner strategy from Douglass and some of the other competitors. He renamed the program from the 7 0 7 to the 3 6 7 dash 80. So Steven, the reason he does this is because 3, 6, 7. Was one of the model numbers for an existing military plane that Boeing produced. And so calling it the 3 6 7 dash 80 suggested, it's nothing more than a variation on an existing design.
That's interesting. So he is disguising this from Douglas. Was Douglas considering jet technology for commercial aircraft at this time?
No. Critically they weren't. And it makes sense from Douglas perspective because they're the incumbent. They are very successful with their commercial airliners, but they're also known for creating basically the most advanced propeller driven aircraft. So they're king of propeller aircraft and they come out publicly and say, you know, it's not time for the jet engine yet. Maybe eventually there'll be jet airliners, but we're gonna keep producing our propeller driven aircraft.
So key to Alan's strategy here is that he's counter positioning Boeing against that idea. Pendulum Steiner start the design of the 3 6 7 dash 80 prototype, but it becomes known within Boeing as just the dash 80. And so for the dash 80, they're going to incorporate two key design features that were used on the XB 47. That's the swept wing design and the podded jet engines. So to start with the jet engines, the dash 80 was designed to use four Pratt and Whitney, JT three C Turbo jet engines.
And these are the same type of engines that were used on the B 52. So this is a proven turbo jet engine that Boeing knows will work.
Okay, will. So they're switching to turbo jet engines. But what are the advantages over piston engines?
So one of the key advantages is propeller driven engines have top speed constraint, and that's basically limited by how fast the propeller can spin. So at high speeds, the tips to the propellers can actually exceed the speed of sound, and this causes these compressibility effects that reduce the efficiency of the propeller.
So adding more power doesn't necessarily result in a faster propeller and more thrust, but a jet engine, on the other hand, it compresses air, combust it with fuel, and then shoots it out the back of the engine to create thrust so they're not limited by the speed of their moving parts. In the same way, the propeller and piston engine is also, jet engines are much more reliable than piston engines, and this is two main reasons. First, they're just simpler than piston engines with less parts.
And then also jet engines have a smooth and continuous combustion and rotation cycle compared to piston engines that rock back and forth in the four stroke cycle. So interestingly, when engineers at Boeing were working on one of the first jet bombers, the XB 47, 1 of the questions that came up was, how should we mount the engines? And this is really interesting to me, Stephen, because on the comment, the engines are buried inside the wing, close to the fuselage.
And this is exactly how propeller airliners were designed. So by default, that's how the Deha land engineers thought that jet engines should be mounted. It reduced drag a bit, but it was also just kind of the way it had always been done before. But for the dash 80, the Boeing engineers drew inspiration from the XB 47. And for the XP 47, the engineers went through a few iterations of where should the engines be mounted.
So their first idea was to mount the engines inside the fuselage within the structure of the airplane. But the military didn't like this for their bomber because just a few hits to the engine would destroy the entire airplane and set it on fire.
I guess the idea there being, if the engine gets hit, it would explode and the shrapnel would tear up the rest of the airplane.
Yeah. So if the engine's punctured, you know, the fan blades could go flying, you could have a fuel leak inside of the airplane. I see. So it's really critical that these engines are separated from the crew, but also the bomb load in these bombers.
Yeah.
Makes sense. So then Boeing's second idea is to mount the engines directly on the wing, just like the comet. But the engineers rejected this idea because any engine failure would endanger the entire wing. So at this point in time, jet engines were still a new technology, and the risk of failure was very real. If an engine mounted inside the wing were to catch fire, it could threaten the fuel tanks that on most aircraft are stored in the wings.
Also, if the turbine blades inside the jet engines failed, they could shoot metal fragments through the wing. And so basically if you lose an engine, you're also losing a wing, which basically means it's going to be a disaster.
Yeah, catastrophic.
So ingeniously, the engineers at Boeing have this idea to mount the engines in pods hanging on these struts below the wing. And so this is how jet airliners are all designed today. You have the engines hanging down in pods from a strut. And so with this design, if there's any engine fire or failure, the slipstream of the air will carry the flames and debris under the wing, not through it.
Yeah. And then I, I imagine this also has maintenance benefits as well. 'cause you can just easily access the engine. It's hanging right there off the wing, rather than having to like open up the wing or open up the fuselage.
Yeah, so my understanding is it's relatively simple today for airliners to swap out a whole engine on a plane. Whereas the comet, the engines were buried inside the wing, so you have to open the whole thing up to do any kind of maintenance or repairs. So Boeing engineers decide to use the same mounting configuration for the dash 80. They design it with four turbo jet potted engines slung below the wing. So Will why four?
So at this time, jet engines were much less reliable and they also produced much less thrust. So one, there's concerns that, you know, if you lose an engine in flight, you wanna have some redundancy so that you can still fly with fewer than four engines. The other concern is these early jet engines didn't produce near as much thrust as jet engines do today. And so they need more engines to be able to meet the range and payload requirements of jet aircraft.
Yeah, that makes sense. And it's also my understanding at the time, even propeller air aircraft, the standard was four engines because the reliability of piston engines was so low that even on flights across the Atlantic, it was fairly normal for an engine to fail. And I think they would keep going as long as they still had three, if I'm not mistaken. So totally different time.
Yeah, reliability was much different than it is with today's aircraft. But Steven, I think there's a really interesting leadership lesson in this too, when you compare the potted under the wing design that Boeing went with compared to the comets in wing engine design. And it's really to me, an illustration of what you could call tyranny of the reigning paradigm.
And what I mean by that is that the de haviland engineers didn't question the assumption that the engines should be attached to the plane, just like propeller engines had in the past. They were stuck in the propeller age when Boeing had moved on to the jet age. And this really highlights to me that you should always question your assumptions. And the new paradigms call for new thinking jet engines were an entirely new paradigm.
And so it's not obvious that we should just do things the way we did in the propeller age. And to me, the Boeing engineers got this right because they solved the problem from first principles, not by doing it the way it was done before. Now with these faster jet engines, there also need to be innovations in aircraft design to ensure the stability at these new super high speeds near the speed of sound, the aerodynamics of an aircraft actually start to change in unexpected ways.
And some World War II pilots had actually noticed this in some of the fastest propeller driven fighters during the war. There were several unexpected crashes at high speeds near the speed of sound due to these mysterious instabilities that would arise. And engineers have been struggling for a long time to understand the cause of this phenomena.
But the wind tunnel data from Vulcan Road offered a solution as an aircraft, approaches the speed of sound, which is about 760 miles an hour at sea level. The air molecules in front actually don't have time to move out of the way because the airplane is traveling so fast. Instead, they start to bunch up and compress like a traffic jam in the sky. This creates these shock waves or sudden jumps in air pressure and a dramatic rise in drag.
So engineers call this effect compressibility, and it was a huge barrier in early high speed flight. This meant the propeller tips, control surfaces and the entire aircraft could suddenly lose effectiveness or even break apart if they weren't designed to handle it.
Wow, that's very interesting. So what was sort of the solution to this phenomenon?
So the solution was discovered in that wind tunnel data at Vulcan Road, and it was to angle the wings back to slow the airflow over the wings and delay the onset of this compressibility. And so using this discovery, a swept wing was first implemented on the XB 47 to allow for smooth flying at high speeds. Okay, building on this research, the dash 80 was designed with a 35 degree wing sweep to counter the effects of compressibility and cruise at speeds of up to 600 miles an hour.
Interestingly, the comet had a relatively modest wing sweep of only 20 degrees, and that limited its cruise speed to only 450 miles an hour. So that 450 miles an hour is faster than the fastest propeller driven aircraft at the time, but it was significantly slower than the dash eighties, top speed of 600 miles an hour.
I'm noticing a trend here. The more you sweep the wings, the faster you can go.
Yes, but it's a really interesting trade off because if you sweep the wings back too much, you'll compromise the low speed handling of the aircraft. So the swept wing design is good for really high speeds near the speed of sound, but at low speeds, you want less sweep back so that you can have better low speed handling for takeoff and landing.
Now, the dash 80 rolled out to the public in 1954, and it was painted in this really iconic brown and yellow paint style, and it was a big festivity at the Boeing factory when it was first introduced. Actually, bill Boeing, the founder of Boeing, who had long since retired, came back to see the dash 80 because it was such a revolutionary aircraft for the time.
Yeah, wow. What a amazing moment That must have been.
Yeah, I mean the dash 80 was really this peak into the future of what most modern airliners would become. A lot of modern jets share these key design elements like the potted jet engines and the swept wing design. And interesting to me, Boeing was the leader in this high speed airplane technology because they had invested the time and r and d to think how a jet engine should be designed based on first principles.
And so because of this, Boeing engineers are able to create a design that's faster and safer than the comet.
So the 3 6 7 dash 80 gets rolled out to the public in 1954. But just to be clear, it's still not called the 7 0 7 yet, at least officially,
no. This dash 80 is just a prototype. It was never meant to be sold as a commercial airliner. And Bill Allen had kind of hedged his bets. It was a prototype jet transport, you know, it could be used as a tanker jet for the military, or it could be used as a commercial aircraft for airliners.
I see. So at this point, Boeing sort of shows their hands. So now Douglas knows about the commercial jet pivot that Boeing took. So I would imagine the prototype is there to now actually try to garner public interest sign contracts perhaps with airlines. So what happens next?
Yeah, so you would think that Boeing rolls out this new dash 80 prototype and it's like nothing anyone's seen before. You'd think there'd be a lot of interest, but something would actually happen that would cause interest in a jet airliner to reach an all time low.
So I mentioned earlier that the technological innovations Boeing discovered at Vulcan Road and implemented on the dash 80, like the swept back wing, and the potted engines allowed the dash 80 prototype to be not only more performant than the comet, but also safer. Oh, did something happen to the
comment?
Yeah. So another critical feature that Boeing added to the dash 80 was they designed it with circular windows and hatches. And this might not seem obvious at first, but it was actually a lesson learned from Boeing's previous experience with pressurized airliners. Remember, they had built the world's first pressurized airliner, the strata liner previously. Mm-hmm. So Boeing is something of an expert when it comes to pressurization.
Now this detail will turn out to be critical because at the same time as the dash 80 was being introduced, the comet was actually grounded by several fatal crashes.
Oh, no kidding.
Three comets were mysteriously destroyed in flight due to an unknown structural failure. They just spontaneously broke up over the Mediterranean. And then there was also an incident in India, and no one knew what had caused this. But finally, after the third incident, all, all the comets were grounded. And the British conducted an in-depth investigation to determine why these aircraft were failing. So after an exhaustive investigation, they determined the cause was actually metal fatigue.
And so the comment in contrast to the dash 80 had square windows in hatches, and this concentrates fatiguing stresses at the corners. And then this fatiguing stress was accentuated during the repeated pressurization and depressurization of the cabin during these high altitude flights. No kidding. Yeah. Remember I mentioned earlier the comet flew higher than any commercial aircraft ever had before.
So at the time, most of the airline industry didn't know enough about the effects of repeated pressurization cycles on an airliner. Boeing, however, was on the leading edge of pressurized flight research and had designed the dash 80 with rounded windows and corners to evenly distribute the fatiguing stresses.
That's so interesting. Most people don't know that this compression and decompression cycle, that pressurized aircraft undergo. Is so hard on the aircraft that it is effectively the best measure of the age of the aircraft. In other words, the number of pressurization and depressurization on an airframe is equivalent to like miles on a car.
It's basically like inflating and deflating a balloon thousands of times, but with much higher pressures.
So I imagine that this tarnishes the British Jet's reputation, and this basically leaves the commercial jet market wide open for Boeing.
It does, but it also tarnishes the image of jet aircraft in general after everyone sees these horrifying accidents of the comet. Nobody wants to ride on a jet airplane. None of the airlines wanna buy one. Right? So there's not much interest in the dash 80 when it first comes out, because people kind of had this bad taste in their mouth from what happened to the comment.
But Bill Allen presses on with the development of the dash 80 prototype and has its first test flight in June of 1954 for this first test flight. It's piloted by test pilot Tex Johnston. And so Steven Tex Johnston is quite the character. You know, it's like he walked out of a Hollywood script or something. Clive Irving in his book, jumbo, describes him as part cowboy, part scientist.
Johnston fell in love with airplanes at the age of 11 when he saw a pilot land in a cow pasture, and he just decided to hitch a ride with him. After that. He started out flying as a daredevil in the circuses at the time, and this is again, like early wooden by planes. So he is a bit of a risk taker and he eventually became a test pilot and he was actually one of the first test pilots to pilot a aircraft with jet engines and also the swept wing design.
So he is a good fit for Boeing and he has this interesting ritual of every time he tests a new plane, he wears a new pair of cowboy boots. He is also seen sometimes wearing his Stetson cowboy hat as he's piloting these test aircraft.
Just the name, I'm just imagining a character just from the name alone. I mean Tex Johnston.
Yeah, it's great. He's known for sometimes that's been kind of reckless and he's a partier. But he also interestingly, has this engineering mindset, which is really invaluable for Boeing because he's great at communicating with the engineers and letting them know exactly how the aircraft needs to be redesigned or modified to work for the pilot.
So this character texts Johnston joins Boeing in 1949 as the lead test pilot for the XB 47, and then he goes on to be the lead test pilot for the dash 80 and the first test flight actually goes really well. Johnston likes the maneuverability of the aircraft. He thinks it flies well. But there is just one concern, and that's the tendency for the dash 80 to exhibit what's called Dutch roll. What is a Dutch roll?
So the Dutch roll is this tendency for the aircraft to kind of wiggle and roll side to side unexpectedly due to a reduction in directional stability. And so an uncontrolled Dutch roll can actually lead to a loss of control and eventually a crash if it's not damped out. Interestingly, swept wing aircraft are actually more susceptible to Dutch roll because they inherently have less directional stability.
Johnston had already encountered this Dutch roll issue on the XB 47, and there it was solved by installing a yaw damper that automatically damped out oscillations before they could grow.
Is the yaw damper a passive system or an active system?
Active, but it's all done in the background. The pilots don't have to do anything. It just automatically damps out these Dutch roll oscillations.
No kidding. So this is an active system, which means there's moving parts, which means that it's a point of failure. So this could break and now it's up to the pilots to handle the Dutch roll.
More on the Dutch roll later. But for now, engineers just implement the same fix as they did for the XB 47, and they installed this ya damper. And so the test flight program goes well, and Alan decides to invite some of the leading airline executives to Seattle to evaluate this new prototype. He's trying to get feedback from the airlines and kind of garner some attention in the wake of the comet disasters.
So during a boat race that summer on Lake Washington in Seattle, Alan hosted several of these airline executives on the company boat, and he arranged for Tex Johnson to perform a flyover in the dash 80 during the race.
So Johnston took off from Boeing Field with a crowd of about 200,000 people gathered on the lake shore, and he brought the dash 80 in at a speed of almost 450 miles an hour, and skimmed just 300 feet above the lake with these turbo jet engines screaming and drawing everyone's attention. Then Johnston pulled up on the dash 80 into a steep 35 degree climb, and circled around for another pass.
This time, as Johnston crossed high over the lake, he flipped the plane over and looped into a barrel roll. And so as he flies over these airline VIPs on the lake, the plane was actually upside down.
Holy smokes.
So there's this famous picture of a passenger looking out over the wing, and the engines, instead of hanging under the wing are actually sticking up because the airplane is upside down.
Wait, was this, was this planned? Or, or, or is this an accident?
So planned by Tex Johnston, but not planned by Bill Allen.
Okay. So Bill Allen was shocked to see this?
Yeah. Bill Allen can't believe his eyes, but he fakes it because he is in front of these airline CEOs. But Johnston actually circles around and you know, at first Bill Allen thinks maybe this is an accident, I hope he's okay. But Tex loops around and does it a second time. He does it again. He does another barrel roll. And so at this point Alan is furious, but he kind of controls his temper. You know, because a barrel roll is like a fighter jet maneuver. Right.
It's not done in like a commercial airplane.
And if this goes bad, it could totally tarnish Boeing's reputation. Absolutely. It's, it's
pretty high risk.
So what does he do? What does, how does Bill react to that? I mean, does he call him or,
so again, he's, he's calling in front of the airline CEOs. 'cause everybody loves it. Everybody else thinks it's planned. Yeah. So they're applauding. They're like, oh wow, this is great. They love this show. But then the next morning Alan calls Johnson into his office and he says basically, what on earth do you think you're doing yesterday? And Johnson answers. And he is basically like, I'm selling airplanes.
No kidding. And
he goes on to explain that it was a safe maneuver. He had planned it. There was no risk. And Z Alan's response is just, well, you know that now we know that, but just don't do it anymore. And it goes on to say the whole future of this company is in that airplane.
Yeah. I mean, if that would've gone wrong, I mean, that
could have just been the end of Boeing. And not only that, it's the signal it sends to the airline executives. I think Clive Irving puts it really well when he says Boeing didn't want people to get the idea that its airliners were tested by cowboys. Airlines didn't buy planes the way the Air Force did. And so you know, Tex Johnson, he's a military aircraft test pilot, and so he's used to like you sell a military jet by doing these crazy barrel rolls, right?
But while it might impress some of the airline CEOs, they don't wanna see their passenger aircraft doing barrel rolls and high speed maneuvers. Yeah, exactly. Wow. So at this point in the mid fifties, Boeing's competitors, Douglas and Lockheed are still building propeller driven airliners. But the dash 80 success is making it more and more obvious that Jets are going to be the future.
And so the engineers at Douglas realize this, and they urgently begin work on a jet airliner of their own, hoping that they can catch up to Boeing before it's too late, and eventually reports filter back to the Boeing team that Douglass has started pitching airlines on its own version of a jet called the DC eight. But despite the previous humiliations of losing out to Douglas, the Boeing engineers don't really take this that seriously.
They don't ask for the airline's input on their design, and they still believe that their technological superiority will be enough to win the airline's business.
Wow, that's bold. They're not only ignoring the competition, but they're still ignoring the customer as well.
Yeah, they're kind of, you know, still isolated in Seattle, just doing their own thing. They're really confident because they have the best jetliner prototype of any company. And you know, importantly, at this point, Douglass doesn't have a design, they don't have a prototype. They're just kind of starting to pitch customers.
So you know where Boeing went on this bet and they designed the dash 80 prototype and then in spectacular fashion reveal it to the airlines and said, look at this awesome airplane that we designed. Don't you wanna buy one? Douglass did the opposite. Before they even kick off their design, they go to the airlines and say, what would you like a Jetta airliner to be like, let me get your input. And they start the design process there. So two very different ways of trying to solve a problem.
And it's gonna be interesting to see what works better.
Okay, so Boeing reveals this prototype to the world. They do these test flights that impress some perhaps scare others. Do they have any orders at this point? For this airplane?
No. So no orders yet. And you know, the dash 80 is just a prototype, so they're not gonna get any orders from it, but they do generate enough interest within the airlines to commission the production and design of a full-blown jet liner. Alan puts Pinnel and Steiner to work on adapting the dash 80 design to build this production Jet airliner, the 7 0 7.
Alan also picks an engineer named Milt Heinemann to perform the interior design for the 7 0 7 because, well, a lot of things from the dash 80 could be carried over to the 7 0 7. There wasn't any interior design done. You know, this was just a test prototype, so it didn't have passenger seats and bathrooms and that kind of thing. But interestingly, Heineman's only previous experience was doing the interior design for bombers designed for the Air Force.
So these are designed for military pilots and nuclear bombs. It's not really the same kind of design you want to have for a passenger jet. So Heinemann brought in a design firm named Walter Durwin, Teague and Associates to consult on the interior design for the 7 0 7 and Tegan Associates basically go on to design the basic template for what the inside of a jet looks like even today.
They designed this cabin to be bright, clean, and efficient in stark contrast to what previous airliners had been styled to kind of look like an ocean liner because they had these window curtains and tablecloths and nautical designs. But Tegan Associates decide that it's time for a new design language for the high speed jet age.
Okay, so Tegan Associates. Are fundamentally responsible for the interior that we are also familiar with today of the modern aircraft.
Yes. Some of the new design features that they include are windows for every aisle. Prior to that, not every aisle had a window. And then they also designed this cluster of controls called the Passenger Service Unit. And that's basically the same cluster that we're all familiar with today that kind of sits above the seat and it has the light, the air conditioning, the flight attendant call button, that's first designed by Tegan Associates for the 7 0 7.
And overall, the design language of Tegan Associates is to optimize the airplane to be cleaned quickly and for faster turnaround times, because these jets are gonna be faster than the propeller airliners. So it's gonna be much more important to turn these around quickly so they can be carrying passengers as much as possible. So to sum up, instead of a flying ocean liner, the inside of a 7 0 7 was given a sleek and efficient modern design.
Now, as the engineers at Boeing are finalizing the design for the 7 0 7, there's an internal disagreement on how wide the passenger cabin should be. And Stephen, the width of the cabin is one of the most important factors for the airlines because it determines how many seats with paying customers can be added. And the width of the passenger cabin is also very much a one-way door decision.
A lot of modifications can be made to an aircraft after the initial design is complete, but changes to the fuselage and the overall structure require a change to basically every major system, and it's usually cost prohibitive. Yeah, I think
you need to design an entirely new airframe and therefore an entirely new
aircraft. So when it comes to the width of the cabin here, Boeing has only one chance to get it right. Now the dash eighties passenger cabin was based on the two plus two seating of Boeing's last commercial aircraft, the Strato Cruiser, and that was 132 inches wide and it basically allowed for two seats on either side of a single aisle.
But at the same time, remember I said that Alan had hedged his bet and engineers were also working on another idea for the dash 80, a derivative Air Force tanker to refuel the B 52. And the engineers had actually designed a wider fuselage for that plane that was 144 inches wide. Side note here, this plane would go on to become the C 1 35 military transport and the KC 1 35 tanker, both of which are still used by the US Air Force to this day.
So penal and Steiner get permission from Allen to use the wider 144 inch fuselage from the C 1 35 for the 7 0 7,
so they get permission from Bill Allen. So Bill Allen is involved in the
technical design. Yeah, he's involved in the technical design, but he's also really interested in, you know, what are going to be the cost and time implications of a decision like this. And so this new wider cabin for the 7 0 7 results in a two plus three seating configuration. So basically three seats on one side, two seats on the other side of the aisle with 140 passenger seats compared to about a hundred on competing propeller airliners at the time.
Now at the same time, Douglass is also working on their own commercial jet, the DC eight, and they started off behind Boeing and technical understanding of the jet engine and the swept wing design. But Douglass did have one key advantage, and that was the respect of the world's major airlines. Douglass was also kind of helped out by a delay at Boeing during the design of the 7 0 7.
So interestingly, since Boeing was also selling this KC 1 35 military tanker to the Air Force, they needed permission from the government to use the same tooling and assembly lines for the 7 0 7 because obviously it's a tremendous efficiency advantage if you can use the same production line for two aircraft. But since the Air Force wanted to ensure that Boeing could produce a certain number of KC one 30 fives for military purposes, they needed permission to use that same tooling for the 7 0 7.
And this ended up resulting in a delay of several months while Boeing waited on the Air Force to grant them this approval. And so during that time, Douglass worked closely with the airlines on the design of the DC eight. They decided on a design that was remarkably similar to the 7 0 7. It would also feature four turbo jet engines and swept wings. But interestingly, it would have a 147 inch wide passenger cabin, and that's three inches wider than the 7 0 7.
And critically, it allowed for a three plus three seating configuration or 165 seats to the seven oh sevens, only 140. So despite being only a design on paper at this point, the DC eight is a favorite for the airlines. One because it's got more seats and it can carry more paying passengers. But also they've helped design it. And so. They've been able to provide their input and influence the design of Douglas aircraft.
And interestingly, Douglas kind of stirs the pot a bit and they tell the airlines that Boeing is once again trying to sell them just a secondhand military design. So they point to the KC 1 35 tanker and they say, oh, you don't want just another Boeing derivative of this military jet. You want something that's purpose built and that is gonna be the DC eight.
Yeah, this is interesting. So Boeing has the lead here time-wise, but Douglas has customer input. I wonder who's ultimately advantaged here, first to market, or the one who's closest to the customer.
It's an interesting matchup. And after the failure of the come, you know, Boeing kind of thought that they had the whole jet airliner industry to themselves. But Douglass has caught up remarkably fast with the huge investment in a aircraft of their own. So as Boeing and Douglas are finalizing their designs for the DC eight and the 7 0 7, it all comes down to what are called launch orders.
The success of any new airliner hinges on these pre-production orders that airlines place to basically commit to buying a certain number of this new design. And at this time, there were three key airlines that basically determined the direction for the entire industry. Those were Pan-American World Airways. United and American Airlines, and these were the largest and most influential airlines.
And all the other airlines would basically follow their lead when it comes to which plane should they buy. So whoever can win the launch orders for these three airlines will dominate the jet age. Maynard Pinnel kicks it off by leading a delegation of engineers to meet with United, and at this time he's feeling confident because he knows Boeing has the most technologically advanced jet.
But unfortunately, Pinnel is in for a surprise because Douglas has already been working with United to design their DC eight. So when Pinnel arrives, United shows him this mockup of the 7 0 7 and the DC eight passenger cabins. And like I said before, the DC eights cabin is actually three inches wider, but this three inches allows for the three plus three seating configuration.
And it also makes a disproportionate difference because Douglas had also lowered the cabin floor so that the shoulder and head room was significantly better compared to the 7 0 7. So when penalties these mockups, the difference is so obvious that there's not even room for negotiations with United and all of United's pre-orders go to Douglas.
Wow. So right out the gate, Boeing loses one of the three major airlines.
Yeah. So it's Oh, for one for Boeing. And Alan realizes they're in trouble. They had viewed the DC eight as this half-baked clone of the more advanced 7 0 7. But now Douglass has just stolen all of the United launch orders and risk compromising orders from other airlines as well. So United's decision sends this message to the other airlines that Boeing is really still too arrogant to listen to their customers.
And for Alan, it's looking like Douglas will go on to dominate commercial aviation for 30 more years. And Steven, for me, this highlights another critical leadership lesson that selling an idea or a product is just as important as the idea or the product itself. And to me, the Boeing engineers are just thinking about their product from an engineering perspective. They're designing the plane they want, not necessarily the plane the airlines want.
And so on paper it might be more technologically sophisticated, but they're not doing a good job of selling that to the airliners.
Yeah, marketing is very important. Nobody cares how technically advanced your product is if nobody knows about it. So you need to sell your vision as much as you engineer your vision. It's very important.
Well put. Now, nobody at Boeing is more embarrassed by the loss of the United Orders than Maynard Penn. 'cause remember, he left Douglas to come to Boeing. And so now Douglas is just. Wiped the floor with Boeing and stolen these launch orders. And he finds out about United's decision just as he's about to get on a flight to Oklahoma to meet with the next critical customer, American Airlines.
And so he calls Alan and urges him to approve a second increase in the passenger cabin's width to 148 inches, which would be one inch wider than Douglas, and allow for the three plus three seating arrangement plus 189 total passengers, which would be 24 more than Douglas. This sounds like it's gonna be very expensive. Absolutely, because Alan realizes the tremendous financial consequences of this.
Like we said, changing the fuselage in the cross section would require a significant redesign, and it's gonna cost time and money even more critically. The wider fuselage means Boeing will not be able to use the same assembly lines as the KC 1 35 for the 7 0 7. And we talked earlier about they lost all that time 'cause they wanted to use the same assembly line. That advantage will be erased if they widen the cabin again.
But Alan also remembers the humiliation of the Boeing 2, 4 7 losing out to the DC three and all these other times that Douglas pulled the rug out from under their feet just when they thought they had won the commercial airline industry.
So to summarize. A tax loophole ultimately convinces Bill Allen to bet the company on building a commercial jetliner. Allen puts Pen and Steiner to work to develop the dash 80 prototype with the key innovations being the swept wing design for aerodynamics and the use of jet engine technology. Eventually they roll out the dash 80 prototype and Tex Johnson does this barrel roll and that basically propels the airline industry into the jet era.
Of course, Douglas notices this and they enter the race and they've already netted all of United's jet orders. So now panel is basically fighting for the seven oh seven's life, and he's begging Alan to approve a last minute cabin with change to hopefully win over American Airlines.
Maynard Pinnel arrives in Oklahoma to discuss the launch orders with the CEO of American Airlines, but he's still waiting to hear back from Alan on his proposal to increase the width of the seven oh sevens passenger cabin for a second time when penal lands. He soon discovers that Alan himself is on his way to take the meeting. Personally penal and his engineers wait as Alan meets one-on-one with the American airline, CEO.
And after several tense hours, Alan and the CEO of American come out smiling. Alan has promised the wider cabin, and American has chosen the 7 0 7 for its launch orders. So Boeing is still in the fight with Douglas for supremacy in the jet age, but it's all going to come down to the International airline
¶ Battle with Douglas
heavyweight Pan-American World Airways. Okay. So they each have one of the three major airlines and now it's a battle for the third. Yeah, it's one for one. Douglas and Boeing. With that last minute increase in the passenger cabin, they were able to win over American, but Pan Am is gonna be a bit tougher. So Pan American World Airways, better known as PanAm at the time, they're the world's largest and most important international airline.
The Blue PanAm Globe is one of the most iconic logos of the time. You know, it's similar to the Nike Swoosh or today's McDonald's arches and am really epitomized the luxury and glamor of international air travel at the time. And this is really important because the 7 0 7 is primarily going to be an international airliner. And leading this most important airline was a legendary figure in the airline industry, known as one trip.
And one trip is this really forceful personality, but he's also a visionary. You know, he had started one of the first international airliners in the early 1930s using these island hopping sea planes. And so he built Pan Am from just this small international seaplane company into eventually having basically a monopoly on US international routes. But being a visionary, he's also known for his authoritarian style of leadership.
He doesn't really react to changes in the market like other airlines do. He creates them and he has this very distinct vision of a future where everyday people can fly across the oceans on a PanAm airliner.
And interestingly, Stephen, part of the impetus for airlines finally accepting the idea of a jet airliner as something to be feasible was like we talked about the dash 80 and its impact on the aviation industry, but also when the d Havelin Comet was first introduced one Trip, made some pre-purchase orders for the Comet, and really shocked the airline industry that he was going all in on jets.
Now, he never accepted these delivery orders because of course there were those failures with the comments we talked about. But you know, he sets the pace for the airline industry. So as soon as he decides to start purchasing jets, every other airline is lining up to make sure they don't miss out. So Boeing had struck a deal to sell the 7 0 7 to American Airlines, but at the time, American was mostly a domestic carrier, whereas Pan Am was the world's premier international airline.
And so they planned to use the 7 0 7 to fly their profitable transatlantic routes. But at the time, pan Am and one Trip, were not happy with the payload and range of the 7 0 7 because the Turbo Jett's thirst for fuel made it really difficult for the 7 0 7 to fly transatlantic routes without refueling stops.
Okay, so the 7 0 7 as designed at that point couldn't make it across the Atlantic. So what did they do about it?
So it's not that it couldn't make it across the Atlantic, it was just very difficult. They had to have a full load of fuel and depending on the headwinds and the prevailing winds, they might not be able to make it all the way. So it was kind of like a halfway solution. They could fly some routes like maybe New York to London, but it was difficult to fly Pan AM's popular route from New York to Rome.
So with this in mind, one trip summons Bill Allen to Pan Am headquarters in New York City, and he sends 'em down and bluntly tells him that the 7 0 7 is only a half great airplane. And trip said, we'll buy 25 DC eights and only 21 7 oh sevens because the Douglas aircraft just had better range and passenger payload. Reading between the lines.
What's really happening here is this is the legendary negotiator of one trip coming out and he's basically playing Douglas and Boeing off of each other to try and get the best deal for his airline. Oh, okay. So he's telling Douglas similar things that, oh, I, maybe I'll actually buy more seven oh sevens than DC eights. And so he, he's playing em back and forth.
'cause at this time, one trip in Pan Am are kind of like Apple is today, in that they have such large market share and they're such a large customer that they can really kind of force their suppliers to meet whatever their needs are. But Alan knows that ultimately he's going to buy whatever the best airplane is for his company. So Alan meets with its engineers and explains the requirements for a transatlantic modification to the 7 0 7 to fly these popular Pan American routes.
And his engineers tell him that the only way to meet trips, strict performance requirements is to redesign the entire wing to make it larger. And that's to fit more fuel, I would imagine, to fit more fuel, but also to give it better performance characteristics of increased range and that sort of thing. Oh, okay. Got it. Yeah. Got it. But it's obviously a significant undertaking because you know, next to the fuselage, the wing is one of the most critical parts of the airplane.
Yeah. It requires a lot of design time, critically, a lot of wind tunnel time. Wow.
Okay. So they've, they've already redesigned the fuselage and now they're gonna do the wing as well. Now this is starting to feel like an entirely new airplane.
Yeah, but at this point, bill Allen doesn't even hesitate because for him, pan AM's business is too important. Douglas s Gatt, United's orders, Boeing has Americans, and Pan Am is the tiebreaker here. So Bill Allen doubles down and he tells Tripp that Boeing will not only match the DC eight's range in payload, it will beat them. So he goes back to Seattle and orders his engineers to begin work on designing an entirely new wing for the 7 0 7.
And the engineers work in the wind tunnel 24 7 in three eight hour shifts for six weeks straight to design this entirely new wing and meet Pan AM's strict deadline. But when Douglass gets wind of this, they fire back by adding the new Pratt and Whitney JT four Turbo jet engines to the DC eight.
Basically, this is the next generation of the Turbo jet engines, and these offer a substantial performance upgrade and give the DC eight better performance all around that, even the newly upgraded 7 0 7 with the better wing. But Bill Allen doesn't miss a beat at this time. He's fully committed to beating out Douglas, and he immediately also adds these new engines to the 7 0 7. So both planes are using the exact same engine?
Yeah, so both planes have the exact same engines, but Boeing has this new and improved wing that their engineers have been sweating over in the wind tunnel. So Boeing delivers this new and improved 7 0 7 variant with a longer body more fuel capacity, more seats. And greater range. And this became known as the 7 0 7 dash three 20 intercontinental, specifically designed to meet Pan AM's long international routes.
So at the end of the day, the DC eight and 7 0 7 were well matched, but the DC eight's wing was more conservatively designed and turned out to be about 5% less efficient than the seven oh sevens redesign wing. But when it comes to airplanes and the economies of scale that they operate, 5% less efficient gives the 7 0 7 a tremendous advantage in performance over the DC eight. And so it turns out that the 7 0 7 intercontinental is perfect for Pan AM's transatlantic routes.
And Pan Am goes on to buy more than 60 of these modified seven oh sevens. And in the end, Boeing wins the majority of Pan AM's business and the other airlines follow suit. Pan Am was the industry leader. And so when they see that Pan Am has tilted towards the 7 0 7, it becomes basically the defacto jet aircraft for this new jet H.
Yeah. There's sort of this domino effect where once you win PanAm, you seem to
win. Everything falls into place. Yeah. Right. And that's what Bill Allen saw and why he committed the new engines and the new wing to be sure that they secured one trip and the critical PanAm orders.
But Juan Tripp still ends up ordering some DC eights.
Yeah, I mean, you know, again, he, he kind of splits his business, you know, he's also pressuring Douglass to improve their d dc eight. And so it's kind of a back and forth battle between Douglas and Boeing as they offer variations. But the seven oh sevens go on to outsell the Douglass DC eights three to one, and ultimately Boeing would go on to deliver almost 1007 oh sevens to airline customers.
But Douglas would only deliver about half as many DC eights, and eventually the 7 0 7 would be the plane that's most associated with the new jet age Bill. Allen has suffered through the humiliation of losing out to Douglas on three different commercial airliners during his tenure at Boeing. But now Boeing has surpassed Douglas as the leader in the commercial aviation market.
So I imagine that Douglas and Boeing will continue to compete on future aircraft. But for now, it seems to me that Boeing has won the battle on the first commercial jetliner.
Yeah, absolutely. This is going to be a seismic shift in the airline industry from propellers to jet engines. And so it's important that Boeing secures this business upfront, and really they learn from their mistakes of the past. And with the redesign, twice of the fuselage, the new wing, you know, they've adapted to their customers and eventually the 7 0 7 is the better aircraft.
But it's not over just yet because just when Boeing seems to have won the battle for jet supremacy, the 7 0 7 suffers a crisis of confidence in 1959, just one year after the 7 0 7 has entered service during an American Airlines training flight over Long Island, the pilots are practicing these simulated engine failures. And when coming out of the left turn, the plane suddenly begins to wiggle with the unmistakable onset of Dutch roll.
Oh, this is the issue that Tex Johnson encountered on the test flight. Yeah, but critically, the American Airlines pilots weren't prepared for this. They hadn't been told about the 7 0 7 susceptibility to Dutch roll. And so when they encountered the Dutch roll, they're not prepared. And the 7 0 7 flipped over on its back, hit the ground and exploded on impact,
not good one year after the planes released. Not good. At the end of the day, this is still pilot
error. So Steven says it's pilot error. Let's get back to that. So, you know, despite the yaw damper that was installed, the 7 0 7 was still susceptible to Dutch roll in some of these rare circumstances, and it would be fatal for inexperienced pilots who didn't know how to counter Dutch roll. The airlines realize that a fix is needed for this problem, and they ask Alan, who's gonna pay for these substantial modifications that are needed to correct the Dutch roll issue?
And this sets off an internal argument within Boeing on how to address the problem. So some argued that the incidents were due to pilot air and that it was the responsibility of the airlines to operate the plane in accordance with the training manual because this susceptibility only occurred in kind of these strange situations like they were practicing the double engine failure. You know, it was not common and it was outside of the seven oh sevens operating envelope.
But Tex Johnson believed that Boeing had not been totally forthcoming with the unexpected tendency to exhibit this Dutch roll. And he felt Boeing should stand behind the safety of its airplanes.
Okay, so I have a question. Was it Boeing never told American Airlines that there's the susceptibility, or was it They did tell American Airlines, but just American Airlines failed to communicate that and train their
pilots? Boeing never told any of the airlines about this susceptibility. You know, they thought they had solved the issue with the YA damper and they had solved 95% of it. But there was this still this 5% envelope where in strange situations, Dutch roll could occur, but Boeing didn't tell anybody about that.
Hmm. An experienced pilot. Do you know what the actual sort of counteractive input you need to
apply to the airplane? My understanding is it's a situation where the airplane is losing control in two axes at once, and so you're kind of balancing this input across two different axes. And the key thing I learned is if you're not ready for it. It can be very dangerous. 'cause once Dutch roll starts, you only have a few seconds to correct it before it gets out of control and becomes fatal. There's actually a second episode where another training aircrafting crowned a similar issue. Oh,
no kidding.
Yeah. And in this case, actually the airplane flipped over and two of the engines sheared off from the wing. But fortunately they were higher up in the sky than the first flight. So they had more time to correct the issue and they were able to land safely just with the loss of the two engines.
Now was this, this was a training
flight or another training flight? Yes. Okay. Because again, this only happens in this like weird envelope when the airplane is pushed to its limits. And so under normal flying circumstances, this wouldn't happen to a passenger flight. I see. But you know, it could if there was some kind of like double engine failure or something weird. So they're catching it early in the seven oh sevens lifespan. And fortunately it was caught in these training incidents and not on a passenger flight.
So ultimately Bill Allen agreed with Tex Johnston and he decided the Boeing would solve the issue at its own cost. So he tells the airlines, Boeing will modify the existing seven oh sevens to add more lateral stability and they're gonna do this at Boeing Zone cost. And eventually the modifications lead to a cost overrun of $150 million on the first batch of seven oh sevens. But it ends the accidents. And fortunately, Dutch roll never jeopardized any 7 0 7 on a commercial flight.
So for me, Steven, this is a critical episode here because paying for the modifications to solve this Dutch role issue shows that Alan has finally transforms Boeing's culture from this snobbish group of engineers who are focused on military aircraft and think they can tell the airlines what kind of plane they need to a more customer centric company that can work with the airlines and ultimately take responsibility for the design.
Yeah, I mean, and certainly at least, at least starting with Pan Am, to me, that really stuck out as well where Pan Am was essentially telling Boeing what kind of airplane
to build. Yeah, absolutely. And going back to the internal disagreements here, there's a strong case to be made that the airliners shouldn't be operating these planes outside of the flight envelope that Boeing have designed a safe plane as long as you operate it as it's supposed to be operated.
So it's not clear what decision Allen should make, but the fact that he decides to stand behind the safety of the airplane and compromise the first run, there was a cost overrun on the first run of seven oh sevens, but he does something invaluable and that's build trust with the airlines. Yeah, absolutely.
I would push back a little bit though on operating it out of the normal flight envelope because I'd imagine there are certain emergency situations where that's necessary, right? And so I believe it's Boeing's responsibility to build a plane that can operate under many different flying conditions that could theoretically happen within an emergency.
Yeah, I, I a hundred percent agree, but this is kind of a, an issue and attention that continues to this day. Now I'll save this bit for analysis, but wanna highlight here, this is eerily similar to Boeing's modern day issues with the MCA situation in the 7 37 max eight. Oh, right. We'll talk about it more in analysis, but it's the same issue of is it on the pilots to operate the plane as instructed by Boeing?
Or does Boeing need to make it basically foolproof and able to operate in any circumstances once the Dutch royal crisis is resolved? The 7 0 7 is an immediate success with the airlines. It was just the third jet airliner released in service, but it got the formula right and went on to pave the way for an entirely new way to travel.
You know, Steven, we talked about in the past how despite their technological superiority, Boeing had lost out to Douglas with the first commercial aircraft like the 2, 4 7, the Strato liner and the Strato Cruiser. But they finally win with the 7 0 7 and it's an immediate hit with passengers and airlines. The passengers love it because the flights are much more comfortable. Similar to the comment, it can cruise at altitudes high above the weather, so there's not as much turbulence.
The flights are a lot quieter because the drone and vibration of the propeller engines is gone, and then the travel times are much shorter as well. And so the improved passenger experience is really encapsulated in this ad that appeared in Life Magazine called The Coin, the Watch and the Flower. And I'm gonna quote from Sam Hal Verve in his book Jet Age to describe
this ad. The ad depicted a woman in a neat blue dress as well as a fresh corsage, sitting happily next to a boy holding a wristwatch to his ear. A coin was balanced on its edge, so smooth was the flight plus the ad promised. The 7 0 7 cabin will be so quiet, you will be able to hear the ticking of the watch. And the flower you bought when you left will be fresh when you arrive. And so for me, this just sums up the entire improved passenger experience.
It's quieter, it's faster, and it's smoother. And today we really take for granted. Flights may seem a little bumpy sometimes when we're taking off or landing with the turbulence, but you gotta remember prior to that it was much louder and you were experiencing that turbulence the entire time because you were flying through the weather.
That really stuck out to me because today, from my perspective, I find flying on commercial aircraft to be quite loud. So it's quite stunning to me, frankly, that the loudness we hear today is a substantial improvement over piston aircraft from the past. So we certainly are taking it for granted.
The airlines also loved the 7 0 7 because of its efficiency. Jet travel on the 7 0 7 was not just an evolution of the propeller driven airliners. It was revolutionary and it changed the entire business model for how airlines operated. The increased speed and passenger payload of jets like the 7 0 7 created a four to five x increase in per plane productivity over propeller airliners.
Because I'm imagining also the increased speed not only gets them there faster, but you can now use the plane more because it's not in the air as much.
Absolutely. And just to put some numbers to that idea, in 1954, pan Am used 147 propeller aircraft to fly 1.8 million passengers across the Atlantic. But once the 7 0 7 was introduced, they needed just 36 7 oh sevens to transport the same number of people. Wow. That's
ama, that's like four times fewer. That's amazing.
Yeah, so you gotta imagine that if you're an airline, you have to buy fewer airplanes. You have less maintenance and operations costs because they're flying much faster, so you can use them much more frequently. And then they're also carrying more passengers per trip. So it's really a revolution in the way the airlines operate.
And so for all these reasons, the 7 0 7 went on to pave the way for fast and regular air travel and was really the nexus and the beginning of air travel today as we know it. The 7 0 7 for this reason was known as the plane that shrank the world. And shortly after it entered service, for the first time, more people crossed the Atlantic in planes than on ships.
And so for me, Steven, that just encapsulates everything you need to know before the 7 0 7, before jet airplanes travel on propeller aircraft to cross the Atlantic was, you know, something that businessmen used if it was a really urgent trip. Or you know, maybe the president used when he went to do the negotiations after World War ii. But now finally, these planes can fly so much faster and so much more comfortably that that's the default way to travel across the Atlantic.
This also signaled the beginnings of the transition from the luxuries of the golden age of flying to the mass air travel focused more on economical and widely available flights that we recognize today. And for the first time, led by Pan American and one Trip Airlines started to offer a tourist or economy class. 'cause basically before this, all flights had just been first class. So just to put into perspective the dramatic change in flight times and flight cost.
I wanna kind of break down a trip from New York to London in 1946 on a Douglas DC six, which was the state-of-the-art propeller aircraft. This would take about 15 hours by 1960, just 14 years later, flying on a 7 0 7. You could accomplish the same trip in seven hours, and it would be a direct flight. The propeller driven aircraft cost would've been about $11,000 in 2020 $5 to cross the Atlantic.
Oh, no kidding.
But the 7 0 7 cut that more than half down to $4,500. It's still really expensive to cross the Atlantic. $4,500, that's a lot of money. But compared to $11,000, that's a significant change. And also, there's a new word that gets created because these jets are traveling so quickly that for the first time, jet lag becomes an issue. You can imagine if it, if it takes, what did I say, 15 hours to cross the Atlantic, like it's not really gonna be the same day by the time you left.
So jet lags not an issue. But if it's only seven hours, you can, as they said, have breakfast in New York and dinner in London. And so jet lag is a issue for the first time. But then just to put a cap on this idea, Steven, today, a flight across the Atlantic from New York to London on a modern jet liner like the 7 87 still takes about seven hours.
The cruising speeds are about the same, so it takes about the same amount of time, but the price has decreased from in 2020 $5, 4,500 to fly on the 7 0 7 versus today I looked up prices. It's about $700 to get a flight. Yeah, that's incredible.
I mean, that's like an 80% decrease or so. And what's crazy to me is that I know that there are certain flights you can get at least one way trips for like in the three hundreds, sometimes two hundreds. So it's just amazing how far we've come even, even since then.
Yeah. But what's really interesting to me is, like I said, the travel time is about the same. So interestingly, I think if you would've asked people, you know, shortly after the 7 0 7 came out, they probably would've thought that travel times would continue to decrease. And that was kind of the idea was supersonic flights in the Concord. And from our vantage point in 2025, we know that supersonic commercial air travel never really panned out. So the flight time is about the same.
And all the changes in air travel since then have basically been in reducing cost. And so just to summarize the outcome of these dramatic changes in how the airlines operate, the lower cost in the 1960s, after the introduction of the 7 0 7 international air travel would grow at a rate of 15% per year. Yeah, that's a huge increase in anything but 15% per year in increased air travel is just an explosion in air travel, right? Yeah, absolutely.
And with the success of the 7 0 7 Boeing is the leader in this new and growing market of commercial aircraft. Capitalizing on the success they would go on to produce several successful variants to extend their market share using the same 7 0 7 fuselage and kind of the same idea of the 7 0 7, they would develop the 7 2 7, which was a slightly smaller airplane focused on medium haul domestic flights.
They would make an even smaller airplane called the 7 3 7 for these short range flights out of small airports. Interestingly, another famous adaptation of the 7 0 7 was to be used for Air Force one flying the US President. So it's kinda interesting how this happened In the mid fifties, Americans were embarrassed and it was kind of a, a public scandal when Soviet Premier Nikita Khrushchev became the first head of state to fly on a jetliner, the Soviet Tupelo TU 1 0 4.
When this happened, it's like I said, a bit of a scandal. And so the White House immediately ordered three modified seven oh sevens to serve as Air Force one, and this plane went on to serve presidents Eisenhower through Reagan as the presidential transport.
So prior to that, I imagine the president was using a piston aircraft.
Yeah, a piston, propeller driven aircraft. Yeah. Yeah. So can't have the Soviets in a more advanced presidential aircraft, right? Of course not.
Wow. So Boeing ends up winning ultimately. I'm curious though, what ends up happening to their competitor, Douglas and all these other people who helped build the airplane,
the Douglas Aircraft Company, they would go on to compete with Boeing for several more years. They would introduce some variants and really compete with Boeing on the short to medium range flights like the 7 2 7 and 7 3 7. But by the seventies, Douglass was kind of on the downswing, and they had designed their last new aircraft. Actually, in 1967, Douglass merged with defense contractor McDonald to create a new company called McDonald Douglass. Oh. So that's where that comes from.
Okay. But eventually Boeing would go on to drive all of its competitors, Douglas and Lockheed, out of the commercial airliner industry. And so McDonald Douglas eventually actually merged into Boeing in 1997. On paper. This looked like a merger where Boeing had the upper hand. But in reality, a lot of people in the industry say that this was kind of the beginning of Boeing's present day decline and troubles. Because a lot of the cost-focused management techniques and some of like the cultural.
Rot, you could say from McDonald Douglas was infused into the Boeing company and started a big cultural shift from the Boeing that we talked about in this story.
As soon as you said that, that started their decline. That is exactly what came to my mind. If you inherit a failing company, you also inherit their failing culture and things like that.
So to follow up on some of the engineers who worked on the 7 0 7 project, Maynard Pinnel, who along with Steiner, had led the design of the 7 0 7, remember, he had come from Douglas and it was his vision to see Boeing become a leader in the commercial aviation industry. Well, that vision was realized and Pinnel actually went on to be very important in developing the 700 series family of passenger jets, like the 7 2 7 and 7 3 7.
And then after that, he would go on to lead Boeing's Supersonic transport project, which would be known as the Boeing 2 7 0 7 Tex Johnston, the kind of crazy barrel looping cowboy test pilot. Unfortunately for him, as Boeing became more profitable and more corporate, Johnson's freewheeling like Cowboy way of doing things was not welcome. Bill Allen never really forgave him for the dash 80 barrel roll episode and how he almost cost the company at that time.
Yeah,
Johnston was eventually placed under a manager and his direct access to Bill Allen was cut off, and shortly thereafter, he quit as head of test flight and moved on to the aerospace division. And so really this was kind of the end of the era of these barnstorming daredevil test pilots. Going forward, Boeing would be much more corporate and professional, and for our hero of the story, bill Allen, he gets to see his risky bet on the dash 80 paid off.
And finally, after years of suffering under Douglas as the leader of the commercial airline industry, he got to see Boeing overtake Douglas for the dominance of the airlines business. Bill Allen would continue to serve as president of Boeing until 1969, and then he would lead as chairman until 1972 when he would retire.
It's hard to underestimate Bill Allen's impact on Boeing, but to try and sum it up during his tenure, he increased Boeing's valuation from just $14 million to 3.3 billion when he left. That's incredible. That's over what, 200 x?
Yeah. Yeah. He drove a massive amount of value, and he wasn't even done with the 7 0 7 because in the late fifties, after the incredible success of the 7 0 7, Alan is already looking to the future and another gamble that would submit Boeing status as the world's premier commercial aircraft manufacturer. So despite the success of the 7 0 7 international air travel still remained primarily a luxury for these wealthy businessmen, celebrities, and politicians.
With the introduction of jet aircraft, wealthy travelers became known as the jet set, and they were photographed flying in these designer clothes, still sipping their glasses of champagne on their way to exotic playground destinations like Rome or Rio de Janeiro. But for the average person, crossing the Atlantic by air was still only a dream, even as the 7 0 7 was shrinking the world.
Bill, Allen and Pan Am president one trip, were already making plans for their final act, an airliner more than two and a half times the size of the 7 0 7, that would finally bring the dream of quick and safe air travel to the masses. So this is the part of the show now where we break down some of the themes and takeaways that we learned from the story.
And to start us off, Steven, I wanted to kind of explore this idea of what led to Boeing's success in the jet age when they had failed three times before in the propeller age to be successful with commercial aircraft. And for me, there's kind of three key ideas, and I'd like to get your feedback on these. The first, and I think the most important is, you know, I was trying to think about like what changed because Boeing had tried with three different aircraft to beat out Douglas.
They'd all been failures, and then what changed? So kind of the easy answer would be to like, well, there was. This new jet engine technology and Boeing was more technologically advanced and that's how they were able to win out. But I don't think that tells the full story because even in their failures, Boeing had been more technologically advanced. You know, the 2, 4 7 was one of the first all metal airplanes with a mono wing design.
They had the first pressurized airliner, but they still lost out to Douglas. So I don't think it's just technology. I think the key difference here was leadership, and I think it was Bill Allen and specifically I think Bill Allen saw the potential for Jet Airliners. You know, he took that flight on the XP 47 he saw for himself and he had this vision and he gambled on it.
He committed the company to it and he was most importantly willing to change the company's culture to adapt to the evolving aviation market.
Yeah, and and I would also add to that by saying Boeing was
¶ Analysis
originally a company where they just sort of built their own products and expected customers to like them. But it seemed in, for the 7 0 7 was the first time where they kind of pivoted to listening to customers. All the airlines wanted a wider fuselage and then at least Pan Am wanted more range. And so, yeah, it just struck me as the first time Boeing started listening to customers. And that was a direct result of this culture change that Bill Allen initiated.
Yeah, absolutely. And you know, he not only drove this culture change by. Supporting some of the visionaries in the company like Maynard Pinnel who had this customer-centric idea, but also he backed it up with his decisions. So, you know, it's, it's one thing to enforce a culture change just with words and tell people this is how we're gonna do things.
But for me, what really stuck out with Bill Allen is when all the chips were down and he had to, you know, spend all this money to redesign the fuselage, or he had to spend all this money to redesign a new wing or to take accountability for the Dutch roll incident, he ultimately chose to go with the customer centric approach and to push back on some of the more senior engineers in the company. Yeah, I absolutely agree.
The other variable in their success, I think is important too, is their commitment to r and d and safety. You know, they continued to be an industry leader in research and design with the swept wing design, the potted jet engines. They had been great at this before, but they continued into the jet age and so, you know, it's difficult for a technology company to always be hitting that next technological wave.
They started out strong with the, the pressurized airliners and some of these advances, but they continued that with the swept wing design and really hit the jet age too, and kind of reinvented the company. You know, they were successful with like military bombers and propeller aircraft, but they had to reinvent their approach to be successful in the jet age.
Yeah. And it seems that their safety record showed that. I mean certainly at least compared to the Comet, the 7 0 7 was tremendously more safe.
Yeah. And you know, it's not easy to draw a one-to-one line from, you know, where is investment in r and d actually gonna benefit us? 'cause nobody could have planned for the issues with the comma and the pressurization issues that created the fatigue stresses. But Boeing was able to succeed there just because they had done all this research and were able to unmask some of those surprise variables.
And then finally, for me, I think it's difficult to measure this factor, but I think the rivalry with Douglass did play a little bit into Boeing's success.
Yeah. And I mean, that kind of takes me back to what happened with United, where DC had already gotten United on board and that sort of competition that resulted in a better airplane. The market pressure that's created by having a rival there just ultimately results in a better product.
Yeah. And I think it's kind of interesting to apply that to today. So, you know, what sticks out to me is looking at the landscape of aircraft manufacturers today. There's basically just Boeing and Airbus. Yeah. Who produce commercial jets. So it's like a duopoly, basically. Mm-hmm. But. Back in this time period, there were a lot of companies that make commercial jets.
You know, just in the US there was Boeing, Lockheed, and Douglas, and then there was also De Haviland and other companies around the world. So there was much more competition and so I think probably better for the airliners 'cause just like one trip did, he kind of played these airliners off of each other to get the plane that he wanted. I think less of that today since there's only two major manufacturers.
What do you think, Steven, anything else you think contributed to Boeing's success when they had failed so many times before?
To me the culture shift to them being more customer centric is arguably the fundamental thing that changed here. Because like imagine if they were still stubborn and they ship a plane that's five abreast and can't reliably make it across the Atlantic. I think the DC eight wins here.
Also, I guess to your point, like the bold decision making of Bill Allen and his sort of strong leadership and ultimately A CEO who was willing to touch grass and like literally sat on the XB 47 and experienced it for himself.
Another more broad lesson that I drew from this, and we talked about a little bit during the story, but it's really fascinating to me here the tension between creating something new that no customer has asked for and then listening to your customers to iterate, improve on your product. So like we mentioned earlier, you know, there's kind of two approaches you can take. There's like the. Steve Jobs iPhone approach of we're not gonna create what our customers ask for.
We're gonna create something that they didn't even know they wanted. And for me, that's kind of like Boeing with the jet airliner. When Alan commissioned this prototype, the dash 80, the comment had just had these spectacular failures and there wasn't really much demand at all or any customers for jet airliners, but they built one anyways. But then the caveat to that too is you can't just be kind of arrogant and say, well, we're gonna build what the customers don't even know they need.
They don't know what they want. Once you have that initial idea, you need to continue to iterate to get customer feedback, because in addition to releasing the first jet airliner, Boeing also worked with their customers to do things like widen the cabin, improve the range by creating a larger wing.
So to me it's this really interesting interplay between when do you create something that nobody has asked for versus when do you try to optimize and solicit customer feedback to improve a design that you already have.
Yeah. That's really interesting. You know, you, you just kind of saying that makes me think maybe some pseudo optimal approach to just product design in general is that you first need to take that bold first step to invent a product that nobody asks for, but then you immediately follow that up with customer feedback. So maybe that's like a general framework that can make our product successful. And it seems that Boeing certainly did that here.
So Will, another idea that I thought was interesting from this story is sort of like, when do you want to build a product from scratch versus building on top of something that already exists? There's a sort of tension between the two because if you build something completely from scratch, you can spend a lot of cycles sort of reinventing the wheel.
But if you build on top of something that already exists, you might save some of those cycles of reinventing the wheel, but you're also marrying yourself to sort of legacy to techniques or product features that are no longer relevant in the new product that you're kind of shipping. And I feel like we kind of saw that here with the 7 0 7.
Yeah, so what this reminds me of the story is Boeing's approach before the 7 0 7 was basically to adapt these military aircraft into commercial aircraft. And so like with the, I believe it was the Strato liner, it was just adapted from the B 17. Strato Cruiser was adapted from the B 29, I think. So, you know, it makes a lot of sense from a business perspective that, hey, we already have this military airplane.
It's been kind of subsidized by the government and you know, that they got funding from the military to initiate the project. And so it's a lot easier to kick off a commercial plane if it's just a derivative of the military aircraft. But kind of to your point, you keep those gremlins or problems or you know you're trying to fit a square product into a round hole.
Yeah. Yeah, definitely. I think
the ultimate approach that Boeing settled on is kind of interesting 'cause Alan had them build the dash 80 prototype, which was basically just a prototype that could fit kind of both areas. So he took this like generalized solution and then they specialized it for the military with the Casey 1 35 and then specialized it for passenger transport with the 7 0 7. So, I dunno if maybe that's a solution is to develop a generalized solution and then specialize
it. It seems what you're kind of saying here is with this tension of building on a legacy platform versus starting from scratch, one sort of optimal way of doing this of sorts is to build a generalized platform and then take opinionated stances on various specialized uses of that platform, whether it be military tanker aircraft or a commercial jet passenger aircraft.
I think at the end of the day here, the, the, the sort of takeaway here is don't try to build a commercial passenger jet on top of a military bomber, but maybe it's okay to build a military bomber and a commercial jet on just a generalized platform.
Yeah. Yeah, I'd agree with that.
Yeah.
Another idea I got from this story, and it really stuck out to me because anyone who listens to the episode about the Empire State Building, we also discussed this. And it's this idea that selling your vision or your product is just as important as selling the idea or the product itself. And you know, this stuck out for the Empire State Building because it wasn't just enough to have the tallest building in the world.
They also had to sell it and advertise to people and make the public believe that it was the tallest building in the world. And we see that again here in the 7 0 7 story when with all these failed commercial airliners, Boeing had the best technology, but they didn't sell it to their customers, and they didn't do a good job of telling that story. And so Douglas, who was good at selling to their customers, was able to leapfrog Boeing even though they didn't have the technological superiority.
There's something here with the 7 0 7 that I thought was good marketing. There's a little ingredient in here, and I think it was calling it the 7 0 7 there. There's something about 7 0 7 just as a branding name that just lands better than DC eight.
Yeah, that's a, that's a good observation. And I think it's part of a larger transformation that also took place in Boeing, and we didn't have much time to go in depth here, but Boeing was a company that didn't do a lot of marketing beforehand. They thought that it was just enough to design a great airplane and the product would sell itself, which is like a refrain I hear a lot of times from engineers and technology companies. Yeah,
it's like an more of an engineering mindset company.
Absolutely. Yeah. But what Bill Allen discovered basically with the 7 0 7 is that if they wanna go head to head with Douglas, they need to also have a great marketing department. And so one of the things they did for the 7 0 7 when they were really ramping up the competition for the airliners pre-orders is they had like this big extravaganza in New York City where they rented out like this old coffee factory to actually put a 7 0 7 in there and bring airline executives to tour.
And they did a lot of these big events. The barrel roll over Lake Washington, I think would fit into this category too. And so they really try to sell the airplane, not just on its own merits as a technologically advanced jet liner, but they actively kind of court the airlines and put together like for the first time, it seems like to me, like a real marketing department at Boeing.
Yeah. Engineers tend to fall into the mindset that a great product will sell itself. But yeah, I mean, you need marketing at the end of the day, and I think Boeing evolved very well here in this story.
Yeah. I think it's doubly true for the airline industry where you're selling these relatively low volume, but high price tag products, right.
Yeah. And you know, something that also sticks out to me will, about the 7 0 7 is that it was the aircraft that effectively defines the modern jet liner we see today. Both like the interior feel of modern jets that we're all familiar with to the physical appearance of the airplane on the outside and so on. And to me that's pretty incredible.
Yeah. And I agree. I think there's almost like a general principle you could apply here that when there's a new technological paradigm or a shift in how the market works, the first product is really gonna set the tone for 50 or 60 years in some cases of Yeah, yeah. What the industry is gonna look like. I think a good comparison here would be like the iPhone, where the iPhone was the product that really got the smartphone right.
And even today, every smartphone is kind of a clone of the iPhone in a lot of ways. Yeah. Just like some micro iteration on that original design 20 years ago. Yeah. It, it set the design and like the overall idea for this entire smartphone paradigm. So it's, it's really interesting to me.
'cause I think with the iPhone and also with the seven oh seven, you can go to like these simple decisions made by just a few engineers that had an outsized impact just because it was the first jet airliner, they were doing something that had never been done before. So like, for example, the potted engines under the wings, that was a, a relatively straightforward idea that the engineers came up with.
But at the time they didn't know that all commercial airlines basically to this day have potted jet engines under the wing. But it also to me, really highlights how well they got it right with the design of the 7 0 7 because it's been like this evergreen design.
And to me that's the ultimate test of a design is that thousands and thousands of engineers have iterated on commercial jet designs over the years, but they haven't come up with anything better than some of these very fundamental concepts.
And honestly will, that's such a great point. Like to me, this sticks out as like sort of an iPhone moment and that you know, you have an iPhone moment where decades after the original product was unveiled, it doesn't change much and that just shows you how right that they got it originally. So Will, do you have anything else on your notes, uh, that you wanna finish us off with?
Yeah, I had one more idea that I think really highlights the leadership of Bill Allen and Boeing here. And that's the importance of taking the long-term view as a leader. And I think Bill Allen is a great example of this. He definitely took the long-term when he gambled all in the dash 80 when he committed to winding the passenger cabin and then also paid for the modifications to resolve the industrial issue.
We didn't talk about this too much during the story, but Alan also sold the initial seven oh sevens at a loss to gain market share and establish Boeing as a key player. So I think this is just a really good example of how Alan, he's been with the company for a long time. He's part of the Boeing family, so to say. He's not just this transplant CEO. And so I think that allows him to take the long-term view. You know, he has grown up with Boeing. He wants to see it become a great company.
He's seen the humiliations of losing out to Douglas and so he's not interested in quarterly financial results or boosting the stock price. And he is able to do a lot of decisions that I think A CEO that is focused on the short term wouldn't be able to like betting the company on a big project, like foregoing short term gains to capture market share and eventually create Boeing into the duopoly in the commercial jet industry.
Now do you know, was Boeing still a private company around the time the 7 0 7 shipped? No, they were a public company at this time. To, to me that that makes sort of Bill Allen as a leader that much more impressive in his long term thinking because as you know, publicly traded companies feel a lot more pressure to sort of deliver short term results. But Bill Allen's sort of standing strong as a leader of a public company is just all the more impressive.
Yeah, and I think that goes back to the idea that I think in a lot of cases, hiring. A leader internally can be better than even objectively better external hire, for example. You know, like they could have gone out and gotten a world class CEO to run Boeing because it's a big company. But I think Alan, just by growing up with the company and having all this experience had a lot of advantages over other potential candidates.
There was a lot of trust in Bill Allen because he had been with the company so long and there was a lot of, like basically the board of directors ultimately deferred to him because he'd been around so long. He had this vision for the company that A CEO who is just airdropped in, wouldn't be able to have. Yeah, and I imagine
once you ship a product like the 7 0 7, that earns you enough trust that any board of directors would defer to you. Yeah.
Yeah. And what really just highlights this idea of long-term thinking too, and I think this is, you know, one of Bill Allen's greatest moments is the issue with the Dutch role incident. Like we talked about, there was an issue with the airplane, you know, this vulnerability to Dutch roll. It wasn't a hundred percent clear if the airlines should take responsibility, if Boeing should take responsibility for it. But Bill Allen decides he's going to sacrifice basically the entire first run.
Like I said, there was $150 million deficit on the first run of seven oh sevens because Bill Allen said, no, we're gonna stand behind our airplane. We are ultimately responsible with the safety. The buck stops here basically. And that's a really long-term view because you know, yeah, he made up for it on the back end with more Boeing sales. But if he had deferred and said, no, actually we really need to pump our stock price this quarter, so we're not going to accept a loss here.
That would've been a short-term gain, but they could have really lost out on dominance of the commercial airline market. And what's even more incredible here to me, is that this is in stark contrast to Boeing as a company today. So I wanted to bring in the recent issues at Boeing with the 7 37 max eight, and the MCA system. Just a little bit of background. So MCA stands for Maneuverability Characteristics Augmentation System, and it's kind of eerily similar to the Dutch roll incident.
Basically this new generation of 7 37 called the Max eight, it had this system on board called MCAS that was supposed to correct this tendency for the airplane to pitch up in certain situations. But similar to Dutch roll and the jaw dampener, Boeing didn't tell pilots that the system was onboard the plane. You know, in this case, they were concerned about reducing the amount of new training that pilots would need. So they kind of covered it up and left it out a bit.
But then unfortunately, it was passenger flights that this vulnerability came to the surface and a couple of flights crashed because the MCA system fired incorrectly and drove the nose of the airplane into the ground. But in stark contrast to Bill Allen, Boeing did the exact opposite. They pushed back and said, you know, the pilots should know what to do. It's in the manual. They just need to take this procedure. It's not Boeing's fault. We're not gonna change anything, et cetera.
And as we can see, you know, the idea that comes to my mind is this quote that it takes years to build a reputation, but just five minutes to lose it. And Boeing basically throws away their reputation in this example, because it's revealed in later crashes that even Boeing's fix for this sim a system wasn't enough. And they eventually had to ground all the 7 37 max eights.
You know, anyone who falls to the news, Boeing's reputation is really in shambles now because unlike Bill Allen, they kind of pushed back and they didn't assume ultimate responsibility for the safety of the airplanes. So Steven, we've talked a lot about the transformative 7 0 7, kind of ran through some of the ideas that we learned, but I'm curious what sticks out to you after listening to this whole story? What can't you stop thinking about?
You know, will, it really comes back to just how much of sort of an iPhone moment this was. You know, the 7 0 7, the design that originally shipped with that design still sort of permeates all modern aircraft design today. I mean, you take a 7 0 7 and compare it to a modern 7 87, and most people outside the airline industry probably couldn't tell the difference between the two aircraft.
Yeah, they really defined the new generation of airplanes and the fact that there's been so little change just shows you how much of a success that really was. Yeah, absolutely. That's a great point. How about you will, what can't you stop thinking about from this whole incredible story of the 7 0 7? You know,
Steven, the one thing that really sticks out to me is just the leadership of Bill Allen and I, I go back to what I said earlier about Boeing failed three times to develop a successful airliner that could beat Douglas. And so if you were taking bets when the jet age started, I personally wouldn't have bet on Boeing. They have this really poor track record. But then it's this unassuming lawyer named Bill Allen who's gonna run Boeing. Yeah, the lawyer part's incredible.
Yeah. But then he goes on to be super successful. He's exactly what Boeing need, and really importantly, he transforms the entire culture of Boeing and sets it up for success with the 7 0 7, but eventually the variations of the 7 0 7. He's instrumental in the 7, 4 7, and he really created Boeing and the airliner industry as we know it today.
So just really impressed with Bill Allen's unassuming leadership style, but how he was able to drive results and change a culture, which is not something that's easy to do at a big company like that. So ultimately, I think Bill Allen is one of these great leaders that we don't hear about much today because he is not a really flashy personality. But he's a great leader and sometimes the greatest leaders are who you would least expect them to be.
