Episode description

World War II pilots ate a bunch of carrots. Back then, people were well aware that vitamin A was critical for healthy eyesight and that carrots were a good source of beta-carotene. So in 1940, versions of high-carotene strains of carrots were being tested on pilots to reduce night blindness. This was pretty important at the time because during the 1940 Blitzkrieg, the Luftwaffe often struck under the cover of darkness. The British government issued citywide blackouts to make it more difficult for German planes to hit targets, so maximising vision among pilots and civilians was critical. 

The year before, the RAF had built the new secret Airborne Interception Radar (aka AI). Instead of being limited to land-bound detection stations, the AI Radar was on planes, able to pinpoint enemy bombers before they even reached the English Channel. 

In 1940, RAF night fighter, John Cunningham, became the first pilot to shoot down an enemy plane using AI. He eventually tallied 20 kills - 19 of them at night - and became known as “cat eye” Cunningham. But, the Poms needed to make sure the Germans didn’t know about the secret of their success. So, the UK Ministry of Food came up with a different reason: Carrots. 

Make the Germans think that carrots gave Cunningham night vision.. And just don’t mention the little Airborne Interception Radar that he had on his plane.
