TGTBT: Mysterious Ship Disappearances

Ships are usually declared lost and assumed wrecked after a period of disappearance. The disappearance of a ship usually implies all hands lost. Without witnesses or survivors, the mystery surrounding the fate of missing ships has inspired many items of nautical lores and the creation of paranormal zones such as the Bermuda Triangle. In many cases a probable cause has been deduced, such as a known storm or warfare, but it could not be confirmed without witnesses or sufficient documentation. Many disappearances occurred before wireless telegraphy became available in navigation applications in the late 1890s, which would have allowed crew to send a distress call. Sudden disasters such as military strike, collision, rogue wave, or piracy could also prevent a crew from sending a distress call and reporting a location.
