Great Mysteries and Myths of the Twentieth Century (1998)

Season 1: Episode 6

After the invention of the jet engine during World War II, Britain raced ahead to produce the world's first jet liner - the Comet. It was rushed into service and after many successful trips to Africa, India and the Middle East it suddenly started to crash in mysterious circumstances. After exhaustive underwater searches, the fuselage of one particular aircraft was painstakingly tested to the point of destruction. What was found dictated the shape of all subsequent aircraft windows.
