The first non-stop transatlantic flight happened in 1919. A modified WWI bomber with an open cockpit took off from Newfoundland, Canada with a crew of two. They almost spiraled into the ocean twice in heavy fog, had to climb onto the wings to clear ice, and landed in a bog in Connemara, Ireland.

The F-82 “Twin Mustang” fighter plane, designed to escort bombers thousands of miles to Tokyo, was literally two P-51 Mustangs joined at the wing. Both cockpits were fully functional, so one pilot could sleep while the other flew the plane on missions that could last up to 12 hours.
