One of my good friends was a Pan Am flight engineer in the late 50s. He didn’t mention Constellations, but he had a lot of time in Boeing 377 Stratocruisers, all of it over water. He told about actually being on a flight that got lost and had to land on a small WW 2 fighter strip on some remote island. One of those planes ditched between SFO and Hawaii after a prop ran away and destroyed an engine. They were able to do the ditching alongside a weather ship, and all were saved. A minor miracle. Two or three other Pan Am Stratocruisers were not so fortunate.
Thanks for that ... after seeing the Pan Am Stratocruiser that is the aircraft we flew to Hawaii!
