As a young boy (6-7) I flew with my Mom on a Pan-Am Cliper from San Francisco to Hawaii. This was in 1957 I think the aircraft was called a “Connie”. Four props. First time I was ever on a plane. Great fun. We were going to meet and live my Father, a Marine, who had been transfered to Hawaii. We walked down the steps and many leis were placed around or necks ... what a place Hawaii was in the time I lived there. When we returned to the mainland (Hawaii became a State while we were there) after 4 yrs. we sailed on a ship, USS Luraline, back to San Fransico.

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.
