I flew on DC-3 N136PB between Key West and Marathon Key Florida in the 1980s as a kid. Just me, my brother, the pilot, co-pilot and one air stewardess on board. We sat in the cockpit as they started up and were allowed to sit anywhere we liked for the flight. It's one of my best memories ever. The pilots were aware the it was the highest time airframe and delighted us with the notion that it broke a new record every time it flew (and so we broke a record!).
Magic!
