Another inaccuracy, in 1963, I think, you needed a fourth man in the cockpit. That was a navigator to cross the oceans. I know in the early 70's they were still using navigators to cross the ponds.
True, and there would have been significantly more of a generation gap between the cockpit and cabin. All the Captains probably had flying boat time. The engineer was a professional FE and probably older than the Captain. But the most glaring inaccuracy is no one is smoking?
I know a Pan AM retired skipper who started on the boats in 1943. Then he went to a really fast airplane, as he described it, the DC-4. On to the DC-7 and the Boeing 377. His first upgrade was in the 707 and he retired off the 747 in 1985.
