There is a pretty good TV
movie called "The Last Flight Out"!
It´s the story of Pan Am´s last flight out of Saigon in april of 1975!
The aircraft a 747-100 "Clipper Unity" (in the movie though a TriStar L1011 is featured) was used to evacuate Pan Am employees and their families as well as a lot of other people and orphans!
It was indeed a very impressing and brave thing they did!
The entire crew was formed by volunteers! Otherwise the flight couldn´t have been operated!
Very touching movie!
