An outstanding color film with post-war narration. This film is on a level with "Memphis Belle" and shows the British night-bombing effort well.
Some of the things I learned/observed: The interior of the bomb-bays and the bomb-bay doors were painted black, the nickeled "Thunderer" whistles worn on crewman's left lapels, the only 6 hour notice of target designation before take-off and the mentioning of a Lancaster's lasting only 40 hours flight time.
I was a little surprised to see the RAF service uniform - tie and all - worn by so many ground crew even when doing tasks involving manual labor.
