Funnily enough, I recall that Martin Bull said they had taken some of the flight sequences from the " Dambusters " film in the 50's to the Star Wars 1977.
The attack on the Death Star in the original Star Wars was copied from 633 Squadron, in which a squadron of RAF Mosquito bombers have to fly up a Norwegian fiord, flak guns shooting from the sides, Messerschmitts diving from above, trying to place their bombs in exactly the right spot to destroy a German rocket factory.
