The Death Star sequence (specifically the trench run) was based on, and sometimes lifted scene for scene from the 1955 movie "The Dam Busters." [0,1].

Substitute these experimental "bouncing bombs"[2] for Luke force-bending proton torpedoes and you have the end of Star Wars.

It's noteworthy that two people who worked on Dam Busters also worked on Star Wars 20 years later, as described in link [0] above.
