Ghost Patrol (no wikipedia entry) is a 1936 science fiction western film directed by Sam Newfield and starring Tim McCoy. I think that's the longest plane crash I've ever seen.

Weird Wild Realm says, "It's a silly hybrid movie to be sure, but played with such endearlingly pokerfaced sincerity that it manages to entertain." AMCTV has an overview.
