Falling Hare is a Bugs Bunny cartoon from 1943.
Synopsis
Bugs laughs at the notion that gremlins are sabotaging American planes in the skies, but as he reads Victory Through Hare Power, he encounters one on an airfield hammering a plane's wheels with a gigantic mallet and is soon doing battle with him in a flying plane.
In a finale that brings Chico Marx's speech in A Night at the Opera to mind, the plane on which the two are fighting goes into a tailspin, but runs out of gasoline and stops about six feet before hitting the ground, hanging in midair.
