Nobody talks about this one. A man runs a taxi service in the sky, and the movie treats it like the most ordinary job in the world, which is the entire joke. The 1932 animation moves with a lightness that makes flying look less like spectacle and more like commuting. You watch something that knew exactly what it was and didn't need to prove anything. Comedy this quiet and confident doesn't survive into the modern era.
A pilot runs an air taxi in this 1932 comedy short. After he saves an eagle, the bird tells him where a valuable treasure lies, somewhere in a perilous land. He sets off to find it, but he runs into trouble along the way. The eagle comes to his rescue in turn and helps him bring the treasure back.
