Up In The Air, Junior Birdman!

During World War II, a mechanic was making a routine test flight with a bomber that accidently drifted off course and over enemy territory. The plane was shot down and the mechanic taken prisoner.

Not knowing his area of expertise, the prison camp leader placed him in charge of the chickens. Every day he would collect scraps of metal and wood and, eventually, he constructed an engine and a pair of wings.

One morning when the officers called roll they found he had attached the wings and engine to the chicken shed and had...flown the coop.
