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 a certified 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 flown the coop.
