Description
A cowardly space pilot flees a battle until his spaceship runs out of power and he crashes into a bog on an Earth-like planet. He finds himself among humanoids in an era similar to Earth's 1492 Spain as a sailor is attempting to prove the planet round with a voyage around the globe. The space pilot thinks this is a sure bet to gain fame and fortune so he arranges to exchange places with the sailor and head out to sea. Unfortunately for him, the planet he has crash landed upon does indeed turn out to be flat.
