In 1943 three men came up with an ingenious plan to escape from the seemingly escape-proof Stalag Luft III prison camp in Germany. In this episode of the Futility Closet podcast we'll learn about their clever deception, which made them briefly famous around the world.

We'll also hear about the chaotic annual tradition of Moving Day in several North American cities and puzzle over how a severely injured hiker beats his wife back to their RV.

Oliver Philpot, Stolen Journey, 1952.

Here's the movie:

It became the third most popular film at the British box office in 1950. The book's success led Williams to write The Tunnel, a prequel that described his and Michael Codner's earlier escape from the Oflag XXI-B camp in Poland.
