Stalag Luft 14

Stalag Luft 14 was a World War II prisoner of war camp in Germany. The Eleventh Doctor led a group of prisoners in an escape from it. However, the Doctor's tunnelling expertise was a bit off as the tunnel led directly into the Commandant's office.

In 2011, Amy Pond and Rory Williams read about this incident in the book Myths and Historical Impossibilities. (TV: The Impossible Astronaut)
