Escape from Colditz

British officers dreamt up an audacious plan to escape from the high-security Nazi prison using a glider made from bed sheets and floorboards. They hoped to fly to freedom from the roof of the castle, but the conflict ended before they could put their plan into action. Here, Cambridge University's Hugh Hunt, whose uncle was a prisoner in Colditz, leads a team of aeronautical engineers and carpenters as they rebuild the glider in the attic where the original was constructed.
