NOVA (1974)

Season 41: Episode 21

Colditz Castle, a notorious prisoner of war camp in Nazi Germany, was supposed to be escape-proof. But in the dark days at the end of World War II, a group of British officers dreamt up the ultimate escape plan: in a secret attic workshop, they constructed a two-man glider out of bed sheets and floorboards. Their plan was to fly to freedom from the roof of the castle, but the war ended before they could put it to the test. Now a crack team of aero engineers and carpenters rebuild the glider in the same attic using the same materials, and they’ll do something the prisoners never got a chance to try: use a bathtub full of concrete to catapult the glider off the roof of the castle. As the hair-raising launch 90 feet up draws near, the program explores the Colditz legend and exposes the secrets of other ingenious and audacious escapes. Then, after a 70-year wait, the team finally finds out if the legendary glider plan would have succeeded.
