Escape from Nazi Alcatraz (2014)

Colditz Castle, a notorious prisoner of war camp in Nazi Germany, was supposed to be escape-proof. But at the end of World War II, a group of British officers dreamt up the ultimate escape plan: a two-man glider made out of bed sheets and floorboards. Now a crack team of engineers and carpenters rebuild the glider in the same attic using the same materials to find out if the legendary glider plan would have succeeded.
