During WW II the castle at Colditz was used to house Prisoners of War (Oflag IVC) who had a history of attempted escape. A plan was thought up for two prisoners to escape by glider and the Colditz Cock was built in the roof of the castle using materials available to the prisoners. The camp was however liberated before the escape was attempted. In a reversal of the norm, the original never flew but this replica built using the original plans was flown for the Channel 4 TV Series, Escape from Colditz. The aircraft is displayed at the Norfolk and Suffolk Aviation Museum, on loan from the Imperial War Museum
