The Colditz Cock was a glider built by British prisoners of war for an escape attempt from Oflag IV-C (Colditz Castle) in Germany. BackgroundFollowing the execution of 50 prisoners who had taken part in the "Great Escape" from Stalag Luft III, the Allied High Command had discouraged escape attempts, though the plan to build a glider was encouraged in order to divert the energies of the prisoners from descending into boredom and tedium. The idea for the glider came from Lieutenant Tony Rolt. Rolt, who was not even an airman, had noticed the chapel roof line was completely obscured from German view. He realised that the roof would make a perfect launching point from which the glider could fly across the River Mulde, which was about 60 metres below. ConstructionThe team was headed by Bill Goldfinch and Jack Best. Goldfinch and Best were aided by their discovery in the prison library of "Aircraft Design", a two-volume work by C.H. Latimer-Needham which explained the necessary physics and engineering and included a detailed diagram of a wing section. The glider was assembled by Goldfinch and Best and 12 assistants known as "apostles", in the lower attic above the chapel. Future RAF Air commodore Geoffrey D. Stephenson assisted in the project.[3] The 60 ft long runway was to be constructed from tables and the glider was to be launched using a pulley system based on a falling metal bathtub full of concrete, using a gravity-assisted acceleration to 30 mph (50 km/h).[4] The officers who took part in the project built a false wall to hide the secret space in the attic where they slowly built the glider from stolen pieces of wood. Since the Germans were accustomed to looking down for tunnels, not up for secret workshops, the officers felt quite safe from detection. Nevertheless, they placed many lookouts and created an electric alarm system to warn the builders of approaching guards. Over thirty ribs had to be constructed (around a third being structural compression ribs), predominantly formed from bed slats, but also from every other piece of wood the POWs could surreptitiously obtain. The wing spars were constructed from floor boards. Control wires were made from electrical wiring in unused portions of the castle. A glider expert, Lorne Welch, was asked to review the stress diagrams and calculations made by Goldfinch. The glider constructed was a lightweight, two-seater, high wing, monoplane design. It had a Mooney style rudder and square elevators. The wingspan, tip to tip, was 32 ft (9.75 m), and it was 19 ft 9 in (6 m) from nose to tail. Prison sleeping bags of blue and white checked cotton were used to skin the glider, and German ration millet was boiled and used as a form of dope to seal the cloth pores.[5] The completed glider weighed 240 lb (109 kg).
The take-off was scheduled for the spring of 1945 during an air raid blackout but by then the Allied guns could be heard and the war's outcome was fairly certain. The British escape officer decided that the glider should be available for use in case the SS ordered the massacre of the prisoners as a way to get a message out to approaching American troops. The glider was approaching completion when the American Army liberated the camp on 16 April 1945. Although the Colditz Cock never flew in real life, the concept was fictionalized, depicting a successful flight and escape, in the 1971 TV film The Birdmen starring Doug McClure, Chuck Connors, René Auberjonois and Richard Basehart. One episode of the BBC TV series Colditz depicts the decision to build a glider as an escape attempt. It is also depicted in the final escape from Colditz Castle in the fictional story depicted in Prisoner of War, a video game released in 2002. The fate of the glider is not known, but the castle was in the zone controlled by the Soviets, who did not co-operate with its reclamation. The only evidence of its completion was a photograph, said to have been taken by an American soldier. However, Goldfinch had kept his drawings, which enabled a one-third scale model to be constructed. This was eventually launched from the castle roof in 1993. Modern replicaA flyable expanded polystyrene model of the glider was produced by the model kit manufacturer Airfix in its Skycraft range in the 1970s.[6] In 1999, a full-sized replica of the Colditz glider was commissioned by Channel 4 and was built by Southdown Aviation Ltd at Lasham Airfield. The glider was test flown successfully in 2000 by John Lee on its first attempt at RAF Odiham with Best, Goldfinch and about a dozen of the veterans who had worked on the original more than 55 years earlier proudly looking on. Jack Best died later that year. The replica is now housed at the Norfolk and Suffolk Aviation Museum at Flixton, Suffolk. The programme was shown in 2000 by Channel 4 in the UK as part of a 3-part documentary series called "Escape from Colditz". The Channel 4 material was edited to 60 minutes and shown in the US in 2001 as "Nazi Prison Escape" on the Nova television series. In March 2012, a radio-controlled, full-sized replica glider was built by Tony Hoskins' UK based glider maintenance/repair company South East Aircraft Services in the Chapel attic and was flown from Colditz for a Channel 4 documentary and launched it (unmanned) from the same roof as had been planned for the original. The radio-controlled replica made it safely across the river and landed in a meadow 180 metres below.[7] The documentary aired in North America on PBS under the title "Escape from Nazi Alcatraz" on 14 May 2014.[8] The glider built for this 2012 documentary now forms part of a new museum display in the Chapel Attic in Colditz castle, and opened to the public on the 70th Anniversary of the Liberation of Colditz in April 2015. The book Flight from Colditz by Tony Hoskins was published by Pen & Sword in the UK in April 2016. It tells not only the story of the original example built by the prisoners, but also details the other replicas built and on display.
