This has to be the ultimate POW escape story and the ultimate aviation restoration/replication story. It has been nicely written and well-illustrated. The big surprise, beyond the actual flight, is that there are now several replicas of the Colditz Cock glider. This has to appeal strongly to aviation enthusiasts, replica builders, historians, and WWII enthusiasts, but the readership is likely to be much wider because its a great story of triumph against the odds and the indefatigability of the human spirit, very highly recommended.
