Just watched a film about this guy (The One That Got Away) and i must say, wow, this guy was really determined. He was the only PoW to escape from allied captivity during the war (with the possible exception of baron Chuck von Norris) and it is actually amazing some of the lengths he went through.
I am certainly on the lookout for the book of his actions now, and just thought I'd bring this up with you guys in case your missing out on a bloody brilliant adventure story...
