In a similar vein Channel 4 screened an interesting program in 2008 entitled Who downed Douglas Bader in which air historian Andy Saunders located & dug up two downed spitfires in northern france - neither of which turned out to be Bader's. Andy Saunders subsequently wrote a book about which I would like to read
- Bader’s Last Fight (Grub Street 2007). As per usual the answer lay in the meticulous record keeping of the germans rather than in digging up planes, but it was a fascinating and moving piece of archeology. You can certainly download it if you're not as scared as I am of internet download sites.
