Great stuff.
Rudel's book, Stuka Pilot, is well worth hunting down. The only book that I've ever read in one go. I borrowed it from the local library, just on the off-chance that it might be interesting - and was up until four in the morning to finish it. If it was fiction, it would be silly. I wrote to the English publisher and he sent me the last copy that he had in his garage at home. It's out on loan at the moment, but I must read it again. They do turn up regularly enough, though. There is also a photographic book about him by Gunther Just which contains some crazy pictures.
