There was a USAF Aggressor pilot the late 70's/early 80's who had apparently survived hitting the deck in his F5 having got the nose buried doing ACT in Germany. The story (as I was told it) was he had bottomed out in a valley but hit the up-slope. The aircraft broke up around him, the engines passed either side and he woke up still strapped in his seat with a few cuts and bruises plus a broken ankle. He then became teetotal and a born-again Church-goer, and who could blame him.
