I have to agree, for me one of the things that differentiates bushcraft and survival is the circumstances of the situation, this guy's in very great danger and has to survive it, in this case he crawled out, that's so tough, he survived the situation, I think in circumstances like this bushcraft helps people survive, it could have helped him identify berry and fungi, or know where to shelter for the night etc but he's well and truly into a survival situation and not a self imposed bushcraft situation, don't et me wrong there's some huge overlap but for me it's the circumstances that dictate the definition.
Thanks for posting it up, things like this always get one thinking...
