I just watched it for the umpteenth time. Is he even wearing a belt? The pic's a bit fuzzy but I thought the Schweizers had four point harnesses and I can't see him wearing one. It just makes it all the more unbelievable that he wasn't chopped in half by the blades.
(for anyone who can't download the vid, after dropping from a VERY high, spinning sort-of-hover he smashes, tailrotor first, into the ground before the machine thrashes itself to bits on the floor, then numbnuts himself is seen in a bemused state surveying his work)
