Given numerous test runs using adequate amounts of safety equipment, and given these tests were performed during the same weather conditions - you could pull such a trick off. I can't argue with facts given in video form that base their premise on the laws of physics the way most humans perceive them. However, you can't escape the fact that a person needs to come to a complete stop from something that looks to be faster than 20m/s in less than a few tenths of a second. A person being able to stand straight up on his own and then being shaken by friends after having experienced more than 100 G?

Physics reality check = maybe, given enough luck (but highly improbable, even Evil Knievel used landing ramps). Physiology reality check = nope.

EDIT: This is a bit more real:

100%-fake

Why he didn't wear a helmet cam? Why there are no 2 videos from different positions?
