yep that was just a bit to slow there fella. But im pretty sure letting off the throttle when he did is what he was supposed to do. on a incline like that if you were gunning it you would probably just flip.
Good point, that would have been a winning move. But in that brief window he could have jumped, he was still too busy realizing the enormity of his mistake to make a bailout decision. So he rides that bird right into the cliff.
