Sometimes stuff like this makes me think that it's not a good idea to do back flips on large pieces of machinery.
It's too bad the guy died, but I watched that clip and that seems like the dumbest and most boring sport on earth. You jump a snowmobile off a ramp and then stand on your seat. Big deal. You jump a ramp and then spin on your seat. Was anybody still watching when he tried the flip?
