Did you have gear to dig him out though? That door swings both ways. Getting buried and having to use your gear is the very last resort thing after you have fucked up big time everywhere else. A very high percentage of the time, you don't survive getting buried. Jim Jack one of the three in the Tunnel Creek avalanche was reported being folded in half the wrong direction. DOA. He was found and dug out in under 15 minutes, but as the saying goes, when your are folded in half backwards, you're fucked.
It's worth taking your time to do this aspect of riding right. A lot of fun, but there is little room for error.
