These guys don't appear to have been morons. I think what AlpineK is saying is that your vast majority of tourons who heli-ski out of vail, whistler, what-have-you are probably morons, and I'd say, by and large, yes. That's why they hire guides to "protect" them. Juan is right as well, however; there are plently of very good skiers and climbers who can afford to or bum rides in helicopters as well.
It's funny that just a few weeks after everybody lambasted everybody else for jumping to conclusions regarding avy accidents, everybody wants to do it again. It sucks ass no matter what happened. Maybe they did everything right, maybe they fucked up. maybe it was a combinations of both. In any event, hindsight is 20/20.
