Would You Fly A Wingsuit Through A Mountain?

I mean, really, is there a stunt insane enough not to try in a wingsuit? On second thoughts, don't answer that. Wingsuits scare the heck out of me, although there's no denying that they can make for some awesome video. Like, say… jumping through a hole in a mountain. Not that this is totally insane in any way. Thanks to Chris for sending this link in. Just watching this is enough to make my head spin; I'm glad that's not me in the suit.
