Full Bune Psychos.

Here is a 60 Minutes story about these guys who take hours to climb these mountains and once they get to the top, they put on these crazy wingsuit things and jump off..the guy said they fly down the mountain at about 140-150 mph, which is NUTS..it would probably be pretty fucking awesome, but if you muffed up, you would have literally no chance at living to tell about it..unreal shit, give it a watch.
