Y0u've gotta be pretty crazy to jump out of a helicopter.  You've gotta be even crazier to do it wearing a wingsuit.  You've gotta be outta your effin mind to use that wingsuit to fly through a mountain.  Check out the video.

Of course Red Bull has something to do with this, because Red Bull always has something to do with crazy ass sports.  This video was shot in China and features human glider Jeb Corliss.  I can't imagine how scary it would be jumping out of that helicopter, let alone flying through a cave.  If he would have been even slightly off in his judgment, Jeb would have been getting scraped off that mountain.
