Outside of your parachute not opening, this has got to be one of the scariest things that could happen to a skydiver.  For some reason this plane takes a nose dive after the first jumper releases and the rest of the crew are left pinned inside the plane as it plummets toward the ground.  Apparently the pilot was wedged in and barley got out in time (he jumped at 1000 feet).  Talk about a pants shitting experience.
