Skydiver Is Knocked Out and Gets Rescued Mid-Descent

This happened a few years ago, but a skydiver has recently posted a video of himself getting knocked unconscious from a collision in mid air. One sky diver with a helmet cam sees the whole thing and jumps into action reaching the unconscious guy and pulling his shoot for him. The craziest thing about the story is that the guy actually landed in their drop zone safely while knocked out.
