This clip is taken from one of the Warren Miller films. I don't remember which movie it was, and I don't remember anything else about the movie. All I remember was the crazy flying-squirrel-man. My biggest question is; how would you know for certain this would work? As I stood in the helicopter I would be thinking "hmmm if I'm right about this, it's going to be really fun. If I'm wrong, I'm dead."
Turn up the volume to hear the narration by Warren Miller. This guy is parachuting at only 15 feet above the ground at times!
