The human-size flying squirrel in this video is named Jeb Corliss. He's a professional BASE jumper and a wing-suit pilot. You may remember him as one of the people who BASE jumped into the Super Bowl XXXVIII pregame show. You may not. Corliss has been permanently banned from the Empire State Building for trying to jump off it. According to his Facebook page, his interests are "Sharks, BASE and Fear..." He also likes to grind the crack.
