Wing suit flight is divided into two categories: powered wing suit flight and unpowered wing suit flight. Among them, no power wing suit flight, international known as flying squirrel suit gliding. Refers to the athletes wearing have wings flying equipment, clothing and parachute athletes from aircraft, balloons, escarpment, high-rise buildings, such as high jump down, flight to use body movements to control the glide direction, with a body without power air movement, reached the security limit height, athletes will open the parachute a smooth landing. When unpowered wingsuit flight enters the ideal flight state, it can usually fly at about 200 km/h and glide ratio of wingsuit flight is about 3:1, that is, advance about three meters for every meter of descent. Challenger for low wing outfit flight altitude co., LTD., is used to adjust the position and open the parachute time hasty, flight of danger and difficulty greatly, by 2012, fewer than 600 people around the world dare to try this adventure, so the wing outfit flight also is widely considered to be the craziest extreme sports in the world, is the limit of extreme sports.
