Like skydiving, space diving refers to the act of jumping from an aircraft or spacecraft in outer space and falling to Earth's atmosphere before parachuting to a landing. The Kármán line is the internationally accepted definition as to where space begins at 100 km (62 mi) above sea level. This definition is accepted by the Fédération Aéronautique Internationale (FAI), which is an international standard setting and record-keeping body for aeronautics and astronautics. The United States Air Force uses 50 mi (80 km) to award astronaut wings.
