Banzai Skydiving is a form of skydiving in which the skydiver throws their parachute out the airplane door, waits for a time and then jumps after it. Obviously, to be successful, the skydiver must catch up to the parachute, attach themselves then descend to the landing zone. It's not really a sport, and is not to be encouraged.
In some cases the skydiver wears a special harness that attaches to a cord extending from the parachute, which ensures the skydiver can safely recover the parachute. Otherwise, other skydivers are there to assist in either attaching to the diver or attaching a parachute. In 2006, skydiver Luke Aikins jumped from 25000 feet without a parachute, and successfully landed in a large net.
