Hang Gliding is an air sport activity in which a pilot flies light weighted wings made of tough fabric over a strong frame. This sport developed in the late 1960s. It takes about 15 to 20 minutes to set up and prepare to launch. Hang gliders are launched when the pilot runs from a hilltop or peak in the wind. The pilot controls the aircraft by shifting body weight in opposition to a control frame. Hang gliding is a very expensive sport.
