What is a hang glider?
A hang glider is a foot-launched weight shift aircraft. The pilot is suspended in a harness below a wing that consists of a dacron or mylar sail stretched across an aluminium frame around 8m across and 4m deep. The wings aerofoil shape, necessary for the generation of lift, is maintained by a series of aluminium or fibreglass battens inserted into pockets in the sail. Most hang gliders are flown with the pilot lying down (Prone). The pilot uses the triangular control frame to shift his weight, and in that way control the speed and direction of travel of the hang glider.
