1. Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider.
2. Most modern hang gliders are made of an aluminum alloy or composite frame covered with synthetic sailcloth to form a wing.
3. Typically the pilot is in a harness suspended from the airframe, and controls the air craft by shifting body weight in opposition to a control frame.
4. Hang gliding is usually achieved by launching into the air from a cliff or hill.
5. By the early 1970s the sport had spread throughout the United States and into Europe.
6. Like all other engineless aircraft, hang gliders use gravity as the source of propulsion , so they are always sinking downward, just as a skier goes downhill.
7. Hang gliders are controlled by shifting the pilot's weight with respect of the glider.
8. To do hand gliding instruction has been standardized and students learn from certified instructors using a thorough gradual training program.
9. While flying does not require great strength long duration flights in turbulent conditions require a moderate degree of upper body endurance.
