One of the most extreme types of Adventure Sport is the Paragliding. It is a recreational and a very competitive form of adventure sport. The pilot sits in the equipment which is suspended below with a fabric wing comprising a large number of interconnected baffled cells. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside. Despite not having an engine, a Para glider’s flight can last for many hours and can travel hundreds of kilometers. By skillful exploitation of sources of lift, the pilot may gain height, often climbing to altitudes of a few thousand meters.
