Hang gliding in the context of "Air travel"

A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch.

There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders.

Lift is a meteorological phenomenon used as an energy source by soaring aircraft and soaring birds. The most common human application of lift is in sport and recreation. The three air sports that use soaring flight are: gliding, hang gliding and paragliding.

Energy can be gained by using rising air from four sources:

The term "air sports" covers a range of aerial activities, including air racing, aerobatics, aeromodelling, hang gliding, human-powered aircraft, parachuting, paragliding, soaring, and skydiving.

Devil's Dyke is a 100-metre (330 ft) deep V-shaped dry valley on the South Downs in Sussex in southern England, 5 miles (8.0 km) north-west of Brighton. It is managed by the National Trust, and is also part of the Beeding Hill to Newtimber Hill Site of Special Scientific Interest. Devil's Dyke was a major local tourist attraction in the late 19th and early 20th centuries. It is now a popular viewpoint and site for walking, model aircraft flying and hang gliding. The South Downs Way passes the site.

A foot-launched powered hang glider (FLPHG), also called powered harness, nanolight, or hangmotor, is a powered hang glider harness with a motor and propeller often in pusher configuration, although some can be found in tractor configuration. An ordinary hang glider is used for its wing and control frame, and the pilot can foot-launch from a hill or from flat ground, needing a length of about a football field to get airborne, or much less if there is an oncoming breeze and no obstacles.
