Polyesters are usually derived from ethylene glycol and terephthalic acid, or similar chemicals. The most common polyester for use in making hang gliders is polyethylene terephthalate, known by the trade name Dacron. The frame of a hang glider, also known as the airframe, is made from an alloy...
Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow over the wing. In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as ...

In a sense, wingsuit flying is a cross between skydiving andhang gliding. Like both of these activities, wingsuit flying requires the flyer to either jump out of an aircraft or off a precipice to achieve a high enough altitude. While hang gliders can coast in for a safe landing, wingsuit...
On the horizontal tail wing, these flaps are called elevators as they enable the plane to go up and down through the air. The flaps change the horizontal stabilizer's angle of attack, and the resulting lift either raises the rear of the aircraft (pointing the nose down) or lowers it (po...
aSTARTING OUT WITH KITES AND GLIDERS[translate] aNext, the Wrights built a wooden glider. In 1901, they experimented on the larger sand dunes at Kill Devil Hills. The glider had arched wings, a design that made the glider more stable. It also had hand controls that worked a flap on the...
Modern airplanes are phenomenal pieces of technology, but they're not worth much if you don't have somebody who can fly them. The skills and expertise of veteran pilots are crucial to airline organizations, as well as to getting you where you need to go. The flight-attendant crew is ...
9. Hang Mirrors on the Wall Wall mirrors are an excellent way to make low ceilings feel higher. Because mirrors reflect light, they're often used to make a space feel larger and brighter – and the same idea applies to height! Place the wall mirrors higher than...
In 1974 Peter Brock, who was manufacturing hang gliders in California, gave Rogallo his first factory-made glider, and Rogallo made his first true hang-glider flight, floating over a California beach in the state where he had been born 62 years earlier. “I think that at that moment he ...
