Any aircraft that is heavier than air, can sustain flight due to its design, yet does not use an engine can be classified as a glider. There are three major categories of glider: sailplanes, paragliders and hang gliders.

Sugar gliders are native to Australia and New Guinea. They live in forested areas, and they are named for their ability to leap and glide from tree to tree. Their gliding ability is derived from a flap of skin that conne...

Gliders utilize a combination of gravity and air currents to stay in the air. Lift, drag and thrust are also important to the gilder's ability to fly smoothly for hours after a motorized plane has towed and released them...

Airplanes fly because the design of the wings produces lift that counterbalances the weight of the aircraft. Air flows more rapidly over the top of the wing than underneath it, which reduces the air pressure above the su...
