Hang gliders rely on currents of warm air called thermals - to lift them high into the atmosphere. Knowing the type of weather in the area they want to fly - enables them to plan a route to make the most of the available updrafts.
Low pressure usually brings stormy weather. The clouds hang over and area for a period of time and then the rain and storm begins.
The hazy clouds that hang over some cities is called smog

S hooks are very useful when one is trying to hang things. One could hang potted plants or pots/pans with S hooks. In the past, S hooks could be used to hang different sized cooking pots above the fire.

Videos of hang gliders soaring through the air are available directly from YouTube. Users upload hundreds of hang gliding videos to the site on a regular basis.
Internal forces that act on hang gliders: Shear Compression Tension External forces that act on hang gliders: tell me, because I don't know! I'm the one asking!
Hand gliders use to be used in space for transportation. )Before used on earth)

Otto Lilienthal (1848-1896) was one of the first men to fly. He designed, built, and flew many different designs of gliders. His gliders were designed to be controlled by shifting his weight, just like modern hang gliders. He died flying one of his powered gliders. The Wright brothers were inspired by his bi-plane designs.
It depends on the glider. Some are smaller than others.
None the wind keeps the glider in the air
A2. When they fail, their failure is catastrophic. Survival is quite in doubt.
