Hand gliders do not exist - just bad grammar for hang glider.
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.
NASA made the first hang gliders back in the 70's as part of their mars experiments.

dealter kites are the olny ones
Actually Gliders were invented during the time of War. Germans wanted to spy on other countries. So they built gliders.
None the wind keeps the glider in the air
It depends on the glider. Some are smaller than others.
Hang gliders are not used in space. They rely on Earth's atmosphere for lift and are designed to be used in the planet's atmosphere. In space, spacecraft use thrusters and other propulsion systems for movement and control.
A2. When they fail, their failure is catastrophic. Survival is quite in doubt.
