Unpowered flight information

Unpowered flight is the ability to stay airborne for a period of time without using any power source. There are several types of unpowered flight. Some...

Unpowered aircraft can remain airborne for a significant period of time without onboard propulsion. They can be classified as gliders, lighter-than-air...
