self sustaining sailplane
The independent variable of a glider, if it is an air glider, would be the thermal updrafts available at any flight. Without effective thermals, it makes it difficult for a glider to maintain lift and develop elevation for sustained glides.
Glider means a light aircraft that is designed to move without a motor or a person or another object that flies or moves without a motor. A glider can also refer to a small mammal called a sugar glider.

Otto Lilienthal was the German inventor that designed and built a glider that would carry a human in 1891. He died in 1896 at the age of 48 when the glider he was flying lost power and crashed.
Weight is the main factor in the flight of the glider. More weight means the glider does not fly great distances. If the weight is less it will travel more distance.
