A glider is a type of aircraft that can fly without using an engine. It works by being launched into the air and then gliding through the air, using air currents to stay up. Gliders are most commonly used for recreational activities such as soaring, flying long distances or for activities like hang gliding or paragliding. They are also used for military purposes, such as reconnaissance or surveillance. The word 'glider' should be used when talking about this specific type of aircraft.
