Does a glider have drag?

In order for a glider to fly, it must generate lift to oppose its weight. The motion of a glider through the air also generates drag. In a powered aircraft, the thrust from the engine opposes drag, but a glider has no engine to generate thrust.

Can gliders fly at night?

Yes. But as rare as a 7 engined air liner. Actually every night there are thousands of motor gliders as they fly from cruise at0 feet into the TMA to deliver their passengers. How heavy is a glider? While the FAA defines a glider as a "heavier-than-air", it's not by much. The lighter weight is crucial to creating the most efficient flight possible. The weight of a glider directly impacts its performance. Gliders can range from an empty weight of 134 pounds, to a maximum weight of almost 2000 pounds, that's a ton!

Do gliders crash?

Four types of events make up the majority of glider accidents: loss of control in flight, collisions with the ground and in flight with obstacles, missed landings or take-offs and finally, mid-air collisions. They can also occur on an aerodrome, during flight near the ground and at relatively low speeds. What is an air glider? A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Gliders are principally used for the air sports of gliding, hang gliding and paragliding.

How do gliders land?

Landing a glider is much like landing a conventional plane, except there is usually a single small wheel located directly under the pilot. The pilot has to be able to reduce the amount of lift produced by the wings without changing the speed or attitude of the glider. He does this by deploying spoilers on each wing.
