what do you do to land?
The pilot will 'land out' - choose a location where he can land safely without damaging the glider, the pilot, or property such as crops or livestock.
Gliding
If lift is not found during a cross-country flight, for example because of deteriorating weather, the pilot must choose a location to "land out". Although inconvenient and often mistaken for "emergency landings", landing out (or "outlanding") is a routine event in cross-country gliding. The pilot has to choose a location where he can land safely without damaging the glider, the pilot, or property such as crops or livestock. The glider and the pilot(s) can then be retrieved by road from the outlanding location using a purpose-built trailer. In some instances, a tow-plane can be summoned to re-launch the aircraft.
how long do gliders stay in the air They can stay airborne for several hours. what is gliding? It is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. who created the first glider? The Germans when? In  the 1920s and 1930s how do they fly? Through air that is ascending as fast or faster than the glider itself is descending, thus gaining potential energy. what's the fastest they can go? UNANSWERABLE so you mean they use lift to fly? Yes, ridge lift, wave lift etc. how are they launched? Different methods, namely aerotowing, winch launching, bungee launch etc. what's the maximum distance they have flown? Up to 1,000 km
