Hangar

A hangar is a closed structure to hold aircraft or spacecraft in protective storage. Most hangars are built of metal, but other materials such as wood and concrete are also used. The word hangar comes from Middle French hanghart ("enclosure near a house"), of Germanic origin, from Frankish *haimgard ("home-enclosure", "fence around a group of houses"), from *haim ("home, village, hamlet") + gard ("yard").

Hangars are used for: protection from weather, protection from direct sunlight, maintenance, repair, manufacture, assembly and storage of aircraft on airfields, aircraft carriers and ships.
