Hangar

A hangar is a closed building structure to hold aircraft, spacecraft or military tanks 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").
