An airplane graveyard, sometimes better known by the American term of aircraft boneyard, designates a storage area for aircraft that are discarded after their years of service or directly fault of budget or because of the presence of obsolete technology. Most aircraft are kept for storage or converted into scrap after provision for spare parts. Deserts, like those in southwestern United States, are good places for these cemeteries are, because of the size of the aircraft, very extensive. The dry climate also reduces corrosion and potentially extends the shelf life.
