An airplane graveyard, sometimes known by the American term of aircraft boneyard, denotes a storage area for aircraft that are discarded after their years of service directly or lack of budget or because of the presence of obsolete technology.
The Davis-Monthan Air Force Base outside Tuscon, Ariz., is where old planes go to die. More than 4,000 military aircraft are parked on the base
Deserts, like those in the southwest of the United States, are good places for these cemeteries are, because of the size of the aircraft, very extensive.
Most aircraft are kept for storage or converted into scrap after provision for spare parts.The dry climate also reduces corrosion and potentially extends the shelf life.
