Davis-Monthan Air Force Base in Tucson, Arizona.It’s where old planes go to die – a 2,600-acre patch of U.S. desert where several generations of military aircraft are stored in what has been dubbed ‘The Boneyard’.The facility is the size of 1,300 football pitches…
The desert is a perfect place to store the mass of steel, because low humidity and rainfall means very little rust occurs.Some planes are merely stored at the base between deployments, but for more than 80 per cent of the 4,200 aircraft that call it home, it is a cemetery of steel.
