Aircraft boneyard

Boneyard facilities are generally located in deserts such as those in the southwestern United States, since the dry conditions reduce corrosion and the hard ground does not need to be paved.

[3][4][5] Some yards are privately owned and operated, others belong to the military including the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base in Tucson, Arizona.

The reconditioning process includes putting in new avionics, electronics, safety measures, testing, and painting.

The 309th Aerospace Maintenance and Regeneration Group in Tucson, the largest facility of its kind, is colloquially known as "The Boneyard".
