Retired A-10 Thunderbolt IIs. Davis-Monthan AFB, Arizona [417x755]

Retired A-10 Thunderbolt IIs sit at the 309th Aerospace Maintenance and Regeneration Group’s Aircraft and Missile Storage and Maintenance Facility on Davis-Monthan AFB, Ariz. Arizona’s low humidity, infrequent rainfall, alkaline soil and high altitude of 2,550 feet reduce rust and corrosion. The hard soil makes it possible to move aircraft around without having to pave the storage areas. (U.S. Air Force photo by Staff Sgt. Perry Aston)
