A reader corrects me: “Here in Tucson, AZ, the USAF maintains a storage

area (called AMARC) of functional but out of use aircraft. The dry desert

climate and alkali soils make this the ideal location for equipment to be

preserved though stored outdoors. Nearly 5,000 aircraft are currently

present, mostly still quite advanced designs. That is the 2nd largetest Air

Force in the World. So the US has 1,2,3, AND 4.”
