This photo was taken of one of the many Tucson scrapyards, who have the job of destroying obsolete military planes. I think the one in the photo is a C17 Globemaster. Just up the road from where this was taken is the Pima Air and Space Museum who have an astonishing collection of aircraft, it seems that when AMARC choose to scrap planes, they keep one example for themselves and give one to the musuem.
