"The Boneyard, Tucson, Arizona Adjacent to the PIMA Aerospace Museum, outside Tucson Arizona, is the 309th Aerospace Maintenance and Regeneration Group, based at Davis-Monthan Air Force Base. Here at any time, around 4000 planes, valued at an estimated $33 billion, wait to be sliced, shredded and recycled for parts, earning it the name The Boneyard. Visitors tour the site by bus and are greeted by the magnificent sight of a sea of tail fins, eviscerated engines and bisected fuselages stretching from horizon to horizon. The planes here date from the Vietnam era or newer and many of them represent models still in active service, like the venerable C-130 Hercules transporter, which has seen around 60 years of duty. Most of the planes have seen surgery of some sort, either at the sharp end of the giant guillotine that slices them cleanly into sections, or have had specific components removed, their wounds covered in what look like white plastic bandages." - Winckel
