How the world's largest airplane boneyard stores and regenerates 3,100 retired aircraft

The 309th Aerospace Maintenance and Regeneration Group stores thousands of retired military, forest service, and NASA aircraft in the Arizona desert. The massive collection of F-16s, C-5s, B-52s, A-4 Skyhawks, and others would be the world's second largest air force. But the planes don't just come here to die. Parts are reclaimed and entire planes are regenerated so they can go back into service.
