Hello; 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. During the height of the pandemic, when air travel was near zero, all the major airlines sent some of their unused aircraft down to Tucson for the same preservation reasons the video talks about. Very interesting! As a trucker, I travel down to Tucson a few times each month, and I'm always looking around as I get nearer to the boneyard, to catch a glimpse of any of those beautiful war birds of the USA!
