Davis-Monthan is the largest of the "open air" storage facilities of the United States. This is where something like 80% of the US's WWII aircraft went, and amazingly there are still a few there, sixty years on. What potentially will be the second flyable B-29 in the world was pulled out of there just two years ago.

Considering how valuable WWII aircraft are today, and how enormous Chino Lake, D-M, and other places like them are, I often wonder if it wouldn't be worth it to purchase recon sattelite time to see just how many, if any, warbirds still exist there today. Kind of weird to think that a machine that defended the world from Nazism would still just be sitting there, out in the sand, day after day for six decades.
