Pima Air and Space Museum isn't part of the boneyard. It's a private enterprise that has old, aircraft that for the most part will never fly again. Most of the aircraft in the Air Force boneyard, are able to be restored within weeks to flying condition. You can get a tour of the boneyard through the museum. It's in a bus though and you can't go outside, so no real good picture opportunities.
More info at the museum website.
Thanks for the info Ishtar...I had always thought AMARG was off limits to the public since it was a military facility. I will have to get down to Arizona and check this out!
Does anyone know if there are similar tours at boneyards for commercial aircraft such as Marana, Mojave, or Victorville?
Also on the Discovery show
Mythbusters they went to a boneyard for light aircraft to purchase parts for some of their experiments. Anyone know the location?
