While in Tucson we visited the Pima Air & Space Museum which is located at the Tucson Aircraft Boneyard. For those who may not be familiar with the boneyard, this is where all the old aircraft go to die. You may have seen aerial photos of the thousands and thousands of old aircraft parked out in the desert for the rest of their lives or be used for replacement parts as possible. I have always wanted to visit here and so we did on this trip.
