My husband and I drove northwest of the city to do some exploring. I wanted to check out Marana Regional Airport and get a feel for the landscape out in that direction.
While driving around we stumbled across the remains of a Boeing 747-300 situated not too far from Pinal Air Park, where many no longer airliners are landed in the desert. This B747 was a mile or two away from the boneyard.
A quick Google search revealed the 747 was purchased to become a retail establishment. I found this article online with more information: Not quite a sky mall: Tucson inventor setting up shop in old airliner.
I look forward to doing more exploring out in that direction, both from the ground and the air.
