Yes, I know it is not an Aircraft !!!
Mobile B-52G Flight Simulator USAF/SAC.
Doing some research for our new North American Museum of Flight Simulation, I ran into a couple of simulators that are quite unusual. Apparently SAC had those flight simulators running between their major bases during the cold war.
This one is a B-52G simulator and there was also a KC-135 simulator which apparently sits abandoned at the Elgin AFB. Would not mind to have that at the museum :-)).
