I have no information regarding a simulator on the base, but the museum does have so-called simulators.
There is one of the "mall" type sims that you climb into with 6-8 other folks and ride a darkened roller coaster......
Then there is the area of the museum where groups can "fly" with simulated atc and even do some combat. This set up involves multiple cockpits networked and using a customized version of MS Flight Sim. The controller is an actual USAF veteran controller.
The museum is well worth a trip. You will see a P51 and P40. And a few larger airframes such as a B29, C46, C47, B25, Ventura.
The museum has the cockpit of a Waco glider imbedded in a hedgerow. There is an A26 sitting outside on static display.
I think you will enjoy the visit.
Be sure to take a look at the SR71 and D21 airframes. ICHIBAN is GORGEOUS!
I make a trip to the museum every 3-4 months, just as an escape from the everyday life.....
Enjoy your visit!
