Vehicle Simulator will allow most anything. From undersea to outerspace.
All aircraft, helicopters, hot air balloons, para gliders. etc.
Cars, trains, submarines, space craft with full reaction controls. etc.....
you can drive and land on other vehicles.
Weapons of all types.
It's quite an impressive platform.
And inexpensive.
I'm pretty sure that with some work you could put your museum directly into one of the existing 'DEM' scenery's. Not too difficult to do.
Then you could use all of the camera functions within the sim.
And eventually fly all of your craft. Once the vehicle cfg's and parts are applied.

There is a demo, limited in some of it's functions, but it would give you a good idea of what the program will do on your machine.
