And you thought testing the F-117 was a feat? In the days before building a full-scale 737 mock-up in your garage was possible, flight schools and even NASA relied on mechanical simulators to train pilots. Our friends at Oobject have collected 12 of the most advanced simulators of the day.

Be sure to also check out these impressive aircraft factories, some swanky airline cabins, and these POV plane landings.
