OK - Simulator 'war story'.

I was working on achieving the provision of a Visual ATC Simulator for Local Control Training at the RAF Central Air Traffic School. CGI and all that good stuff. Techie colleague and I were exploring what everyone else was doing, which involved everything from the French Mil ATC school with aircraft on sticks mounted on a model railway to the Australians' CGI system (dammit, we had to go and see that).

Anywaaaay … one day we went to Farnborough (IIRC) where they had some super cockpit CGI test rigs. Cracking. Basic ockpit, brilliant imagery … but no motion. Oh, so here come the disturbed eustachian tubes, when the visual inputs didn't correlate to the motion that wasn't there. My colleague lasted about 4 minutes before leaving the Lab to be air-sick!
