SimTech67, the Brooklands museum would be ideal. They've managed to get their Concorde simulator working almost 100% now, although I think that it's fixed base. They also found a new technology way of including a very good visual system...
The old VC10 / VC10K simulator visual projection system was good when it was first installed, but became dimmer with time, no matter how new the projection tubes were. But still good enough to fly a visual circuit and to beat up the Stn Cdr's house at 100 ft!
Perhaps the K3 sim could be gifted to the Classic Air Force at St. Newquay Mawgan and the C1 to Brooklands?
Or is 'gifting' anathema to MoD beancounters?
