I certainly remember going to St Mawgan as an ATC Cadet on camp (probably mid 80's), it was definatley a huge vertical model model with a camera.
IIRC the cockpit was motion fitted with a static rear crew area.
I never got a look inside as there was a 'mission' on and they didn't want to disturb the crews by opening a door at xx000 feet and have a load of Cadets walking in!
I also seem to remember a large 'cotton wool' area for above cloud flying...or did I imagine that?
