Well, in its latter days before the grunts took the place over, RAF Abindon saw a MiG 21 arrive! I believe it was being donated to the UK by its previous owners to celebrate the fall of the Wall.
The thing landed and then taxiied at a fair old clip round the taxiway - with the pilot waving enthusiastically to everyone.
I'd heard it was intended to fly again in civil hands - but the good old CAA decided it was 'too complex'?
