Damn it, I was in the ATC in the 70's, never got near that Beagle. It sure looks like a nice aeroplane! It seems I missed out twice as I never got near the AEF airline flights either.
I did manage to get a little gliding in at Kenley in Kirby cadet mk IIIs and Sedbergs. Plus a couple of Chipmunk flights at RAF Abingdon and RAF Benson. Oh well..
