Thanks for the info. My mum is still going and she'll give me authority.
After he got his MBE he moved onto the flight simulator. Again I don't know what he did there - as a pilot grounded on medical grounds and no experience of flying the Vulcan for real could he still work as a Vulcan instructor? I know he knew how to fly it - on a Sunday afternoon we'd jump in the car, drive up to the simulator block, park in his parking space outside and he and I would spend the afternoon flying the Vulcan simulator.
I was only 12 so it was an experience for me.
