'.. the other was a Brian ? who appeared to suffer spine/back problems and, at the time, was hopeful CME would prescribe some kind of back support for him.'
I think you will find that the Gentleman in question was a chap called Flt Lt Mike Blee, ex Nimrod driver and a really nice bloke. I was fortunate enough to be the airframe man on his aircraft (B), so was able to beg some great flying with him on SCT days. Unfortunately he died in a mid air collision whist doing air experience flying for ATC cadets. I believe the cadet passenger also died in the accident which involved a glider. Hope that helps.
