Haven't read all the responses in this thread but the RAF had a 'treatment' programme for pilots with flying phobias - at least in the early 70s. My understanding was that once a pilot 'fessed up - presumably at medical time, they were assessed by a clinical psychologist. After that they would attend CFS Rissy where the Flying Doc (Gordon Smith at the time) would gradually expose them to the aspect of flight that caused the problem. This was all done at Standards Flt (not exam wing) where there was a constant through-put of refresher QFI training going on. The two JP standards QFIs flew with them also as I recall. It wasn't talked about much so I suppose most waterfront QFIs and students assumed they were there for refresher training. I spoke to a few that were from F4, Lighting & Herc I think. Problems ranged from flying over water to high altitude. Gordon died in a Meteor accident a few years later - I don't think he was replaced at Rissy so maybe the programme was canned?
