Many years ago I was doing my ground tour as a P Staff chap at Training Command and I seem to remember something about Pteraphobia which, as I recall, was almost a taboo subject. It seems that it was considered infectious so, if anyone was afflicted they were very quickly hustled of in some secrecy and eased out of the force. Never actually came into contact with it personally but I was certainly briefed on the matter. This was at about the same time (not too long after WW2) as PN's AEO who I knew. What turned him was a close relative being killed (maybe a brother) in a V bomber crash. I believe he actually became a solicitor in the end
