On the confidentiallity bitand postings being changed, I know a V-force copilot who was told he would lose his PV if he married a Yugoslav. He did and he was posted to Canberras, 360 IIRC.
Then there was the Air Marshal who, had his posting been changed or stopped would have signalled that he had failed his PV. Instead of that 'embarassment' he was outed by the Sun or NOWS in the toilets at Shepherd's Bush. At the same time we were told that a wg cdr had made a confession to the confessors and therefore been given a clean bill of health.
So much for confidentiality. There weren't that many wg cdrs in the frame. Then a V-force nav rad was posted we knew why, too many sherbets, too often.
