PN Cleator Moor, a real den of iniquity in west Cumbria.
I'm not a pilot, apart from around 500 hours solo gliding, but, I would have thought that the propensity to communicate was the main criteria for those selected as QFIs in the RAF. Firstly I would expect that anyone who would have passed their flying training to be competent in every respect. Perhaps then that "Creamies" were selected on the basis of their ability to both fly the aircraft and communicate the techniques to trainees. As I said, my flying as a pilot is limited, but I offer a small example. Shortly before I was sent solo in a Glider, my instructor told me to stop listening to him, and start telling him what I thought, and then carry out the action proposed, if I heard no objection. To that point I had sat, flown and hung on every word the instructor uttered. He gave me licence to think for myself, and the belief that I was capable. I was solo the same day, and will never forget his advice, he was a student at Cranwell at the time. I bet he heard that during his training.
