Gentlemen, as a standard "baldrick" I doubt that my input will carry any weight, I offer simply this. Ken Hayr was one I certainly looked up to during my time in the RAF, and he always seemed to me to offer a fair judgement of matters of concern. Unfortunately, many more senior personnel have stamped their own desires over his balanced opinion. I suspect that this thread is already diverting to a willy war about who was the best "leader of men" surely the OP had the intention of looking at why people, of whatever trade, left our service, and, the reaction of the management to their departure. I, like many, would always suspect that the first to leave are our best assets, and no, I'm not one of them, I was discharged due to being broken in a flying incident. Is the OPs intent to discuss who was the best senior officer you knew ? I doubt it.
