My father instructed as a Sgt Pilot at Middleton St George in the early fifties and in later life, told me he had 'chopped' guys for their own longevity. When it came to my turn to 'chop' people, his advice was if it was justified to just step forward and do it. I recall one chap who came over to our table and the Sailors (Mariners?) restaurant in HKG and told me it was the best thing that ever happened to him and I took a big load off his shoulders.
