John was my Ops Officer at 6FTS Finningley (mid 70's). He taught me a great deal, which stood me in good stead. An amazing guy. However, he was ruthless on a golf course, John took no prisoners!. For his patience with a rookie, for his humour with his colleagues and the coughing fit he had on the 18th at Bawtry in a needle game (me putting). Bless you, John. Gone, but not forgotten.
