Oh, and one story of John was, as an Ops Officer at Finningley (1976?), a certain WW2 legless Fighter 'Ace' had rung up wanting to land at Finningley mid way through the BoB Display. I was priviliged to listen, (admittedly), to a one sided conversation over the phone, of a Master Navigator telling a (Retd) Group Captain to "Bugger Off". Diplomatically of course.
