Cornish Jack:
stalwarts such as M Plt Jack Huntingdon
Well he was a Flt Lt by the time I became one of his apprentices, CJ, but that didn't seem to affect his ability to produce a pithy Yorkshire expletive when the occasion called for it. If Ops Wing came up with some new super duper revolutionary way to dramatically increase the Hastings' Range/Endurance or whatever, they would nervously produce their paper for Jack's perusal. 5 minutes later he'd put it down and deliver his verdict; "f...ing stuff and f...ing nonsense"! The proposal would die there. On the other hand if you, by some miracle, produced a three pointer on the piano keys of a Tactical Landing from the RHS, Jack would take over with a "F...ing sow's ear lad, I have control". Bliss!
Oh as regards the OP my best instructor, other than Jack, was a Master Pilot on the JP. Don't know if that helps, but it did me!
