RAF What-a-shame, circa 1968:-
Hedley Molland, Treble One's Lightning Display pilot, and a damn good one, breaks off from a four-ship incoming formation and proceeds to beat up Lakenheath (USAF). Zero feet, Mach 0.99, rotation up into the clouds, without, apparently, announcing his presence or intent.
Big ructions from on high, on the lines of "Who the **** was it, then?" No one owns up.
Some time later, one USAF fighter booms across the tarmac at Wattisham, zero feet, Mach 0.99. Radio transmission goes something like:-
(USA accent) "Hey, Hedley, whaddya think of that?"
Great times.
