When I attended an AAC seminar in BAOR back in the sixties the then Commander, 1 Br Corps addressed the seminar and was presented with 'honorary' pilots wings which he wore for the remainder of his military life.
Many of us felt this was altogether wrong as he never attended a pilots course, I still wonder if it was 'correct' and allowed?
Perhaps because he had been appointed Colonel Commandant of the AAC. And if I remember correctly he was given an abbreviated pilot's course so could handle an aircraft though not fly operationally.
And similar to several pilots, and at least one engineer, being presented with and wearing RAF Regt 'mudguards' after being appointed as Commandant General of the RAF Regt.
