Orderly Sgt at Coningsby, early 70s, little Irish guy, initials EC. Come 1700, time to lower flag, he mixes up and accidentally lowers small pennant at the top of the flag pole instead of the main Flag. Reputedly the SWO, who just happened to be nearby when the whistle went and snapped to attention, had a sense of humour failure and intervened in no uncertain terms.
