The Summer of '76 was, as those old enough might recall, pretty damn hot.
Having finished my Hunter course, I was asked to stand in as RSO at Pembrey for a day whilst the real one was away on leave. As we drove to the range hut, I saw some very mangled 230 tanks sitting in a storage area. "What happened there?", I asked. I was told that some refresher Wg Cdr on 79 Sqn had made a monumental switch pigs, selected the wrong pylons and pickled off near on 460 gallons of HM's finest Avtur across the range. Following which, our hero asked if he could continue, but was told to RTB asap! It would only have needed the smallest spark to set the whole lot and the tinder dry range aflame!
I understand that a refresher triggernometry brief from one of 79's QWIs followed soon after the gallant Wg Cdr landed...
