Back in 1972 I was an RAF Police Dog Handler at RAF Waddington and I with others guarded these wonderful A/C. I remember on one occasion when these mighty A/C at the end of an exercise simulating QRA release, we had taken refuge behind the fixed electrical boxes as the A/C turned on full power for protection from the blast. However a dog handler named Phil Anderson stood up to see them take off when he did the blast of the A/C engines blew him and he’s dog off their feet. I still see it to this day, both dog and handler flying through the air for some 10 to 20 feet. Both were a bit shaken but apart from the handler who was very embarrassed, both were ok.
