Blacksheep,
I can't recall the aircraft number but at Akrotiri we were taxiing past the sooty area near the tower, well away from the Bomber Dispersal, as we saw the nose wheel come off the ground and the luckless chief throwing himself onto the towing arm.
He had been faced with a stark choice, race for the bowser and stop the refuelling or jump on the tow arm. As the aircraft was already tipping he chose the tow arm.
He was, IIRC, on his todd and the inevitable happened. I don't remember any great fuss so maybe it was only a gentle touch. Be about 71-72.
