I, like Beags (beat you by 8 Beags) had many years of Tanker time and was fortunate to survive unscathed in spite of near misses thanks to overenthusiastic young and not so young jet jockeys. The tricky situations were usually over so quickly that any reaction would have been too late and possibly made it worse, though Ben There got it right. Where control restriction of any sort is awkward is in disparity between types in formation so that rates of roll can not be matched. Let us not forget that a tanker is an aeroplane with a full envelope to fly from t/o to landing and the fly by wire protection is relevant throughout. I have had more scary moments in the circuit than whilst tanking.
