63000TZ You triggered a memory there from the late '60s - early 70's. VC10 doing circuits on 05 (as was) with B707 doing ILS and go-around on 23. Timed to perfection the result was a VC10 climbing over the 707 rolling opposite direction. Both BOAC and both, apparently, quite happy. Unlike the boss who came hurtling up the stairs demanding to know "WTF?" Those were the days.
