Coming in rather late on this thread, but rember being at LL as a lowly ATCA when a Concorde landed on 23. Didn't touch down anywhere near the normal point and eveyone was convinced he was going off at the end. The pilot held the nose up and used aerodynamic braking and ended up stopping in plenty of time, but pretty convinced CONC ops on 23 were banned after that.
I alway found 23 the be a bit nervewracking driving on the airfield, we were supposed to have a briefing on runways in use etc before venturing out but generally just winged it - approaching to cross 23 in Pixie there was always doubt in your mind as the whether it was a taxiway or runway that day! Definate loss of face to ask on the radio, so just hoped that the wig-wags at you intersection hadn't failed, had a good look down the approach and drove over!
Off back to work in Fraggle Radar!
