ULAS? Jerry Brown, Pete Lane, Owen O'Mahony, Andy Whitaker (CFI), Keith Skinner, Chris Booth, Keith Bomber, Malcolm Swinhoe plus others whose names I forget!
The Trident was obviously pretty quick - not many a/c can cruise at M0.87 these days! On occasion we would cruised the VC10 at M0.88 (indicated - actually only M0.86 true MN) before the fun detectors stopped it - it was part of a trainee co-pilot's trip back from Keflavik to Brize to fly as high and as fast as the ac could achieve, as it was probably the only time they'd ever see it done. But I was still required to take the old ladies to over M0.9 on full air tests
