I'm 100% with you BOAC..as usual..
..but yes... I'd prettymuch discounted the published LDA because these guys seemed to be flying at a steady height above the runway for quite a while.. with the TDZ disappearing fast behind them... and all the time with F30 (= un-necessarily fast) and a tailwind. Apologies if my terminology was confusing/ambiguous but I was pulling my hair out at the time! TP
