Old Fella - I am not disputing the accuracy of your (ATSB) figures, but as in all planning cases, they are theoretical and probably based on poor braking conditions. However, taking a practical view, those figures may be erroneous given the 'deluge' of the monsoonal rains at that time causing flooding on hard surfaces. What is not disputable, is the poor planning and badly executed landing that resulted in the over-run. (Also not disputable is the thread creep)!
Getting back to the original subject, 747Dieseldude, at 340 tonnes, you would have had a V2 in excess of Vmca( I no longer have 747-200 manuals, but is 157 knots close for Vmca?). If you were below Vmca, then directional control might only be possible by throttling back the good outboard engine, which would compromise the climb ability. Still, an interesting manouevre requiring accurate flying .
