It doe's have tones of the SQ "incident" at AKL a little while back, as well as the one in JNB. It makes the hair stand up on the back of my neck to think of the cockpit atmosphere in last few hundred meters of the rwy!
T/O performance data errors have been a recurring theme in mishaps for the last couple of years, perhaps it's time for a closer look at more double checking/belts and braces systems for performance data, before one of these 'incidents' produces a less happy ending?
I do feel for the Crew though, very much a case of " there but for the grace of god... "
Buggs Out
P.S. Ymml rwy 34 is just under 12000ft, assuming they used the full length.
