Since some folks see fit to speculate on the performance of the crew at a time when zero information is available to say what actually occurred, let me add the following:
I have no idea what happened leaving ZSPD, but I know first hand that at least one of the crew involved had demonstrated the ability to handle problems at high speeds on takeoff. My one and only high speed RTO in an MD-11 took place in 2008 with one of the 3 deceased in the left seat (I was in the IRO chair). Departing Conakry (not the longest runway on a hot day...) at somewhere north of 100 knots the plane shuddered a bit and the engine fail lights illuminated. He called for and performed a flawless RTO.
That was the tail end of a great week in Jo'Burg and Ghana together that I will never forget so long as I live. RIP Bro.
