I don't have the wisdom, the facts, nor the knowledge to make any judgement. I also wasn't there to observe what happened.
Maybe this has been mentioned before, I don't know, BUT I hear (this being ppRune) that the engines were derated more than reflected by the books. That A/C was an ex-Boeing A/C sold to Emirates (not that that should make a difference), having come from Singapore or some other outfit that changed to Boeing.
But the moral of the story is that any of us could have experienced the same as the (un)fortunate crew on that day, had we been using official data that was incorrect.
So , I take my hat of to the crew, irrespective of who is to blame. Let us rather look forward and learn from what happened (when the info is available) and correct the mistakes and forget about it.
Again, this is tsjust anuthzur rumour
Safe flying
