Why the hell would anyone start thinking that the crew made some mistake?
Let me say what is on my mind -
1. The crew did one fantastic job!!!!!!!
2. Anyone blaming the crew needs to go take a swim in the same river!!!!
3. From the look of it - it is highly probable that the aircraft lost both engines which is not difficult if a single bird the size of a duck can take out the engine on a wide body the chances of it happening to take out both when striking a flock of birds with multiple birds going through the engines are very high!!!!
4. Can't you for one minute except that sh!t sometimes does happen and it is pure skill and probably years of experience that saved the people on board!
