I think a robot would have coped with a little help from some remote team. Deciding on landing at the nearest airfield after an uncontained engine failure (and the other failures) would be part of the standard programming even if the remote team did not command it. The difficult bit would be deciding on the evacuation etc without someone competent to make those decisions on the scene.
I am not saying a robot would be best in all circumstances. But we should remember that there have been plenty of cases where the human was the problem (eg Air France 447). The question is which setup would kill more people, humans with autopilot or robots assisted by humans? I'm saying that as robots get better the balance point will be soon if it has not passed already.
