If that plane ditched, would all the passengers survive, just like the Hudson crash?
There's no way of even trying to guess that. Just like a car accident, there are no guarantees in airline crashes, either. But a bird strike does not mean a bird got ingested into an engine. Perhaps the bird hit the windscreen or the wing. Chances are, the bird probably hit the wind screen (or near it) since they reported the strike. Plus, they were already on final approach so, even if the bird got ingested into an engine, the aircraft would have more than likely made the airport and landed safely.
