Those who mentioned Ethiopian Airlines 961 and said it wasn't successful should remember that many people who didn't make it out inflated their jackets INSIDE the plane, getting trapped as the fuselage sank. So yes, Ethiopian was technically a successful ditching, but it reiterates the importance of listening to the safety briefing.
My hat off to the f/c in this instance. Well done guys, that's why we have the faith in you up front. That all pax made it out ok is very good news, especially in the temps they have in NA around this time of year (I wouldn't want to be floating in the Hudson in winter).
No doubt the airframe will be recovered, cleaned up, inspected and put back to use?
