How good/technically adept was that landing on water?
Not somethign you'd train for?
I trained for it but its such an unlikely scenario that you never expect to have to do it, the chance of survival is pretty slim unless the water is v calm as it happened to be that day.
The only time usually that you would aim to ditch in water is if you had no other option like stuck over an ocean i can't think many people have even attempted to land in a river.
So yeah although it's easier than it sounds like it might be to ditch on calm water he still did a ridic good job to keep the plane intact, the CRM displayed by that transcript shows perfect captaincy imo he made quick decisions that he committed too, he briefly asks for FO input but then maintains his decisiveness and keeps calm making him and the FO highly efficient, noticed on the wiki link that he worked on the CRM programme at US Airways so i guess its not surprising.
I guess what i am saying is the passengers that day were lucky to have such an excellent flight crew that day, not for the technical know how of putting the plane down safe but the execution of everything else.
