On landing power off or in Hudson etc:
The control of the aircraft with no power or multiple system failures is well within capabilities of today's systems, although not widely implemented since the current approach to automation is to let the pilots handle the unexpected.
The wisdom of that is a whole other thread, see AF477.
What is a more difficult task would be the decision to land in Hudson.
I believe that is where deep experience saved the day.
A low hours pilot would possibly gone for the Teterboro option with probably 'sub optimal' results.
