structural integrity...well other ditchings have allowed the plane to be pulled out and used again. should say water landings I think.
airmanship...the landing on the hudson was like any other landing...wings level, nose up ...that's pretty much like other landings so there is no loss of skill set there.
and yes, looking for a place to land should be high on the list of priorities...and really to be very good, you have to know where to set down when you can't see out the window.
