I remember watching an episode of air accident investigation on national geographic a year or so ago. It was covering the Ethiopean 767 that ditched. They then had a very experienced expert saying that under any circumstances ditching in a commercial jet will always end with the aircraft disintergrating, as the engines will scoop the water up decelerate and maybe tear the wing off.
Well fairplay lads, many americans take the mick out of USAirways for their poor time keeping, but you can sure fly your aircraft.
