It's also an option, not all Airlines opted for it, and I think not many more will after this event!
Once again,
To: Captain Sullenberger & his Crew, While I realize you feel as if you were just doing your job, I don't think the same outcome would have happened with many other Crews out there! Great Job Sir!
To: The normally indifferent NYC Ferry-Boat Crews, Thanks for helping out.
(A couple of more minutes though, I'm sure Sullenberger & Crew would have figured out a way to drop his Nose Gear and then he would have taxied it up to the Boat Ramp just so his passengers would have received their Frequent Flyer Miles. The man is amazing!)
