The crew of a modern commercial airliner has managed to succesfully ditch (land on water) the aircraft, with all on board surviving, no less.

US Airways Flight 1549 apparently hit a flock of geese shortly after takeoff and suffered a double flameout (engine failure). With nowhere to go, the pilots apparently decided to avoid the downtown area and attempt a ditching on the river.

A job well done by the pilots, cabin crew, ferry staff and bystanders in assisting, and of course from the early reports huge kudos to the passengers for remaining relatively calm and doing as directed in a very alarming situation!
You can see them here, standing on the wing awaiting rescue by boats which I've read were on the scene within two minutes- must have seemed a lifetime in that cold water!

The plane stayed afloat for a good 50 minutes, I always suspected that with the right conditions (and a bit of luck) that this could be achieved.
I've said it before, and I'll say it again... pay attention to that safety briefing... this could well be what saves your life, as it has for these lucky passengers and crew of US Airways 1549.
Well done crew!
