According to expat that's intentional. Probably the reason it was successful.

It would also be interesting to see if the engines are still on the wings or not. This would indicate what sort of landing it made. If it "landed" on the water they would normally be ripped off, as they are designed too or if they are still on, possibly indicating that the pilot stalled her onto the water tail first.

Indeed. If they both shear almost instantaneously then the deceleration will be hopefully linear and less abrupt.

I was watching BBC news, and they said the plane will try to be raised tomorrow morning. They also used FSX to show a "reenactment" of what happened (got better fps then my computer Grin).

Oops. I should have read more carefully.  Embarrassed

That's the problem with having 4 separate topics on the same subject.

Exactly Grin I have just written in one of them that all cigar tubes have this. The engine to wing pylons have shear pins designed to shear on impact and shed the engines. This is for two reasons. If the aircraft lands on water and the engines do not come off, then they will cause the aircraft to nose over and/or rip the wings off (this goes for a wheels up on rough ground too, though, personally I would go for the water option......drowning has more appeal than burning to death Sad) . Also just like Indy car and F1, they are designed to come off in the form of energy dissipation. As many of you know I spanner on 737 and A320. During engine change we have specific maintenance orders to make a visual inspection of these shear pins for seating and corrosion. I have to say I was always skeptical and thought that this function was a water tank testers dream..............Hats off to Airbus and the Captain of course. Without very level wings it would have ended in tears like the Hijacked Ethiopian Airliner.

You're refering to the one that ran out of fuel, ditched near a beach, and cartwheeled right?

Yes, pretty much the same thing. Non working engines are non working engines however the Ethiopian 767 was effected by shore breeze at the last second which caused it to drop a wing. Nothing that the pilot could do about it in that case.

New video just out on MSNBC showing the plane hitting the water.  It looks like a surveillance camera on one of the docks there.

Can't quite believe that in such a tourist rich environment that no one noticed an A320 on final approach into the river, yet when a celeb drops the ball the whole world seems to get it on film.
