steering without nosewheel

Do modern heavies all have differential braking on the main gear? Could this be used to keep the a/c on the intended track (on the ground)? Is this controlled by the foot pedals as in light aircraft? I'm sure a lot of us SLF would like to hear from an ATPL.

Use of aft slides only

More likely the Captain decide there was a risk of fire where the fuselage had scraped down the runway and chose to use only the aft slides.

Yes to all.

Not only modern heavies. I flew Boeings 737 767 777 747. They all had differential braking using ruder peddals.

Re: mross,

Yes, all modern heavies have differential braking to assist in steering the aircraft. On my current type, we are actually able to dispatch with the nose wheel steering inop. Though, if I actually would, and with passengers, is another matter.

That said; in a cross wind large aircraft at low speed have a tendency to weathercock and it can be difficult to control with any finess the direction of travel. Add into this, no nose wheel and a cambered runway.... You get the picture.

C-list

From the video you can tell that it went a very long time before they started with the Evacuation C-list. If they performed it at all. From pictures you can see that the GND spoilers are still UP after the PAX had left, which indicates that they didn't perform the Evacuation C-list OR they performed it unsatisfactory as the second item on that list is SpeedBrake lever DOWN, a Captain's item.
You can also see that the flaps isn't in 40 degs, which is the position the FO should place them according to the same Evacuation C-list.

A horrifying situation to be in, and they were all OK. That is what counts. They overall did a good job.

First, in interviews people say that nobody knew something was wrong, but on the liveleak video one guy says "and thats the impact" as if expected. Did he know something was off already?

OMG, they closed the airport temporarily!!! WTF? What a silly move to make, don't they have enough fire cover or runways to keep the place open?

Cabin crew make an announcement "ladies and gentlemen we are not there.. please sit down"

Perhaps she did not realise they were in trouble and the "there" she refers to is the gate?

The video is a video of the video taken on an ipad, so there's commentary over it.

So the CC think that's a normal landing?

Remembering a number of nose wheel or other u/c incidents previously declared I recall News choppers etc expectantly awaiting the 'crash'.

The lack of external coverage suggests to me the was a sudden and loud twang.

Obviously used to heavy landings.

I very much doubt that, the lead Cabin Crew member has to keep order until the Captain has initiated an evacuation procedure.

Also just to ask why were the doors 1L and 2L closed but the left overwing exit opened? Also there seems to have been a delay in opening door 1R but also the right overwing exit was opened plus door 2R meaning for a short-period evacuation was solely through both overwing exits and door 2R, it seems 1R opened with delay. Seems there could have been a problem with the doors although its possible the Cabin Crew deemed the Left side unsafe.

Re evacuation
I know only one person who has been in a full scale emergency evacuation as a passenger and he was the one that initiated it.
The cabin crew did not.
He was seated at an emergency exit and was a long time airline employee. He judged the situation safe and went.
That is exactly what I would do.

Unsafe gear indication

Surely there must have been an unsafe gear indication?? Looks like nose gear doors and assembly did not open) If so why not request appropriate emergency response? Could it have been a hard nose drop during de-rotation?Mysterious...

If true, then not only is there a question of an unsafe gear indication but how did this occur at one of the US's busiest airports in daylight and good weather, without someone spotting it.

Which runway did it land on? Even coming in over the East River you'd think someone would have seen it!

"after the landing gear unexpectedly fell off the plane"
Well, I'm not too sure it's not far off what happened

Looking at that video, it seems to me the nose attitude falls in the last few seconds (~0:19?) - about as the aircraft transitions from grass onto hard (taxiway?). Nobody seems to be allowing for the fact that the "off road" and back "on road" excursion may have caused the NLG to fail?

Why the excursion started who knows, but KLM had a similar "off roader" at BCN after a bird took out the NWS cable(s).

And in the same way that passengers who evacuate with their carry-ons get away with it, the disobedient ones who take videos during landing will escape sanctions. I suppose they rationalize it by claiming their use of forbidden equipment will aid the investigation. What part of TURN FULLY OFF do they not understand?
