Pence was onboard.

Alot of water around the end of runways there. Anyone know if they came near dipping into the water

It's hard to tell exactly looking at pictures on CNN. However the aircraft seems to be at the end of Runway 13 facing towards flushing bay as far as I can see.

Looks more like the it came to a rest just short of the highway according to FR24

FR24 shows the location at the end of runway 22

Yep sorry your right it's facing the Highway at the end of Runway 22 (Runway 4 end).

What looks like broken up concrete on the pictures on CNN seems to be the Runway Safety Area (RSA) which looks like is what stopped the aircraft going any further.

Missed opportunity there...

Is that technology in most airports? It seems to have really saved the plane from disaster

Is this not EMAS? aka Arrestor bed

That's it!

Looks like an interesting safety feature that I was not aware of.
Reading a piece on it, it seems it has to allow movement of aircraft and emergency vehicles without damage but obviously has to deform in the emergency situation.
It clearly worked in this instance but what type of material is it constructed of. As a Civil Engineer myself, it sounds like an interesting topic.

Hollow concrete in this case. Other forms exist though

It was originally designed after a number of over runs at JFK.

@mickdw, where did you get the idea that it has to allow aircraft to move over the surface in a non-emergency situation? AFAIK the EMAS isnt part of the runway area, therefore an aircraft will only be on it in the case of an overrun or a short landing.
Airport runways are designed using a Pavement Classification Number concept, and aircraft then has an Aircraft Classification Number, the ACN must be equal to or lower than the PCN to allow that aircraft to operate from the runway. In the case of the EMAS, they have to assess what is the lowest and highest ACN that they need to account for based on the regular aircraft using that runway, then the EMAS PCN is designed to be lower than the lowest ACN. This means that it will always crumple when a weight higher than the design threshold is placed on it, regardless of an emergency situation or not.

Looks like I misread a piece on it as i just scanned over it. It said something like. ... it should be capable of dealing with occasional aircraft without damage to aircraft or passenger injury. I wrongly took that to mean non deforming.
Makes more sense that it will deform in all cases otherwise design would be impossible. I was over complicating things, thinking about vibrations at overrun speed versus taxi speed and nose wheel forces when brakes are applied. All pretty much impossible stuff given that different aircraft will be involved.
Still, not as interesting as I thought. Just some low strength surfacing.
