Looks like for this airport they don't follow ICAO regs either for runway design. The steep slope looks to start about 60m from runway centreline. Isn't there supposed to be a runway safeguarded strip area in the region of 150m from centreline?

In the video in post 43 there seems to be a flash during the landing roll. Could there have been a reverse surge on the right engine and the left engine remained in full reverse? In the early days of the 747, the P&W -3A engines were notorious for reverse surges. On a wet runway, if you didn't cancel the reverse immediately then you were off the side.
My money is on crew safely decelerate the aircraft to taxi speed despite obvious landing roll distraction. **Both eyes inside cockpit**, L MLG veered in the grass and the rest of the aircraft follows, 10-15 knots would probably do in this case.
As the video was shot from the cockpit of the plane waiting at HP 11, most probably it was wig-wag runway guard light.

The Turkish authorities may very well need the assistance of the Egyptian Air Safety Committee to establish beyond doubt that the answer to the cause of this event is never adequately explained.

Here is a video of another landing. As a SLF one does wonder about the plane turning left before making the 180 turn. Can it be that something went wrong while they were doing that? Maybe they were too fast while trying to make the left - right turn?

To me just an indicator of the workload in the cockpit at the time rather than a cause

Engine surging in reverse is typically caused by high EPR and low runway speed

I have seen bird strikes get caught up in the nose steering cables on 737’s before. The cables are exposed once the gear is extended. As stated previously when rudder effect reduces during deceleration, the (possibly) displaced nose wheel would start to have an effect.
We will have to agree to differ. If you freeze the video at 0:10 you will see that the flash comes from the right side of the aircraft just ahead of the green nav light. It looks very much like a reverse surge to me. I have had quite a few of these and they are very distracting.

I would not be so sure about that OEI going around meeting 5% climb gradient.

I wonder whether some scenario like on S7-778 may have happened (right T/R inop, forward thrust applied instead of reverse thrust...).
They obviously have to use full runway to do a 180° backtrack, so they may have stopped breaking and just "let it roll" some distance to quickly get to the turning area...

Its clear it went over the edge with very little forward speed, or it would be a lot further down and more damaged.
My money is on - They were doing the backtrack turn (as post 70) and put the nosewheel on the grass, at that point they would have had no nosewheel steering to speak of. Then symmetric thrust just carried them straight on over the edge at taxi speed. Possibly combined with TR being taken out with remaining N1...
