Awful week for aviation with the South Korea crash today, no idea how anyone at all survived it.

That’s a strange one.

Looks like a perfectly good, controlled, gear up emergency landing that goes hurtling off the far end of the runway into a wall(?).

Going to need more info than I’ve seen on that one!

Some Korean website has footage of a bird strike and flames coming out the engine as they were descending to land, that wall at the end is ridiculous gave them no chance of survival.

Think it's intentional. A plane that managed to clear the runway could have ended up on a highway that circles around the airport and risked causing even more casualties.

That’s why they have arresting concrete!!!

La Guardia in NYC has water on one end and a major highway at the other end of 04/22. At the end of 22, they have multiple layers of arresting concrete [Engineered Material Arresting System (EMAS)] to stop an overrun.

The fourth generation EMAS arrestor beds are composed of blocks of lightweight, crushable cellular concrete material, encased in jet blast resistant protection, designed to safely stop airplanes that overshoot runways. Zodiac's EMAS is installed on over 110 airport runways at over 65 airports on three continents.

Works great!

Not sure why a bird strike and engine failure, unless it was both engines, is a big issue, or why they had no gear down???

LOTS of unanswered questions!

The black boxes have been recovered so the truth will be known soon enough, awful accident them pilots seeing that wall approaching and knowing there is nothing they can do.

I’m surprised they didn’t try some rudder control to slide OFF the side of the runway to help arrest their slide.

Working on the basis that both engines had failed and the landing equipment couldn't have been deployed they may have done well getting it down but I did wonder what they could have done anything to slow it down more on the ground. Handy having pilots on here.

On Google maps street view, the wall only seems to be a single layer of breeze blocks so I'm surprised the damage it caused.

The 737-800 has 3 manual gear handles on the cockpit floor. However, it may not have been their first priority if landing without engine power and no flaps. It takes a moment to achieve and their concentration may, indeed, have been on landing “safely” on the runway.

All if this assumes no engine power, no electrical power (because they didn’t start the APU with Loss of Both Engines checklist) and no hydraulic power to get the gear or flaps down. This should all have already been accomplished by 1500’ above the airport, but the lack of ANY flaps and no gear suggests a higher altitude bird strike.
 
Probably get rightly corrected by some and never worked on the 800
Think 800 has 3 hydraulics systems which the landing gear will be connected to by both engines,so even with 1 eng failure you should still have hydraulic power from the other .
Theres a R.A.T. which pops out after under certain hydraulic failures but theres still has to be fluid in the system so I can only imagine theyve lost all hydraulic fluid, even then a lot of aircraft will drop the undercarriage under gravity because its a hell of a of a weight
Few small airports have concrete jet blast areas esp if theres a road at the end .
EDIT Actually after further invest the 737 800 doesnt have a R.A.T so all stated is completely wrong for this aircraft.

Could a bird strike really cause such catastrophic and multiple simultaneous issues?

Again stand to be corrected but modern aircraft have a ram air turbine R.A.T which pops out under emergencies
provides limited electrics and hydraulics for the essential bus bars and hyd esp under engine failures ,happens automatically under certain conditions.
A.P.U.s can take a while to start,so if your struggling with shit happening and time limited wouldnt have thought its your go to, but as usual will be corrected .

It would have to be multiple bird strikes causing a dual engine failure and loss of hydraulics. It would be like the Miracle on the Hudson, albeit that was an Airbus 320, not a 737-800.

Why they didn’t have gear down remains a mystery to me, but it might have been task saturation. I think it would have been very, very helpful to them, but I wasn’t there and won’t second guess them without significantly more information.
 
The video shows how horrific the situation was. It looks completely hopeless. A despicable scenario for them to be in.

RIP.
 
My limited understanding Hudson with no engine power and limited services had no option but to ditch as he would never had got back anyway.
Korean is different as he was lined up on the runway.
As stated hopefully wasn't pilot overload, but if it was, its very understandable. but there's is many config warnings to inform you of the landing set up,but in an emergency and not a great deal of time who knows .
