I figure they would have burned off/dumped all excess fuel before attempting this. The sudden explosion surprised me a bit.

edit - The whole plane seems to stop moving too. Did it reach the end of the runway and hit something on the ground?
IIRC, the 737 doesn't have a fuel dump system. Maybe newer models do, but I know the older ones didn't.

It slammed into some kind of wall/berm.

removed for speculating.
More likely not. Engine parts. Turbines, flaps, ailerons. Underwing engines, fuel loaded wings. Did not explode until later.

Don't think those were people expelled from the plane. That would have caused the plane to roll or pitch, in my very limited opinion.

Confused why that aircraft attempted to land that way.

Everyone hoping it was a 737-MAX will once again be disappointed.

It was a 737-800 so if the problem was with the landing gear, going to be a maintenance issue, unless there was some really freak external event that ripped off the gear like a bird strike or massive turbulence.
That would be a BIG ****ing bird to take out all the gear....

That's my point. Only some kind of insane event could rip off the gear (which isn't what actually happened).

We can rule that out based on that video, however unlikely it ever was

I fly almost every week (makes ya think), but one time coming back into Mexico City when I was living there our landing gear wouldnt deploy and we kept flying circles around the city and pilot finally came on and told us issue as we were running out of fuel and said to prepare for emergency landing and they were going to give it one more go around and thank God, somehow landing gear deployed and we landed without incident bit it was tense for a bit. After that though, I cant watch videos or movies on plane crashes, jsut cant do it.

So if that was bird strike on takeoff they are full of fuel. Looks like only one engine was impacted and that aircraft should be able to fly and land just fine on one engine. Not sure why the landing gear wasn't deployed and its hard to tell but in the first vid that only looks like the last 2500' or less of runway. I think they touched down late. The big dust cloud tells us it ran off the pavement and then obviously hit that berm.

Its early but that should not have happened with that aircraft.

I can't tell from the video but are the flaps/slats deployed? Seems to be really fast for a landing and way, way too far down the runway.

it looks like the bird strike occurred upon low approach and not on takeoff.

Not sure how that would impact the gear though.

This is me too.

Was just on a 737 flying through all that weather today. It's just too much to worry about. So I avoid all of those types of movies and disaster pron shows.

Looks like the thrust reversers were deployed:

Video of bird strike looks like plane was headed North. Looks like video was taken from a "Resort" on a beach south of the airport.

https://maps.app.goo.gl/MscTNkKt3Wvx2gRb8

Attempted landing looks like it was headed south bound.

ETA Maybe a downwind attempted landing?

Aghh that timing alone may explain alot. Again its early but I don't think the cockpit kept their cool.

I cant tell on the lil screen with my old eyes but were the speed brakes deployed?

Horrible for the casualties. Prayers for them and their families.

This seems really sketchy. How would a bird strike prevent the landing gear from being able to lower?

Is it possible the pilots panicked and forgot to lower the landing gear?

It's potato quality, but it looks like flaps are deployed on the video when the bird strike occurs.

there is a very loud reminder popping off coming in at that speed and altitude with gear up in the 737-8 series

Reddit comments think pilots attempted a TOGA too late, hence the speed.

Other comments & vids think both engines ingested birds but only #2 flamed out.

There's no reasonable situation where a birdstrike would prevent all the gear from coming down

Do you have another video? The video in the OP doesn't show the touchdown

I saw this on the aviation thread posted earlier, but they hadn't confirmed it was the same aircraft yet.

If one engine was disabled and both were applying thrust, it wouldnt have gone in a straight line, right?

I guess that means both were low thrust and it was just momentum carrying them down the runway, but it certainly looked like some of the dust off of the starboard wing was involved in wake turbulence.

Could have also been smoke from the bird strike. I just cant imagine that level of sustained momentum unless they only used a fraction of the runway.

I can't speak to the Korean carrier here but landing gear up in a 737 generally calls for shutting the engines down on touchdown. Trying to use reverse thrust could result in extending the landing distance after the reversers deploy and and are ripped off and the engine hypothetically remains at a higher rpm

Right. The engines were clearly not shutdown, though.

I suppose we will find out all in time, but it didnt look like the thrust reversers were activated.

I think you have something here. If they weren't attempting TOGA, this might explain the nose staying up the entire time.

From the airliners.net thread, many folks on there saying that the nose-up orientation is standard for a gear-up 737 on the ground, due to the geometry of the engine mounting (very low and forward).

The picture that JB!98 posted above clearly shows that the thrust reversers were activated (what looks like a black line halfway back on the engine cowling. What we don't know yet are the engine power settings and how much (if any) actual thrust was being applied.

No other. Films.

The runway is over 9000'. The clip was maybe 2000' if that much.




So why are you speculating on where he touched down?
