Boeing stock opened down 5% in overnight trading.
Because most people are stupid and somehow think it was either a 737 MAX, or even if not, it is still somehow Boeing's fault.

Hell, Fox News is doing everything it can to blame Boeing.
"If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves." - Sir Winston Churchill

That didn't happen. No hydraulics looks the Souix City crash…if they're so amazingly skilled and lucky to even make it back to the airport.


737 is small enough that there's a manual reversion even with both systems failed. It's harder, but it's not flying only with engine thrust hard.
Again, we've not seen anything to support the loss of hydraulics and resulting loss of flight control. If anything, much the opposite.

Agreed. They were in firm control of the aircraft upon landing. The configuration of landing is what is confusing, or possibly negligent.

Until we hear what was said in the black box, I am guessing the pilot purposely belly landed the plane. I think he was afraid of stalling or even flipping the plane if he changed the airspeed (on one engine) and came in hot. Even when he realized he was floating and landing long, thinking at worst the plane skids off the end of the runway, not realizing that the LOC antennas were on massive concrete blocks.


We've not seen anything from the multiple videos so far to indicate any actual flight control problem that warranted no landing gear.

But the drag of the dead engine and yawing caused by the movement of the centerline to the good engine, he had to be working that rudder, mind occupied with the concern of yaw and roll at such low altitude.

Speed had to maintain, higher than flap speeds and he knew he could not touch down until he bleed off some speed and that means a shorter runway.



That's ridiculous.

Suspect a complete hydraulic failure explaining the lack of gear, flaps and ground spoilers deployed. Even still, doesn't explain why they didn't declare an emergency and manually extend the gear. Odd ordeal. We will know once the FDR info is released.
Then how does he get back to the airport and land level on an actual runway with no control?
These aircraft have redundant hydraulic systems that are complex with some flight controls backed up with mechanical actuation in case of hydraulic failure. That said, nothing about this ordeal makes any sense.
Sorry but your two statements in bold are in conflict after you expand the quotes.
I can think of a scenario where they lost one or possibly 2 of their hydraulic systems, didn't troubleshoot the issue properly, where still able to fly the aircraft (pitch, roll) but failed to drop the gear.
Keep in mind, most modern aircraft can still fly with only one of their hydraulic systems operational with a limitations and extra workload.

The loss of hydraulics is not an excuse for having no landing gear down.



In case you missed it earlier. Gear can be dropped manually by gravity. They had flight controls, they likely just lost awareness.

If they had dropped the gear, this thread would likely not exist because the pilots performed nominally as if the gear was down.

I know that. I mention d it in an earlier post.

I know the true investigation and report will take months but will the CVR be released publicly before that or ever?

Because it was a Boeing jet?

I believe so, yes. Boeing wants to know why their plane crashed

Could be wrong but they often get involved....and regardless of what we believe, they are the gold standard in aviation crash investigations.

It's similar to how French authorities are involved in Airbus incidents.

They are and you are correct, It was my ignorance asking the question. I had no idea. Now I know,

There are procedures refined over 50+ years of 737's operating. Your "spitballing" is nonsense.

The nose-up during ground effect is also puzzling.

If you were trying to land a wounded aircraft, why would you be nose up? That's going to continue to produce lift and reduce friction with the pavement, right?

Yeah, can't take the opinions of some of the mainline airline pilots here. They're probably all young, minority and military trained. Those opinions can't be trusted.

I mean you're not going to try and be nose down, for obvious reasons. I think the procedure is to flare like you normally would, which would mean nose up.

Fair, but, I mean -- using only 25% of the runway is also not a great idea.

It is my understanding South Korea invited them.

As quick as some are to blame Boeing you're just as if not quicker to blindly defend Boeing. Quite fascinating

Boeing is a gov sweetheart company. For years they bought back their stock with extra cash, then when the pandemic hit, they held out their hat for taxpayer bailouts. That's why people hate on them. They should have gone thru ch11 like everyone else who gambles with their business.

We don't know if any landing gear issues are the fault of Boeing, but if in the meantime people don't want to hold that stock, they aren't "stupid".

My guess at least has aeronautic principles of thrust vs drags, you have nothing but condescending, sour notes.


737's land single engine all the time. There's a procedure for it. It will land just fine at flaps 15, flaps 30, or pretty much any flap setting. A pilot trying to become a test pilot because he thinks he understands "thrust vs drags" is how to unnecessarily kill 180 people.

I think we can now confirm that the lack of landing gear caused the accident.

The evidence that it was a failure of anyone but the pilots of the aircraft has yet to be presented.

That's what we all hope the CVR analysis will reveal. It's not normal for ground effect to keep a jet in a flare state for that long before touching down.

Anything more is just conjecture.

Gac06 is a pilot.

The dude in that latest video knows every nook and cranny on that jet. He never said anything like what PA24 is saying. That jet can be flown with a single engine and there seems to be no rational excuse for the gear not being down.

Yeah, that's what I said, don't know who's fault yet. Hard to believe that 2 pilots would both forget/fail to fully drop landing gear in time. There was also another landing gear issue with same airline.
