I would think this is most likely a failure by the maintenance department and not Boeing themselves but wow do they not need to be in headlines again.

If it is a maintenance failure, it's a really big one. You would have to change the tire (really the whole wheel) before this flight, not put the wheel nut on, and not put the wheel nut lock on, and close the wheel nut cover without having done that, probably with a second person there, and have the wheel somehow stay on while taxiing. I think I see the brakes still on the axle in the video, so I suppose this is what…

I once saw four tires pop off on a modded hatchback racing down third ring road in Beijing around 2AM in the morning. The only way that could have happened is if the guy just got the car from the shop and someone forgot to add any lug nuts at all. Completely believable in China I guess.

One thing I won't ever understand is why we allow large airports to be located in a way that puts any kind of infrastructure, be it residential, commercial, transportation or recreational, under the flight path for critical phases (i.e. start/land). Right where I used to work there's a memorial placard for a plane that crashed in 1960 due to an engine failure [1], and maybe five minutes worth of walking from where I…

You’re confused about why transit hubs, whose purpose is to move people, are built where the people are?

takeoff around 11:24am: https://www.youtube.com/watch?v=haRC034bj-g landing around 1:17pm: https://www.youtube.com/watch?v=kkdKhZSZiSM towed to the gate about 10min after landing you'll have to scrub because the streams are still live and I don't know how to timestamp a live stream

Why did the plane go all the way to LAX rather than landing back at SFO? It clearly seemed to be considered serious since there were emergency vehicles by the runway as a precaution. Is it easier to divert to LAX rather than land back at SFO in this situation?

Any unscheduled landing due to a fault with the aircraft is met with emergency vehicles, even if the reason is minor.

And somehow all the replies are blaming DEI or affirmative action. Twitter's really gone off the rails.

Somehow the "anti-DEI" people really latched on to Boeing. Not just Boeing themselves but also pilots for some reason... maybe spurred on by the fact that the pilots of the Alaska flight were both women? Not that the pilots did anything wrong in that incident, of course. I can't really tell if the fact that Elon's been very active in this... let's call it "discourse," is a cause or symptom of it being so oddly widesp…

Witchcraft!

(But yeah, blaming the _pilot_ for the door plug falling out seems particularly perverse.)

assuming there's a statistically significant increase in these kind of accidents: what's your theory on why this is happening? what has change since e.g. 5-10 years ago?

Well, first of all I don't actually think there is? It's clear that the 737 MAX is a particularly problematic design, but industry-wide incidents and accidents vs distance flown continue to fall, and have for decades; even _absolute_ numbers of deaths are falling, despite vastly more planes in the air.

As to the problems with Boeing in particular, they mostly look like cost-cutting and short-termism; the 737 MAX, for instance, is transparently an attempt to squeeze a few more years out of an ancient no-longer-fit-for-purpose design. And the decisions that lead to that were probably made more like _20_ years ago; Boeing should have started developing the 737 replacement quite a while ago. This would suggest that Boeing has poor leadership.

(You could also argue that some of it's the unfortunate reality of the markets; the markets _might_ punish Boeing for making necessary investments with very long pay-off times.)

Twitter artificially promotes bluetick replies, and most people who pay for Twitter are... a bit odd. I expect if you were to filter out the bluetick replies this effect would diminish a bit.

Earlier quoted context omitted.

Boeing is going to fix this by installing tyre _presence_ sensors.

Nah, they'll be going for the latest iteration of TriMCAS - Tricycle Manoeuvrability Characteristics Augmentation System - which makes the plane behave more or less like it should plus or minus some tyres. They'll make the whole system dependent on a single ABS sensor in one of the front wheels though so if that wheel happens to fall off the plane will ground loop upon touching down.

With no manual override.

I'm curious what the pilot's experience was like. Do I get a notification right away that a wheel fell off or was it a radio call from air traffic control? While I'm in flight, do I have a little camera or something where I can see the wheels? Because there's no way to actually go look at them when they're tucked away and you're flying, right? In other words how did they determine that they should still attempt a nor…

Someone has already stitched together the ATC/plane radio traffic[1], it sounds like the pilots on the plane initially had no idea. Oakland departure had to tell the pilots that people on the ground saw something falling off the plane. [1] https://www.youtube.com/watch?v=BeGo79nRMwU

So what I'm hearing here is, if I see a tire fall of a plane, I should, like, tell someone, who can eventually get word back to the pilot.

Boeing shares seem unaffected by this event. Poor Boeing, this is what happens when you lose your “soul” as a company and you start chasing margins, profit, dividends and you don’t pay attention to you people and your product. Have seen it happening in many big companies, and I don’t understand why intelligent/educated/competent CEOs don’t see this :-(

> Boeing shares seem unaffected by this event.

Probably because it's considered too big to fail. It's pretty much backed by the US gov.
