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?

SFO only has one NS runway open now. Mucking the other would be a show stopper and the others are usually departure only.

As yes, it was the female pilots who made MCAS and forgot to put the bolts on the door...

Like, I get that people have always been dumb, but man are they loud and aggressive about it these days

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.

Normally I'd agree, but these days I ain't going if it's boeing and I honestly wouldn't assume that anymore.

Hmm, seems I'm not the only one.

They were above-weight for an emergency landing at SFO. Also, with the loss of one tire, even if they were within weight for an emergency landing, the additional pressure on the remaining tires from the full fuel takes could have caused a catastrophic incident. In other words, it was safer for the plane to continue to its destination, since the reduced weight from fuel consumption during the flight would make a landi…

But its destination was in Japan.

Logistically, I'd think it'd be easier to have the plane return to SFO (potentially after burning off fuel) rather than going to LAX.

Who manufactures plane tires? How much do they cost? What about fighters and bombers?

The same companies that manufacture car tires-- Goodyear, Bridgestone, Michelin, and probably most of the other major manufacturers (but those three definitely all have aircraft tire businesses). They're probably not cheap.

About $6000 per tire in the one source I found, which lasts anywhere from 2 to 4 months depending on how many times a day it lands. Bridgestone manufacturers tires for the 777 but it’s not clear if they made the one that fell off

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?

The left and the right live in completely separate bubbles. You may not be aware of this story, but the right is.

See https://www.faa.gov/pwdp . The Federal Aviation Administration has set a target of hiring people with "severe intellectual disability".

> The Secretary of Transportation has set a hiring goal of three (3) percent per fiscal year for individuals with targeted (severe) disabilities.

> Targeted disabilities are those disabilities that the federal government, as a matter of policy, has identified for special emphasis in recruitment and hiring. The targeted disabilities are:

    Hearing (total deafness in both ears)
    Vision (Blind)
    Missing Extremities
    Partial Paralysis
    Complete Paralysis, Epilepsy
    Severe intellectual disability
    Psychiatric disability
    Dwarfism

Edit: If you're into podcasts, listen to this (partial) episode of Blocked and Reported about a different FAA scandal about flight controllers training (the tests were changed to promote trainees who hate science and love risk): https://www.blockedandreported.org/p/premium-the-faas-bizarr...

they have tire pressure sensors so I'm guessing that the pilot would get an alert that the tire pressure info for that tire disappeared

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

But only sometimes. ;)

My personal theory would be that the change in Boeing management is catching up to them. But like the anti-DEI folks, all I have to base that on is rough correlation. I certainly wouldn't try to make a case based on that alone.

LAX might be a better option for the airline, as it is a larger airport with several alternative flights towards Japan where passengers could be shuffled into.
