Surely the FAA has plenty of roles where people with those disabilities could work. It's not like they are trying to add a deaf person to be ATC communication coordinator or a paraplegic to be an emergency firefighter.

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?

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…

Plus a tire doesn’t affect the plane’s ability to fly so spending some extra time in the air isn’t dangerous. And it gives the pilots more time to assess the situation and plan.

It’s likely less disruptive to ATC at SFO too to not have them circling if they don’t have to.

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

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?

I 100% believe that there is a sizeable contingent of people that pay (more) attention to these things than they usually would. I am a tiny bit of a plane nerd. Weird shit happens with planes regularly, and not just Boeing ones. These events are increasingly making it to HN, and when they do, they’re getting far more traction than they usually do.

There is undoubtedly something fishy going on at Boeing, but that doesn’t mean that more commonplace accidents aren’t being comparatively overpublicised, or that they aren’t getting more traction than usual because there are now far more people waiting with baited breath to jump on anything that portrays Boeing negatively.

All I’m really saying that Boeing hate is now undoubtedly trendy, and that communities like HN are filled with people that have bought into the software engineer God complex enough to think that they can just intuitively understand something as complex as aviation. I’d barely consider myself anything more than a layperson but these Boeing incident threads are increasingly filled with people spouting BS. Again, there is certainly something going wrong at Boeing, but we are well into the territory where there’s a real need to separate signal from noise.

Obviously many eyes will be on Boeing given recent history but I don't know that there's a particular reason to suspect them. In this case I'd look first at possible maintenance issues on United's end, or possibly a manufacturing issue with the wheel/tire.

Yep. Completely logical. Boeing management is increasingly becoming a lightning rod for any issues that occur with Boeing planes.

By posting this policy you're implying it's obviously a problem... mark me down as undisturbed that there's a light thumb on the scale in favor of hiring blind/deaf/etc/etc/etc employees for what I'm going to reasonably presume are overwhelmingly office jobs sitting at a computer. To the extent they're even getting hired at all.

Of course the disabilities you'd primarily draw attention to would be instead "severe intellectual disability" and "psychiatric disability," I imagine. This program doesn't remove the qualifications for jobs: blind people are not flying planes. People with severe intellectual disabilities are not inspecting them.

Speaking of left/right divides, it seems to me that taking these kinds of policies at or beyond face value is another one of those. The anti-DEI crowd has also decried Boeing having a target to hire more black employees, a policy from 2021 that's resulted in the share of black employees rising from 6.4% to... 7.1%. Definitely a smoking gun. I can go on Twitter to hear about how that 0.7% combines with the lower IQ of HBCU graduates to explain the company's problems.

I have a flight coming up on United’s 777s out of SFO…. Fantastic

Don’t buy into this hype. Consider how many 777 flights have had absolutely no issue, and that commonplace redundancies made this a relative non-issue for passengers.

The video shows that the tire didn't come apart. It looks like the wheel came off with the tire attached. For just the tire to fall off whole, lots of bolts holding the two-piece rims together would have to not be bolted, and half the rim would come off, anyway, vs. one big nut holding the wheel to the hub.

Still, hard to believe either way: The wheel nut should have something like 250nm of torque, and it has a locking device, and swapping a wheel is a two-man job.

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.

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.

Don't fret.

You're hearing about this because aviation accidents _don't_ happen.

Boeing is under serious fire largely because of four (extremely terrible) accidents.

Hundreds of thousands of planes fly every day.
