I found it interesting that Boeing did proactively tell airlines to inspect 737 MAXs for a possible loose bolt in a different part of the plane (rudder section) at least 8 days before the January 5th event. Example story: https://www.reuters.com/business/aerospace-defense/boeing-ur...

Unfortunately, Boeing did not know they had other issues with the plug door bolts.

That is not what I said

But when you have a quota, then you must ignore better qualified applicants in order to satisfy the quota. It's a mathematical fact.

I am not saying this is the reason why Boeing is turning to shit. But it's an interesting observation.

I myself am a "minority/POC" and I'm also extremely competent at my job. So I'm not saying that minorities are incompetent, because I am not incompetent.

When I interview candidates I give zero fucks about their colour/gender/whatever. If they are morons then I won't hire them.

At what point do consumers en-masse refuse to fly on these aircraft, if ever? When there's a few more fatal crashes?

Maybe when airlines start advertising that they don’t use the new 737s. The more likely scenario is that the Chinese or Europeans will ground the new 737s until some very expensive fix is put into place and not accept any workarounds. That would probably make a difference. FYI: https://qz.com/1569865/china-grounds-737-max-8-after-ethiopi...

There are mutual recognition agreements between the regulators and if the europeans try something like that, the americans can create counter measures to even the field in a mutually undesired spiral. At this moment, the biggest enemy of Boeing is Boeing itself.

It seems there's a sense of malaise falling over everything and everyone in the USA. People at large simply cannot be bothered to care about anything, including torque specs for freakin' AIRLINERS

I know of a pretty famous car tuner in the US (I won't get too specific for various reasons) and despite most people in my community going to him for service over the years, multiple people have come out and proved he rarely if ever torques anything to spec. For the longest time he even allowed customers to watch in the shop space as he worked on their cars and he'd hand-torque many things that the car manual was ver…

Probably one of those guys that says "click!" whenever they tighten a bolt.

Could AI help firms like Boeing perform more robust and automated safety checks? I'm curious about how much an issue like this can be chalked up to human error vs. poor, semi-automated QA.

Found the Boeing executive.

Tech L7 who can only program Python but thinks they could be the next Boeing CEO.

There were only 2 possible causes of the incident, either the bolts had been replaced with bolts made from an inappropriate material, so they broke, or the bolts had not been assembled correctly, and they became loose.

It appears that the latter is what happened.

Perhaps those who did the assembly of the doors at Boeing did not use the right kind of washers that are needed to prevent the unscrewing of the bolts, or they did not apply the correct torque to the bolts.

It is extremely surprising if such trivial errors can happen during the assembly of an aircraft.
