I think Boeing should rethink their strategy. How are their Stockprices not at the bottom of the ocean yet? Cutting so many corners and risking so many lifes should not be legal. This should definitely be prosecuted. Either ban all the current executives or ban the planes.

Holy dick bags Batman. Cold environment testing is normal stuff. Coupled with cycle testing, and this shit ain't supposed to happen.
Cold environment testing? Isn't it like -40°C to -80°C at cruising altitude anyways?
Yes, and we have machines to do these things. Ours could easily fit 4 flight computers for a 4, 8, 12 or 24 hour test at -70C to something crazy like 50C
... so your machine could probably cool my GPU nicely is what you are saying ...
Yes. And it could change the temperature very quickly too. Unfortunately I can't remember how fast.
Ohh, rapid tem changes testing too, nice, probably with some active heat transfer system (... I mean a fan).
Specialised machines/tools/machine-tools are great to nerd out for a bit.
Like I said, I didn't appreciate how cool it was at the time. I was also paid a third of what I make now, that might have something to do with it.
when I was a kid, my dad worked at Lockheed... they had the coolest Take your Kid to Work Day. The basement was where the fun was- specifically the prototype testing lab with the 50 pound hammer that they were constantly knocking around mock ups of computer cabinets, the ginormous vibration table, and, yes, a cubical-sized refrigerator to do just that. The sound isolating chamber was also kinda cool... and spec sheets of the x33 demonstrator.
Thinking back on what I worked with, it was far more impressive than I realized at the time. We had 15 foot custom cables to connect the 125+ pin flight computer (four of them) to our test system. The test system also controlled the environment chamber, which had like 90 minute cycles from -70C to 50C but it also had a vibration table that has incredible acceleration. I believe it could reach near vacuum, and pressurize, I don't remember how much.
Cubicle size - yeah that checks out. The other thing I remember about ours that it was extremely tall. And blue
Well when you have a habit of not installing bolts it means anything on the plane can fail...
You’re probably right but can you explain your logic?
If you don't maintain your fleet, eventually they'll all fall out of the sky
Fleet maintenance is an airline responsibility.
The bolt situation was a Boeing responsibility.
These don’t really reflect on each other well.
The whole industry is structured to hold individuals accountable but not ownership... Think of the standards ATCs have to maintain. Pilot training hours. Why is that level of scrutiny not being applied to assets?
Yea, but that’s also an entirely different issue…
Inspecting equipment is a different issue than fleet maintenance or manufacturing QA?
Are you high or a dumbass?
Let’s see:
We started by talking about manufacturer QA vs fleet maintenance. I called out that those are different things handled by different people.
Then you went on to talk about individuals being held responsible instead of execs.
Now, we’re talking about inspecting equipment vs fleet maintenance vs manufacturer QA. Which I agree inspection and maintenance go hand in hand and are the responsibility of the airline, but they are still different.
You’re muddying things quite a bit.
Boeing isn’t to be blamed for poor maintenance. They don’t do that, the airline that owns the plane does. But Boeing is under significant scrutiny to we’re seeing all these stories about problems that old jets are having that can be chalked up to poor maintenance. That was my point to begin with.
It’s another conversation entirely to discuss who should be held accountable (see: execs) for these poor practices.
Not sure why we’re resorting to name calling but… ok.
