400MPH with an open window plausibly causes some loud noise due to turbulent flow across the opening. The turbofan engines are also reasonably close to the opening and ground crew wear hearing protection to mitigate the effects of the noise.

My assumption was that the air pressure at that height is low enough to not be loud. Yeah it’s moving fast but there isn’t much of it. Different story on the ground.

That's a good thought. Initially the density is pretty normal and I'm sure there's a loud sound, but once pressure drops the air wouldn't transmit as much sound.

I don't see enough detail to really know how high they fly once the depressurization happens. I'm guessing that, if possible, they descend to an altitude where the supplementary oxygen is not critical for preserving life so the loudness could go back up. I couldn't find if there's a "typically safe" maximum altitude that is used in depressurization or it's situational.

Probably someone with better flightradar knowledge could figure out the altitude with time.

In the US, tech sucks all the oxygen out of the room (no pun intended). When so much top talent is locked up by big tech, who's left to design planes at Boeing, write software for GM, run for office?

This is nonsense in my opinion. SpaceX exists and did a lot of work with young engineers.

The problem isn't the engineers but the management. There are plenty of smart and hard working people in the US.

Its ridiculous to believe that GM is fundamentally unable to recruit software people. Tesla did it just fine, as a small company with less money. Its rather management that systematically for 30+ years has considered software to be unnecessary and pushed it as far down the supply chain as they could.

They’re building like one of these a day, mistakes get made. There’s nothing comparable to this assembly complexity in the computer world.

Except, you know, this thing called the Airbus A320 NEO. You know the thing that is more modern and produced at a higher rate. Somehow that doesn't seem to have doors falling of. So your statement is objectively wrong.

not much choice. Boeing is practically the only US manufacturer of widebody passenger jets and enjoys a privileged position as such. there is literally no other American competition for passenger air. Alternatives include the Chinese Comac 929, Sukhoi SSJ100, or A320 from Airbus. the first two are non-starters as most north american politicians are furiously opposed to the idea of carriers so much as looking at chine…

Unreal. Do people not go deaf from the sound of the air coming into the exposed fuselage like that? I would have thought they'd be covering their ears or something.

It's not so bad. Used to be a jumpmaster in the 82nd Airborne, where part of the job was to stick your head out of the side of the open door of a C141 while in flight to check for issues, towed jumpers, etc. It's loud, but survivable. You can hear yelling over it. Of course we were going much slower...

Honestly this might lead to another 737 Max grounding, which will shoot up the cost of airfare. At this point, the 737 Max seems cursed.

But was that door specific to the max? I would assume previous generations of B737 had the exact same door. It seems to me that this is more an indictment of Boeing's manufacturing than a design flaw specific to the max (well, we will see what actually caused it). If that's the case, this would curse all boeing models.

I don't think we know that yet. Yes, I have seen many reports that the Max has the "exact same door" as the 737-900, but how confident are we that there wasn't some cost-cutting or "simplification" measure done on newer models, or a change to a cheaper subcontractor building a crucial part, or whatever? There's enough complexity there that I think there could be significant differences while still theoretically staying within the "same design."

For the past two months, I have been avoiding 4 737max flights already. This is to the extent that one of them was to transit for 10 hours (without max), compared to a 2-hour convenient layover with 737max. I guess this will stay as my personal rule of thumb for the foreseeable future.

If we “assume” the eight hour distance is “life lost” and based on your age and average life expectancy, I wonder what the mathematical actuarial tables say.

I am not flying airlines that buy this crap airplane anymore.

Is there a list of airlines with MAX? I seriously don't want to fly in this death machine ever.

I'd recommend searching Google Flights with the "Legrooms for Google Flights" Chrome extension. Not only does it visibly list each aircraft type in the list of search results, but it also shows you how many inches of legroom each one has. One of the most useful Chrome extensions, IMO.

Me not spending a flight will have zero effect on Boeing. The FAA threatening to ground their planes will however get their attention. The FAA actually do quite a good job and if anything are maybe a bit over the top in enforcing saftey given that for most people there is near zero risk of dying in a plane crash compared to a lot of stuff that people do die regularly from.

One vote won't make a difference either, should people not vote? I'm not saying the FAA shouldn't also intervene, I'm simply pointing out that consumers almost always seem to ignore their own power in the situation. What you're describing feels much like a tragedy of the commons problem. If I chose not to fly everyone else still will and I'll be left driving around like a schmuck. I might as well fly too, and when I'…

> One vote won't make a difference either, should people not vote?

Basically, yes. Voting changes you way more than it ever changes the world, and introspection about that is worth considering.
