This was the (regular) rear door that Alaska effectively papers over.

Even if that is the case, it shouldnt been an issue. The DC10 problem was due to insufficient safety mechanism that allowed for crew to unknowingly close the door without engaging the safety lock.

Here's the safety mechanism for this door.[1]

They are still competing defence contracts with Lockheed, General Dynamics and Northrop.

For small aircraft. Not for major transports or tankers.

You mean fighters and drones? Which are arguably quite more expensive than the transports or tankers

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.

You're spending an extra 8 hours to marginally (at best) improve safety? I'd be willing to bet good money that you partake in wildly more risky activity (such as driving or even walking down the street). This feels almost like virtue signaling without it being virtue signaling.

It's called psychology breh

Why do people with no insight write walls of text on things they don't understand?

It’s rather ironic that by claiming their comment lacks credibility without including any counterpoints it makes your comment itself lack credibility too.

He keeps using "widebody" for narrow body planes. He lies about Boeing having anything to do with Airbus' foundation.

It's like an LLM hallucinating.

The receivers for LiveATC and the like are frequently somewhat compromised in terms of quality and location. This can cause poor quality reception depending on the location and distance away of the transmitter. The radios and antennas on both the aircraft and for ATC are not only of much higher quality but are also positioned as perfectly as possible so as to maximize Tx/Rx performance. All that to say, the pilots an…

Not long ago I took a short trip in a small Cessna (I think it was a 152). The audio quality in the headphones wasn't any better than what I hear on those ATC YouTube channels. I didn't understand a word of it (well, that's not quite true, I understood some words here and there; not nearly enough to be able to safely fly). A Cessna 152 is not an airliner, obviously, but I would think audio quality shouldn't differ al…

N of 1, etc. etc.

The 152 could have had a 40 year old radio or a crappy antenna. Who knows. As you pointed out - that 152 is subject to a lot less maintenance scrutiny than commercial airliners are.

The other thing that plays in here is that ATC language is very highly standardized. In any specific phase of flight, the pilot will generally know what to expect next from ATC. This allows them to discern instructions (and read them back for verification) even if the signal is weak. In situations like these, ATC may seem completely unintelligible to people not used to ATC language and patterns.

> We tried the approach you proposed in the past and it didnt work. You work at Boeing or aircraft safety regulator or something? Can you elaborate on what exactly you've done?

No, bad case of language barrier. Thanks for asking for clarification, its an equally unpleasant misunderstanding as people feeling insulted by the use of the generic you.

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.

Why is it important for everyone to cast a single vote that itself won't make a difference, but unimportant for one yo choose not to partake in an industry that they either disagree with or distrust?

If one vite is worth casting simply fr the fact that it can help a person think more deeply about issues that matter to them, certainly the same could be said for how they choose to spend their money as well.

They are building the Boeing KC-46 Pegasus. That is the big refueler and they are gone build 100s of them in the coming years.

They is very much competing in lots of different competition for lots things.

Unfortunately corporations are not democracies, so no matter what happens, they can ignore our 'vote' when we use dollars. Spending or not spending money does not compel any company to do anything. So, the comparison is not valid.

Companies are entirely driven by money. If one person chooses not to patronize the business it probably won't change anything. But ehst if a hundred do? Or a hundred thousand?

Agree or disagree with the politics behind it, Budweiser was absolutely rocked by a large enough number of customers deciding to no longer buy their product.

The comparison is absolutely valid from where I sit. One vote or one customs makes little to no difference. Enough people raising their voice, though, can fundamentally shake the system.

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.

I found this video of the cockpit communications and it looks like they quickly go to 10,000 feet then down to 7,000 feet.
