Apparently, it is an optional emergency exit that was factory sealed since that particular cabin configuration doesn't require emergency exit there.

I guess, this might be the best place for this. Not related to MCAS, but it is a 737 Max in question. On January 5 2024 Alaska Airlines Flight 1282 suffered a midflight fuselage failure (altitude of 16 000 ft). A decent chunk blew out. Luckily, no fatalities. The aircraft in question is brand new, having first flown on October 15 2023. FAA grounded 171 737 MAX 9 (including all 65 in Alaska Airlines fleet). https://www.reuters.com/business/aerospace-defense/us-safety-board-investigating-alaska-airlines-boeing-737-max-9-emergency-landing-2024-01-06/ This is in addition to this bit from December 28 2023 "Under consultation with the FAA, Boeing has issued a Multi-Operator Message (MOM), urging operators of newer single-aisle airplanes to inspect specific tie rods that control rudder movement for possible loose hardware." https://www.faa.gov/newsroom/faa-closely-monitoring-inspections-boeing-737-max-airplanes

Did space shuttle have those? Was the full configuration ever static tested (two SRBs + orbiter with the big boy tank)?

No, they don't. Seriously. They don't owe us any info whatsoever. If there are third parties out there that do have a legitimate claim to this data, we don't see them complaining.

So much this. No only there already is a vacuum on Mars (or near enough for this discussion), so you don't need the tubes, but in order for a train (or any mass transit system) to make sense, you need at least two locations far apart with heavy demand. I don't see Mars having two colonies any time soon, let alone them being big enough to need a high speed train connection between them.

Oh, I completely forgot. If you guys want radio only for music and not news, have everybody write down suggestions on songs, albums, performers and assemble a mix which you then put on an MP3 player. An old iPod or even a cheap Aliexpress one will do just fine. As for multiple radios, there are FM transmitters that may help (check if they are legal in your area).

Consider getting a better radio. Alledgedly car radios have significantly better reception than home/office stuff since they need to operate in electronically noisy environment.

What's the difference between the two? Anyway, pufferfish.

Waiting for the golden record-like analysis of all the markings.

In fiction, sure. Just have all the uranium mined by a civilisation long gone (or don't explain it at all). In reality? What would be the mechanism that prevents U from getting in that particular part of accretion disk which will eventually form the planet, but be present in another part of that same cloud so it can be fount elsewhere in the system?

Moon (2009) explores why you need human presence.

Such deflection may be trivial, depending on how much time until impact.

We already have engines with ISP measured in hours. DART mission used NEXT-C ion thruster which has ISP of 4190 s, or 1,16 hours. We've had that for quite some time, and they work in atmosphere just fine. Sprint missile.

Booster disassembled itself just as the engines turned off. There was a bit of a lack of symmetry in regards to which engines were firing at boostback, but the orientation looked roughly ok-ish. I wonder if those things are related

Here's a real world example from personal experience with a 60W fiber laser that can cut through metal. If I want to cut through a 1 mm plate (which is a very deep cut compared to the size of the laser dot, and near the limit of the machine I have) I get better results if I wobble the laser beam; meaning a straight line is actually a spiral (think tiny circular motion combined with linear movement). This makes the kerf (width of cut) significantly wider than the size of the laser dot which makes evacuation of ablated material much more efficient. Otherwise the evaporated / molten and exploding material just deposits back on the previously cut side walls and the cut partially closes again. Wider channel prevents this depositing and recutting since the material can be thrown out.

That doesn't work, for the same reason why you can't pick up yourself off the ground.

When you say no fuel, do you mean no reaction mass? So what does it push against? Ground? You can't get to orbit by only pushing up. You need sideways speed.

Your average tv watching individual doesn't watch rocket launches now; why would they suddenly become interested after becoming a filler between ads for ambulance chasing lawyers, sleeping pills and hemorrhoid creams?

That timeline would have been too optimistic even if they had an actual functioning article. My vote for is Theranos scenario.

You most certainly can not. Your lungs would need to contain one atmosphere of pressure difference. The limit on human physiology is about one tenth of that, something you can test by trying to blow a column of water up a hose and see how high you can make it go. Your target is 10 meters; I'd be surprised if you can manage more than one. And don't call me Shirley.

Water boiling from exposure to vacuum does not make it feel hot. It actualy cools down (which is the source of comically fast freezing in vacuum trope in fiction), but as you noted a lot slower than depicted in the movie. It is possible to freeze water by exposing it to vacuum, but it takes time. Exposure to vacuum leads to a quick loss of consciousness (in about 15 seconds, or the time it takes for the deoxygenated blood in lungs to reach the brain). Death is quick to follow.

You can't expect us to not only keep track of all your previous ideas but to divine which ones you want to apply to new threads without mentioning them. Add to your existing thread that includes the concepts you want to include, so we can play along.

More than two weeks of thumb twiddling on some barren backwater planet (likely with no water), just so you charge up a few hours of propulsion? That's gonna get boring very soon. What is so magical about 1g threshold, that 0,98 g does nothing?

If you want to blatantly break laws of physics and make perpetuum mobile in your fiction possible, go for it. Just keep in mind that everything we currently know about universe says this can't work in reality.
