Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Japan flight diverted to Seattle after man tried opening door mid-air (www.bbc.com)

A Japanese plane headed from Tokyo to Texas had to make an emergency landing after a passenger tried to open one of its doors during the flight.

All Nippon Airways (ANA) Flight 114 was diverted to Seattle hours after taking off on Saturday "due to an unruly passenger", the airline said.

Port of Seattle police told media they had been notified of a man who "attempted to open exit doors during the flight".

The man, who was not identified, was "having a medical crisis" and had to be restrained by other passengers and flight crew, police said.

... If you are at a crusing altitude of say angels 30, and you suddenly dump or otherwise rapidly lose cabin pressure... in addition to hypoxia, wouldn't this also be screamingly painful for everyone's eardrums, potentially bursting some of them?

Screamingly painful? Bursting eardrums? Probably not.

Atmospheric pressure at 30,000 feet is about 4.3psia. Aircraft cabins are pressurized to about 12psia. There will be about an 8psig difference when you lose pressurization.

To put that into perspective, diving to a depth of 20 feet is about 8.6psig relative to the surface. A sudden loss of pressure would be the equivalent of quickly rising from the bottom of a 20' pool.

For most, the pressure will equalize almost instantly.

Hrm.

I appreciate the actual psi numbers... maybe I just have particularly sensitive ears/vestibular system?

I've had painful ear popping experiences from going over mountain ranges in a car... maybe 'eardrum bursting' is a bit hysterical of me, but multiple times I've gone from sea level to between 5k and 10k feet, and when my ear pressure equalize, it is often quite painful for minutes.

"Pressure" is typical. "Discomfort" is typical. If you don't have an underlying condition like a sinus infection, "pain" is not typical. You might want to talk to an ENT.

I'm a balloon pilot. My ears will typically first equalize about 500 feet above ground level. I'll occasionally hear small little "farts" as the pressure changes, but I rarely feel anything more than slight pressure.

but multiple times I've gone from sea level to between 5k and 10k feet, and when my ear pressure equalize, it is often quite painful for minutes.

If your ears aren't equalizing until a 5k ascent, that's approximately 2psi pressure differential. I can see how that would be quite painful.

If your ears won't clear at all, yes, you'd have a problem. But, you're indicating your ears do eventually equalize. You won't experience more pain than what you already do.

Even though there is an 8psi difference between cabin and atmospheric pressure, your sinuses apparently start "leaking" at a 2psi differential; they won't build up an 8psi difference across your eardrums.

You might try a nasal/sinus decongestant before an ascent. Pseudoephedrine works best for me, but it tends to make my head swim. Oxymetazoline nasal spray works well, but I get terrible rebound congestion from it. Phenylephrine pills do nothing, but phenylephrine nasal spray ("4-Way") works very well for me.

Hey, entirely seriously, I do appreciate your breakdown and info, and even your suggestion to see an ENT... the last time I saw my primary care physician, they actually said they would refer me to one, given all the symptoms I've been having recently and over the past years.

Psuedoephedrine also makes me... basically near black out drunk, in terms of wooziness...

I will actually star/favorite this post here with all the other medications you mention so I can bring them up whenever my ENT refferal goes through.
