No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Half as interesting just did a video on this
https://youtu.be/3i_RyiQ3-Ak?si=DRWUQw0FHnHRDsts
Short answers from the video: (but its a good video if you have the time)
I like your point #3 the most. We're at #$!@ 30,000 feet, you bastards!
Specifically about that third point, how long would it take to get into a "livable" range if you were free-falling? Like obviously hypoxia is a legit concern, but are you going to get out of that range quick enough to avoid real complications?
You'll survive for quite a while once you're below 6000 m. In free fall that would take you around 90 s, assuming a fall from 11000 m, and that it takes 200 m (5 s) of fall to reach terminal velocity of 200 km/h.
This is quite rough, but gives an appropriate order of magnitude. In those 90 s, you would be very likely to pass out and be guaranteed to get severe frost bite. We're talking major amputations levels of frost bite, as you would be moving at 200 km/h, exposed, in temperatures in the -50 C to -10 C range. I've seen people get frost bites moving at 40 km/h in -15 C for a couple of minutes with just a sliver of skin exposed.
So short answer: You might survive getting into the survivable range, but at the very least you will require intense and immediate medical attention upon landing. Seeing as there will be potentially a couple hundred people spread out over a large, possibly remote, area requiring this attention, it's unlikely that many, if any, would survive the ordeal, even if most people survived the initial 5000 m of fall into the survivable altitude range.
I have no idea what a livable height is, but it take about 3 minutes to hit the ground falling from that height (obviously there is a lot of error here depending on the exact person).
Also just being realistic those parachute are probably just going to be questionable bargin bulk buys. They'd be designed to be as cheap as possible while just barely passing legal standards. They never be maintained or inspected. And there's no way they support my 6'5" 300lbs ass as my frozen corps plummets to the earth below.
FAA is one of the better government agencies. In the US, they'd have to be tested and be shown to work on a regular basis in the same way that the emergency rafts and oxygen candles are tested.
