These shoot up or down from the sky and leave a trail of smoke. Are these meteors?

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.

Those are contrails caused by aircraft. Contrails come from one of two sources- either water vapor in the jet engine's exhaust (one of the products of combusting hyrdocarbons is water,) condensing into a stream of mini clouds.
The other source is caused by the flow of air over the surfaces of the plane. typically over the aerodynamic surfaces (though in the YF-23, it could have been caused by that valley between the engines,) What's happening here is there's water vapor in the humid air, and the dewpoint is such that, as the air flows around the wing- the air pressure changes, and if that pressure change is enough, it'll cause the humid air to momentarily drop below the dew point creating a stream of cloud.
If, any points to a contrail and says 'AH CHEM TRAIL' feel free to laugh at them. it's just water vapor that's been condensed into suspended water droplets.
(Re-Commenting, since my original comment got yeeted into the nether... sorry, this is in exact but it should at least have all the same information for posterity)
My brother has this completely redpilled friend. He's taken college level classes on aerodynamics and aerospace manufacturing (so have I). He's always pointing out the contrails and saying something about mind control or Bill Gates...
I always sarcastically ask him about what other medium would he expect them to be projecting the sky on. Gets him to shut up real quick. For an hour or so.... They really aren't that bright.
I've told one of them that if they really had a chemical that is undetectable and operates at such small doses, it would be much cheaper and easier just to have a few guys with a pickup truck dropping bags of it in the reservoirs.
Way easier to keep that under wraps than to deliver tons of it to all the world's airports and secretly load it onto all the planes.
I saw her wheels turning, but it didn't work.
Here. This will convince them:
There is another kind of trail left by planes that really are chemicals, though: Crop dusters.
Yeah. But that, like cloud seeding, isn’t what the conspiracy is about, and pretty self evident as they’re just above the crops they’re dusting.
We’ll add water drops for attacking wildfires on this list, too.
Although, technically…. Water is also a chemical…but let’s not confuse them.
