Somebody just posted (and deleted?) an answer to your post with a video of the night sky and a man tracking satellites as they disappear at the terminator. That guy was telling “this is cloak tech” whereas he doesn’t even understand that a satellite is bright only when lit up with the sun. Satellites you see crossing the sky can, and will, disappear mid-sky because they get into the shaded part of the earth. This is why you can’t see LEO sats long after the sun go down, and brainless interpolation is why idiots like the poster of that video believe they see cloak tech.

I like your comment, except the last sentence. The guidelines ask to write civil comments, and I believe it even includes people that is not here.

The video is 15 minutes long and I get bored a. When does exactly the satellite "gets cloaked"? The second comment in YouTube links to https://earthsky.org/space/i-saw-a-flash-in-the-night-sky-wh... Is that a good explanation?

Yes that was not very subtle, sorry about that.

It might be iridium flares, although it looks like he got slow moving sats, so higher in altitude. Either way, they all look like that, fast straight moving lights, not pulsating like stars, not red/green like planes.

You can see the ISS very clearly when it passes above. It sometimes disappears mid-pass when it is late and the shadow of the earth is obscuring half your sky. You can also see the SpaceX sat train (60 sats in a straight line) passing by just after a launch. This will freak you out though, it looks like a straight comet trail moving half the sky in 1 min.
