Why would you be investigated? You have witnesses, unless you, your copilot and attendant all have a history of being drunk on the job. Reporting crap like that to the control tower isn’t going to end with a black bag over your head by some super secret government agency.

No that kind of investigation. But as it could be an aircraft that is not seen by the radar. We would have to declare for nacional security things. We were not completely sure as we were not landing in Argentina.

Can you explain "They were making like triangles" a bit more please?

Some satellites go bright and then dim, but the ones I have seen do that are usually solitary satellites, not in groups. There are some video examples here: https://earthsky.org/space/i-saw-a-flash-in-the-night-sky-what-is-it/

They were going bright and fading. Then when they appeared again they’d be in a triangle. Then one of them would go really bright then all dimmed again or fade and when they appear they were in another triangle. And so on. Sorry I can’t explain it better

Your post has been removed. For simple questions like these please use the weekly "All space question" thread pinned at the top of the subreddit.

I think you're saying: each of the lights would disappear and reappear in a different position, and those positions formed a triangle.

Is that right?

Right, also you could see them moving. Not all of them, like one while the other were dim. Then as you said they would reappear forming a triangle
