I only know that objects that have no illumination of their own and are roughtly the size of office desks CANNOT BE SEEN from the alleged 280+ mile away they're claimed to be. Now, allegedly the newer ones are like 20 feet by 10 feet or so, but that's still tiny, and those ones are allegedly at 340+ miles away.
I defy anyone to put a desk up on a pedestal (so it's not obscured by "curvature") about 10 miles away on an extremely clear day and see it with the naked eye. Utter nonsense. Ah, but they have "solar panels". Yeah, right ... against miniscule in size for one thing at those distances and 2 ... uhm, mostly turned to FACE the sun, since that's what they're for ... and yet they're still visible to the naked eye.
Whatever "Star Link" actually is, it's most certainly not what they say it is. I suspect that it's some kind of holographic nonsense to be perfectly honest, and they're not even satelloons.
