I've seen it. It's kind of cool. 8 pale, silent dots in line moving across the sky for like 3 minutes.
I'm sure they've seen airplanes flying at night with brighter lights, and louder noises than what starlink produces, so I'm not sure how this is really a problem.
For what its worth planes generally avoid flying through designated dark sky areas.
globe.adsbexchange.com -> click the replay button, and then scrub to some random time after sunset in CA. Turn on flight tracks and set the speed to 100x to make the flights easier to identify.
Flights from major airlines coming from Alaska, Asia, and Hawaii seem to frequently fly directly over Catalina at night.
By that, do you mean they can't see the starlink satellites now with their eyes, despite the number of them? Or do you mean that before they didn't see anything and now it is a problem and they are seeing things with their naked eyes?
(They were arguably also one of the most interesting and inspiring phenomena on the sky, too. I miss them.)
