I went down the rabbit hole on this last night. I swear, every single video I have seen posted of this shit looks like regular airplanes. Except for the video claimed to be recent that was obviously a B-2 bomber and was filmed a couple years ago, those are definitely not normal airplanes; some moron posted it without sound, then someone else posted the original with sound and it sounded exactly like a low flying B-2 sounds (loud as hell).
I think the explanation is simple: most people do not look at the sky, some morons have started a panic, and now other morons are finally looking up instead of at their screens and seeing planes at night in a region with extremely busy skies. And probably some actual drones mixed in as well, hell our sheriff was flying one here in town last night looking for a robber.
