I know what you're saying! Clearly the vast majority of these drone sightings seem to be regular aircraft.
Some do not seem to be, although my skepticism is high because I have seen a lot of faked UFO videos over the years and faking points of light in the night sky is like, the easiest thing to fake in a fake video/photo.
While I think this is unlikely, we could imagine that whoever is doing shady drone stuff might want to actually observe some basic safety rules, ridiculous as that sounds.
Suppose for a second that these drones are a "flex" from China/Russia/whoever. Causing a midair collision with an aircraft because they're running dark, or risking the chance of that because they're running dark, is a lot more serious than just flying some drones.
And if it's aliens, hey, maybe they're just trying to... uh, fit in by mimicing our airplanes' safety lights? =)
Would these drones be running FAA-standard navigation lights and a transponder? Because that seems to be the case for most of these drone spottings :)
