The idea that mystery nefarious drone operators would be sending up things with blinking red and green navigation lights on them is patently absurd. As others have pointed out in this thread, there's a lot of more mundane explanations.
Also it can depend on what people consider nefarious. For a long time I noticed drone coverage over my area regularly at night, which how they were operating over a populated area would be illegal for a civilian. Eventually I figured it out to be law enforcement drones. It's perfectly legal for there to be cop drones but people might consider them nefarious and law enforcement has been taking a boiled frog approach to drone acceptance.
it seems the videos posted with blinking red and green navigation lights are actually not representative of the drone sightings authorities are investigating but instead represent a side effect of the mania with people posting videos of private aircrafts as everyone is looking up and trying to record the “drones” but doesn’t realize the aircraft have been there all along and first they are paying attention.
It could be some politicians are leveraging the situation to get stricter drone laws passed. It should be unnerving to all of us that any semi-intelligent person with a few thousand bucks could weaponize a drone and send it off to wreak havoc. I'm not a drone enthusiast, but it seems like the level of regulation and enforcement has fallen way behind the access to the technology.
Exceedingly unlikely in my opinion, I've seen pictures/videos of these mystery drones and they look exactly like commercial aircraft white, red and green navigation lights. Or the red and green lights you would see on the end of the arms on a COTS DJI/Autel/competitor type UAV.
