If they were demon manifestations, their reason for being, is deception. They try, among other things, to divert attention away from God, to beings from other planets.
I was an air traffic controller. I was told by the higher ups, that even if I saw something, that I really didnt see anything. Too much paperwork. Once I saw two lights in the night sky. It scared one of my subordinates, but it was just a tweet, at about 10,000 feet, with his landing lights on.
Knowing what I know about radar, unless an aircraft is using its transponder, I never hardly ever looked at raw targets. I dont know if demon manifestations show up on radar, but nothing would surprise me. I doubt any would be squawking an IFF/SIF code, however.
Many years ago, around 1958, I was a young sailor stationed at an Naval air station on the east coast. I was not in an aviation rating but I enjoyed talking and learning all I could about Navy aviation.
One evening, during a conversation with an air control person, he casually mentioned that they had tracked an object going north at around 4,000 mph and that it had made a definite course change indicating that it was a controlled flight. He did not say what altitude.
In 1958 that speed was unheard of.
Interesting. I have always thought that would be an intense job.
Now that I remember, he showed a video taken of an object that was flying near a plane. Maybe that has been debunked, but the pilot seemed credible.
I’ve been in Revelation lately so it’s certainly clear that satanic deception beyond imagination is ahead.
