This all fascinates me so much. I've been into this since that pilot went on Rogan a year or two ago and explained what he saw and everything he'd heard from other aviators.
I believe these things are real (not sure how to NOT conclude that at this point) and I don't believe any nation has that kind of technology, which to me means it HAS to be something created and used by some other intelligent lifeform somewhere else. I know that sounds kind of bonkers, but it really isn't. It seemed bonkers to uncontacted tribes in the Amazon when metal birds flew over them and took their pictures, doesn't mean it wasn't plausible once they recognized that they share existence with others far beyond their level of technological/scientific ability.
So, if I'm right and these things are from somewhere else, what, I wonder, are they doing? Is this basically an anthropological study? I don't doubt that these things could remain much more covert, so are they starting to put themselves out there to test/record how we react to them?
