I'm convinced that at the very center of it you have conventional but advanced top secret craft, counterintelligence and normal spy vs spy stuff. Everything else is a circus of lies, memes, folklore and psyops though.
Look up Paul Bennewitz[0]. I think that story is the closest we'll ever get to "the truth."
I’d argue these are a wholly distinct category of thing than the concepts associated with the words UAP/UFO. Surely there exist experimental aircraft, and that may be of interest to specialists in intelligence and military fields and may be worth an entry in some niche osint blog now and then. Other than that, anything that can be seriously said about uap/ufo belongs in psychology journals.
Just look at the New Jersey drone craze. How many reports were there of mysterious lights that turned out to be completely normal aircraft landings or whatever? It was basically mass psychosis of people who suddenly noticed the Up for the first time in their lives.
