I read when the CIA was moving documents into storage some weren’t destroyed as they were put in the wrong place. So I’m sure anything that’s taking place now will be “destroyed” lol.
I’m sure there are things that go on that very very few people know about. The SR71 Blackbird was developed in the 60’s and 70’s and set records for speed/distance that have yet to be broken today, I’m sure only because the public isn’t made aware of what we have now.
I agree with you though on the conspiracy theorists that can’t back anything up and come up with some wild ideas and stories, and all these actors and media are just story tellers.
