The man-made UFO disinformation is really catching up speed.

So first, the USA hides all information it has about UFO secret, than waits for the millennium to arrive and then in an attempt to discredit all UFO sightings starts this campaign.

If you hear that the UFOs are man-made in documentaries etc, its because they are fine with the idea of you believing in this.

They never wanted to announce the existence of real UFOs, because it implied the USA Government wasn't really in control of what was going on in its airspace, planet, etc.

No tyrant that self-worships himself as the ruler of a planet wants its slaves to doubt its dominion over the world.

More importantly, by announcing the existence of aliens, or any crashed UFOs, would make it very difficult or nearly impossible for them to reverse engineer alien technology in order to gain further advantage over other nations.

But, man-made UFO do exists. It has become practically impossible to differentiate between the real thing and the man-made ones. They reverse engineered the man-made UFOs from the real ones that crashed in the late 1940s.
