This is such horseshit. Regardless of what you think of UFOs, of the hundreds of thousands of UFO sightings, many reported by military people, law enforcement and people trained to observe aircraft, hardly any of them resembled anything like a U2 spyplane.
Last time I checked, a U2 spyplane was not really capable of hovering motionless and then accelerating to the horizon in a moment. Nor were they gigantic triangular craft.
I don't think for a second that there are aliens from Ork involved with the UFO sightings that have been common for the last five millennia, but I doubt more than a handful were people who were seeing U2 spyplanes. Who knows fuck-all about what those UFOs really were or whether they were inside or outside the observers heads? But at the moment, I'm not prepared to believe a goddamn thing the CIA says about anything. In my opinion, they're a bigger threat to people's safety and sanity than practically any outside threat, including North Korea, Iran, Russia or Israel (who are all plenty bad),
Now, if you want to tell me that the abductions people have been reporting for the past 40 years are the CIA, I may buy that, because they are some sadistic motherfuckers who love putting things up peoples' asses, as we have learned from recent government leaks. Yeah, anal probes, mutilations, etc, that sounds just like the CIA's speed.
