This is an excellent piece in Gizmodo about the ongoing UFO saga.

What I find particularly interesting is the interview with Mark Pilkington, author of Mirage Men, which details Pentagon disinformation aimed at misleading the public into thinking the UFOs are extraterrestrial.

The article also mentions the hugely important phenomenon of the large triangular UFOs that have been observed at low altitude by numerous witnesses, including cops. The triangular, or delta-shape craft, were seen over the Hudson Valley and Belgium in the 1980s and 90s, Phoenix in 1997 and southern Illinois in 2000.

Of particular note, witnesses in the Illinois sightings said the object abruptly moved from location to location, instantly darting around the night sky. This indicates a startling propulsion breakthrough, one that could have major implications for space travel.

Anyway, let’s assume this object is one of several top-secret U.S. military platforms that includes the flying “Tic Tac” vehicle observed in 2004 by U.S. Navy pilots – advanced-propulsion weapons that have been developed entirely by Homo sapiens, the same species that has brought us a bevy of tech marvels over the centuries, from the pyramids to nukes, microchips and lasers to the Antikythera mechanism and Greek fire. No assist from space aliens required!

According to this “terrestrial hypothesis” for UFOs, the evolution of these vehicles began during the immediate postwar period and they have been kept under wraps since that time, all the while becoming more and more sophisticated and largely hidden from Congress, the executive branch and the public. This supposition presumes that the entire space-alien hypothesis is just a myth fed by popular culture and the Pentagon’s disinformation apparatus.

As to why the Pentagon would be flying these weapons over populated areas, perhaps it’s real-world training, a “living lab” to perfect tactics and to study how well they perform against state-of-the-art, white-world technologies like F-16s. There are various examples of military training exercises taking place over populated areas. This article in The War Zone documents one such exercise over Los Angeles: https://www.thedrive.com/the-war-zone/38753/those-mysterious-gray-helicopters-were-landing-on-multiple-downtown-la-rooftops-last-night

So, let’s assume the UFOs have never been about E.T. They have always been about the U.S. military. Based on witness testimony, it certainly appears that the Pentagon has achieved a propulsion breakthrough – or possibly a series of breakthroughs. However, the Pentagon can’t admit that it has antigravity because, well, then it would no longer be secret. It all makes perfect sense, in a convoluted kind of way.

I would argue that when you consider the pattern of UFO encounters going all the way back to 1947 that the U.S. has had some form of antigravity or field propulsion technology either in development or in operation since then. If this is true, then these systems have evolved entirely within the Pentagon’s “black budget,” which is beyond the scrutiny of public officials and the media.

At the same time, there appears to have been a considerable disinformation effort to make people think the UFOs are E.T. because as soon as you entangle the entire subject within the intellectual morass of space aliens you relegate the whole story to the fringe. Once you start talking about E.T. crashes and dead aliens, interdimensional beings, time travelers, and the Vatican’s in on the whole secret, the public and the media don’t take it seriously. The only people who do take it seriously are those who are already convinced that it’s extraterrestrials or are just making money off the E.T. hypothesis.

So, if this terrestrial hypothesis is correct – and the Pentagon does, indeed, have antigravity, this raises a whole host of follow-up questions and concerns, including:

• Do we have a shadow space program that runs parallel to NASA and the Space Force? If so, do we have military bases in deep space?
• When the SR-71 blackbird was retired in 1990, was it replaced with another, more advanced platform capable of reaching any destination in the world quickly and on short notice? Is that what these triangular craft are?  
• In addition to antigravity, have we developed a propulsion system that harnesses the Casimir effect? This might explain the incredible performance observed by police officers in southern Illinois in 2000. At least one of the officers said the ship darted from place to place, instantly leaping several miles at a time.
• If we have, indeed, developed such a propulsion system, have we gone interstellar?    

Of course, in exploring the terrestrial hypothesis there are many additional potential questions you could pose.
