As this editorial in Cracked correctly observes, “there is a bit of a conspiracy to promote” the ET hypothesis.

Yeah, I agree! The entire conversation about UFOs has been dominated by people who are biased toward the ET hypothesis.

It’s time to give the terrestrial hypothesis some ink. There are various flavors if the terrestrial hypothesis, but the main tenet is this: UFOs are not piloted by space aliens but are of earthly construction.

The version of the terrestrial hypothesis that I subscribe to is that the Tic Tacs and other seemingly otherworldly UFOs encountered by U.S. Navy pilots are above-top-secret U.S. weapons platforms. The conspiracy goes all the way back to the 1940s, when there was an initial propulsion breakthrough. The Pentagon has managed to maintain this secret all the way to the present, with the initial propulsion breakthrough evolving into platforms that have astonishing performance capabilities.

The reason the Navy pilots are encountering these platforms is because they are also in training. After all, the sightings have occurred during Navy training missions and in waters reserved specifically for U.S. military training.

So, this particular version of the terrestrial hypothesis posits that it’s not ET. It was never ET.

That means Kenneth Arnold in 1947 saw U.S. military aircraft. The saucers over Washington, D.C., in 1952 were likely demonstrations ordered by President Harry Truman to verify superiority over state-of-the-art fighter jets. Truman had ordered a similar demonstration of the flying wing earlier in his career. I propose that the reason there were two UFO episodes over the White House in 1952 — one week apart — was that Truman wasn’t satisfied after the first demonstration. He wanted to see a more direct interaction with fighter interceptors.

The ET hypothesis is perfectly valid. I’m just saying that we need to consider an alternative. Certainly, the public isn’t being well-served when you have a group of people who are fully ensconced in the ET hypothesis running the show.
