The Alien Who Walked Into the Pentagon — The Valiant Thor Encounter


Listen Later

In 1957, a man calling himself Valiant Thor reportedly appeared in Virginia, entered the Pentagon without identification, met U.S. military leaders, and even sat down with President Eisenhower and Richard Nixon.

His message: Stop nuclear weapons. Unite the planet. Join a higher interplanetary community.


He supposedly lived inside the Pentagon for three years, wore an indestructible suit, and claimed to come from Venus — not the surface, but a civilization beneath it. The story spread through UFO circles, contactee movements, Cold War anxieties, and eventually became a foundational piece of 1960s UFO mythology.


In this episode, Neal and Andrew break down:

  • Where the Valiant Thor legend came from
  • Why it became so influential
  • Whether the evidence holds up
  • The role of 1950s fear, religion, and UFO culture
  • The controversial evangelist who kept the story alive
  • And the big question: If Thor never existed, why has this story lasted nearly 70 years?

Stay to the end for the MTAS verdict:  Is the Valiant Thor encounter “mostly true,” or not?
