Clifford Stone was a former U.S. Army sergeant who became widely known in UFO and extraterrestrial research circles for his claims of firsthand involvement in UFO crash retrievals and contact with non-human entities while serving in the military. His story is one of the most controversial in modern UFO lore.
Here’s a breakdown of who he was and what he claimed:
Military Background
-
Full Name: Sgt. Clifford Stone
-
Service: United States Army (active duty from the 1960s through the 1980s)
-
Role: Officially served as a clerk and typist, but he claimed he was also part of a classified crash retrieval team.
-
Retirement: He left the Army in the late 1980s.
While his official record shows a standard military career, Stone maintained that he had unofficial assignments dealing with UFO phenomena under a covert program.
His UFO and “Crash Retrieval” Claims
Stone stated that during his service he was part of a secret unit whose job was to recover crashed extraterrestrial craft and bodies of non-human entities.
He claimed:
-
He participated in dozens of recovery missions around the world.
-
He encountered living extraterrestrials during at least one of these operations.
-
The U.S. government had cataloged 57 distinct alien species, some of which look very human-like.
-
Much of this information was deeply compartmentalized, meaning very few in the government knew the full scope of it.
He described himself as an “intuitive communicator”, claiming the military selected him for these missions because of his natural ability to telepathically communicate with non-human beings.
After retiring, Clifford Stone became a public figure in the UFO disclosure movement. He spoke at UFO conferences and Disclosure Project events, including Dr. Steven Greer’s 2001 National Press Club event, where ex-military and government insiders testified about alleged UFO secrecy. He gave numerous interviews and lectures, often insisting that the U.S. government possessed technology derived from alien craft. He authored books and shared thousands of Freedom of Information Act (FOIA) documents, claiming they proved official interest in UFOs (though critics note these papers don’t confirm alien involvement).
Clifford Stone continued to speak publicly into the 2010s, often emphasizing that he wanted transparency and truth about UFOs.
He passed away in February 2021.
