Clifford Stone

Military Service and Cover Operations

Clifford Stone was a decorated Vietnam combat veteran and Sergeant 1st Class in the U.S. Army who served from 1969 to 1990—a total of 22 years of active military service. Officially, Stone held a secret clearance with nuclear assurity and was assigned to an NBC (Nuclear, Biological, Chemical) Team, ostensibly tasked with retrieval and hazardous material abatement. However, Stone's account—corroborated through his public testimony and media appearances—suggests this assignment served as a cover for far more classified work: covert UFO crash retrieval operations.

Stone claims he was covertly assigned to elite recovery teams designated Project Moon Dust and Operation Blue Fly, compartmentalized black programs designed to locate, secure, and exploit the remnants of non-terrestrial craft and their occupants. These projects, he asserts, involved rapid-response field teams dispatched to sites of UFO incidents, where physical contact with downed extraterrestrial technology and biological entities occurred under strict operational security.

Alleged Crash Retrieval Operations and Alien Contact

Stone's testimony describes participation in recovery operations involving non-human craft and live extraterrestrial beings. He claims to have physically handled recovered materials and witnessed the interaction between military personnel and captured non-human intelligence. According to Stone's account, these operations resulted in the collection of biological specimens—categorized by the military as Extraterrestrial Biological Entities (EBEs)—of which a high-ranking officer allegedly allowed him to review a classified manual approximately three inches thick that catalogued 57 distinct species or types of humanoid alien beings known to the U.S. government.

Moreover, Stone makes an extraordinary claim: since childhood, he has maintained ongoing telepathic contact with a humanoid mantis-like being named Korona, whom he describes as having studied human emotion and psychology. This lifelong alien interaction, presented alongside his military testimony, forms a controversial but consistent element of his disclosure narrative. Stone has been remarkably articulate and consistent in recounting these claims across multiple decades of interviews and public appearances, never significantly altering core details despite intense scrutiny.

The 2001 Disclosure Project Testimony

Stone's most significant public moment came on May 9, 2001, when Dr. Steven Greer's Disclosure Project held a landmark press conference at the National Press Club in Washington, D.C. Over twenty military, intelligence, government, corporate, and scientific witnesses came forward that day, with Stone among the most prominent voices. He publicly detailed his alleged involvement in retrieval operations, his knowledge of multiple non-human species, and his willingness to testify before Congress if called upon. This moment positioned Stone as a significant figure in the modern UFO disclosure movement, lending his military credentials and decades-long consistency to the broader witness testimony framework.

Following the Disclosure Project, Stone leveraged his platform for continued advocacy, participating in documentaries, radio interviews (notably Coast to Coast AM), and publishing his autobiography, Eyes Only: The Story of Clifford Stone and UFO Crash Retrievals (co-authored with photojournalist and UFO researcher Paola Leopizzi Harris). The book expands on his military experiences while maintaining the same core claims and adding personal reflections on his lifelong alien contact.

Alien Species Classification and Legacy

Stone's detailed descriptions of alleged non-human beings have become reference material in UFO research circles. According to his testimony, the 57 catalogued species fall loosely into recognizable types: the small, large-eyed Grays familiar from abduction literature; the tall, blonde "Nordic" humanoids often reported in contact cases; scaled, reptilian beings capable of shapeshifting; and insectoid or mantis-like entities such as Korona. His claims about systematic government cataloging of alien species have influenced contemporary ufology and provided a framework through which other witnesses interpret their encounters.

Stone passed away on February 10, 2021, but his testimony remains cited in disclosure advocacy and serious UFO research. Whether viewed as a credible whistleblower or a sincere believer in misinterpreted events, his consistent narrative, military background, and participation in the Disclosure Project have secured him a place in the contemporary UFO canon.
