A cache of declassified Central Intelligence Agency records that were recently transferred to the Ronald Reagan Presidential Library has reignited debate over a little‑known Cold‑War‑era effort known as “Project Sigma.” According to the files, the program began in 1954 under the auspices of the covert “Majestic‑12” committee and was tasked with establishing a two‑way radio link with an extraterrestrial intelligence. The documents claim that, after years of trial transmissions, a binary signal sent from a ground station in New Mexico succeeded in eliciting a response in 1959, and that two alien beings were subsequently brought to a remote test site in the state in 1964.
The records, which were filed under the CIA’s “UFO/Extraterrestrial Phenomena” series, describe a series of covert operations that allegedly included the recovery of a downed craft near Roswell in 1947, its transport to a series of secret airfields in Nevada, and subsequent test‑flights by U.S. Air Force personnel. A memorandum dated 15 March 1964, signed by an officer identified only as “Director, Project Sigma,” notes that “the presence of non‑human technology has been confirmed, and further analysis is ongoing.” The same memo advises that “public disclosure would jeopardize national security and could incite mass hysteria,” recommending that the program’s existence remain classified indefinitely.
While the language of the files is striking, experts caution that the documents do not constitute proof of contact. Dr. Michael S. Miller, a historian of Cold‑War intelligence at the University of Texas, points out that the “Majestic‑12” group has long been regarded by scholars as a possible hoax or, at best, a highly secretive advisory panel with limited operational authority. “Even if the CIA did maintain a file on an alleged ‘Project Sigma,’ the absence of corroborating evidence—such as flight logs, engineering analyses, or testimony from participants—means we must treat these claims with considerable skepticism,” Miller said.
The revelations come at a moment when the U.S. government is under renewed pressure to be transparent about unidentified aerial phenomena (UAP). In 2023, the Office of the Director of National Intelligence released a report acknowledging 144 sightings that could not be readily explained, and Congress has mandated the establishment of a permanent UAP task force. Nevertheless, senior officials have repeatedly stressed that most of the data remain classified for national‑security reasons. A spokesperson for the Department of Defense, who declined to comment on the specific Reagan Library documents, said that “any historical records relating to past intelligence programs are subject to review, and we will release information in accordance with applicable laws and regulations.”
The new files have also drawn interest from former intelligence officers who recall a climate of secrecy surrounding UFO research during the 1950s and 1960s. “There was a genuine fear that the Soviet Union could exploit any knowledge of advanced technology, alien or otherwise,” recalled retired CIA analyst Linda H. Carpenter, who worked on aerospace surveillance. “Whether that fear was justified or not, the agencies involved often operated on a need‑to‑know basis, which left many questions unanswered for decades.” As the Reagan Library prepares to make the documents available to scholars, the broader public will likely continue to weigh the tantalizing language of the records against the lack of concrete, independently verifiable evidence.
