Declassified Argentine Documents Reveal 1991 Antarctic UFO Encounter Cover-Up
Recently declassified documents from Argentina's Ministry of Foreign Affairs have exposed a decades-long cover-up of a remarkable UFO encounter at the South Pole. The records, unsealed this year, provide official confirmation of eyewitness accounts from 1991, when military personnel and civilian researchers stationed in Antarctica detected and observed a large flying saucer hovering over their remote base.
The Witness Account
Miguel Amaya, a retired Argentine Air Force non-commissioned officer, first disclosed the incident to UFO investigators in the early 2000s. Amaya was stationed at General San Martín Base, a small scientific and military outpost on a tiny Antarctic island, during April 1991. At the onset of the polar night, when darkness persists for months, an alarm sounded on the station's riometer—a sophisticated device designed to measure changes in the upper atmosphere.
The equipment's three needle pens, which normally measure different heights of the ionosphere, began drawing identical patterns simultaneously. This synchronization was scientifically impossible under normal circumstances, as the needles should have displayed independent readings based on varying radio wave absorption at different atmospheric frequencies and altitudes.
Impossible Readings and Visual Sighting
According to Amaya, base personnel concluded that the anomalous readings could only have been caused by an external energy source equivalent to a nuclear aircraft carrier or a large city floating above Antarctica. The incident lasted approximately four and a half hours, consuming over 120 feet of recording paper as the needles moved so violently they repeatedly went off the charts.
Roughly sixteen hours after the initial readings, at around 10 PM local time, a radio operator from the Argentine Army reportedly witnessed the mysterious craft firsthand. While walking outside during a snowstorm, he observed "a huge circle of light" moving slowly and silently directly over the base before disappearing seaward. By the time he could alert others, the object had vanished.
Decades of Secrecy and Recent Disclosure
The 1991 incident remained shrouded in secrecy for over three decades, with Amaya claiming that he and his colleagues were ordered by superiors never to discuss what they had witnessed. The breakthrough came through persistent efforts by CEFORA, an Argentine civilian UFO research group, which petitioned for the records' release under the nation's public information law.
After more than fifteen years of advocacy by CEFORA director Andrea Simondini, the Ministry of Foreign Affairs confirmed that nine original paper rolls from the incident still exist and are stored at the Argentine Antarctic Institute. This marks the first time images proving unexplainable interference with the base's riometer have been publicly shared.
Broader Implications and Future Investigations
Simondini emphasized that this case represents just the beginning of verified disclosures under this method, raising expectations for further declassification of Antarctic UFO files. Meanwhile, in the United States, UFO disclosure efforts have intensified, with recent presidential directives ordering the release of all documents related to government investigations into unidentified aerial phenomena and extraterrestrial life.
Despite these developments, official U.S. positions maintain that no physical evidence proving the existence of aliens or non-human spacecraft has ever been found. The Argentine documents, however, provide compelling contemporary evidence that challenges conventional explanations and underscores the global nature of unexplained aerial phenomena investigations.
