🇧🇷 Fuerza Aérea (Operação Prato)
In 1964, a Brazilian officer reported a UFO sighting in the city of Lins, São Paulo state. The document, part of the SIOANI archive of the Brazilian Air Force, contains detailed information about the witness, who was a 32-year-old captain with studies at the Military Academy. Although the report is partially illegible due to digitization errors, it mentions that the event occurred during the day with normal weather conditions. The officer described a luminous, moving craft with an unknown shape, though no further details about its appearance or behavior are specified.
The case includes psychological and social data about the witness, indicating he was a married man with two children, a practicing Catholic, and a smoker. No physical or emotional effects are mentioned at the time of the observation, and no physical evidence was recorded at the location. Despite the lack of clarity in some parts of the document, the Sioani 066 case is an example of how the Brazilian Air Force documented UFO sightings in the 1960s, with a methodological approach albeit limited by the technology and resources of the time.
