Brazil has made a significant move in the global UFO conversation.
The country’s National Archives now hosts a major OVNI/UFO collection through the SIAN platform, with nearly 900 documented cases reportedly spanning from 1952 to 2023. The material includes witness reports, pilot statements, drawings, photographs, audio, clippings, and other records tied to decades of unidentified aerial phenomena in Brazilian airspace.
As we know, Brazil is not a minor footnote in UFO history. Cases like Operation Prato, the 1986 “Night of the UFOs,” and other longstanding Brazilian incidents have made the country one of the most important regions in the world for serious UAP research.
A national government has preserved and opened a large body of raw historical material for researchers, journalists, and the public to examine directly.
At a time when many countries still treat this subject with excessive secrecy or ridicule, Brazil’s archive represents the opposite approach: document it, preserve it, and let people study the data for themselves.
That is what transparency should look like.
Sources note: Brazil’s National Archive confirms the OVNI collection is held by the Arquivo Nacional and accessible via SIAN, while Brazilian reporting describes the current archive as 893 cases from 1952–2023.
