Case Sioani 091, UFO sighting in São Paulo

Summary

In 1971, a Brazilian pilot reported an unusual aerial phenomenon near São Paulo. The SIOANI 091 document, part of an official archive from the Brazilian Air Force, details this case with surprising precision for the era. The observer, Jorge Gabriel Ward, described an unidentified object with lights moving in an unusual manner. Although the report includes detailed questions about atmospheric conditions, the observer's physical state, and technical descriptions, many sections remain incomplete or illegible. The case stands out for its formal structure and the institutional interest in investigating unconventional aerial phenomena.

The document reflects the methodological rigor of the Brazilian Air Force at the time, with detailed questions about the object's appearance, movement, and any environmental impact. Despite missing information in some parts, the SIOANI 091 case is a valuable testimony of the official approach to UFO reports in the 1970s. This type of record, though incomplete, is essential for understanding how authorities dealt with these phenomena and what categories they used to analyze them.
