UFO sighted in Sao Paulo in 1973

Summary

In 1973, a UFO case was reported in Sao Paulo, Brazil, and officially documented by the Brazilian Air Force. This document, part of the SIOANI archive, describes a brief but clear observation of an unidentified object. According to the testimony, the UFO appeared as a "fish" with green and silver colors, an oval shape, and approximately two meters long. It was seen during the day at an unspecified altitude and remained visible for a few seconds before disappearing. The observer, a middle-aged woman, described the phenomenon in detail, though no sounds or contact with the crew were recorded. The observation was rated as "good" in terms of credibility, and the document includes information on weather conditions, the exact location, and a description of the surroundings. Despite the brevity of the event, this case is interesting due to the precision of the description and the geographic context.

The document also includes psychological and social data about the observer, such as marital status, habits, and educational level, which helps assess her reliability. Although no physical evidence or photographs were found, the testimony was considered valid and archived for future research. This case reflects the rigor with which the Brazilian Air Force recorded UFO sightings in the 1970s, a time when unexplained aerial phenomena were studied in several countries.
