Sighting Report of Antonio Gulin and Cassio Vendramini - Presidente Prudente, April 1969

This document contains official reports from the Brazilian Air Force's SIOANI (Sistema de Investigação de Objetos Aéreos Não Identificados) regarding a sighting in Presidente Prudente on April 26, 1969. Two local merchants, Antonio Gulin and Cassio Vendramini, reported observing an unidentified aerial phenomenon (OANI) at approximately 06:12 local time. Gulin, who was driving toward the city center, observed the object near the Tenis Clube. Vendramini, who was walking from his residence to his business, observed the same object from a different location in the city center. Both witnesses described the object as oval-shaped, reddish in color, and luminous. They reported that the object moved at an enormous speed, performed a vertical maneuver, and then disappeared. The report includes a hand-drawn sketch of the sighting location and mentions that the witnesses were considered credible. A postscript from the reporting officer notes that the local unit (SBDN) lacked the necessary CIONI questionnaire and requested that one be provided. The document also includes press clippings from the period, specifically from the newspaper 'Correio da Sorocabana', which covered the event and emphasized the credibility of the witnesses.
