Incident Report: Unidentified Aerial Object Sighting in Votorantim and Sorocaba, May 1974

This collection of documents details a series of sightings of an unidentified aerial object (UAP) by workers at the Santa Helena cement factory in Votorantim, Brazil, occurring on the night of May 23-24, 1974. The primary witness, Rafael Fernandes dos Santos, an excavator operator, reported seeing a circular object with green, yellow, and red lights hovering over the quarry. He described the object as emitting a turbine-like humming sound, though it was silent at times. The object reportedly performed complex maneuvers, including hovering, oscillating, and accelerating, and was observed by several other workers, including Jaime Belizário, Salvador Pinto da Silva, Francisco Vieira, and Mauro Bulgari. The witnesses noted that the object appeared to be about 100 meters above the ground and moved in the direction of Votorantim before returning to hover over the quarry. The incident caused a partial work stoppage at the factory due to the alarm of the employees. The local police in Votorantim conducted formal interviews with the witnesses, documenting their accounts in official statements. The Delegacia Seccional de Polícia de Sorocaba subsequently forwarded these reports to the 4th Air Zone Command. The file also includes correspondence from the Canadian U.F.O. Research (C.U.F.O.R.) organization, which inquired about a separate, unrelated incident involving a death in Aracariguama, suggesting a broader interest in UAP phenomena in Brazil at the time. Additionally, the file contains classified reports from the Brazilian military intelligence agencies, CISA and the Army Cabinet (CIE), regarding a separate sighting in Belo Horizonte on April 7, 1974, which included detailed witness interviews and mapping of the object's trajectory. These documents collectively illustrate the formal administrative and military response to UAP reports in Brazil during the mid-1970s.
