Project 10073 Record Card — Uruguay, June 1957

This document comprises a Project 10073 record card and an accompanying investigation report from the Uruguayan organization CIOVI (Centro de Investigación de Objetos Voladores Inidentificados). The report details a sighting in June 1957 by a 19-year-old female witness, identified as Sta. Martinez, in Campanero, Department of Lavalleja, Uruguay. The witness observed a single, solid, round, and squashed-shaped object that appeared metallic and blue-grey in color. The object was described as brilliant and moved at a uniform speed in a straight line from South to North. A notable feature of the sighting was the sound, which the witness described as a long, high-pitched whistle or 'chiflido'. The witness also reported that the glass windows of her house vibrated during the event. The investigation report contextualizes this sighting by comparing it to two other incidents: one in Canelones involving Sra. Amalia Lacondeguy de Lescoumes, who reported a high-frequency vibration, and another by Juan Ramón Mora, who described a sound similar to the humming of a bee. The CIOVI investigators concluded that the object was a 'flying saucer'. The record card itself notes that the duration of the sighting was not reported and that there was insufficient data for a definitive evaluation, though the accompanying narrative is more conclusive. The document includes a map of Uruguay and a detailed observation form filled out by the witness, which confirms the lack of radar contact and the absence of physical traces or physiological effects on the witness.
