Amazing Stories, May 1958

This document is a UFO sighting report form (ATIC Form 329, dated September 26, 1952) and investigation records from Uruguay's Centro de Investigación de Objetos Voladores Inidentificados (C.I.O.V.I.). The primary case documented concerns an observation on May 20, 1968, near Sarandí del Yí (Florida), reported by witness Martín Bechorrigaray and corroborated by witnesses Moccia and Martínez. The object appeared as a white trail or contrail moving at slow velocity at high altitude, eventually disappearing without trace. The form includes extensive investigative questions addressing the phenomenon's characteristics, duration (noted as over 95 minutes in a related case comparison), cylindrical shape, stationary periods, low humming noise, color properties, proximity to military installations, electrical disturbances, and physical effects on witnesses. The investigation concluded "Insufficient data for Evaluation" regarding the object's true nature.
