Project 10073 Record Card — Montevideo, Uruguay, January 1959

This document consists of a Project 10073 record card and associated correspondence from the Centro de Investigación de Objetos Voladores Inidentificados (C.I.O.V.I.) in Uruguay, dated January 1959. The primary subject is a UAP sighting reported by an 18-year-old student in the Minas region of the Lavalleja Department. The witness described observing a single, metallic, oval-shaped object that appeared greenish-yellow before changing to orange. The object was estimated to be at an altitude between 2,000 and 5,000 meters, moving in a curved trajectory while rotating on its axis. The witness reported that the object made a sound similar to a locomotive. The sighting occurred during stormy weather conditions. The C.I.O.V.I. organization, in its correspondence to the Uruguayan Air Force Intelligence Service, stated that the case was being submitted for inventory purposes only, as it lacked the necessary elements—such as verified observer reliability and sufficient data—to justify a formal investigation. The record card explicitly concludes that there was 'insufficient data for evaluation.' The document includes a detailed observation form filled out by the witness, which notes that other witnesses also observed the phenomenon, though they disagreed on the color. The witness provided their identification and electoral card number (G.A.A. 3426) as part of the report. The file is marked with the reference number 1253/58.
