Project 10073 Record Card and Observation Report — Uruguay, May 1955

This document contains a Project 10073 record card and a detailed observation report (Ficha de Observación) from the Centro de Investigación de Objetos Voladores No Identificados (CIOVI) in Uruguay. The report details a sighting that occurred on May 29, 1955, at 21:30 local time in the Maldonado region. The witness, whose name is partially illegible in the document, observed a single, metallic, top-shaped object moving from north to south. The witness reported that the object exhibited intelligent control, faltering speed, and a rotating motion. Notably, the object changed colors during the observation, transitioning from green to blue and finally to red. The witness explicitly stated that the object made no sound and left no trail, tail, or exhaust. The witness also noted that their spouse observed the same phenomenon and believed it to be an interplanetary craft. The witness described themselves as someone who enjoys observing space and natural phenomena. The official ATIC record card for this incident lists the conclusion as 'Insufficient Data for Evaluation,' while noting the possibility of a meteor or aircraft. The document also includes a separate, unrelated informational note dated May 19, 1955, regarding a sighting in Los Angeles, California, where a fleet of 'silvery flying saucers' was identified by the State Division of Fish and Game as a flock of Pelicanus erythrorhynchos (American white pelicans) floating on wind currents.
