Project 10073 Record Card — Worland, Wyoming, 15 October 1960

This document contains a series of reports and correspondence regarding a UFO sighting that occurred on October 15, 1960, at the Worland Municipal Airport in Worland, Wyoming. Three civilian witnesses, including a school teacher, a station agent for Frontier Airlines, and a flight service specialist, observed an object at approximately 1935 local time. The witnesses described the object as being shaped like an arrow head with the tip pointed toward the ground, appearing the size of a dime. The object's color transitioned from a translucent red at the lower tip to a pale yellow at the upper edges. It was observed for four to six minutes, during which it descended in a nearly vertical path with a slight southward drift, leaving a non-persistent trail or exhaust. The object eventually disappeared instantly at an altitude estimated between 11,000 and 12,000 feet. The investigation, conducted by the Intelligence Division of the 28th Bomb Wing at Ellsworth AFB and evaluated by ATIC, concluded that the sighting was likely caused by a high-flying aircraft reflecting sunlight. The report notes that weather conditions, including clear skies and unlimited visibility, helped rule out the possibility of a balloon. The document also includes supplementary information regarding other sightings in Australia and California, which are marked as 'Information Only' and do not appear to be part of the primary investigation. The primary case file includes detailed weather data, witness descriptions, and administrative correspondence between military units regarding the reporting and classification of the incident.
