Project 10073 Record Card and Associated Correspondence — Fort Yukon, Alaska, December 1960

This document contains a series of military communications and a Project 10073 record card regarding a UFO sighting reported on December 5, 1960, near Fort Yukon, Alaska. A civilian witness, identified as an RCA employee, reported observing a round, white object with green edges, approximately the size of a quarter or baseball. The object was sighted at a 30-degree elevation and 185-degree azimuth. According to the report, the object moved in a straight line toward the horizon at a 5-degree angle from straight down, before disappearing almost instantaneously to the southwest. The entire event lasted between two and three seconds. The weather conditions at the time were clear and cold, with a temperature of minus 25 degrees and a dew point of minus 37 degrees. The report was processed by the 709th Aircraft Control and Warning Squadron at Fort Yukon Air Force Station and forwarded to the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base. Initial internal comments on the record card noted that while there was a satellite (Zeta II) reentering the atmosphere on that date, the characteristics of the observed object made it improbable that it was the satellite. The investigating personnel concluded that the description and duration of the sighting were more characteristic of a meteor. The documentation includes the original record card, a series of teletype messages between military units requesting and providing specific details on the sighting, and a formal inquiry from ATIC requesting further information on the witness and the exact coordinates of the observation.
