Project 10073 Record Card and Augmented UFO Report — Earnest Harmon AFB, October 1955

This document contains a series of military communications and a Project 10073 record card detailing an unidentified aerial phenomenon (UAP) sighting at Earnest Harmon Air Force Base in Newfoundland on October 12, 1955. The primary witnesses, including an M/Sgt and an A/1C from the 6605th Air Base Wing, reported observing a shapeless, bluish-white light at approximately 0315Z. The witnesses described the object as being roughly the size of a pea at arm's length, moving in a manner that included hovering, rocking, swaying, and making radical changes in course before performing a rapid vertical climb and disappearing. The witnesses noted that the object's speed appeared to exceed that of any jet aircraft they had previously observed. The report includes detailed meteorological data and logs from the base, noting that a weather balloon had been released at 2230Z on October 11, 1955, and that its radio transmitter had failed. Intelligence officers investigating the incident concluded that the sighting was likely caused by this weather balloon, which was illuminated by 1 1/2 volt batteries and carried by wind currents consistent with the path described by the observers. Despite the witnesses' insistence on the object's unusual flight characteristics, the official assessment attributed the event to the balloon, noting that the object's appearance and behavior were consistent with such an explanation under the observed weather conditions.
