Project 10073 Record Card and Transmittal of Information — Carlisle, Pennsylvania, August 1961

This document consists of a Project 10073 record card and associated correspondence regarding an unidentified aerial phenomenon reported on August 8, 1961, near Carlisle, Pennsylvania. A group of individuals, while meeting at a company guest house on a mountain top, observed a bright light overhead at 2158 hours. The witnesses described the object as being brighter than any star and moving in an East by North direction. They noted that the object moved erratically, occasionally jumping ahead, though they acknowledged these movements could potentially be attributed to atmospheric conditions or eye concentration. The object remained visible for 5 to 10 minutes before disappearing behind tree tops. The witness, who initially reported the incident to the Federal Bureau of Investigation, explicitly stated that the object was not an airplane. The FBI subsequently referred the letter to the Department of the Air Force, noting that the matter fell under Air Force jurisdiction. The Air Force's internal evaluation, recorded on the Project 10073 card, suggested the object might have been the Echo I satellite, but concluded there was insufficient data to confirm this hypothesis. The record card further notes that a request for additional information was sent to the witness, but no response was received.
