Project 10073 Record Card — Brookfield, Ohio, 15 August 1958

This document is a Project 10073 record card and accompanying teletype report regarding an unidentified aerial phenomenon sighting on 15 August 1958 near Brookfield, Ohio. A single witness observed a small, white, oval-shaped object for approximately 2.5 minutes. The object was described as flashing alternately while traveling in a southeasterly direction before fading from sight. The report, originating from the 662nd Aircraft Control and Warning Squadron (ACWRON) at Brookfield Air Force Station, indicates that the sighting was not captured on radar and no photographs were taken. The official conclusion reached by the evaluating authorities was that the object was a probable aircraft, citing the flashing lights and speed characteristics as consistent with standard aviation. Intelligence Officer 1st Lt. Howard H. Kelly provided additional commentary, noting that the observer could not provide specific elevation or azimuth data. He further remarked that while the flashing lights suggested aircraft running lights, the available information was insufficient to reach a definitive conclusion. Interestingly, the report also contains a note suggesting the object was believed to be part of a satellite or rocket circling. The document includes detailed meteorological data regarding winds aloft at various altitudes, likely used to assess potential atmospheric phenomena or balloon drift, though the final assessment leaned toward conventional aircraft.
