Project 10073 Record Card — St. Joseph, Michigan, 15 September 1958

This document is a Project 10073 record card detailing an unidentified aerial phenomenon sighting that occurred in St. Joseph, Michigan, on September 15, 1958. The report, filed by a civilian witness, describes a single, round, gold-colored object observed for approximately 31 minutes. The witness reported that the object appeared to be the size of a baseball held at arm's length and possessed a tail of equal size. The object was observed moving slowly from the northeast toward the south, while local wind conditions were recorded as blowing to the south at 14 knots. The report explicitly notes that no radar contact was made and no photographs were taken. The evaluating agency, ATIC, determined that the information provided was insufficient for a definitive evaluation. Specifically, the report notes that the elevation and azimuth of the object were not reported, which hindered the ability to reach a firm conclusion. The investigators suggested that the object could have been a comet, a planet, or a balloon, though they noted there was no mention of steady flight. The document includes a teletype header and internal routing notes, indicating it was processed through military intelligence channels, including the Air Technical Intelligence Center at Wright-Patterson Air Force Base.
