Project 10073 Record Card — Unconventional Flying Object Report, 6 September 1952

This document is an Air Intelligence Information Report regarding an unconventional flying object sighting reported on 6 September 1952. The report, filed by the 647th AC&W Squadron in Manassas, Virginia, details an observation made at 0145Z by personnel at the Baltimore Filter Center, including 2nd Lt. Baxter T. Duncan, T/Sgt. Ira Wilson, and Mr. Fred Simon of TV Station WAAM. The witnesses described a bright white light that flashed for one to two seconds at sixty-second intervals. The object was sighted approximately five to fifteen miles east of the Baltimore Filter Center, at coordinates 39 degrees 15 minutes North and 76 degrees 35 minutes West. Following the report, two F-94 fighter aircraft from the 148th Fighter-Interceptor Squadron, which were on combat air patrol, were vectored to the area to investigate. The pilots reported seeing a flashing white light resembling an explosion in the southeast corner of the Aberdeen Proving Grounds at 0224Z. Subsequent investigation by the Baltimore Filter Center personnel confirmed that test firing activities were being conducted at the Aberdeen Proving Grounds at the time of the sighting. The report concludes that the observed phenomenon was likely associated with these test firings. The document includes standard administrative details, such as weather conditions at the time of the sighting—noting clear skies and five-mile visibility—and the reliability of the witnesses, which was noted as unknown. The report was processed under Project 10073 and distributed to various intelligence commands, including the Air Technical Intelligence Center.
