Project 10073 Record Card — Ellenton, South Carolina, 10 May 1952

This document is a collection of reports and correspondence regarding unidentified aerial phenomena (UAP) sightings in May 1952. The primary report is a Spot Intelligence Report from the 6th District Office of Special Investigations at Robins Air Force Base, dated 26 May 1952. It details a sighting on 10 May 1952, at the DuPont Savannah River Plant in Ellenton, South Carolina. Four employees reported seeing four disc-shaped objects at 2240 hours, which were yellow or gold in color, approximately 15 inches in diameter, and moving at high speed and altitude without noise. The objects were observed approaching from the south and moving in a northerly direction. Additional sightings were reported by the same group at 2305, 2310, and 2315 hours, with varying trajectories. The report notes that one object flew at a very low altitude, requiring it to pull up to clear tall tanks in the 400 area. The FBI provided this information to the Air Force, and the Atomic Energy Commission was also notified. The 6th District OSI concluded that no further investigation was contemplated by their office. The document also includes a Project 10073 record card summarizing these events, as well as correspondence regarding a separate sighting of a blue-green light over Portland, Oregon, on 10 May 1952, and a report concerning a 12-year-old who photographed an object in San Francisco on 4 May 1952. Furthermore, an Air Intelligence Information Report (IR-23-52) is included, which discusses enemy balloon sightings in Korea during June 1952, noting that some of these were identified as balloons being raised and lowered on cables, possibly for communication purposes. The file contains two 8x10 photographs related to the reported cases.
