Project 10073 Record Card and Air Intelligence Information Report — El Paso, Texas, September 1952

This document is an Air Intelligence Information Report (IR-147-52) detailing a series of sightings of unidentified flying objects reported by a consulting engineer in El Paso, Texas, on the night of September 14-15, 1952. The witness, accompanied by three others, observed six groups of luminous, spherical, or disc-shaped objects traveling in formations that shifted from arcs to an 'inverted Y' pattern. The objects were reported to be moving at approximately 4,000 mph at an altitude of 10-12 miles. The witness described the movement as erratic, including hovering and high-speed rectilinear flight, with no visible means of propulsion, exhaust, or sound. The observations were made near the Santa Fe Bridge, which crosses the Rio Grande River between El Paso, Texas, and Juarez, Mexico. The report includes detailed schematic drawings and personal observations provided by the witness, who claimed to have studied astronomy and navigation. The witness noted that the objects were visible through an icy haze at 10,000-15,000 feet. Military intelligence at the 97th Bombardment Wing, Biggs Air Force Base, conducted a preliminary check and found no known meteorological conditions or air traffic that could account for the sightings. The report concludes that the reliability of the source is undetermined and that no physical evidence was found. The document includes a teletype message (IDA 1774) and various worksheets and charts documenting the observer's claims. The report was forwarded to the Eighth Air Force headquarters without further evaluation.
