Project Blue Book Case File
Lumberton, OhioMay 1956
Summary
On the evening of May 23, 1956, a resident of Lumberton, Ohio saw a bright blue-white light moving across the sky. At 9:12 p.m. EST, the observer was walking in the driveway of his home when he noticed the light, which seemed too bright to be ordinary aircraft lights. The light traveled at a medium-fast speed with no sound. Over the course of about 30 minutes, the object appeared and disappeared multiple times, moving from left to right and then right to left behind nearby trees. The observer noted that the light sometimes resembled a searchlight, but at other times appeared as a steady blue-white glow. Estimating the object's altitude at approximately 5,000 feet, the observer calculated its speed at roughly 75 miles per hour.
After the sighting generated multiple calls to Wright-Patterson Air Force Base from alarmed residents in the Xenia area, the Air Force determined the answer quickly. Newspaper accounts from late May 1956 reveal that the light was caused by an RF-84F jet aircraft conducting night aerial photography missions for the Wright Air Development Center. The plane carried high-intensity mercury arc lamps mounted in wing pods, which were used for experimental nighttime reconnaissance photography. The Air Force stated that similar flights would continue through mid-June 1956 in the southern Ohio, Kentucky, and western Pennsylvania region during clear weather.
The Air Force's conclusion recorded on the case file is that the object was probably an aircraft conducting test flights. The full case file is reproduced below as held by the National Archives, consisting of 13 pages.
