Project 10073 Record Card and Related Correspondence — Rockville, Indiana, July 1952

This document contains a series of reports regarding an Unidentified Flying Object sighting that occurred on July 22, 1952, near Rockville, Indiana. The primary report, filed by the 782 ACW, describes a triangular, aluminum or silver-colored object, estimated to be the size of a C-47 aircraft. The object was observed by three members of the unit—one officer and two airmen—at approximately 2202Z. The witnesses reported that the object was initially seen to the southwest of the station, traveling toward the northeast. Upon reaching a point approximately one-half mile northwest of the station, the object ceased forward motion and hovered for approximately half a minute. It then moved off to the north and disappeared into the haze. The altitude was estimated to be between 500 and 1000 feet. The observers noted that the object had a single triangular fin or rudder, produced no sound, and left no trail or exhaust. The weather at the time was clear with ground haze and no wind. The report explicitly states that there was no radar contact. A separate, related intelligence report (10-OSI 24-155) discusses a different sighting in Springfield, Massachusetts, on the same date, which was investigated by Special Agent Raworth D. Filson. This second report involves a round, pale orange object observed by a civilian, which was later attributed to fireworks displays at Mountain Park, Holyoke, Massachusetts. The document includes administrative markings indicating it was classified as 'RESTRICTED' and subject to periodic downgrading. The reports were forwarded to the Air Technical Intelligence Center and the Air Materiel Command for review.
