Unconventional Aircraft Sighting Report — Ogden Dunes, Indiana, 16 July 1952

This document is an Air Intelligence Information Report regarding an unconventional aircraft sighting reported to the Headquarters Fifth Army in Chicago, Illinois. On 17 July 1952, an individual from Ogden Dunes, Indiana, contacted the military to report an observation made the previous evening. At approximately 2200 hours on 16 July 1952, the witness observed a large, orange-colored light moving at high speed from west to east across Lake Michigan. The object was estimated to be at an altitude of approximately 2,000 feet and appeared to be the size of a full moon. The witness noted that the object traveled in a straight line and did not exhibit the erratic movement associated with meteors before disappearing suddenly. Approximately one minute later, a second object with identical characteristics was observed in the same vicinity. The witness was located at the lakefront in East Chicago, Indiana, at the time of the sighting. The report was forwarded by the Fifth Army to the A-2 office at Selfridge Air Force Base, Michigan, under the project designation Project 10073. The official response from the Fifth Army headquarters stated that no further action was contemplated regarding the matter. The document includes administrative markings indicating it was later downgraded and declassified under DOD Directive 5200.9.
