Sighting of Unidentified Aerial Objects on 26 February 1953, at Kingsville, Maryland, and 5 March 1953, at Baltimore, Maryland

This document is a special inquiry report from the 4th District Office of Special Investigations, dated 9 April 1953, concerning two sightings of unidentified aerial objects in Maryland. The primary report details an incident on 26 February 1953, involving a Captain from the Army Environmental Health Laboratory. While driving west on U.S. Route 1 near Kingsville, the witness observed a luminous, elliptical object in the northeast sky at approximately 0739 hours. The witness, who possessed a background in physics, described the object as self-illuminated with a brightness and color temperature comparable to the sun. The object appeared stationary for a period, then its brightness diminished, and it assumed a mushroom-like shape before moving in an easterly direction. The witness lost sight of the object as it moved behind a hill. The report notes that the witness had 20/20 vision and experience with light phenomena, yet the official conclusion reached by the Air Force was that the object was likely an aircraft at a distance reflecting sunlight, noting that the witness was in a moving vehicle, which may have hindered proper observation. Follow-up investigations conducted by an agent of the Office of Special Investigations on 26 February 1953 included a site visit to the location of the sighting and a compass reading. Checks with the 208th AAA Battery and the Churchville Ordnance Corps tank proving ground were performed to rule out the use of pyrotechnics or other military activity in the area, both of which returned negative results. The document serves as a formal record of the investigation into the sighting, emphasizing the military's attempt to identify the phenomenon through standard intelligence assessment procedures.
