Incident #110 Sighting Report — Baltimore, Maryland, 23 March 1948

This document details Incident #110, a report of unidentified aerial sounds occurring in the Hamilton neighborhood of Baltimore, Maryland, on March 23, 1948. The primary witness, whose identity was kept confidential, contacted the Baltimore FBI office to report hearing peculiar noises in the sky between 0300 and 0500 hours. The witness, described as the wife of a former U.S. military member and active in American Legion activities, stated that the sounds resembled the motor drone of a foreign-type aircraft rather than standard American planes. She further noted that she had discussed the matter with a neighbor, also an unidentified woman, who confirmed hearing similar noises and whose husband, an ex-G.I., had also characterized the sounds as resembling those of foreign aircraft. The report was forwarded by Headquarters Strategic Air Command to the Director of Intelligence of the United States Air Force. The official evaluation, as recorded in the Project Grudge report index, concluded that there was nothing astronomical about the incident and that the limited nature of the information provided precluded any further investigation or explanation. No action was contemplated by the Strategic Air Command.
