A first saucer wave case from Baltimore, Maryland. On March 29, 1952, while driving near Baltimore, STEWART and his companion observed a strange, flat disk-shaped aircraft with a dome.
Background
On May 10, 1952, in Baltimore, Maryland, U.S. government investigators recorded an unidentified-object incident later released to the public on May 8, 2026 as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The incident is one of the first wave of “flying saucer” reports that swept the United States after the Kenneth Arnold sighting of June 1947 and the Roswell incident of July 1947. The case was filed with the Federal Bureau of Investigation, whose Knoxville, Albuquerque, Los Angeles, and other field offices routed UFO reports to headquarters under the Bureau’s standing protocols for the protection of vital installations.

The object approached their car from the northeast and hovered above them, emitting bright lights. STEWART considered firing a Thompson submachine gun at the craft but was dissuaded by his companion.
The number of witnesses is not specified in the released document.

Status
All records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office (AARO) by default. The federal government has not concluded that the events were anomalous, has not concluded that they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of this period include experimental aircraft, weather balloons (especially the Project Mogul series in the late 1940s), atmospheric optical phenomena such as sundogs and lenticular clouds, and astronomical objects including Venus, the Moon, and meteors near the horizon.
