Washington UFO Sighting (July 26, 1947) — FBI Files
A first saucer wave case from Washington, District of Columbia. On July 26th, radar detected unidentified objects over Washington, prompting the dispatch of two jet interceptors.
Background
On July 26, 1947, in Washington, District of Columbia, 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.
What the document records
On July 26th, radar detected unidentified objects over Washington, prompting the dispatch of two jet interceptors. One pilot sighted four lights that vanished as he approached, and later a single white light that also disappeared. The Air Force stated they had no evidence to confirm or deny the objects were flying saucers.
The number of witnesses is not specified in the released document.
Verbatim from the file
“We have no evidence they were flying saucers. Conversely, we have no evidence they were not flying saucers. We don’t know what they were.”
Type of case
The case is principally a radar track, with the unidentified object being detected on military or civilian radar equipment.
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.
