Background

On August 6, 1947, in Tacoma, Washington, 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

The report details an investigation into Fred Crisman, a former fighter pilot and Air Reserve Captain. Crisman had reportedly discussed unidentified flying objects with Capt. Smith and Mr. Arnold. Investigators verified Crisman’s military service and background, noting prior legal issues.

The number of witnesses is not specified in the released document.

Type of case

The case is a pilot or aircrew sighting, observed from the cockpit during flight.

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.
