Seattle-Tacoma Airport UFO Sighting (August 22, 1949) — USAF Files
Two air traffic controllers observed an unidentified object resembling an F84 aircraft thirty miles west-northwest of Seattle-Tacoma Airport in 1949.
Background
On August 22, 1949, at the Seattle-Tacoma Airport in Washington, U.S. government investigators recorded an unidentified-object incident. The details of this encounter remained classified for decades until they were released to the public on May 8, 2026, as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). This specific sighting occurred during a period of heightened public and military interest in aerial phenomena. The incident is categorized as part of the first wave of “flying saucer” reports that swept the United States following the Kenneth Arnold sighting in June 1947 and the Roswell incident in July 1947. During this era, the emergence of unidentified aerial phenomena prompted significant scrutiny from the Department of Defense and various intelligence agencies, as the early Cold War necessitated a heightened state of vigilance regarding any unidentified movement in national airspace. The case is documented within official U.S. Department of Defense records.
The Incident
The documentation regarding the August 22 event focuses on a specific observation made by personnel responsible for monitoring regional airspace. Two air traffic controllers observed an object approximately thirty miles west-northwest of Seattle-Tacoma Airport. The observers noted that the object’s shape and speed were similar to an F84 aircraft, a common jet fighter of the period. However, the controllers noted a distinct lack of typical flight behavior, as the object did not maneuver during the period of observation. Despite the proximity to a major transit hub, no photographs or sketches of the object were available to investigators at the time of the report. While the released document provides specific details regarding the nature of the sighting, the total number of witnesses is not specified in the official record.
Analysis and Contextual Classification
The case is classified as a visual sighting reported by ground or air observers. In the context of mid-century aerial investigations, such reports were often analyzed against the backdrop of rapid advancements in aeronautics and atmospheric science. During the late 1940s, the presence of unidentified objects in the sky was frequently scrutinized through the lens of burgeoning aerospace technology and clandestine military operations.
All records released under the PURSUE program are designated as unresolved by the All-domain Anomaly Resolution Office (AARO) by default. The federal government has not concluded that the events were anomalous, nor has it concluded that they were conventional, and it has not ruled out either possibility. When evaluating sightings from this era, investigators often consider several conventional candidates. These include experimental aircraft developed during the early jet age, weather balloons—specifically those associated with the Project Mogul series in the late 1940s—and various atmospheric optical phenomena such as sundogs or lenticular clouds. Additionally, astronomical objects such as Venus, the Moon, or meteors appearing near the horizon are frequently evaluated as potential explanations for unidentified aerial sightings.
