Editorial summary

This FBI file documents an investigation of reported sightings of unidentified flying objects in Washington State between July 1952 and August 1960, including memoranda and correspondence between the FBI and the U.S. Air Force. The records reference newspaper accounts and witness reports, including a July 1952 disk-shaped object reported near Pasco and a 1953 account from a Seattle witness who described a very large, bright, silvery object high above and west of a naval air station that moved off to the north after about two minutes. Another letter describes a shimmering high-altitude object observed through a telescope that darted off to the west.
