Seattle kept a local saucer file

This is the FBI Seattle file 100-18945, collecting Washington State flying saucer and UFO reports from 1952 to 1960, with newspaper clippings, citizen complaint forms, and Air Force correspondence. Several sightings are tied to ordinary explanations such as a weather balloon, an aircraft flare, and possible normal aircraft. That mix of solved cases sitting next to unsolved ones is exactly what an honest UFO file should look like.
