On the afternoon of July 4, 1947, Frank Ryman, an off-duty U.S. Coast Guard Yeoman, snaps the first photograph of an alleged "flying saucer" from the yard of his home in Lake City, north of Seattle.
The photo showed a small bright disc against a dark sky and was published by the Seattle Post-Intelligencer the following morning.
The photo made front page news amid a rash of UFO sightings triggered by press reports of Kenneth Arnold's encounter with nine flying "saucer-like" objects over the Cascades on June 24, 1947. Analysts later concluded that Ryman had photographed a weather balloon.
