Summary

On July 23, 1955, in Seattle, Washington, both civilian and military observers reported one round object. The Air Force recorded the report under Project 10073, its official record for unidentified flying object reports.

The object looked about the same size as a star and appeared to be bobbing. The sighting lasted about 30 minutes.

The Air Force noted the witness was in an area of heavy balloon activity. Officials concluded the description and the duration all pointed to a balloon.
