Project 10073 Record Card - Seattle, Washington - 21 July 1955

This document consists of a Project 10073 Record Card and an associated teletype report regarding an Unidentified Aerial Phenomena (UFOB) sighting that occurred on July 21, 1955, in Seattle, Washington. The report was filed by the 635th Aircraft Control and Warning (ACW) squadron at McChord Air Force Base. The witness, identified as SSGT A.V. Whitney of the Seattle Ground Observer Corps (GOC), reported observing a single, round, black object. The witness estimated the size of the object to be equivalent to a quarter held at arm's length. According to the report, the object was observed overhead and appeared to move straight up before disappearing. The duration of the observation was approximately two minutes. The report explicitly notes that no photographs were taken and no radar contact was made. The official conclusion reached by the evaluating authorities was that there was insufficient data to provide a definitive explanation for the sighting. Consequently, it was determined that an AF Form 112 would not be submitted for this incident. The documentation follows standard military reporting procedures for the era, specifically citing AFR 200-2, paragraph 7, as the regulatory basis for the submission.
