Project 10073 Record Card — Sighting near Wenatchee, Washington, 20 October 1958

This document is a Project 10073 record card and associated teletype report detailing a sighting of an unidentified aerial phenomenon near Wenatchee, Washington, on 20 October 1958. The witness, a 40-year-old civil engineer, observed a large, white light, estimated to be ten times the size of Venus at its brightest, moving from south to north for approximately seven minutes. The observation was made using binoculars, which revealed no additional features or silhouette. The weather conditions were reported as clear with perfect visibility. The investigating officer from the 62nd Troop Carrier Wing noted that while the witness possessed above-average intelligence and technical knowledge, his interest in science fiction likely influenced his interpretation of the event. The official conclusion reached by the Air Technical Intelligence Center was that the object was likely the star Arcturus. The report acknowledges that while the object could have been a high-altitude aircraft such as an F-104, the presence of such aircraft could not be confirmed, leading to the submission of the report despite the likely astronomical explanation.
