Project 10073 Record Card — Renton, Washington, March 1957

This document consists of a Project 10073 record card and associated teletype communications regarding a UFO sighting reported on March 27, 1957, in Renton, Washington. The primary witness, identified as RM Hadway, an ex-Air Force pilot associated with the Ground Observer Corps (GOC), reported observing two hovering lights drifting to the east. The sighting lasted for at least 30 minutes. The report notes that the objects were also observed by a neighbor. The Washington State Patrol was notified and conducted an investigation. The teletype report indicates that the objects were seen drifting east, gaining altitude, and decreasing in intensity. The report further notes that the Washington State Patrol investigated the area and reported no flashing lights, suggesting that the sighting may have been caused by an airway beacon light located three miles east of Is Aguah at Squah Mountain. A subsequent investigation assigned to flight 1-A 4602d of the Air Intelligence Service Squadron (AISS) concluded that the sighting was caused by a balloon.
