Project 10073 Record Cards and Related Correspondence — Seattle, Washington, July 1956

This document consists of a series of Project 10073 Record Cards and associated military communications regarding Unidentified Aerial Phenomena (UAP) sightings in the Seattle, Washington area during July 1956. The reports detail multiple observations, including a white, star-like object that left vapor trails and circled, and a cigar-shaped object with a steady red light. Military personnel, specifically LT COND. C.W. BRAM DENDERG of the 13th Naval District, recorded information from civilian witnesses. The reports were forwarded to the Air Technical Intelligence Center at Wright-Patterson Air Force Base in accordance with ADCR 200-7. The official conclusions for these sightings generally attribute the phenomena to conventional aircraft or balloons. One specific report from July 22, 1956, describes an object resembling a balloon or parachute observed through binoculars at an estimated altitude of 15,000 feet. The investigator noted that because the object remained aloft for at least 20 minutes and balloon sites were known to exist in the Seattle area, it was likely a balloon. The documentation provides a structured look at the military's process for collecting and evaluating civilian reports of aerial phenomena during this period, emphasizing the role of local naval and air force units in gathering data for intelligence assessment.
