Project 10073 Record and Incoming Message Reports — McChord AFB, March 1966

This document is a collection of Project 10073 records and Air Force incoming messages detailing multiple UFO sightings reported in the vicinity of McChord AFB, Washington, between March 26 and March 27, 1966. The reports involve several witnesses, including military personnel and civilians, who observed one to three objects moving in a westward direction. Descriptions of the objects varied, with witnesses characterizing them as transparent kites, bi-planes, or rectangular boxcar-like structures with banana-shaped appendages. Despite the varied descriptions, the objects were consistently reported as having no sound, no exhaust, and moving slowly without erratic maneuvers. The sightings typically lasted between 20 and 30 minutes and occurred during dusk. The Air Force investigation, led by 1st Lt. James L. Cotton of the 318th Fighter Interceptor Squadron, concluded that the observations were consistent with weather balloons, noting that launches occurred at 6:00 PM and that the flight characteristics and appearance matched such phenomena. No intercept action was taken, and no physical evidence was recovered. The reports emphasize clear weather conditions and good visibility during the incidents.
