Project 10073 Record — Sacramento, California, 28 April 1966

This document contains the official record for Project 10073, concerning a UFO sighting reported by a civilian aircraft worker near McClellan AFB, California, on 28 April 1966. The witness reported observing two bright white, football-shaped objects at approximately 2300 hours while walking home in the vicinity of Madison Avenue and Sunrise Avenue in Carmichael. The witness described the objects as moving independently, sometimes stopping, and traveling at roughly 50 mph. At one point, one of the objects reportedly stopped and emitted a bright light, described as resembling landing lights, for several seconds. The witness noted the objects made a loud sound, similar to a jet, at one point during the 45-minute observation. The report includes a formal statement from the witness, a hand-drawn map of the sighting area, and a letter from Major Hector Quintanilla, Jr., Chief of Project Blue Book, dated 23 June 1966. The Air Force concluded that there was insufficient data for a formal evaluation, primarily because the witness failed to return the required FTD Form 164 within the 30-day window provided for follow-up.
