Project 10073 Record — Cloverdale, California, 23 April 1966

This document contains the official Air Force record and correspondence regarding a UFO sighting reported by a civilian in Cloverdale, California, on April 23, 1966. The witness reported observing approximately 15 objects in a V-formation, described as white glowing masses and white mist, traveling north at a high speed at an altitude of approximately two miles. The witness noted that there was no sound associated with the objects. The report includes a completed U.S. Air Force Technical Information questionnaire, in which the witness provided details about the sighting, including the duration of 20 minutes and the weather conditions, which were described as dry and clear. The witness also provided a sketch of the objects' movement and formation. The correspondence shows that the witness initially reported the sighting to the Public Information Officer at Hamilton Air Force Base, California, on May 3, 1966. The report was subsequently forwarded to the Foreign Technology Division at Wright-Patterson Air Force Base, Ohio, for evaluation by Project Blue Book. Major Hector Quintanilla, Jr., Chief of Project Blue Book, sent a letter to the witness on May 11, 1966, requesting further information. The final conclusion recorded on the Project 10073 record form is that the objects were 'Other (birds),' with the analysis suggesting that the bright moonlight enabled the observer to see the birds in formation.
