Project 10073 Record — Long Beach, California, 7 April 1966

This document contains the Project 10073 record regarding an unidentified aerial phenomenon sighting reported in Long Beach, California, on 7 April 1966. The primary witness was an 8-year-old youth who observed a single object for approximately 17 seconds from their front yard. The witness described the object as having a color that looked like steel, emitting a sound described as a soft siren, and possessing wings and protrusions. The object was observed moving in front of a field before disappearing over a hill. The witness reported the sighting to the U.S. Air Force. A follow-up letter dated 24 June 1966, signed by Major Hector Quintanilla, Jr., Chief of Project Blue Book, informed the witness that the information provided in their initial letter was insufficient for evaluation and requested the completion of an FTD Form 164. The final conclusion recorded by the Air Force was that there was insufficient data to permit a firm evaluation of the incident.
