Sighting of a flying saucer by certain Lockheed Aircraft Corporation personnel on 16 December 1953

This document is a collection of reports compiled by Clarence L. Johnson, Chief Engineer at Lockheed Aircraft Corporation, regarding an Unidentified Aerial Phenomenon (UAP) sighting on December 16, 1953. The primary correspondence, dated January 20, 1954, is addressed to the Commander of the Air Technical Intelligence Center at Wright-Patterson Air Force Base. It encloses individual reports from five Lockheed personnel: C. L. Johnson, R. L. Thoren, R. E. Wimmer, P. A. Colman, and J. F. Ware. The witnesses, who were experienced pilots and engineers, observed the object from two different perspectives: one group was aboard a Navy Super Constellation WV-2 aircraft flying off the coast of California, while Clarence L. Johnson observed it from his ranch near Agoura. The witnesses described the object as a large, black, elliptical or wing-shaped craft that appeared stationary for several minutes before accelerating rapidly to the west. The reports highlight the witnesses' professional skepticism and their inability to identify the object as a conventional aircraft or cloud formation. The document includes sketches of the object's shape and ratio, as well as personal accounts detailing the specific circumstances of the sighting. The submission was intended for the Air Force's scientific evaluation, with the explicit note that the information had not been released to the press.
