Unidentified Flying Object Sighted by SA JAMES B. STEPHENS, Jr., 297 54 19, USN, San Nicolas Island, California, 22 April 1954

This document is a collection of official military reports regarding an unidentified flying object sighting on San Nicolas Island, California, on April 22, 1954. The primary witness, SA James B. Stephens, Jr., reported observing a gray, cigar-shaped object, approximately four to six feet in diameter and length, while traveling in a Navy carryall vehicle. Stephens stated that the object was moving at an appreciable speed just above the ground and appeared to be on a trajectory that would cross the road in front of his vehicle. He further claimed that the object struck the ground in a semi-flat attitude, resulting in a cloud of dust or smoke at the impact site. Stephens immediately alerted his companion, Bernard G. Klein, Jr., who was driving the vehicle; however, Klein stated that he did not see the object. Despite this, the two men conducted a twenty-minute search of the area but found nothing. The incident was subsequently reported to the Officer-in-Charge of San Nicolas Island, Lt. W. S. Cates. Following the report, an intensive search of the area was conducted by a party including Cates, Stephens, Klein, and Kenneth Duckhorn, which also yielded negative results. Further investigative measures included a check with underground radar, which confirmed that no aircraft were in the vicinity of the island at the time of the sighting. Additionally, personnel from the RADSAFE School at Naval Air Station, Point Mugu, utilized special equipment to survey the area for potential radioactive residue, but these efforts also resulted in negative findings. The official conclusion reached by the Air Technical Intelligence Center was that there was insufficient data for a formal evaluation of the incident. The documentation includes the original spot intelligence report, the formal transmittal from the 18th OSI District to the Air Technical Intelligence Center, and the individual sworn statements of the involved personnel.
