Mystery of Lightning XS894 and UFO Radar

Summary

The declassified British document describes an aerial incident that occurred in 1970, where a U.S. pilot, Captain William Schaffner, disappeared during an interception mission. According to radar reports and testimonies, the Lightning XS894 was assigned to investigate an unidentified object that, according to records, reached speeds of up to 20,400 mph. The pilot reported a bright object shaped like a soccer ball and unusual physical effects, such as dizziness and instrument failures. Despite search efforts, neither the pilot nor his body were found, and the aircraft's cockpit was empty after being recovered from the seabed. The RAF attributed the accident to operational errors and technical failures, but the pilot's account and radar data raised speculation about an encounter with an unidentified object.

The official RAF account states that the pilot, a U.S. Air Force exchange officer, was not fully qualified for the night mission and that the accident was caused by an approach error. However, radar reports and the pilot's description suggest an unusual experience. The unidentified object was detected by multiple radar stations, including Fylingdales, and was moving at speeds impossible for any known aircraft. The pilot described a luminous conical object and physical effects that impaired his reaction. Although the RAF concluded that the pilot attempted an unsuccessful ejection and drowned, the absence of his body and the recovery of the aircraft with the ejection seat intact raised unanswered
