Declassified documents related to the 1986 Japan Airlines Flight 1628 UFO encounter over Alaska have resurfaced, sparking renewed interest in the event [1, 2]. On November 17, 1986, Captain Terauchi's flight, en route from Paris to Narita, reported observing unusual lights and a massive 'mothership' while flying over Alaskan airspace [2, 6, 12, 13, 15].
The pilot radioed Anchorage air traffic control (ATC), describing a 'large black chunk' with pulsating lights approximately five miles ahead [6, 9, 13, 15]. Anchorage ATC confirmed radar contact near the airplane, while NORAD verified that no military aircraft were in the vicinity [6, 13].
Recently, attention has been drawn to records of the incident, including radio transcripts, which have been quietly entered into the U.S. government's National Archives [1, 8]. These records detail the moment the giant mothership appeared above Flight 1628, adding weight to Terauchi's account [1, 6, 13]. The event remains one of the most compelling UFO encounters in aviation history [2, 6, 12].
