AI Summary
The document discusses the analysis of the Japan Air Lines (JAL) Flight 1628 UFO incident that occurred on November 17, 1986. The pilot, Captain Kenju Terauchi, reported seeing a UFO while flying over Alaska, which was later attributed to misidentification of celestial bodies, particularly the planet Jupiter. The analysis includes insights from FAA data and interviews with the flight crew.
Key Findings
- The JAL pilot is a 'UFO repeater' with multiple prior sightings. - Initial radar blips were misidentified and attributed to radar anomalies. - Other aircraft in the vicinity did not observe the reported UFO. - The bright lights reported by the pilot could be explained by reflections from ice crystals and moonlight. - The FAA provided extensive data to the public, contradicting claims of a cover-up.

Klass T H E UFO MOVEMENT, suffering from an extended drought of excit- ing new UFO incidents to attract media and public interest, got a sorely needed shot in the arm in early January, when it was disclosed that the pilot of a Japan Air Lines 747 cargo airliner had reported an encounter with a giant UFO over Alaska on November 17, while flying to Anchorage from France. The incident had occurred in twilight conditions, starting about 6: 15 P.M. local time, with the sun abo ut 11 degrees below the horizon. According to initial press reports, the incident seemed a classic. The principal witness was an experienced captain, Kenju Terauchi, whose reported visual observations seemingly were confirmed by a USAF/ Federal Aviation Admini- stration radar. Additionally, th e UFO seemingly paced the JAL 747 for more than 40 minutes, offering an extended period for observation by two other crew members of the cargo aircraft loaded with French wine destined for Japan. Important new insights into the inci- dent have since emerged as a result of t he FAA's wise decision to offer a com- plete data package to the public at modest cost. The available data includes a ver- bat im transcript of the JAL pilot's tape- re cord cd radio communications with 322 FAA controllers during the incident, tape recordings and transcripts of FAA inter- views with thc·three JAL crew members in early January, about six weeks after the incident occurred, and a copy of the revealing report that Captain Terauchi submitted to the FAA, also in early January. In releasing all available data on the incident, the FAA's Alaskan Region pub- lic affairs officer, Paul Steucke, noted that his agency "does not have the re- sources or the Congressional mandate to investigate sightings of unidentified flying objects. We have not tried to determine what the crew of Japan Air Lines flight 111628 saw based on scientific analysis of the stars, planets, magnetic fields, angle of view, etc." During the initial phase of the November 17 UFO iricident, a Jong-range USAF/FAA radar sporadically seemed to show a singl e blip in the vicinity of the 747's radar blip-at a time when the pilot was reporting seeing several UFOs. Fortunately, the FAA records radar data (for subsequent analysis in event of a mid-air collision or a near-miss), and it was sent to the FAA's technical center near Atlantic City for analysis by rada r specialists, to determine if the Jong-range USAF/FAA radar had indeed detected THE SKEPTICAL INQUIRER, Vol. 11 an unidentified object in the vicinity of the JAL 747. This analy sis showed that the sporadic second blip was due to a phenomenon known as "uncorrelated primary and bea- con target," which can occur if the radar energy bouncing off an aircraft does not arrive at precisely the same instant as the signal transmitted back by the aircraft's radar transponder. According to FAA specialist Dennis R. Simantcl, who ana- . Iyzed the data, "these uncorrelated pri- mary returns arc not uncommon due to the critical timing associated with the delay adjustments in the aircraft tran- sponder . .. and the target correlation circuitry within the radar equipment." The FAA data package reveals Terauchi to be a "UFO repeater," with two other UFO sightings prior to November. 17, and two more this past January, which normally raises a "caution flag" for exporienced UFO investigators. The JAL pilot is convinced that UFOs are extraterrestrial and when describing the Jight(s) Terauchi often used the term spaceship or mothership. During his January 2 interview with FAA officials, Terauchi said that he be- lieved the "mothership" intentionally positioned itself in the "darkest [easterly] side" of the sky because "I think they did not want to be seen.'·' This enabled the UFO to sec the 74 7 "in front of the sunset and visible for any movement we make." In his report to the FAA, he expressed the hope that "we humans will meet them in the near future." Terauchi, who was based in Anchor- age at the time but has since been trans- ferred back to Japan, noted in his report that his flights over Alaska "generally (are] in the daytime and it is confusing to identify the kind of lights" in darkness. As an example, he described seeing lights from an Alaskan pipeline pumping sta- tion reflecting off snow-covered moun- tains, which initially puzzled him. (On …
