In November 1986 the crew of Japan Airlines Flight 1628 reported three unidentified objects pacing their Boeing 747 freighter for more than thirty minutes while flying over Alaska.
The sighting occurred during a routine cargo flight from Paris to Tokyo via Anchorage. Captain Kenju Terauchi, First Officer Takanori Tamefuji and Flight Engineer Yoshio Tsukuba each described objects that displayed unusual flight characteristics. Air traffic controllers tracked one of the objects on radar, adding an independent data point to the visual reports.
Commercial airline crews operate under strict protocols that require immediate notification of air traffic control when unknown traffic is observed. The JAL 1628 case followed those procedures exactly. The incident therefore entered official records rather than remaining an anecdotal claim.
Background to the Flight
Japan Airlines operated regular transpacific cargo services in the mid-1980s using converted Boeing 747s. Flight 1628 departed Paris on 16 November 1986 and refuelled in Anchorage before continuing toward Tokyo. The aircraft carried a load of French wine and carried no passengers, allowing the three-man crew an unobstructed view from the elevated cockpit.
Weather conditions that evening were clear with excellent visibility. The flight path crossed remote areas of northern Alaska where commercial traffic is light. Such conditions reduce the likelihood of misidentification with other aircraft or ground lights.
The Encounter Sequence
At approximately 17:10 local time the crew noticed two lights several miles ahead and slightly below their altitude. The objects appeared to maintain formation with the 747 despite changes in the aircraft’s heading and speed. Captain Terauchi later described the lights as rectangular with a greenish tint and a pulsating centre.
After several minutes the two objects moved to positions on either side of the aircraft. A third, much larger object then appeared directly in front of the 747. Terauchi estimated its size as comparable to two aircraft carriers. The crew reported that the large object emitted a faint amber glow and appeared to have a structured shape with rows of lights along its length.
The crew contacted Anchorage Air Traffic Control and requested permission to alter course. Controllers observed an unidentified return on radar that coincided with the pilots’ reported position of the large object. The radar contact persisted for several minutes before fading.
Witness Accounts and Crew Reactions
Each crew member provided separate statements after landing. Terauchi, a veteran pilot with more than ten thousand hours, emphasised that the objects performed manoeuvres impossible for conventional aircraft of the period. Tamefuji noted that the objects changed brightness in a coordinated pattern. Tsukuba recorded instrument readings that showed no corresponding mechanical interference.
The crew remained on duty for the remainder of the flight and filed a detailed report upon arrival in Tokyo. Japan Airlines management forwarded the statements to the Federal Aviation Administration without alteration. The consistency across three independent observers strengthened the credibility of the account.
Official and Independent Investigations
The FAA reviewed radar tapes from Anchorage and the nearby military installation at Elmendorf. Analysts confirmed an unidentified return that matched the timing and location described by the pilots. No military exercises or known aircraft were operating in the area at the time.
The Japan Civil Aviation Bureau conducted its own review and found no procedural errors by the crew. The case was later examined by the Mutual UFO Network and by researchers affiliated with the Center for UFO Studies. Both organisations obtained the original FAA radar data through freedom of information requests.
Competing Explanations
Sceptical analyses have proposed that the crew mistook Jupiter and Mars for the initial lights. However, the reported movement of the objects against the stellar background and the radar confirmation contradict this interpretation. Temperature inversions capable of producing radar anomalies were not present that evening according to meteorological records.
Another suggestion attributes the sighting to ice crystals reflecting ground lights. The clear atmospheric conditions and the structured appearance described by the crew make this explanation unlikely. No similar optical effects were reported by other aircraft in the region on the same night.
Physical and Documentary Evidence
The primary evidence consists of the crew statements, the FAA radar recording and the air traffic control audio transcript. No photographs were taken because the cockpit camera was not loaded at the time. The radar data remains the strongest corroborating element because it was recorded independently of the visual reports.
Subsequent reviews of the radar film by FAA technical staff ruled out equipment malfunction. The return appeared on both primary and secondary radar systems, indicating a physical object rather than an electronic ghost.
Cultural and Media Impact
The incident received coverage in Japanese and American newspapers shortly after the flight. Captain Terauchi appeared on several television programmes and later wrote a book detailing his experience. The case continues to be cited in discussions of pilot-reported unidentified aerial phenomena because of the quality of the documentation.
Aviation authorities in both countries have since updated guidance on reporting unidentified traffic. Modern systems now encourage crews to file reports without fear of professional repercussions, partly because of high-profile cases such as JAL 1628.
Ongoing Questions
More than thirty years later the precise nature of the objects remains unresolved. No conventional aircraft or natural phenomenon has been identified that matches all recorded details. The combination of multiple trained observers, radar confirmation and absence of prosaic explanations keeps the case open within serious research circles.
Conclusion
The JAL 1628 encounter stands as one of the better documented pilot reports of unidentified aerial phenomena. Its value lies in the convergence of visual testimony, radar data and official records rather than in any single dramatic claim. Further archival research into similar incidents may clarify whether such events represent rare atmospheric effects, misperceptions or something more unusual. Continued open reporting by commercial crews offers the best prospect for accumulating comparable data.
