JAL Flight 1628 - Full Account

Captain Kenju Terauchi had flown for Japan Airlines for 29 years without incident. On November 17, 1986, an encounter over Alaska ended his distinguished career and demonstrated just how threatening UFO witnesses can be to their own lives and livelihoods.

The Encounter Begins

JAL Flight 1628, a Boeing 747 cargo jet carrying French wine from Paris to Tokyo via Anchorage, was cruising at 35,000 feet over northeastern Alaska when Captain Terauchi and his crew noticed lights below and to the left of their aircraft. At first, they assumed it was military traffic - the area saw frequent Air Force activity.

But the lights weren’t behaving like any aircraft. They paced the 747 for several minutes, then suddenly moved directly in front of the cockpit, startling the crew with their brilliant illumination. Terauchi described two rectangular arrays of lights, each appearing to glow with what he called the intensity of jet exhaust. The cockpit was so brightly lit that he could feel warmth on his face.

The Mothership

What happened next elevated the sighting from unusual to extraordinary. As the initial objects moved away, an enormous dark mass became visible behind the 747. Terauchi, struggling to describe what he was seeing, estimated the object to be the size of two aircraft carriers. It was walnut-shaped and massive beyond anything he had ever seen in nearly three decades of flying.

The object paced the aircraft for nearly 50 minutes, sometimes moving alongside, sometimes behind. Throughout the encounter, Terauchi maintained professional communication with FAA air traffic control in Anchorage, who confirmed that they were also tracking an unidentified return near his position.

The Investigation

The FAA conducted a thorough investigation. Officials interviewed all three crew members, obtained radar data, and reviewed communication transcripts. The internal conclusion was that Terauchi was credible and something genuinely anomalous had occurred. But when the story leaked to the press, the agency’s public position shifted dramatically.

Initial FAA findings supported the crew’s account. After media attention, the agency began suggesting “ice crystals” and misidentified planets. Captain Terauchi was removed from his flight duties. JAL reassigned him to a desk job.

The Cost

Terauchi paid dearly for his honesty. Despite having an impeccable record, despite the radar confirmation, despite the other crew members supporting his account, he was effectively punished for reporting what he saw. His subsequent career was spent behind a desk rather than in a cockpit.

The JAL 1628 case illustrates a pattern that researchers have documented repeatedly - credible witnesses who report UFO encounters often face professional and personal consequences. This chilling effect undoubtedly keeps countless other witnesses silent, raising the question of how many similar incidents go unreported every year.

The Crew and the Radar Picture

Captain Terauchi was joined in the cockpit by First Officer Takanori Tamefuji and Flight Engineer Yoshio Tsukuba, both of whom corroborated significant aspects of the encounter, though Tamefuji noted that he could not personally see all the elements Terauchi described. The radar picture from the Anchorage Air Route Traffic Control Center was particularly striking, with controller Carl Henley reportedly observing returns near JAL 1628 that appeared and disappeared in a manner inconsistent with conventional traffic. Anchorage controllers offered to vector a nearby United Airlines flight and a military C-130 toward the position to obtain corroboration, but by the time these aircraft were close enough to investigate, the unidentified objects had departed. Henley’s recorded communications during the encounter, later released through Freedom of Information Act requests, document the calm professionalism of all parties throughout an extraordinary fifty minutes.

Conventional Explanations

In the years since the encounter, several skeptical analyses have attempted to explain the JAL 1628 sighting in conventional terms. Astronomer Philip Klass, a longtime UFO skeptic, proposed that the lights observed by the crew were the planets Jupiter and Mars, possibly distorted by ice crystals in the cold Alaskan atmosphere. Others have suggested that the radar returns may have been atmospheric ducting artifacts or split returns from the JAL aircraft itself reflecting off ice in the air. The FAA’s own retraction of its initial supportive findings reflected institutional pressure rather than fresh technical evidence, and Captain Terauchi rejected the planetary hypothesis emphatically, noting that no celestial object could pace an aircraft for nearly an hour or appear directly in front of his cockpit at close range. The size and behavior of the objects he described remained inconsistent with any accepted natural explanation.

Lasting Influence on UAP Research

The JAL 1628 case has retained a significant place in the UAP research record because of the unusual confluence of credible witnesses, professional radar tracking, and prolonged duration. It is frequently cited in discussions of pilot testimony and was referenced during the 2021 Office of the Director of National Intelligence preliminary assessment as part of the broader history of unexplained aviation encounters. The eventual establishment of formal reporting procedures within the United States military, and later within the Federal Aviation Administration, owes a debt to the lessons of cases like Terauchi’s, in which a willing witness and supporting evidence were nonetheless inadequate to overcome institutional reluctance. Captain Terauchi continued to speak about his experience throughout his life, maintaining until his death in 2010 that what he had encountered over Alaska that November night was real, structured, and unlike anything in his decades of flight experience.
