Introduction
The crew testimony from Japan Air Lines Flight 1628 is the central human evidence in one of the best-known commercial aviation UFO cases. On 17 November 1986, the three-person cockpit crew of a JAL Boeing 747 cargo aircraft reported seeing unusual lights and a much larger object while flying over Alaska. Their accounts became significant because the witnesses were experienced aviation professionals who made their reports during an active flight, communicated with air traffic controllers, and were later interviewed by the Federal Aviation Administration (FAA).[The Washington Post]washingtonpost.comThe Washington Post UFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADARThe Washington PostUFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADAR - The Washington PostJanuary 1, 1987…
The crew’s statements do not by themselves prove what the objects were, but they remain important because they provide a detailed record of what trained observers believed they saw, how their interpretation developed during the encounter, and why later investigators disagreed over whether the event represented an unidentified physical object or a combination of perception and instrument effects.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
The pilots’ reported observations
The main witness was Captain Kenju Terauchi, commander of JAL Flight 1628. According to FAA interview notes, Terauchi first reported visual contact with unidentified air traffic while the Boeing 747 was cruising at approximately flight level 390. He described objects appearing ahead of the aircraft and later reported that the crew observed bright lights and a larger object accompanying the aircraft. The FAA records identify the other crew members interviewed with him as First Officer Takanori Tamefuji and Flight Engineer Yoshio Tsukuda.[documents.theblackvault.com]documents.theblackvault.comThis document is made available through the declassification effortsThis document is made available through the declassification efforts
Terauchi’s account developed through several phases. The crew initially noticed bright lights that appeared to move near the aircraft. Later, Terauchi described a much larger object that he believed was considerably bigger than the 747 itself. Contemporary reporting quoted him as describing the object as enormous compared with his aircraft, while noting that the two smaller lights he had first observed were not seen on radar.[The Washington Post]washingtonpost.comThe Washington Post UFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADARThe Washington PostUFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADAR - The Washington PostJanuary 1, 1987…
A key feature of the testimony was the reported behaviour of the objects. The crew believed the lights were not simply distant stars or aircraft because they appeared to change position relative to the 747, approach the aircraft, and remain associated with its flight path. The crew contacted air traffic control while attempting to determine whether the objects could be identified as normal traffic.[documents.theblackvault.com]documents.theblackvault.comThis document is made available through the declassification effortsThis document is made available through the declassification efforts
The encounter also placed the crew in an unusual decision-making situation. Rather than simply observing an unexplained light, they were operating a large cargo aircraft in controlled airspace and had to consider whether the reported object represented a collision risk. FAA interview notes recorded that Terauchi was authorised to take action if necessary to avoid the reported traffic.[The Washington Post]washingtonpost.comThe Washington Post UFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADARThe Washington PostUFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADAR - The Washington PostJanuary 1, 1987…
Crew credibility and aviation experience
The credibility of the witnesses is one of the reasons the case attracted lasting attention. The report did not come from a single casual observer on the ground, but from three crew members responsible for operating a commercial aircraft. FAA investigators interviewed the captain, first officer, and flight engineer shortly after the event, preserving their accounts while memories were still recent.[documents.theblackvault.com]documents.theblackvault.comThis document is made available through the declassification effortsThis document is made available through the declassification efforts
Supporters of the crew’s reliability point to several factors: the witnesses were trained to interpret aircraft environments, they reported the event through aviation channels rather than only after publicity developed, and they maintained that their observations involved structured movement rather than a brief unexplained flash. These characteristics led some researchers to treat the case as more significant than ordinary unidentified-light reports.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
However, witness expertise does not remove the possibility of misinterpretation. Aviation professionals are skilled observers of aircraft operations, but night-time aerial observation remains difficult because distance, lighting, atmospheric conditions, and lack of reference points can distort perceptions of size and movement. Skeptical analyses have argued that even experienced pilots can misidentify bright astronomical objects or unusual visual phenomena when judging objects from a moving aircraft.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
The role of the other two crew members is also debated. The strongest descriptions of the large object came from Captain Terauchi, while later summaries of the case often note that the other crew members’ observations were less detailed. Skeptics have used this difference to argue that the case relies heavily on the captain’s interpretation, whereas supporters argue that the overall cockpit observations still represent multiple trained witnesses.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
How the testimony was interpreted
The crew’s account produced two competing interpretations. The first view treats the testimony as evidence of a genuinely unidentified aerial object. Supporters argue that the combination of three professional witnesses, contemporaneous radio communication, and reported radar involvement makes the case unusual. In this interpretation, the most important point is not that the crew identified the object, but that experienced observers reported a sustained encounter that they could not explain.[The Washington Post]washingtonpost.comThe Washington Post UFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADARThe Washington PostUFO SIGHTING CONFIRMED BY FAA, AIR FORCE RADAR - The Washington PostJanuary 1, 1987…
The second interpretation focuses on human perception. Skeptical investigators have suggested that the crew may have mistaken bright astronomical objects, such as planets or stars, for nearby objects, while interpreting ambiguous radar information as confirmation. This view argues that the appearance of movement or proximity can be misleading when an aircraft is travelling at high altitude without nearby visual reference points.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
The disagreement centres partly on the difference between a reliable observation and a reliable identification. The crew may have accurately reported unusual lights and their apparent behaviour, while the conclusion that those lights represented a large unknown craft remains an interpretation rather than a direct measurement. This distinction is central to the continuing debate around JAL 1628.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
The lasting significance of the crew accounts
The JAL 1628 testimony remains influential because it illustrates both the value and the limits of eyewitness evidence in aviation-related mysteries. The crew provided a detailed contemporaneous account from inside a commercial aircraft, but the observations were still shaped by the challenges of judging distant objects in the night sky.[documents.theblackvault.com]documents.theblackvault.comThis document is made available through the declassification effortsThis document is made available through the declassification efforts
For researchers studying unidentified aerial phenomena, the case is therefore less about whether the crew should be believed and more about what their testimony can establish. Their statements strongly establish that experienced pilots reported an unusual encounter. They do not, on their own, establish the identity, technology, or origin of the objects observed. The unresolved question is whether the remaining evidence supports an unknown physical object or a more ordinary explanation involving perception and radar interpretation.[The Black Vault]theblackvault.comthe vault files 1986 alaska jal flight 1628The Black VaultThe Vault Files: 1986 Alaska JAL Flight 1628 - The Black Vault Case FilesAugust 25, 2025…
