Kenju Terauchi
Captain Terauchi reported seeing unusual lights and a large object during JAL Flight 1628 over Alaska.
Who this witness was
Kenju Terauchi was captain of Japan Air Lines Flight 1628 during its cargo flight over Alaska in November 1986. His cockpit position gave him direct access to the visual observation and to real-time communication with air-traffic control.
What is attributable to this witness
Terauchi described lights and a larger object near the aircraft. His testimony is first-hand for what he saw from the flight deck; estimates of size, distance and manoeuvre depend on uncertain range and later reconstruction.
- He gave the strongest and most detailed cockpit description in the case.
- Terauchi described pacing lights and later a much larger object near the aircraft.
- His testimony became the focal point of both support and skepticism around the incident.
How the account entered the record
The timing and form of a statement affect what it can establish. Contemporary records and independently preserved material normally carry more weight than later recollection.
- The crew discussed the observation with Anchorage control while airborne, creating a dated operational record.
- FAA material and later interviews preserve the captain's narrative, but public summaries often blend it with contested radar interpretations.
- His later detailed descriptions should be checked against cockpit communications and post-flight records, rather than treated as a substitute for the missing complete sensor package.
Evidence Analysis
Directness and access
He was a direct visual observer during the flight and can describe cockpit conditions, but he did not personally operate every ground radar system cited later.
Relevant expertise
Commercial command experience is highly relevant to aircraft and lighting recognition, while unfamiliar targets at unknown distance still defeat unaided scale estimates.
Consistency
His major visual claims recur, but the strongest performance language appears in a record that includes subsequent interviews and discussion.
Independent support
Other crew members and contemporaneous controller contact support a real report, although they did not necessarily share an identical view or interpretation.
Limits and alternative readings
Released public material does not provide a complete calibrated sensor package, and astronomical, traffic and geometry questions remain essential.
Record cautions
- Some later analyses argue Terauchi interpreted ambiguous visual stimuli too confidently.
Reasoned conclusion
Terauchi provides experienced, named cockpit testimony for an unusual aviation report. It carries real weight for the report's occurrence, but the available public record cannot settle target range, physical dimensions or origin from testimony and partial radar discussion alone.
Associated Case Research
Other witnesses in the record
These links identify people or groups associated with the same case. Their accounts should be assessed independently before being treated as corroboration.
Methodology
UAPRAD witness dossiers separate a person's own reported role from case retellings, later commentary, and claims made by other people. Directness, expertise, consistency, corroboration, limitations, and cited source quality are evaluated independently.

Sources are ordered toward official records, contemporary material and institutional archives. Inclusion documents the record; it does not mean the publisher endorses every reported interpretation.
