Case Summary

Japan Air Lines cargo pilot reported massive UFO encounter over Alaska, tracked by military radar and investigated by FAA.

Official Narrative

On November 17, 1986, the pilot of Japan Air Lines Flight 1628 reported visual contact with unidentified aircraft approximately 50 miles northeast of Anchorage, Alaska. Anchorage Air Route Traffic Control Center detected intermittent radar returns consistent with the pilot's reported timeframe. The Federal Aviation Administration conducted a thorough investigation examining radar data, pilot testimony, and weather conditions. While unable to identify the objects, investigators found no evidence of equipment malfunction or pilot error. The case file was classified as unresolved and forwarded to appropriate agencies for further analysis.

Investigation Verdict

Plausible

Captain Terauchi's account gains credibility from his 29 years of flight experience, corroborating radar data from Anchorage control, and the FAA's serious investigation. However, the case remains controversial. Skeptics note that only Terauchi clearly observed the objects while his co-pilot and flight engineer saw ambiguous lights. Some researchers suggest the encounter involved experimental military aircraft or atmospheric phenomena. The temperature inversion conditions present that night could have created optical illusions. Nonetheless, the combination of visual testimony from an experienced pilot, radar confirmation, and official investigation makes this one of the most compelling commercial aviation UFO cases.
