About this episode

This episode investigates the mysterious Japan Airlines Flight 1628 UFO case over Alaska, exploring pilot accounts, radar data, and various explanations.

In 1986, Japan Airlines Flight 1628 was flying over Alaska when the crew reported unknown traffic near their Boeing 747. Captain Kenju Terauchi and his crew described objects moving near the aircraft. Anchorage air traffic control treated it as a real-time aviation concern. Radar was discussed. Military coordination entered the picture. Other aircraft were asked to look. Then, after landing, the story changed. What sounded urgent in the sky became much smaller on paper. In this episode of Divergent Files, we investigate the JAL 1628 case through pilot testimony, FAA records, air traffic control details, radar uncertainty, military involvement, and skeptical explanations involving Jupiter, misidentified lights, radar clutter, and pilot error. This is not proof of alien visitation. But it is not nothing, either. It is one of the strangest aviation UAP cases ever recorded… and the record still refuses to sit down.
