… radar data related to Japan Airlines flight 1628, which encountered uncorrelated radar signals during its flight on November 17, 1986. FAA experts explain the phenomenon of uncorrelated primary and beacon targets and its implications for radar tracking.

The document discusses the phenomenon of uncorrelated radar signals, specifically detailing the differences between primary radar returns and secondary beacon returns. It includes a diagram illustrating how these signals can appear on a radar screen when they do not match up in time or location.

This memorandum from the Federal Aviation Administration discusses the radar split image phenomenon observed during JAL flight 1628 on November 17, 1986. It acknowledges the interpretation provided by the Alaskan Region Air Traffic Division and includes an analysis of uncorrelated primary and beacon targets.

This memorandum from the FAA discusses the radar analysis related to JAL flight 1628, specifically addressing the phenomenon of 'split images' observed during the flight on November 17, 1986.

A cargo aircraft captain reported seeing irregular pulsating lights that he believed to be a UFO while flying over Alaska. The FAA concluded that the lights were likely caused by atmospheric conditions.

Captain Terauchi of Japan Airlines Flight #628 reported sightings of unusual lights while flying over Alaska on January 11, 1987. The lights appeared at different positions relative to the aircraft and were later attributed to village lights obscured by atmospheric conditions.
