This document is an aircraft incident record detailing an event involving a Boeing 737 operated by Alaska Airlines on January 29, 1987, near McGrath, Alaska. The report indicates no injuries or fatalities, and the aircraft was involved in a minor incident categorized under general aviation.

This document discusses the FAA's analysis of radar data related to Japan Airlines flight 1628, which experienced uncorrelated radar signals during its flight on November 17, 1986. The FAA experts concluded that the radar system detected an 'uncorrelated primary and beacon target', a phenomenon that can occur under certain conditions, particularly when a pil…

…es has tracked over 3,000 pilot-reported UFO sightings, categorizing them into two main types: objects that appear and disappear rapidly, and those that follow aircraft for extended periods. The document highlights the skepticism from FAA and military regarding radar sightings.

The FAA is forwarding radar tapes and records regarding a UFO sighting reported by Japan Air Lines pilot Kenji Terauchi, who claimed that three lights followed his Boeing 747 cargo jet over Alaska for 55 minutes. Despite radar detection, military officials dismissed the sightings as clutter.

A pilot's report from 1949 details an encounter with an unidentified light during a weather reconnaissance mission over Shemya Air Force Base. The light was observed to move at high speed and did not resemble a meteor.
