The inquiry into the reported sighting of an unidentified flying object over Alaska was reopened. Federal Aviation Aministration investigators were reinterviewing the pilot of a Japan Air Lines cargo flight, Capt. Kenju Terauchi, and reviewing records from Nov. 17, when a mysterious blip appeared on radar screens and the JAL crew said they saw strange lights in their flight path. After evasive action recommended by the FAA was taken, the lights reportedly followed the plane for about 400 miles. Paul Steucke of the FAA said the incident was being investigated as a violation of air space, but added that "no one considers it realistic that we can identify the object."
