This document is a memorandum from the U.S. Department of Transportation's Federal Aviation Administration regarding the sighting of unidentified air traffic by the crew of Japan Airlines flight 1628 on November 17, 1986. It is intended for distribution among regional facility managers and staff officers.

This document contains selected materials related to the FAA investigation of Japan Air Lines flight 1628, which reported an unidentified aerial phenomenon on November 17, 1986. It includes transcripts of interviews with the flight crew, statements from air traffic controllers, and explanations regarding uncorrelated radar signals.

The document discusses the radar data related to Japan Airlines flight 1628, which experienced uncorrelated radar signals during its flight on November 17, 1986. FAA experts analyzed the radar data and explained the phenomenon of uncorrelated targets, emphasizing that this occurrence coincided with a pilot's sighting of an unidentified object.

On November 17, 1986, Japan Airlines Flight 1628, a Boeing 747 cargo flight, reported an unidentified traffic at its altitude during its flight from Keflavik, Iceland to Anchorage, Alaska. The traffic was visible on the aircraft's weather radar and was tracked by air traffic control. The unidentified object remained in proximity to the aircraft during maneuv…

The document discusses the phenomenon of uncorrelated radar returns from aircraft, specifically detailing the differences between primary radar signals and secondary transponder signals.

The FAA acknowledges its lack of resources and mandate to scientifically investigate UFO sightings, specifically referencing Japan Airlines flight 1628.

A Japan Air Lines pilot reported seeing a UFO over Alaska, which was later attributed to the bright planet Jupiter and possibly Mars by UFO expert Philip Klass. The pilot, Capt. Kenju Terauchi, disputed this explanation, claiming the object moved with him during his flight.

This document is a record of an interview conducted with JAL Captain Kenju Terauchi regarding his sighting of an unidentified flying object (UFO) on November 17, 1986. The interview was part of an investigation by the FAA to gather first-hand witness testimony.

This document details an interview conducted with a flight engineer regarding a UFO sighting by Captain Terauchi on November 17, 1986. The engineer describes seeing clusters of lights that were larger than navigation lights, with colors ranging from white to amber, and notes that the sighting lasted approximately 10 minutes.

This document is a record of an interview conducted with JAL Captain Kenju Terauchi regarding his sighting of an unidentified flying object (UFO) on November 17, 1986. The interview, conducted by Inspector Richard O. Gordon and interpreter Frank Fujii, details the captain's experiences and observations of the UFO, including descriptions of its appearance, be…

This document is a response from the FAA regarding a request for information about the unidentified traffic sighting by Japan Airlines flight 1628 on November 17, 1986. It includes an order form for obtaining materials related to the investigation.

An interview with JAL flight engineer Yoshie Tsukuba regarding a UFO sighting on November 17, 1986, conducted by FAA representative Pete Beckner.

This document is a computer printout from the FAA regarding radar data related to Japan Air Lines Flight #1628, which reported unidentified flying objects (UFOs) during its flight on November 17, 1986.

The document discusses the phenomenon of uncorrelated radar signals, specifically the differences between primary radar returns and secondary beacon returns when tracking aircraft.

The document appears to be a technical report or data log related to unidentified aerial phenomena (UAP) with various numerical readings and coordinates. The content is heavily encoded and lacks clear context, making it difficult to interpret without additional information.
