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.

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

This document is a memorandum from the Federal Aviation Administration (FAA) regarding the radar images of Japan Air Lines flight 1628, which experienced intermittent radar images attributed to 'split images'. The FAA seeks clarification on this phenomenon for public communication.

The document discusses the phenomenon of uncorrelated radar signals, explaining the differences between primary and secondary radar returns and how they can indicate the presence of an aircraft.

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.

The document discusses the phenomenon of uncorrelated radar signals, explaining how primary and secondary radar returns can occur at different times, leading to discrepancies in radar tracking of aircraft.

The document discusses the phenomenon of uncorrelated radar signals, explaining the differences between primary and secondary radar returns and their implications for radar tracking of aircraft.

This document details two incidents of unidentified air traffic sightings reported by flight crews of Alaska Airlines and Japan Airlines in January 1987. Both sightings involved unusual radar targets that could not be visually confirmed by the pilots.

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.

The FAA states it lacks the resources and mandate to scientifically investigate UFO sightings, including the case of Japan Airlines flight 1628. They have completed their investigation and do not intend to pursue it further.

On January 29, 1987, the crew of Alaska Airlines flight #53 reported an unidentified object on their weather radar while flying at 35,000 feet. Despite checking with air traffic control and the USAF, no other aircraft were identified in the vicinity.

The document discusses a UFO sighting reported by Japan Air Lines pilot Kenju Terauchi over Alaska on November 17, which was partially corroborated by FAA radar data. The FAA released a data package including transcripts and interviews, revealing insights into the incident and the pilot's previous UFO sightings.

On January 29, 1987, the crew of Alaska Airlines flight #53 reported an unidentified target on their weather radar while flying at 35,000 feet. Despite checking with air traffic control and the USAF, no other aircraft were identified in the area.

This document discusses the unusual visual and radar sighting reported by the crew of Japan Airlines Flight 1628 on November 17, 1986. The communication details observations made by the flight crew, including descriptions of lights and radar readings, and requests for further information.

This document is a personnel statement from the Federal Aviation Administration (FAA) regarding an incident involving aircraft JL1628 on November 18, 1986. The report details the communication between air traffic control and the aircraft as it encountered an unidentified object in its vicinity.

On January 29, 1987, Alaska Airlines Flight 53 reported an unidentified target on their weather radar while flying at 35,000 feet near McGrath, Alaska. The target moved rapidly and was not visually confirmed by the crew. FAA and USAF investigations found no other aircraft in the area.

The FAA released findings regarding a UFO sighting by a Japanese Airlines crew on November 17, which included first-person testimonies and radar data, but ultimately concluded that there was no confirmed UFO sighting.

On November 17, 1986, a JAL B747 cargo flight reported an encounter with an unidentified object displaying unusual strobe lights while flying over the North Pole. The incident was corroborated by radar data from both civilian and military sources, but no further information about the object was determined.

The FAA is offering a package of materials related to a UFO sighting reported by a Japan Air Lines pilot, which includes audio tapes, interviews, and documentation, in response to public interest.

A Japan Air Lines 747, piloted by Kenju Terauchi, encountered three UFOs during a flight over Alaska, with one UFO described as being larger than two aircraft carriers. The FAA initially confirmed radar tracking of the UFOs but later retracted the statement, attributing the radar blip to a duplicate image of the 747. Eyewitness accounts from the flight crew …
