Philip J. Klass, a technical journalist, discusses his investigation into a UFO sighting, suggesting that Jupiter was initially misidentified as a UFO during a flight. He expresses interest in giving a lecture to FAA controllers to clarify common misconceptions about UFOs.

This document is a correspondence from Philip J. Klass addressing questions related to a flight path and a potential UFO sighting by a pilot. It discusses the timing of a flight maneuver and the accuracy of the pilot's memory regarding his flight route.

The document is a white paper summarizing the Japan Air Lines (JAL) UFO incident that occurred on November 17, 1986. It discusses the initial media coverage, FAA investigations, and analysis of radar data related to the incident.

This document discusses a UFO sighting reported by the crew of a Japan Airlines flight on November 17, 1986. The pilot, co-pilot, and flight engineer observed a stream-like radar target that was interpreted as a UFO, which was later suggested to be an echo from ice crystals. The FAA made data regarding the incident available, countering claims of government …

This document appears to be a transcript of an interview regarding a sighting of an unidentified aerial phenomenon. The interviewee expresses certainty about having seen something that resembled an oncoming aircraft, but details are sparse.

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.

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

This document is a memorandum from the Federal Aviation Administration discussing radar targets associated with JAL flight 1628 and the phenomenon of 'split images' observed during the flight.

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

This document appears to be a transcript of an interview regarding a sighting of an unidentified aerial phenomenon. The witness expresses certainty about seeing something that resembled an oncoming aircraft, although details about the sighting are limited.

This document details two incidents of unidentified air traffic sightings reported by flight crews in Alaska in January 1987. The first incident involved an Alaska Airlines Boeing 737 that detected a fast-moving target on its radar, while the second incident involved a Japan Airlines Boeing 747 pilot who reported unusual lights in front of his aircraft.

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.

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.

This document discusses the analysis of 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.
