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.

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.

This document discusses the FAA's analysis of radar data related to Japan Airlines flight 1628, which reported an uncorrelated radar target during its flight on November 17, 1986. The FAA experts explained the phenomenon of uncorrelated primary and beacon targets and its implications for radar tracking.

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.

This document is a memorandum from the U.S. Department of Transportation's Federal Aviation Administration discussing the radar targets associated with Japan Airlines flight 1628, which experienced unusual radar phenomena on November 17, 1986. It addresses the interpretation of 'split images' on radar and includes an analysis by Dennis Simantel.

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.

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.

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…

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.

The FAA has reopened its investigation into unidentified flying objects (UFOs) reported by a Japan Air Lines crew over Alaska on November 17, 1986. The inquiry aims to identify an unknown object that appeared on radar and was seen by the crew, which was initially dismissed as 'random clutter.'

A Japan Air cargo plane reported strange flashing lights while flying over northern Alaska, prompting concern from the crew. The FAA stated they are not investigating the incident, as there is nothing to investigate, while the military has not provided any information.

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.
