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 appears to be a technical report or data log related to unidentified aerial phenomena (UAP) from the National Archives, containing various numerical data points and operational parameters.

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.

A report detailing an incident involving Japan Airlines Flight 1628, which was followed by an unidentified object exhibiting extraordinary maneuvers over Alaska, tracked by multiple radar systems.

This document appears to be a technical report containing time-stamped data related to unidentified aerial phenomena (UAP) or unidentified flying objects (UFOs). The data includes coordinates, altitude, speed, and other metrics, but is largely obscured by formatting issues and unclear text.

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.

This document details an encounter involving Japan Airlines Flight 1628, which reported being followed by an unidentified object while flying over Alaska. The crew observed two lights and later described a large, globular craft that seemed to track their flight path. The FAA and military radar confirmed the presence of an object near the flight, leading to c…

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 analysis of radar data related to Japan Airlines flight 1628, which experienced 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.

This document discusses a UFO sighting involving a pilot and the FAA's investigation into the incident. The pilot reported seeing an object that moved in ways inconsistent with known celestial bodies, leading to a debate over the nature of the sighting. The FAA's analysis of radar data was inconclusive, and the document highlights the complexities of interpr…

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.

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.

This document is an aircraft incident record detailing an event involving a Boeing 737 operated by Alaska Airlines on January 29, 1987, near McGrath, Alaska. The report indicates no injuries or fatalities, and the aircraft was involved in a minor incident categorized under general aviation.

This document is a record of articles related to the UFO sighting of Japan Airlines Flight 1628 on November 17, 1986, in Alaska. It lists various newspapers and cities from which articles were sourced, totaling over 54 articles.

This document details a series of UAP sightings reported on January 2, 1987, including various individuals and organizations involved in the reporting and investigation of these sightings.

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 memorandum from the FAA Alaskan Region detailing media inquiries and responses related to a UFO sighting by a Japan Airlines captain in November 1986. It highlights the extensive media engagement and the preparation for a press conference to address public interest.

This document discusses an incident involving Japan Air Lines pilot Kenju Terauchi, who reported encountering strange lights over Alaska while flying a 747. The Federal Aviation Administration and the U.S. Air Force confirmed the presence of a UFO on their radar during this event.

A Japan Air Lines pilot, Kenju Terauchi, recounts a UFO sighting during a flight over Alaska, describing two unidentified objects emitting amber light and exhibiting advanced movement capabilities.

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.'
