The Encounter

The encounter involves Captain Kenju Terrauchi, a pilot of Japan Airlines Flight 1628, who experienced a UAP sighting while flying near Anchorage, Alaska, on November 17, 1986. During the flight, he noticed two strange lights that maneuvered closely in front of his aircraft. As he reported the sighting to air traffic control, the lights vanished and were replaced by a massive object that he described as a gigantic spaceship. After the incident, air traffic control confirmed the presence of a large unidentified object on radar. The encounter led to an FAA investigation, but Terrauchi faced consequences for speaking to the media about his experience. The incident significantly impacted his career and raised concerns about UAP encounters among pilots.
