The Sighting

On the evening of November 17, 1986, Japan Air Lines Flight 1628, a cargo flight operating a Boeing 747-200F, was en route from Paris to Tokyo, with a scheduled stopover in Anchorage, Alaska. The aircraft, transporting various goods including a notable shipment of Beaujolais wine from France, was cruising at an altitude of 35,000 feet over the northern Pacific when an extraordinary encounter unfolded.

At approximately 5:00 PM local time, Captain Kenju Terauchi, who was piloting the aircraft, noticed an unusual light off the right side of the cockpit. Initially perceived as a distant aircraft, the light soon revealed itself to be something far more enigmatic. As the crew, including First Officer Takanori Tamiya and Flight Engineer Yutaka Sato, observed the object, they saw a massive, glowing, rectangular-shaped craft, which they described as being significantly larger than their Boeing 747.

The UFO was reported to be enormous—approximately twice the size of an aircraft carrier. Captain Terauchi made a drawing of the object, depicting it as a giant walnut-shaped craft with pronounced bulges above and below a wide, flattened brim. The object was so large that Flight 1628 seemed minuscule in comparison. The craft was characterized by a series of bright lights along its edges, creating an intense glow that illuminated the surrounding sky.

In addition to the large UFO, the crew observed two smaller unidentified objects that appeared to be moving in conjunction with the larger craft. These smaller objects, while not appearing on radar, were described as being smaller than the cargo plane. They seemed to be flying parallel to the 747 and then suddenly approached very close to it.

The large UFO followed Flight 1628 for nearly 50 minutes. During this period, it performed complex maneuvers, including sudden accelerations and decelerations, demonstrating advanced propulsion capabilities. The object appeared to move in close proximity to the cargo plane, altering its speed and direction in ways that were difficult to explain with known technology. At times, the UFO flew alongside the 747, and at other times, it moved ahead before reappearing in a different position.

Captain Terauchi, with over 29 years of flying experience, and his crew requested and received FAA permission to take evasive action. They executed a series of maneuvers, including a significant altitude drop of 4,000 feet and a complete 360-degree turn, in an effort to avoid any potential collision with the UFO. The flight crew remained in constant communication with Anchorage Air Traffic Control (ATC) and followed their directives throughout the encounter.

The UFO sighting was confirmed by radar data from both the FAA and the U.S. Air Force. Radar operators tracked the large unidentified object, verifying the crew’s observations. The radar also indicated the presence of the large craft moving in proximity to Flight 1628, lending credibility to the crew’s visual reports. However, the smaller objects did not appear on radar, which added another layer of mystery to the encounter.

Despite the unusual nature of the encounter, the crew remained professional and focused. FAA investigators later confirmed that Captain Terauchi and his colleagues were “normal, professional, rational” and had no involvement with drugs or alcohol. The crew’s primary concern was to safely navigate the flight path while avoiding the brightly lit UFO. Captain Terauchi, who later humorously speculated that the UFO might have been interested in their shipment of Beaujolais wine, expressed that the experience was “unbelievable” and acknowledged the skepticism some of his peers had about the sighting.

After the UFO disappeared from view, Flight 1628 continued its journey to Anchorage without further incident. Upon landing, the crew filed a comprehensive report of the encounter, which led to a detailed investigation by Japan Air Lines and U.S. aviation authorities. The sighting garnered significant media attention and was included in various UFO research and investigation archives.

The Japan Cargo 747 sighting stands as one of the most significant UFO encounters in aviation history, distinguished by its combination of detailed eyewitness testimony, corroborative radar data, and the credible professional background of the crew. The precise nature of the object and the reasons behind its behavior remain subjects of ongoing speculation and investigation, making it a landmark case in the field of UFO research.

Possible Explanations

The Japan Cargo 747 UFO sighting remains one of the most intriguing and well-documented UFO encounters in aviation history. Despite the extensive evidence and credible eyewitness testimony, several possible explanations have been proposed to account for the observed phenomena. Here, we explore some of these explanations, assessing their plausibility in the context of the incident.

One possible explanation is that the sighting could be attributed to unusual atmospheric conditions. Phenomena such as rare types of atmospheric reflections, ice crystals, or atmospheric optical effects can sometimes create visual distortions that might be mistaken for unidentified flying objects. For instance, the "luminous" effect described by the crew could potentially be explained by light refraction through ice crystals in the atmosphere. However, this explanation is challenged by the radar confirmation and the detailed observations of the craft's shape and maneuverability, which are less consistent with typical atmospheric phenomena.

Another explanation is that the object could have been a secret or experimental military aircraft. During the 1980s, several countries, including the United States, were testing advanced aerospace technologies that might have been unfamiliar to commercial pilots. The large size and advanced maneuverability of the object described could potentially match experimental aircraft characteristics. However, the fact that the UFO’s radar signature did not align with known military aircraft and the unusual maneuvers performed make this explanation less likely. Furthermore, no military exercises or secret aircraft testing in the region were reported during the time of the sighting.

The possibility that the object was space debris or a malfunctioning satellite has also been considered. Space debris re-entering Earth’s atmosphere can sometimes produce bright, moving lights. However, space debris typically does not exhibit the controlled maneuvering described by the flight crew. Additionally, the size of the object—reported to be twice the size of an aircraft carrier—far exceeds the dimensions of any known space debris or satellite, making this explanation less plausible.

A more conventional explanation could be the misidentification of another aircraft. For instance, if a military or large commercial aircraft was operating in the vicinity, it might have been seen as an unusual object due to its lighting or position relative to the 747. However, the radar data corroborates the crew's sighting of an unidentified object, and the presence of two smaller objects not appearing on radar adds complexity to this theory. Additionally, the detailed description of the UFO’s shape and its interactions with Flight 1628 suggest a phenomenon beyond conventional aircraft.

Finally, the sighting could represent an encounter with a technology or phenomenon that is currently unknown or not understood. The described behavior of the UFO—its size, illumination, and ability to maneuver—suggests a level of technology or natural phenomenon that is not yet recognized by current scientific understanding. This explanation embraces the possibility that the object was an advanced or extraterrestrial craft, reflecting the limits of current technological and scientific knowledge.

Although less likely given the credibility of the witnesses and corroborative radar data, the possibility of a hoax or misreporting cannot be entirely ruled out. However, given the professionalism of Captain Terauchi and his crew, as well as the subsequent investigation by FAA and Japan Air Lines, this explanation is considered improbable. The consistent and detailed reports from the crew, along with radar validation, support the likelihood that the sighting was a genuine, unexplained event.

While each of these explanations presents a different perspective on the Japan Cargo 747 UFO sighting, none fully account for all the details of the encounter. The combination of credible eyewitness testimony, corroborative radar data, and the nature of the observed phenomena makes the sighting a complex case that continues to elude definitive explanation. As with many UFO encounters, the incident remains a subject of interest and speculation within the field of aerial anomaly research.
