On November 17, 1986, a Japanese Boeing 174-200F cargo aircraft, Japan Airlines (JAL) Flight 1628, was flying through the mysterious Alaska Triangle and just over Anchorage on its return from Paris. The crew included Captain Kenju Terauchi, an ex-fighter pilot with more than 10,000 hours flight experience; co-pilot 1st Officer Takanori Tamefuji; and flight engineer Yoshio Tsukuba.
At 17:11, while flying at 35,000 feet, Captain Terauchi noticed what appeared to be the presence of some additional traffic in his vicinity. At first, he thought the lights were military jets on a special mission, since they were so close to the area. However, when the lights had not changed course, he realized they were something else; something that would continue to follow them for about 400 miles.
Suddenly, the crew encountered two UFOs to their left. One of the objects appeared to be twice the size of the aircraft, while the other was smaller. They also reported seeing flashing lights following the plane. Captain Terauchi described them as flying as if there was no such thing as gravity. They would speed up quickly, stop, and then fly at the plane's speed. The next instance, they changed course as though they had overcome gravity, which was impossible for a normal plane to do.
At 1719, Captain Terauchi notified Anchorage air traffic control. At this point, the UFOs were being tracked on both military and civilian radar and verified by a high-level administrator in the Federal Aviation Administration (FAA). In an attempt to elude the UFOs, the pilot requested permission from the ground crew to fly at a lower altitude and drop 4,000 feet. However, even after making several attempts, he could not elude them. Upon flying over Fairbanks, the city lights helped illuminate the object, to which he referred to as the "Mother Ship." The encounter continued to last about 50 minutes before the UFO suddenly disappeared.
Detailed reports by the military controller indicated that the UFOs had been traveling thousands of miles per hour as they maneuvered in the airspace around JAL 1628.
Located on an ancient seabed in the southern part of the Chihuahua Desert, separated by low mountain ranges is Bolsom de Mapimi. It is said there is a strange magnetic condition about the land causing vortices to form that stretch into the upper atmosphere.
The land contains huge amounts of magnetic and uranium deposits. Some rocks feature an unusual content of rare metals such as ruthenium, rhodium, and a relatively stable isotope Technetium 97, that is radioactive. The area is abundant with physical oddities including abnormally large growth patterns in the vegetation and wildlife.
In 1964, Harry de la Pena, an engineer, surveyed a thirteen mile stretch of the desert preparing for an oil pipeline that would extend to Jimenez, Chihuahua. During his expedition, his team became frustrated when they continuously failed to maintain proper radio signal that was imperative in order to communicate between team members. They could find no explanation for why this was occurring. He described the area as "the zone of silence."
After the surveying was completed, Harry having great interest in the anomalies that had taken place, returned to investigate some more. Despite returning numerous times in an attempt to repeat the phenomena, he discovered the silent zones were not fixed, but in fact appeared to move around.
Strange encounters and unexplained occurrences appear in the night sky. Among these are glowing orbs and colorful flying triangular shapes. They measure approximately six feet across, have borders of prismatic color, with the inside containing translucent bands of shifting colors. Many times, they appear in a group of three, are equilateral and tilt at a 105-degree angle.
In 1976, the National Institute of Nuclear Energy sent two engineers to the Zone: Ray Cruz and Jorge Aguilera. The study was focused on Hertzian waves and indicated that the horizontal propagation of radio waves was normal. However, the vertical was cut off completely thus causing the phenomenon of "silence." They concluded this anomaly was not a function of position, but of time.
