Black triangles are a class of unidentified flying objects with certain common anti-gravity and stealth technology features, believed by many to be a top secret covert black project at the highest levels of government. Black triangles have been first observed by witnesses starting around the late 1980's. Reports generally describe a class of silent black triangular UFOs hovering or slowly cruising at low altitudes over cities and highways capable of reaching supersonic speeds in a blink of an eye. Sightings usually take place at night. These UFO Sightings are often described having bright lights that appear at each corner of the triangle and a pulsing ball of red light in the center of the craft, they also appear to be under intelligent control/A.I. technology. Unidentified flying Black triangles were detected by radar flying low in Belgium commanded airspace During the 1989-1990 Belgian UFO Sighting wave, two Belgian Air Force F-16's attempted to intercept the unidentified flying triangle detected by radar, but the UFO Sighting outmaneuvered the F-16's and escape at supersonic speeds. The pilots did not report seeing the object, they were only able detect and lock on to it on radar. credit I.Lopez
