They are black, triangular, have lights, can fly and are completely unidentifiable. This is a UFO. Many people, since the 1940’s, have witnessed the phenomenon known as the “black triangles.” So, what are they? No one knows. These black triangles have been spotted all over the world, but are more commonly reported to be seen in the skies above the Unites States and England. They are enormous and they hover, slowly cruising over cities. They are silent, usually maintain very low altitudes and make no attempt at not being detected. Running lights, either colored or white, are usually located at the triangle’s corners.
Sometimes reports tell of a red pulsating light in the center, as well. There have been no explanations of what these are, as yet and thus their origins, existence and purpose remain a mystery.

It has been speculated that these black triangles are part of an ongoing experiment by the government on hovering technologies. But, because they appear over large cities and make no efforts to conceal their presence, this is highly unlikely. Most reports of black triangles are consistent in describing their size as about 200 feet long and the width of a typical football field. They tend to appear out of nowhere, hover in place about 100 feet above the ground and sometimes even land.

A famous reporting of the black triangle UFO sightings was the “Phoenix Lights.” In addition to other UFOs, there were numerous black triangles spotted and videotaped by the people of Phoenix, Arizona and the local media. This event that spanned multiple evenings began on Thursday, March 13, 1997. Lights were seen as low as 1000 feet in the air and were moving at speeds that were far too slow to be conventional aircraft.
They produced no sound and several of them grouped into a “V” formation which lingered above the city. A lot of witnesses reported a triangle that was over a mile wide and blocked out the stars as it passed over their homes. There were other reports of similar craft sighted in the skies above Las Vegas, Nevada and Los Angeles, California.

The air force officially reported the incident as a testing of flares that were launched out of conventional aircraft at the time. Witnesses did report seeing the military jets, but that they were chasing the mysterious objects and not launching flares. Over the course of the next few nights, local pilots attempted to recreate the event by flying propeller planes in “V” formation. The engine noise was easily heard.

Three years earlier near Moscow, Mach 12, 1990, there were several groupings of the UFOs in the night sky. There were some spheres and discs, as well as the triangular craft. Local people spent their nights watching from their rooftops as the silent objects darted through the sky. Several accounts of this incident were retained by the CIA, although none were released for the public.

So, what are these mysterious black triangles? Are they alien craft? Are they air force flares or the government testing of new technologies? You be the judge.

Only slightly less common than the ubiquitous saucer shapes are the unidentified flying objects that appear to be perfectly round spheres. In size the sphere objects have been observed to be as small as one meter in diameter up to huge flying balls that are estimated as well over one hundred meters across. In daylight they tend to look silvery, as though made of some polished steel or aluminum. These spheroid craft are often described as giant flying ball bearings. In the twilight or nighttime sky a glowing orange or reddish light seems to emanate from them. A few reports state seeing either a small row of "windows" or possibly a narrow rim around the equator of these spheres.

As with the saucer craft, the spheres are highly maneuverable and can go from a hover to supersonic speeds in an instant. Despite the extreme speeds they have been observed obtaining, the spheres generate neither sound nor create a sonic wake in their passing. Quite often these strange round objects are traveling at a very sedate speed as though they have nothing to fear and all the time in the world to get wherever they are going. During World War II, allied pilots often reported having what they called "foo fighters", small luminous spherical orbs about a meter across, keep pace with their aircraft as they flew over combat zones.

Small spheres have been seen to glide over fields where crop circles subsequently appear. They have been observed around sunset to come in from very high, occasionally leaving a short-lived corkscrew-like trail of ice vapor in their wake. Many of the anomalous sightings filmed by various space missions on the Space Shuttle flights and from the International Space Station appear to be these round sphere-shaped UFO's. They are often seen to be gliding along above heavy thunderstorm clouds.

Another strange quality exhibited by the spheres is their seeming ability to simply vanish. They have been observed to just slowly fade out of existence as though somehow either phasing through a dimensional shift or possibly reverting to an invisible state. If, as has been speculated, these craft employ a powerful electro-magnetic anti-gravity engine then the perfectly round shape is understandable. A sphere is the perfect shape for such a device to use. It is through this lack of understanding that the Philadelphia Experiment, as allegedly undertaken by our own Navy, went so horribly wrong.

Despite the thousands of reports of unidentified flying objects made yearly around the world, there are a few commonalties in the sightings. Regardless of shape, many UFO's give off their own luminescence. This is thought to be caused by ionization of the air surrounding the surface or possibly vents on the craft. It is believed to work similarly to what occurs inside a neon light tube. This is usually of an orangish or yellow color when seen at night. It also explains the hazy, wavering appearance of UFO's during daylight.

By far the most common shape of a UFO is the ubiquitous "saucer" or "disk" shape. Often the craft will appear to have a flat bottom or a slightly convex hollow. These are the one's described as "hubcaps". Occasionally there will be a more pronounced upper hemispherical shape. A type of dome or "transparent cockpit" shape is reported on the top of the round, spinning craft. These "classic" flying saucers are the usual model for cartoons containing "little green men".

Other saucers show a less detailed shape. Many reports come in about the lenticular saucers that appear to be two shallow bowls glued together at the rim. They are usually dark, greyish to black and, like the 2006 O'Hara Airport sighting in Chicago, USA, can be described "like an M&M candy".

The "straw hat" flying saucers are generally described as being like a coin with a rim. Rising above this edge is usually a secondary superstructure that gives them their distinctly hat-like appearance. They have occasionally been reported as looking like two hats glued together at the rim. The bottom and top of these craft are generally very noticeably flat.

Falling into this category is also the anomalous "mushroom" shaped UFO's like the alleged "Gulf Breeze, Florida saucer. The bell-shaped saucers also fit here along with the ones that have been described as "an upside down coffee cup in a saucer".

These are generally the most maneuverable of all the unknown flying objects. They seem to be able to defy not only gravity but motion, speed and inertial forces as well. While they are known to hover quite well, they also are known for such amazing maneuverability as to rip a conventional craft to bits. They are usually described as rotating or spinning along their horizontal axis when seen close enough to detect the motion. On can only assume it is merely the outer rim that spins while the central core containing possible pilot and crew remains stable.
