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.

Many people in this world are interested in paranormal things, but most of them don’t consider the UFO’s as they simply can’t believe the existence of such objects. Following is another report of an alleged UFO sighting, this time by a Russian scientist living in Russia. Because of nature of his work, he was asked to remain anonymous.

The incident happened on 13th June 1980. He was returing home after seeing of his relatives. He took the last bus from the train station located at the Dolgoprudny which is situated near the northern border of Mexico. Dolgoprudny is a well known town in Russia and also houses Moscow Physics Technical Institute.

Just after he came out of the bus, he looked at his apartment. What he saw then was really amazing. At first he thought that his apartment was on fire as very bright lights and flashes were coming out from it. The next moment he saw a fling saucer moving very silently, almost parallel to the surface. According to him, the UFO moved for a while in the same direction. After several minutes, it suddenly changed its directions and speed of movement in the new direction which was about 90 degree angle to the precious one was incredible.

He made certain observation. First, the UFO was not transparent, because when it covered the stars, he was not able to see them. Second, there was some sort of gas stream which was coming out of the UFO. The gas stream was coming out from entire surface of the UFO.

He estimated that the UFO was around 30-45 meters in diameter and was emitting heavy or brilliant flash lights.

The event was also seen by a pilot and he reported the matter to ATC at Sheremetyevo International Airport that he was seeing “a space ship from another planet.”

To the scientist’s surprise none of the government agencies or helicopters came to take the samples of the colored gas clouds that existed for a good period of time, even after the UFO disappeared. More than that, after many days one of the central newspapers published an article on the event. The newspaper published an article report on the pilot experience that day saying how deceptive “natural phenomena” or “military landing missiles” can be even for experienced pilots. The official reports that followed said that it was not an UFO but a Russian satellite.

Now many questions arise like, would a satellite make a 90 degree turn in the sky and still move? Why did the Russian newspaper labeled this pilot's report of a UFO as "natural phenomena" or "military landing missiles"?
