Some might have witnessed the incident was also made into photographs. UFO people to make explanations, including:

Many countries around the world to conduct UFO research. UFO monographs on about 350 species, 100 species of various periodicals. Countries in the world have a group of experts to participate in this work. China has also set up a science and technology workers based civil academic research groups - China UFO Research Association. China UFO on the popular science publications "flying saucer exploration," published in 1981.

"China Encyclopedia" and "aerospace" in the formal inclusion of the "UFO" (UFO) entries explained that the candidates writer is the third China UFO Research Association, chairman of Sun-li. "China Encyclopedia" on the UFO explanation reads as follows: UFO without identifying Feihangwu origin from the air. Called on the international UFO, commonly known as the flying saucer. According to eyewitness reports, its appearance more than discoid Chengyuan (disk), and spherical shaped, in the air-or slow-moving.

Some people think that the historical data on UFO records first appeared in the "Bible",. "Old Testament Bible" in the records, the prophet Ezekiel (Ezekiel) saw the first UFO. ( "Bible, the Old Testament Ezekiel" record: "I (west) to watch, see the product of wind from the north, with a flicker of fire, including a big cloud, surrounded by glorious. Them from the fire seems to bring honor to be issued the overlaid with gold. show from one of four live to the image. ")

[Flight attitude --

A common UFO flying posture, and hanging Wensibudong Tingzaikongzhong not Heights from the ground or the air, but we did not see any way to ensure that hover in the sky any mechanical role in manifestations. Obviously, whether such as UFO will not use ordinary aircraft aerodynamics with the kind of buoyancy or to the flight. It seems, the UFO is not like helicopters, as with the propellers to hover. UFO flight hours and no smoke-free air regiment, thus precluding its use ordinary jet engine jet may be the driving force. Almost every UFO researchers will create the impression that: UFO gravitational have to offset some mechanical devices. Is this really?

[Flying saucer fever first appeared --

Flying saucer fever first appeared in January 1878, a Texas farmers J. Martin is in the air - a circular object. United States 150 newspapers published this news, such objects known as the "flying saucer." June 1947, the United States Idaho entrepreneurs K.

[On the UFO controversy]

Since the late 1940s, the dramatic increase in UFO might have witnessed the incident, the scientific community has aroused controversy. UFO because reproduction is not a can, or at least not often things happened, no inspection standards in the world so far has not yet formed a view of absolute authority. Hold a negative attitude toward the scientists that many witnessed the report is not credible, UFO does not exist, only the illusion of natural phenomena or witness a distortion can be used astronomy, meteorology, biology, psychology, physics and other scientific knowledge to be clearly stated. They even learn to fly butterflies as pseudoscience. Certainly argue that the UFO is a real concept, as is increasingly being confirmed by the fact that, but many UFO experts said they are not sure UFO alien ship. They think that we should not believe that the existence and believe it UFO alien from the theoretical confusion, because from the hypothesis that the universe is in accordance with its flight performance, and electromagnetic properties and witnesses to explain the impression summarized inferred, correctly or not to be check. Also part of UFO experts support the "extraterrestrial said." Some scholars also pointed out that the flying saucer phenomenon known in many areas and inconsistent with the basic laws of science, in the interpretation of this phenomenon at the difficulties encountered by the theory is that it is still unable to modern scientists recognized by the main reason, but not so on easily deny the existence of this phenomenon.

Answer 3

UFO
Origin: 1953

It is no coincidence that the first reported sightings of unidentified flying objects came after the revelations of the secret military projects of World War II. America has always been a land of invention, from the cotton gin to the telephone, from the airplane to the Motel (1925). But wartime inventions raised the status of our technology from awe-inspiring to mythic. Working in total secrecy while spending billions of dollars building whole cities and manufacturing plants, the Manhattan Project succeeded in extracting the energy of the atom and building a doomsday weapon. What could not be accomplished by the American military working in secret? What else was being accomplished?

This was the background for sightings of peculiar objects in the skies, beginning in June 1947, in the Southwestern desert area which had so many secret military installations. The objects could be some new super-secret aircraft developed by the U.S. military. Or could they have been developed by some other technologically advanced beings, perhaps from beyond the Earth or the solar system? After all, we now knew that the technology to permit space travel was possible. And these elusive objects traveled far faster and maneuvered far more adroitly than even a jet airplane.

There were many skeptics, however, who considered the objects pie in the sky--or more exactly "flying saucers" (1947), since excited observers had described the objects as saucer-shaped. The name flying saucers caught on, making serious research difficult. As a 1953 book Flying Saucers Have Landed complained, "ever since the cliché 'flying saucer' was coined, the greatest and most exciting mystery of our age has been automatically reduced to the level of a music hall joke."

The believers preferred the solemn government designation unidentified flying object, first used in 1950. But that was a little weighty for everyday use, so in 1953 the acronym UFO was coined to replace it. It has dignified the pursuit of the elusive objects ever since. Those who study them have been known at least since 1959 as ufologists, and their field of study has been ufology. But most people still couldn't find the alien spaceship in the tail of the Hale-Bopp comet of 1997, and the saucers--oops, UFOs--still haven't landed on the White House lawn.
