The History of UFOs

I. comprehension and Appreciation

1. What does UFO refer to? How much do you know about UFOs?

In popular culture, the term UFO–or unidentified flying object–refers to a suspected alien spacecraft, although its definition encompasses any unexplained aerial phenomena. UFO sightings have been reported throughout recorded history and in various parts of the world, raising questions about life on other planets and whether extraterrestrials have visited Earth. They became a major subject of interest–and the inspiration behind numerous films and books–following the development of rocketry after World War II.

2. Why was the first UFO sighting called flying saucers?

The first well-known UFO sighting occurred in 1947, when businessman Kenneth Arnold claimed to see a group of nine high-speed objects near Mount Rainier in Washington while flying his small plane. Arnold estimated the speed of the crescent-shaped objects as several thousand miles per hour and said they moved ―like saucers skipping on water.‖ In the newspaper report that followed, it was mistakenly stated that the objects were saucer-shaped, hence the term flying saucer.

3. What project did the U.S. Air Force launch to begin its investigation of sightings of unidentified aerial phenomena? To name the projects in sequence.

Sightings of unidentified aerial phenomena increased, and in 1948 the U.S. Air Force began an investigation of these reports called Project Sign. Then there were its successors as follows: Project Grudge, Project Blue Book.

4. After three days’ meeting and interview and review of films and photographs of UFOs, what conclusions did the the Robertson Panel get?

Their conclusions were that (1) 90 percent of the sightings could be easily attributed to astronomical and meteorologic phenomena (e.g., bright planets and stars, meteors, auroras, ion clouds) or to such earthly objects as aircraft, balloons, birds, and searchlights, (2) there was no obvious security threat, and (3) there was no evidence to support the ETH.

5. How come did the second committee come into being? And did it share anything with the Robertson Panel? And what conclusion did it come to?

A second committee was set up in 1966 at the request of the Air Force to review the most interesting material gathered by Project Blue Book. Like the Robertson Panel, the committee concluded that there was no evidence of anything other than commonplace phenomena in the reports and that UFOs did not warrant further investigation.

6. What did J. Allen Hynek do despite the failure of the ETH to make headway with the expert committees?

J. Allen Hynek, an astronomer at Northwestern University in Evanston, Ill., who had been involved with projects Sign, Grudge, and Blue Book, concluded that a small fraction of the most-reliable UFO reports gave definite indications for the presence of extraterrestrial visitors. Hynek founded the Center for UFO Studies (CUFOS), which continues to investigate the phenomenon.

7. Where were the only other official and fairly complete records of UFO sightings kept aside from Project Blue Book?

Aside from Project Blue Book, the only other official and fairly complete records of UFO sightings were kept in Canada, where they were transferred in 1968 from the Canadian Department of National Defense to the Canadian National Research Council. The Canadian records comprised about 750 sightings.

8. What attitude did the Soviet Union hold towards sightings of UFOs? And what about China?

In the Soviet Union, sightings of UFOs were often prompted by tests of secret military rockets. In order to obscure the true nature of the tests, the government sometimes encouraged the public's belief that these rockets …… 此处隐藏：6392字，全部文档内容请下载后查看。喜欢就下载吧 ……
