UFOs By Silviya Koleva
1. The Definition of UFO • any real or apparent flying object which cannot be identified by the observer • remains unidentified after investigation • in popular culture, UFO is often used to refer to any hypothetical alien spacecraft The term flying saucer is also sometimes used
2. A brief history of UFOs • Some reports of unusual aerial phenomena date back to ancient times • reports of UFO sightings started becoming more common after the first widely publicized U.S. sighting in 1947 • Many more sightings may, however, remain unreportedbecause of social stigma around UFOs
3. Shapes of UFOs Sphere shaped
Top 4 UFOs cases in 90’s • 1991 Russian Crash & Retrieval a large elongated UFO invades Russian airspace. • After evading Russian MIGs, the object crashes into the mountains near the China Border. • Several expeditions are carried out to find the mysterious craft.
1992, South Haven • an alien space craft crashed into a remote area of Southaven Park in Shirley just before Thanksgiving, 1992. • the incident happened just after 7:00 P.M. on the night of November 24, according to John Ford, chairman of the Long Island U.F.O. Network, who said that it has taken his group six months to do a thorough investigation.
1995-American West Airline 564 • A cigar-shaped object with a row of brightly flashing lights along its length was observed over the Texas panhandle by the crew of a westward bound America West B-757 airliner on May 25, 1995 • The case was thoroughly investigated by Walter N. Webb on behalf of the UFO Research Coalition, who interviewed the crew and air traffic controllers. Webb also obtained a copy of the Federal Aviation Administration (FAA) voice tapes of conversations between airplane and ground during the sighting.
1997-The Phoenix Lights • Like a scene from a Sci-Fi movie, a huge, circular object slowly moved over the city of Phoenix and surrounding areas. • Numerous photographs, and an abundance of video film make this one of the best documented cases in UFO history. Numerous eye witness accounts recount a large, slow moving triangular shaped UFO.
4. Crop Circles • throughout history humans witnessed circles and other geometric figures made in the soil by mysterious craft. • crop circles are a phenomenon that have been happening as long as crop fields have existed. • they appear in various crops of growing grain like wheat, barley and oilseed rape (canola) that are the most common in England. But they have also been reported in oats, flax, rye, peas, potatoes, sweet corn maize and even in rice paddy fields in Japan. • Crop circles formations have also been detected in places covered with wild grass and undergrowth
mostly they appear during the three main summer months • around 250 crop designs around the world appear each year on average and several thousand have been documented since records began • at the beginning of the 1980s, the circles were very simple • later the designs of them have become increasingly much more complex each year. It seems that the progress of time has also played an important role in the development of shapes of these master pieces • many of them which recently appeared are very complex. • Naturally, there are many theories trying to explain crop circles' existence. One of them is alien origin
