3. Introduction
A term originally coined by the
military, an unidentified flying
object (usually abbreviated to UFO
or U.F.O.) is an unusual apparent in
the sky that is not readily identifiable
to the observer as any known object.
When UFO comes to earth, it is said
that alien are visiting the earth. Many
explanations are given by different
personalities and philosophers. But it
is still a mystery that who are these
UFOs and where did they come
from.

4. Specific Cases
 The Sacramento Bee and the San Francisco Call
reported the first sighting of the flap on November 18,
1896. Witnesses reported a light moving slowly over
Sacramento on the evening of November 17 at an
estimated 1,000 foot elevation. Some witnesses said
they could see a dark shape behind the light.
 The November 19, 1896 edition of the Stockton,
California Daily Mail featured one of the earliest
accounts of an alleged alien craft sighting. Colonel H. G.
Shaw claimed that while driving his buggy through the
countryside near Stockton he came across what
appeared to be a landed spacecraft.

5.  In one account from Texas, three men
reported an encounter with an airship and
with "five peculiarly dressed men" who
reported that they were descendant from
the lost tribes of Israel.
 An account by Alexander Hamilton of Leroy, supposedly
occurred about April 19, 1897, and was published in the
Yates Center Farmer’s Advocate of April 23. Hamilton, his
son, and a tenant witnessed an airship hovering over his
cattle pen.
 In one account from Texas, three men reported an
encounter with an airship and with "five peculiarly dressed
men" who reported that they were descendant from the
lost tribes o Israel; they had learned English from the 1553
north pole expedition led by Hugh Willoughby.

6. Studies
 Studies have established that the majority of UFO
observations are misidentified conventional objects
or natural phenomenon— most commonly aircraft,
balloons, noctilucent clouds, nacreous clouds, or
astronomical objects such as meteors or bright
planets with a small percentage even being hoaxes.
After excluding incorrect reports, however, it is
acknowledged that between 5% and 20% of reported
sightings remain unexplained, and as such can be
classified as unidentified in the strictest sense. .
Many reports have been made by trained observers
such as pilots, police, and the military; some involve
radar traces, so not all reports are visual.

7.  The void left by the lack of
institutional scientific study has given
rise to independent researchers and
groups, most notably MUFON
(Mutual UFO Network) and CUFOS
(Center for UFO Studies).The term
"Ufology" is used to describe the
collective efforts of those who study
reports and associated evidence of
unidentified flying objects. According
to MUFON, as of 2011 the number of
UFO reports to their worldwide
offices has increased by 67% from the
previous 3 years, which now average
around 500 reported sightings per
month. UFOs have become a relevant
theme in modern culture, and the
social phenomena have been the
subject of academic research in
sociology and psychology.

8. EXPLANATIONS
Hoaxes or misidentification
During the 1896-1897 wave, there were many attempts
to explain the airship sightings, including suggestion
of hoaxes, pranks, publicity stunts and hallucinations.
One man suggested the airships were swarms of
lightning beetles misidentified by observers.
Observers believed tat many airship tales were due to
“Enterprising reporters perpetrating journalistic
hoaxes.” However observers notes that these
accounts “are easy to identify because of their
tongue-in-cheek tone, and accent on the sensational.”

9. Human airships
Some argued that the airship reports were genuine
accounts. Steerable airships had been publicly
flown in the US since the Aereon in 1863, and
numerous inventors were working on airship and
aircraft designs (the idea that a secretive inventor
might have developed a viable craft with advanced
capabilities was the focus of Jules Verne's 1886
novel Robur the Conqueror). In fact, two French
army officers and engineers, Arthur Krebs and
Charles Renard, had successfully flown in an
electric-powered airship called the La France as
early as 1885, making no fewer than seven
successful flights in the craft over an eleven month
period.

10. Claims of extraterrestrial origin
Early citations of the extraterrestrial hypothesis, all
from 1897, include the Washington Times, which
speculated that the airships were "a reconnoitering
party from Mars"; and the Saint Louis Post-Dispatch,
which suggested of the airships, "these may be
visitors from Mars, fearful, at the last, of invading the
planet they have been seeking." (Jacobs, 29) In 1909,
a letter printed in the Otago Daily Times (New
Zealand) suggested that the mystery airship sightings
then being reported in that country were due to
Martian"atomic-powered spaceships." (Clark 2000,
123)

11. Investigations
 UFOs have been subject to investigations over
the years that vary widely in scope and scientific
rigor. Governments or independent academics in
the United States, Canada, the United Kingdom,
Japan, Peru, France, Belgium, Sweden, Brazil,
Chile, Uruguay, Mexico, Spain, and the Soviet
Union are known to have investigated UFO
reports at various times. These official reports
refer to the UFO of military term, and not, to the
supposed alien crafts. It dose not mean that the
above-mentioned governments recognized
supposed human contact with alien civilization.
