This document discusses unidentified flying objects (UFOs) and provides several examples of UFO sightings and encounters that have been reported. It first defines a UFO as any unexplained object seen in the sky. It then summarizes two famous cases from the 1940s-50s of UFO photographs taken in McMinnville, Oregon and the alleged UFO crash in Roswell, New Mexico in 1947. The document also lists over 600 UFO-related calls made to a government hotline from 2007-2009 and notes reports of encounters with aliens.

2. An unidentified flying object, or UFO, in its most
general definition, is any apparent anomaly in the
sky (or near or on the ground, but observed
hovering, landing, or departing into the sky) that is
not readily identifiable as any known object or
phenomenon by visual observation and/or use of
associated instrumentation such as radar. These
anomalies were referred to popularly as "flying
saucers" or "flying discs" during the late 1940s and
early 1950s.

3. McMinnville UFO photographs
McMinnville is known among UFO researchers for now-famous
photographs published on the front page of the June 9, 1950 , reportedly of
an unidentified flying object seen almost a month earlier, May 11. The
Oregonian published the photographs the next day, and within a month they
were published in LIFE magazine. The photographs were taken on a farm
near Sheridan, Oregon by a Mr. and Mrs. Paul Trent. Mrs. Trent was the first to
see the object—it resembled a classic "flying saucer"— her husband got a
camera from their farmhouse and took two photos before the "saucer" flew
away. A debate has raged for decades between UFO researchers, who claim
that the photos are genuine and are among the best ever taken of a UFO, and
UFO skeptics/debunkers, who claim that the photos are a hoax. Both sides in
the debate have hired photographic experts numerous times to do a
professional analysis of the photos, but so far neither side has offered
convincing evidence to prove their case. The Trent's background was also
thoroughly checked, and to date no evidence has surfaced implicating them in
a hoax. The whole sequence of events has led to a "UFO Festival" being held in
McMinnville each year.

4. UFO identity:
International UFO Museum
Roswell has benefited from interest in the alleged UFO incident of
1947. It was the report of an object that crashed in the general
vicinity in June or July 1947, allegedly an extraterrestrial
spacecraft and its alien occupants. Since the late 1970s the incident
has been the subject of intense controversy and of conspiracy
theories as to the true nature of the object that crashed. The United
States Armed Forces maintains that what was recovered was debris
from an experimental high-altitude helium weather and surveillance
balloon belonging to a classified program named "Mogul" however,
many UFO proponents maintain that an alien craft was found and its
occupants were captured, and that the military then engaged in a
cover-up.

reported to Government's UFO hotline
from 2007 -2009.
•Archives show one man 'made weapon
to shoot down alien spaceships‘.
•These files reveal bizarre reports of
encounters with extraterrestrials,
including a man who claimed he lived
with an alien

16. CROP CIRCLE SHOWN IN SCARY MOVIE 2
Crop circles are crop formations. They are believed to be caused by UFOs
landing and roaming around in the fields. But many people also can easily
create hoaxes by using a long piece of rope and a plank to create publicity for
their farms, to appear on TV, for simple pranks, etc. making crop circles
destroys a lot of crop.
Twenty-six countries reported approximately 10,000 crop circles in the last
third of the 20th century; 90% of those were located in southern England.
Many of the formations appearing in that area are positioned near ancient
monuments, such as Stonehenge. According to one study, nearly half of all
circles found in the UK in 2003 were located within a 15 km (9.3 miles) radius
of Amesbury. Archeological remains can cause crop marks in the fields in the
shapes of circles and squares, but they do not appear overnight, and they are
always in the same places every year.
The scientific consensus is that most or all crop circles are man-made, with a
few possible exceptions due to meteorological or other natural phenomena.
