An unidentified flying object, or UFO, is any real or apparent
flying object which cannot be identified by the observer and which 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.
Reports of unusual aerial phenomena date back to ancient times, but reports
of UFO sightings started becoming more common after the first widely publicized
U.S. sighting in 1947. Many tens of thousands of UFO reports have since been
made worldwide. Many more sightings may, however, remain unreported due to fear
of public ridicule because of the social stigma surrounding the subject of UFOs,
and because most nations lack any officially sanctioned authority to receive and
evaluate UFO reports.
Once a UFO is identified as a known object (for example an aircraft or weather
balloon), it ceases to be classified as a UFO and is reclassified as an identified object.
First modern reports
Before the terms “flying saucer” and “UFO” were coined, there were a number
of reports of strange, unidentified aerial phenomena. These reports date from
the mid-nineteenth to early twentieth century. They include:
-
In July, 1868, The investigators of this phenomenon define the first modern
documented sighting as having happened in Copiapo city, Chile.[6]
-
On January 25, 1878, The Denison Daily News wrote that local farmer
John Martin had reported seeing a large, dark, circular flying object resembling
a balloon flying “at wonderful speed.”[7]
- On February 28, 1904, there was a sighting by three crew
members on the USS Supply 300
miles west of San
Francisco, reported by Lt. Frank Schofield, later to become
Commander-in-Chief
of the Pacific Fleet. Schofield wrote of
three bright red egg-shaped and circular objects flying in echelon formation
that approached beneath the cloud layer, then changed course and “soared” above
the clouds, departing directly away from the earth after 2 to 3 minutes. The
largest had an apparent size of about six suns.[8][9]
-
An unusual phenomenon on November 17, 1882 was observed by astronomer Edward Walter Maunder of the Greenwich Royal Observatory and
some other European astronomers.
Numerous sighting reports were written up in Nature and other scientific journals.
Maunder in The Observatory reported “a
strange celestial visitor” that
was "disc-shaped," "torpedo-shaped," "spindle-shaped," or "just like a Zeppelin" dirigible (as he described it in 1916). It was much
brighter than the concurrent auroral displays, had well-defined edges and was
opaque in the center, whitish or greenish-white, about 30 degrees long and 3
degrees wide, and moved steadily across the northern sky in less than 2 minutes
from east to west. Maunder said it was very different in characteristics from a
meteor fireball or any aurora he had ever seen. Nonetheless,
Maunder (and some other astronomers) thought it was probably related to the huge
auroral magnetic sunspot storm
occurring at the same time; Maunder called it an "auroral beam." [10]
-
The so-called Fátima incident
or “The
Miracle of the Sun,” witnessed by tens of thousands in Fátima,
Portugal on October 13, 1917, is believed by some researchers to
actually be a UFO event.
-
On 5 August 1926, while traveling in the Humboldt Mountains of Tibet's Kokonor
region, Nicholas
Roerich reported that members of his expedition saw--high in the sky, above
an eagle they had been watching--"something big and shiny reflecting sun, like a
huge oval moving at great speed" (from his travel diary Altai-Himalaya,
published 1929). While Roerich does not say what he thought the object might
have been, surrounding passages discuss Theosophical accounts of ancient civilizations and
their technology.[11]
-
On February 25, 1942, the U.S. Army detected unidentified
aircraft both visually and on radar over the Los Angeles, California region. The craft stayed aloft despite
taking at least 20 minutes worth of flak
from ground batteries. The origins of the aircraft were never identified. The
incident later became known as the Battle of Los Angeles, or the West coast air
raid.
-
In 1946, there were over 2000 reports of unidentified aircraft in the Scandinavian nations, along with
isolated reports from France, Portugal, Italy and Greece,
then referred to as “Russian hail,” and later as “ghost rockets,” because it was thought that these
mysterious objects were Russian tests of
captured German V1 or V2 rockets. This was subsequently shown not to be the case,
and the phenomenon remains unexplained. Over 200 were tracked on radar and
deemed to be “real physical objects” by the Swedish military. A significant
fraction of the remainder were thought to be misidentification of natural
phenomena, such as meteors.
Modern UFO era
The post World War II UFO phase in the United States began with a reported
sighting by American businessman Kenneth Arnold on June 24, 1947 while
flying his private plane near Mount Rainier, Washington. He reported seeing nine brilliantly
bright objects flying across the face of Rainier towards nearby Mount
Adams at “an incredible speed”, which he calculated as at least 1200 miles
per hour by timing their travel between Rainier and Adams. His sighting
subsequently received significant media and public attention. Arnold would later
say they “flew like a saucer would if you skipped it across the water” and also
said they were “flat like a pie pan”, “shaped like saucers,” and “half-moon
shaped, oval in front and convex in the rear. ...they looked like a big flat
disk.” (One, however, he would describe later as being almost crescent-shaped.)
Arnold’s reported descriptions caught the media’s and the public’s fancy and
gave rise to the terms flying saucer and flying disk.
Arnold’s sighting was followed in the next few weeks by several thousand
other reported sightings, mostly in the U.S., but in other countries as well.
Perhaps the most significant of these was a United Airlines crew sighting of nine more
disc-like objects over Idaho on the
evening of July 4. This sighting was
even more widely reported than Arnold’s and lent considerable credence to
Arnold’s report. For the next few days most American newspapers were filled with
front-page stories of the new “flying saucers” or “flying discs.” Starting with
official debunkery that began the night of July 8 with the Roswell UFO incident, reports rapidly
tapered off, ending the first big U.S. UFO wave.
Starting July 9, Army Air Force intelligence, in
cooperation with the FBI, secretly began a
formal investigation into the best sightings, which included Arnold’s and the
United crew’s. The FBI was told that intelligence was using “all of its
scientists” to determine whether or not “such a phenomenon could, in fact,
occur.” Furthermore, the research was “being conducted with the thought that the
flying objects might be a celestial phenomenon,” or that “they might be a
foreign body mechanically devised and controlled.” (Maccabee, 5) Three weeks
later they concluded that, “This ‘flying saucer’ situation is not all imaginary
or seeing too much in some natural phenomenon. Something is really flying
around.”[12] A further review by the intelligence and
technical divisions of the Air Materiel Command at Wright Field
reached the same conclusion, that “the phenomenon is something real and not
visionary or fictitious,” that there were objects in the shape of a disc,
metallic in appearance, and as big as man-made aircraft. They were characterized
by “extreme rates of climb [and] maneuverability,” general lack of noise,
absence of trail, occasional formation flying, and “evasive” behavior “when
sighted or contacted by friendly aircraft and radar,” suggesting either manual,
automatic, or remote control. It was thus recommended in late September 1947
that an official Air Force investigation be set up to investigate the
phenomenon.[13] This led to the creation of the Air Force’s Project Sign at the end of
1947, which became Project
Grudge at the end of 1948, and then Project Blue Book in 1952. Blue Book closed
down in 1970, ending the official Air Force UFO investigations.
Use of “UFO” instead of “flying saucer” was first suggested in 1952 by Capt.
Edward J.
Ruppelt, the first director of Project Blue Book, who felt that “flying
saucer” did not reflect the diversity of the sightings. Ruppelt suggested that
“UFO” should be pronounced as a word — “you-foe”. However it is generally
pronounced by forming each letter: “U.F.O.” His term was quickly adopted by the
Air Force, which also briefly used “UFOB” circa 1954. (See next paragraph.)
Ruppelt recounted his experiences with Project Blue Book in his memoir, The
Report on Unidentified Flying Objects (1956), also the first book to use the
term.[14]
Air Force
Regulation 200-2, issued in 1954, defined an Unidentified
Flying Object (UFOB) as “any airborne object which by performance,
aerodynamic characteristics, or unusual features, does not conform to any
presently known aircraft or missile type, or which cannot be positively
identified as a familiar object.” The regulation also said UFOBs were to be
investigated as a “possible threat to the security of the United States” and “to
determine technical aspects involved.” Furthermore, Air Force personnel were
directed not to discuss unexplained cases with the press.[15]
UFOs in popular culture
Beginning in the 1950s, UFO-related spiritual sects, sometimes referred to as contactee cults, began to appear.Most often the
members of these sects rallied around a central individual, who claimed to
either have made personal contact with space-beings, or claimed to be in telepathic contact with them.
Prominent among such individuals was George Adamski, who claimed to have met a tall,
blond-haired Venusian named “Orthon,” who
came to warn us about the dangers of nuclear proliferation. Adamski was widely
dismissed, but an Adamski
Foundation still exists, publishing and selling Adamski’s writings. At least
two of these sects developed a substantial number of adherents, most notably The
Aetherius
Society, founded by British mystic George King in 1956, and the Unarius
Foundation, established by “Ernest L.” and Ruth Norman in 1954. A
standard theme of the alleged messages from outer-space beings to these cults
was a warning about the dangers of nuclear proliferation. More recent groups
organized around an extraterrestrial theme include Ummo, Heaven’s Gate, The Raëlian Movement, and the Ashtar
Galactic Command. Many of the early UFO sects, as well as later ones, share
a tendency to incorporate ideas from both Christianity and various eastern religions,
“hybridizing” these with ideas pertaining to extraterrestrials and their
benevolent concern with the people of Earth.
The notion of contactee cults gained a new twist during the 1980s, primarily
in the USA, with the
publication of books by Whitley Strieber (beginning with Communion) and Jacques Vallee
(Passport to Magonia). Strieber, a horror writer, felt that aliens were harassing him and were
responsible for “missing
time” during which he was subjected to strange experiments by “grey aliens”. This newer, darker model can be
seen in the subsequent wave of “alien abduction” literature, and in the background mythos of The X
Files and many other TV series.
However, even in the alien abduction literature, motives of the aliens run
the gamut from hostile to benevolent. For example, researcher David Jacobs
believes we are undergoing a form of stealth invasion through genetic
assimilation. The theme of genetic manipulation (though not necessarily an
invasion) is also strongly reflected in the writings of Budd Hopkins. The late Harvard psychiatrist John Mack (1929-2004)
believed that the aliens’ ethical bearing was to take a role as “tough love” gurus trying to impart wisdom. James Harder says abductees predominantly report positive interactions
with aliens, most of whom have benevolent intentions and express concern about
human survival.
An interesting 1970s-era development was a renewal and broadening of ideas
associating UFOs with supernatural or preternatural subjects such as occultism, cryptozoology, and parapsychology. Some 1950s contactee cultists
had incorporated various religious and occult ideas into their beliefs about
UFOs, but in the 1970s this was repeated on a considerably larger scale. Many
participants in the New Age movement
came to believe in alien contact, both through mediumistic channeling and through literal, physical contact. A
prominent spokesperson for
this trend was actress Shirley MacLaine,
especially in her book and miniseries, Out On a Limb.
The 1970s saw the publication of many New Age books in which ideas about UFOs
and extraterrestrials figured prominently.
Another key development in 1970s UFO folklore came with the publication of Erich von
Däniken’s book Chariots of the Gods. The book argued
that aliens have been visiting Earth for
thousands of years, which he used to explain UFO-like images from various archaeological sources as
well as unsolved mysteries. Such ideas were not exactly new. For example,
earlier in his career, astronomer Carl Sagan in Intelligent Life in the
Universe (1966) had similarly argued that aliens could have been visiting
the Earth sporadically for millions of years. “Ancient astronauts” proposals inspired
numerous imitators, sequels, and fictional adaptations, including one book (Barry Downing's
The Bible and Flying Saucers) which interprets miraculous aerial
phenomena in the Bible as records of alien
contact. Many of these interpretations posit that aliens have been guiding human evolution, an
idea taken up earlier by the novel and film 2001: A Space Odyssey.
UFOs constitute a widespread international cultural phenomenon of the last half-century.
Folklorist Thomas E. Bullard
writes, “UFOs have invaded modern consciousness in overwhelming force, and
endless streams of books, magazine articles, tabloid covers, movies, TV shows, cartoons, advertisements, greeting cards, toys, T-shirts,
even alien-head salt and pepper shakers, attest to the popularity of this
phenomenon.” Gallup polls
rank UFOs near the top of lists for subjects of widespread recognition. In 1973,
a survey found that 95 percent of the public reported having heard of UFOs,
whereas only 92 percent had heard of US President Gerald Ford in a 1977 poll
taken just nine months after he left the White House. (Bullard, 141) A 1996 Gallup poll reported that 71
percent of the United
States population believed that the government was covering up
information regarding UFOs. A 2002 Roper poll for the Sci Fi channel found similar
results, but with more people believing UFOs were extraterrestrial craft. In
that latest poll, 56 percent thought UFOs were real craft and 48 percent that
aliens had visited the Earth. Again, about 70 percent felt the government was not sharing everything it knew about UFOs or extraterrestrial life.
Physical evidence
Besides visual sightings, cases sometimes have alleged associated direct or
indirect physical evidence, including many cases studied by the military and
various government agencies of different countries. Indirect physical evidence
would be data obtained from afar, such as radar contact and photographs. More
direct physical evidence involves physical interactions with the environment at
close range—Hynek's "close encounter" or Vallee's "Type-I" cases—which include
"landing traces," electromagnetic interference, and
physiological/biological effects.
A list of various physical evidence cases from government and private studies
includes:
-
Radarcontact and tracking, sometimes
from multiple sites. These are often considered among the best cases since they
usually involve trained military personnel and control tower operators,
simultaneous visual sightings, and aircraft intercepts. One such recent example
were the mass sightings of large, silent, low-flying black triangles in 1989 and 1990 over Belgium, tracked by multiple NATO radar and jet interceptors, and investigated by Belgium's military (included photographic evidence).[18] Another famous case from
1986 was the JAL 1628
case over Alaska investigated by the FAA.[19]
-
Photograpic evidence, including still photos, movie film, and video,
including some in the infrared
spectrum (rare).
-
Recorded visual spectrograms (extremely rare) — (see Spectrometer)
-
Recorded gravimetric and
magnetic disturbances (extremely
rare)
-
Landing physical trace evidence, including ground impressions, burned and/or
desiccated soil, burned and broken foliage, magnetic anomalies, increased
radiation levels, and metallic traces. See, e.g. Height 611
UFO Incident or the 1964 Lonnie Zamora's Socorro, New Mexico encounter, considered one of the most
inexplicable of the USAF Project Blue Book cases). A well-known
example from December 1980 was the USAF Rendlesham Forest Incident in
England. Another less than 2 weeks later, in January 1981, occurred in
Trans-en-Provence and was investigated by GEPAN, then France's official government
UFO-investigation agency.[20] Project Blue Book head Edward J. Ruppelt
described a classic 1952 CE2 case involving a patch of charred grass roots.[21] Catalogs
of several thousand such cases have been compiled, particularly by researcher
Ted Phillips.[22][23]
-
Physiological effects on people and animals including temporary paralysis,
skin burns and rashes, corneal burns,
and symptoms resembling radiation poisoning, such as the Cash-Landrum
incident in 1980. One such case dates back to 1886, a Venezuelan incident
reported in Scientific American magazine.[24]
-
So-called animal/cattle mutilation cases, that some feel are
also part of the UFO phenomenon. Such cases can and have been analyzed using forensic science
techniques.
-
Biological effects on plants such as increased or decreased growth,
germination effects on seeds, and blown-out stem nodes (usually associated with
physical trace cases or crop
circles)
-
Electromagnetic interference(EM)
effects, including stalled cars, power black-outs, radio/TV interference,
magnetic compass deflections, and aircraft navigation, communication, and engine
disruption.[25] A list of over 30 such aircraft EM incidents was
compiled by NASA scientist Dr. Richard F.
Haines.[26] A famous 1976 military case over Tehran, recorded in CIA and DIA classified documents, resulted
in communication losses in multiple aircraft and weapons system failure in an F-4 jet interceptor as it was about to fire a
missile on one of the UFOs. This was also a radar/visual case. (Fawcett &
Greenwood, 81-89; Good, 318-322, 497-502)[27][28]
-
Remote radiation detection, some noted in FBI and CIA documents
occurring over government nuclear installations at Los Alamos National Laboratory
and Oak Ridge National Laboratory in
1950, also reported by Project Blue Book director Ed Ruppelt in his
book.[29]
-
Actual hard physical evidence cases, such as 1957, Ubatuba, Brazil, magnesium fragments analyzed by the Brazilian
government and in the Condon
Report and by others. The 1964 Socorro/Lonnie Zamora incident also left metal traces,
analyzed by NASA.
-
Misc: Recorded electromagnetic emissions, such as microwaves detected in the
well-known 1957 RB-47 surveillance aircraft case, which was also a visual and
radar case;[30] polarization rings observed around a UFO by a
scientist, explained by Dr. James Harder as intense magnetic fields from the
UFO causing the Faraday
effect.[31]
These various reported physical evidence cases have been studied by various
scientist and engineers, both privately and in official governmental studies
(such as Project
Blue Book, the Condon Committee, and the French GEPAN/SEPRA).
A comprehensive scientific review of physical evidence cases was carried out by
the 1998 Sturrock UFO panel.[32]
Attempts have been made to reverse engineer the possible physics behind UFOs through analysis of
both eyewitness reports and the physical evidence. Examples are former NASA and nuclear engineer James McCampbell in
his book Ufology online, NACA/NASA engineer Paul R. Hill in his book Unconventional Flying
Objects, and German rocketry pioneer Hermann Oberth. Among subjects tackled by
McCampbell, Hill, and Oberth was the question of how UFOs can fly at supersonic speeds without creating
a sonic boom. McCampbell's
proposed solution of a microwave plasma parting the air in front of
the craft is currently being researched by Dr. Leik Myrabo, Professor of Engineering Physics at
the Rensselaer Polytechnic
Institute as a possible advance in hypersonic flight.[33]1995

Explanations and opinions
Statistics compiled by U.S. Air Force studies from 1947-1970 found that the
strong preponderance of identified sightings were due to misidentifications,
with hoaxes and psychological aberrations accounting for only a few percent of
all cases.
Nevertheless, many cases remained unexplained. An Air Force study by Battelle
Memorial Institute scientists from 1952-1955 of 3200 USAF cases found 22% were unknowns, and with the best cases, 33% remained unsolved. Similarly about 30% of the UFO cases studied by the 1969 USAF Condon Committee were deemed unsolved when
reviewed by the American
Institute of Aeronautics and Astronautics (AIAA). The official French
government UFO scientific study (GEPAN/SEPRA) from 1976 to 2004 listed about 13%
of 5800 cases as very detailed yet still inexplicable (with 46% deemed to have
definite or probable explanations and 41% having inadequate information).[34]
Despite the remaining unexplained cases in the cited scientific studies
above, many skeptics still argue that the general opinion of the mainstream scientific
community is that all UFO sightings could ultimately be explained by prosaic
explanations such as misidentification of natural and man-made phenomena (either
known or still unknown), hoaxes, and psychological phenomena such as optical illusions
or dreaming/sleep paralysis (often
given as an explanation for purported alien abductions)
Other skeptical arguments against UFOs include:
-
Most evidence is ultimately derived from notoriously unreliable eyewitness
accounts and very little in the way of solid or other physical evidence has been reported.
-
Most UFO sightings are transitory events and there is usually no opportunity
for the repeat testing called for by the scientific method.
-
Occam's razorof
hypothesis testing, since it is considered less incredible for the explanations
to be the result of known scientifically verified phenomena rather than
resulting from novel mechanisms (e.g. the extraterrestrial hypothesis).
-
The market being biased in favour of books, TV specials, etc. which support
paranormal interpretations, leaving the public poorly informed regarding more
mundane explanations for UFOs as a possibly socio-cultural phenomenon only.[35]
Popular ideas for explaining UFOs
To account for hardcore unsolved cases, a number of explanations have been
proposed by both proponents and skeptics. Among proponents, some of the more
common explanations for UFOs are:
-
-
-
-
The hypothesis that they are time machines or vehicles built in a future time.
Similarly, skeptics usually propose the following explanations:
Other explanations:
-
"shiny-bodied insects"[36]
-
Usually a combination of explanations is cited to explain all cases, and even
proponents will sometimes invoke skeptical explanations, such as man-made
military aircraft, to possibly account for some unsolved cases.
