Unidentified flying object (commonly abbreviated as UFO or U.F.O.) is the popular term for any apparent aerial phenomenon whose cause cannot be easily or immediately identified by the observer. The United States Air Force, which coined the term in 1952, initially defined UFOs as those objects that remain unidentified after scrutiny by expert investigators, though today the term UFO is colloquially used to refer to any unidentifiable sighting regardless of whether it has been investigated. UFO reports increased precipitously after the first widely publicized U.S. sighting, reported by private pilot Kenneth Arnold in June 1947, that gave rise to the popular terms "flying saucer" and "flying disc." The term UFO is popularly taken as a synonym for alien spacecraft and generally most discussions of UFOs revolve around this presumption. UFO enthusiasts and devotees have created organizations, religious cults have adopted extraterrestrial themes, and in general the UFO concept has evolved into a prominent mythos in modern culture. Some investigators now prefer to use the broader term unidentified aerial phenomenon (or UAP), to avoid the confusion and speculative associations that have become attached to UFO. Another widely known acronym for UFO in Spanish, Portuguese, French, and Italian is OVNI (Objeto Volador No Identificado, Objeto Voador Não Identificado, Objet volant non identifié or Oggetto Volante Non Identificato).

Studies have established that the majority of UFOs are observations of some real but conventional object—most commonly aircraft, balloons, or astronomical objects such as meteors or bright planets—that have been misidentified by the observer as anomalies, while a small percentage of reported UFOs are hoaxes. Between 5% to 20% of anomalous sightings can be classified as unidentified in the strictest sense (see below for some studies).

The possibility that all UFO sightings are misidentifications of known natural phenomena inspired some debate in the scientific community about whether scientific investigation was warranted given the paucity of available empirical data. Very little peer-reviewed literature has been published in which scientists have proposed, studied or supported non-prosaic explanations for UFOs. Nevertheless, UFOs as a cultural phenomenon continues to be the subject of serious academic research and amateur investigators continue to advocate that UFOs represent real and unexplained events, whether or not they are associated with alien encounters.

What are the best documentaries on UFOs?
Q. What are some newer documentaries on UFOs? Ones with good evidence and details about government cover ups. None of the old movies that only have rednecks telling stories of sightings.

A. Look, the nearest possible habitable planets are so far from Earth that it would take a highly advanced technology to be able to come here. Such a highly advanced technology cannot possibly be "covered up" by any human government. I mean, really, how stupid would they have to be? And if they're that stupid, they aren't coming here, because they aren't able to come here, because they aren't technologically advanced enough to come here. When beings from other worlds do come here, then trust me: we'll all know it.

What would cause someone to be obsessed with UFOs?
Q. I know someone who's totally obsessed with UFOs and worships aliens. He's claimed to have encounters. What does it mean? I don't know how to react because I can't relate. I just smile.

A. They probably saw something they couldn't explain and are obsessed with finding out all they can about it. It's good to be well informed, but obsessions can sometimes divert the course of one's life.

Why do one quarter of the american adult population believe that UFOs are real?
Q. A survey showed that 1/4 of the whole american adult population believes UFOs are real. What's the reason this amount would be any bigger than those that beleive in santa clause and the easter bunny? Can somebody explain this mystery?(I want logical reasons, not reasons like "Because they're americans").

A. From having sat in a statistics class, I can say one thing about "surveys": You can easily manipulate those numbers in favor of whatever you are trying to prove/disprove. One-quarter of the adult population is a lot of folks. I find that survey a bit "suspect". But I think that most believe in UFO's because of how it makes for good news and box office profits. I mean when you think about it, a lot isn't heard about UFO's prior to the last century's space programs. From the time we had the potential to put men into space, there are those who realized that they could capitalize on this by stimulating the imagination. Now, the "what if?" has evolved into "it is".
