Even though reports of strange flying objects have been made throughout history, no one really tried to make a concerted study of them until the second half of the 20th Century. It was around the advent of World War II that the number of UFO sightings really began to multiply around the world. Beginning with the "ghost" flyers in the1930's through the foo fighters of the 1940's sightings of unidentifiable aerial objects were becoming codified through the 1950's.

With the post-war "Cold War" heating up between the United States and the Soviet Union, this increase in sightings of unknown and technologically superior aircraft presented a unique problem for those responsible for national defense. It became necessary for them to make a special effort to analyze these reports and try to figure out whether they were advanced enemy craft or something else. Regrettably, whatever was discovered, the military efforts at ufology did not pass on their findings to the general population. They hid their findings under the guise of national security and officially stated there was no problem, this despite an increasing number of events and continued invasion of the airspace around military bases and nuclear facilities.

Ufology for the public was left to the civilians to figure out. With the urging of the military, the media and scientific community was encouraged to ridicule the entire field of UFO studies. With a lack of backing from the mainstream establishment, ufology quickly ran into trouble as a real science. Academia mostly abandoned the subject to amateurs. There was no scientific consensus or peer review systems set in place. Anyone could call themselves a ufologist without any organizational body to take them to task to prove their credentials. Even accepted and mainstream scientists like Jacques Vallee and J. Allen Hynek encountered ridicule of their work even though Hynek originally became involved in ufology through the military studies.

At best, ufology has been relegated to the status of a "pseudoscience." While ufologist protest this labeling, they still rarely maintain or sometimes even adhere to the simplest of scientific methodology in their research. They often make bold statements with no real supporting evidence. Many theories are not only implausible but impossible to quantify or qualify by any known scientific process. There is no single moderating and overseeing community to establish control guidelines or methodology to satisfy the necessary demands of scientific standards of research or peer review.

There are a few major difficulties with the UFO phenomena, which make a scientific approach more difficult. The observed events are neither predictable, convenient, nor replicable. This makes scientific experimentation very near impossible to formulate. Skeptics argue that, with no physical evidence, ufology cannot equate itself with science at all.

Until ufology can find ways to codify and compartmentalize these problems, it will never be taken as true science. Until a form of standardization and peer review is adapted, the skeptics, unbelievers, and hoaxers will continue to flood any discussion of the UFO phenomena with scurrilous, derogatory, and deceptive information without any great fear of being discovered or disavowed.

Basically the ufology is the state of self denial. For majority of the purposes and intents it appears to be a dead issue. The reason is that it is practiced by only a few people but it is infiltrated by many, who fail to realize the importance of this field as a scientific endeavor. Hampering the studying of this phenomenon by applying illogical or unexplainable skeptics or debunking through ignorance or hidden agenda or maybe expounding it with data which is not factual cheapens the quest for knowledge.

Ufology as a scientific area of reach and study, fails at many other levels as well. This branch fails to evolve by the normal processes as other sciences has achieved. In 60 years, this branch has failed to formulate a specific language for understanding, like found in many other branches of science. Like for example in medical profession, all the practitioners speak common language which is accepted universally.

A second front on which this branch fails is that it is not using its history as a base. Almost all the other recognized branches of science use history as a plan to investigate their past, present and future events.

There are many deficiencies in the field of Ufology, some are innocent but most of them are man made. Some of these fallacies are discussed below.

First and foremost is the belief by the majority that the Ufology covers all areas of the paranormal. Well it does not. Crop circles, rods, Bigfoot, crystal grazing, spook lights etc are not part of the branch which is known as Ufology. Any attempt to associate all these with Ufology is a very big error.

Second, the science have taken a very hard look at the data relating to the UFO issue and found that it lacks scientific merit or explanations. This is however, false. There has never been an applied, long run, unbiased and funded research effort regarding the collected data and documentation by any area or branch of sciences regarding this UFO issue. Erroneously this phenomenon is declared null and void.

Third is that, the earth is being visited by aliens. There is no evidence or data to prove this, this only remains a hypothesis. However there is enough hard data to prove that UFO’s do exist. The fact is that nobody knows yet from where these UFO’s come and where they go, neither any one has any clue regarding purpose of their appearance.

The last is the allegedly covering up of famous UFO incidents by the military or the government. These tend to make such events more mysterious and suspicious. These government bodies had failed to give any possible logical explanations on various famous UFO incidents like, the Roswell incident, the Kecksburg incident etc.

Alien abductions, flying saucers and extraterrestrials. Are they just fantasy or realty? Either of the ways it is a realm that many people take seriously. Now there is a dedicated semi scientific area of research for these unidentified flying objects known as Ufology. Nevertheless, it is an exciting filed. The main research started only after the Second World War when there was a sudden spurt in the sightings of UFO’s. Since then, many scientists and astronomers believe that these so called sightings are just related to whether patterns and astronomical events like meteor events, hot air balloons or military planes. But there are many people in this world who believe that these sightings have got something to do with extra terrestrials.

Nowadays you will find many stories and legends related to UFO sightings and aliens. Besides the witnesses there are many fixed evidences about the UFO’s which were filmed or photographed.

It was this UFO theory that gave birth to many other theories like aliens landing from other planets and flying saucers as vehicles for falling angels etc.

The first major video footage of UFO’s was made in 1994 when during the war the allied pilots encountered what they call “enemy weapons” or “foo fighters”. One of the most notable and investigated incident of UFO sighting is the famous Roswell incident which happened in the year 1947. The people living in New Mexico City saw a disc like object flying in the sky. This was a usual UFO sighting however the army further mystified this by saying that an UFO has crashed in Roswell and debris and bodies or aliens were discovered, however almost immediately the army issued another contradictory statement claiming that they had made a mistake in identifying the object and it was a hot air balloon and not an UFO. Now who will believe that a well equipped and sophisticated army like this, will mistake a hot air balloon as an UFO. Many say that U.S army is hiding some really very important facts, other say that they are experiment something big, the truth however nobodies know.

In each of the case both sides, the skeptics and the believers have evidences supporting their own claims. Those who believe in aliens and UFO’s cite some facts that cannot be logically explained. And those who are skeptical offer their explanation with their supporting evidences. Now it is up to you to decide that which side is right and which is wrong.
