UFOs (unidentified aerial object) the article or abnormality that can not be explained in a accepted way, afterward a abundant analysis of accomplished and accomplished bodies in abstruse and amusing fields.

Terminology UFO and abutting appointment was developed by astronomer dr.J. Allen Hynek. Ufology is a pseudoscientific conduct that studies the UFO phenomenon.

The actualization of the term

It is believed that the avant-garde era of Ufology began with a abutting appointment pilot Kenneth Arnold, while aerial through the Cascade abundance ambit in Washington state, 24 lipnja 1947. year. He flew a baby aeroplane adapted into a appropriate chase and accomplishment in the mountains, analytic for a burst bottomward carriage aircraft C-46, who abolished in January. Climbed about 14 hours aerial from Chehalis to Yakima, affective in the administration of Mount Rainer at a acme of 3 to 3.5 km. Approaching the abundance ambit was afraid by several ablaze flashes of light. When it looked better, he saw a accumulation of nine altar in flight. Arnold was their flight up and bottomward like a angle that declared bouncing on the surface. He opened the window to more good abstraction the aberrant altar and estimated their acceleration at about 2200 km / h abbreviation any accessible exaggeration. The adventure took abode several months afore Chuck Yeager bankrupt the complete barrier alpha aircraft Bell X-1 and to bisected that speed. Arnold is additionally estimated that the accumulation starts at about 40 km abroad from his plane, a accumulation of aircraft itself ran 9 km. The media accept upgraded the already absurd news and add the appellation aerial saucer.

Precisely because the appellation aerial saucer, the government and the army began to appearance interest, and the media accept amorphous likes-dislikes accord with UFOs, which continued all the way to the present day.

Seriousness of the UFO botheration best accept contributed to an official analysis activity conducted by the U.S. Air Force back 1948. until 1969. The codenamed “sign (saucer) / Grudge / Blue Book”.

Hypothesis

The best-known hypotheses that attack to explain the antecedent of the UFO abnormality is absolutely ETH hypothesis. ETH (ekstraterestrična) antecedent is formulated aural the aggressive domain, admitting the stereotypes that such a conception fabricated by the lay observer.

ETH antecedent has clearly launched the cessation that a aggressive lath SIGN in 1948. The certificate formed the “Estimate of the Situation” (situation assessment), which concludes that the best antecedent that can explain the UFO phenomenon, it is an “alien hypothesis”. But Air Force Chief, General Hoyt S. Vandenberg alone the

abstracts of the board, ordered the abstracts destroyed, a lath was disbanded and replaced with a fresh accumulation “GRUDGE”. To date, there are no preserved copies of this document, but alone actual advertence to the same, on the base of which I begin out about its existence.

Because of the ample media and accurate agitation during the 1950s and 1960s, the U.S. Air Force offered the authorization of the University of Colorado to end this media circus. Professor Edward Condon has agreed to accomplish an “independent review” of abstracts calm in the projects “SIGN / GRUDGE / Blue Book”.But in the end and I Condonov Lath had to accord with arguable outbursts. Lath back the alpha followed factions and disconnected opinions. Once in a leaked centralized announcement that was hinted at Condonovu subjectivity, the agents is accursed and replaced by fresh members. 1969th year, the lath has completed the “final band-aid ufološkog issues” and assured that added abstraction of the UFO abnormality in any account can not accord to science. On the advocacy of the board, the U.S. Air Force has abeyant added abstraction of UFOs, which lasted 21 years.
