UFOs are the unidentified flying objects. In popular culture, the term UFO–or unidentified flying object–refers to a suspected alien spacecraft, although its definition encompasses any unexplained aerial phenomena. since ancient times reports of UFO sightings have been reported at various times across the world thus raising questions about life on other planets and whether aliens or extraterrestrials have visited our land or not.They have become a major field of interest among people for a long time. the first known UFO sighting occurred in 1947 when pilot Kenneth Arnold spotted 9 disk shaped objects near Mt. Ranier , Washington. Mr. Arnold described that these objects moved like a rock skipping over water. Therefore the name “flying saucers” were coined. Around this time several other sightings were reported almost similar to the sightings reported by Kenneth Arnold. these sightings were around 853 in number in between June and July of 1947.Later these sightings were compiled by ted bloecher in 1967 publication.The sightings were collected from newspaper articles and a few were collected from Project Bluebook
In India two UFOs were sighted in different ages. In 1951 at a morning of 15 march at 10:20 a.m. , 25 members of a flying club saw in the sky one cigar-shaped object which was long, about one hundred foot. The UFO made a large loop and then vanished from sight. later in 1954 On 15 September in the afternoon a flying saucer was seen by about 800 people in three villages (Kadori, Borsa and Mangalda) in the manbhum district in Bihar.Mr Ijapada Chatterjee, manager of a mica mine, told the times of India that the UFO was about 12 feet in diameter and fry in color. The object descend to an altitude of about 500 feet, hovered for a few minutes and then soared upwards at an incredible speed, causing a tremendous gust of wind. In the year 2000, On 8 April at 11,55 p.m. a crowd of people in New Delhi the Indira Gandhi International airport saw a luminous yellow-orange cigar-shaped object. The UFO hovered over the air cargo terminal, wobbled and then disappeared.
Thus we can conclude that UFO sightings are common in this world and these sightings continues and several events keep on being added in the long list of sightings but the authority of their existence cannot be claimed . The real existence of these UFOs cannot be proved until we get concrete evidence to support claims. thus they are still unidentified and unexplained.
