Most commonly reported shapes in UFO sightings gathered by the National UFO Reporting Center Online Database (NUFORC)[1]

This is a list of notable reported sightings of unidentified flying objects (UFOs) and related claims of close encounters or abductions. UFOs are generally considered to include any perceived aerial phenomenon that cannot be immediately identified or explained. Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained.[2][3][4] UFOs have been referred to using a range terms including the more specific "flying saucer" and the more general "unidentified anomalous phenomena" (UAP). The term "UAP" is sometimes used to avoid cultural associations with UFO conspiracy theories.[5][6][7]

Although often viewed as abnormal, UFO sightings are reported frequently.[8][9] During the United States' initial 1947 wave, over 800 sightings were reported in the news.[10] The British Ministry of Defence receives 100s of reports each year.[11] In Brazil, pilots alone report dozens of annual sightings.[12][13] A small portion of reported sightings have lasting cultural significance,[14] interpreted through the cultural and technological expectations of the time.[15]

We all saw, in a direction from north to south, something big and shiny reflecting the sun, like a huge oval moving at great speed.
