UFO means “unidentified flying object”, also called “UFO” or “flying saucer.” It is generally believed that the modern UFO era began on June 24, 1947, when a pilot named Kenneth A. Arnold in the United States was flying a CallAir A-2. Nine luminous bodies jumping up and down, like “flying saucers jumping on the water”, moving at two to three times the speed of sound. However, scientists at the time asserted that flying saucers did not exist because they could not exist. Later, a large number of sighting reports were mostly attributed to “mild weather allergy” and “group hypnotized.” Under the conditions of the Cold War, the US government’s attitude was also to conceal and arbitrarily explain, to downplay the impact caused by UFOs. But it still can’t stop a large number of UFO enthusiasts, both official and private. UFOs and aliens have always been unsolved mysteries that have made people quite interested.
Time flies, time flies, more than half a century has passed, and now more and more UFO sightings have been reported from all over the world. Take the United States as an example. According to statistics from the National UFO Reporting Center, they received a total of 7,213 UFO sighting reports in 2020, a 21% increase from 5,957 in 2019. Recently, UFO videos taken by the U.S. military have exploded, and the Pentagon has publicly confirmed that those videos are true. It may become increasingly difficult for the US government to conceal the existence of UFO.
