15 Most Convincing Alien Sightings in the US

On June 24, 1947, pilot Kenneth Arnold saw nine unusual, boomerang-shaped objects flying rapidly near Mount Rainier. He calculated their speed by observing how quickly they moved between mountain peaks, and the media soon began calling these objects “flying saucers” because of his description. This sighting sparked many similar reports nationwide that summer. The U.S. Air Force collected statements about the incident and filed it away as one of the earliest UFO cases.
