24 June 1947, Private pilot Kenneth Arnold was flying near Mount Rainier when he reported seeing a group of reflective craft moving at high speeds and flashing in the sun like mirrors. Bill Bequette of the East Oregonian, who first interviewed Arnold, summarized the sighting as, "nine saucer-like aircraft flying in formation." This introduced the term flying saucers, and Arnold's sighting sparked an explosion of UFO reports around the country.
