UFOs

America's fascination with flying saucers began in Washington state on June 24, 1947. Businessman and pilot Kenneth Arnold was flying his small plane from Chehalis to Yakima when he spotted what appeared to be a formation of nine strange aircraft traveling near Mt. Rainier. Arnold calculated they were flying at supersonic speeds of at least 1,200 miles an hour, something military aircraft of the day were incapable of doing.
