Kenneth Arnold made what is generally considered the first widely reported unidentified flying object sighting in the United States, after claiming to have seen nine unusual objects flying in tandem near Mount Rainier, Washington on June 24, 1947. This is his story, written with the help of Raymond Palmer, who was the editor of Amazing Stories and Fate Magazine.
