Witnessing a formation of strange craft flying in the skies over Mt. Rainier Washington and ushers in the modern age of Flying Saucers on this day in June 24 1947. While flying near Mt. Rainier in Washington State, Arnold claimed to have seen nine unusual objects flying in the skies. Arnold also claimed to have seen UFOs on several subsequent occasions.
Arnold originally described the UFOs shape as "flat like a pie pan", "half-moon shaped, oval in front and convex in the rear", "something like a pie plate that was cut in half with a sort of a convex triangle in the rear", or simply "saucer-like" or "like a big flat disk" (see quotes), and also described their erratic motion being "like a fish flipping in the sun" or a saucer skipped across water. From these, the press quickly coined the new terms "flying saucer" and "flying disc" to describe such UFOs, many of which were reported within days after Arnold's sighting. Later Arnold would add that one of the UFOs actually resembled a crescent or flying wing.
