The record — long form
Mount Rainier is where the flying saucer was born. On June 24, 1947, private pilot Kenneth Arnold was circling his CallAir southwest of the mountain, looking for a crashed Marine C-46, when a flash startled him. The source: nine bright objects in an echelon formation five miles long, weaving between the Cascade peaks, flipping and banking 'like the tail of a Chinese kite.' He timed them from Rainier to Adams — 47 miles in 102 seconds, roughly 1,700 mph, twice anything that could fly.
Arnold described them to reporters at Pendleton as moving 'like a saucer would if you skipped it across the water' — the wire services wrote 'flying saucer,' and the modern UFO era started from a misquote. Arnold spent the rest of his life insisting on the precision of what he'd actually said and seen — the crescent shape, the weaving flight, the speeds he'd calculated as a mountain pilot who knew those peaks 'like his own living room.'
The sighting launched everything — the 1947 flap, the Air Force investigations, the entire vocabulary. The C-46 he was searching for was never found; the objects were never identified. The mountain keeps both — the lost transport somewhere on its southwest flank, and the sky corridor where nine things flew faster than sound before sound had been broken.
Mount Rainier is the archive's saucer file — the 1947 Kenneth Arnold sighting of nine objects weaving between the Cascade peaks at 1,700 mph, the report that coined 'flying saucer' and started the modern UFO era.

A sighting that named the phenomenon keeps its mountain — the file's suggestion being that Rainier's hold is the first report: the nine objects between Rainier and Adams that turned a lost-plane search into the start of the UFO era.

Mount Rainier ( ray-NEER), also known as Tahoma ( tə-HOH-mə), is a large, active stratovolcano in the Cascade Range of the Pacific Northwest in the United States.
