“On June 24, 1947, Kenneth Arnold, a businessman from Boise, Idaho, was flying a small plane near Mount Rainier when, according to Associated Press reports, he spotted a chain of nine “saucer-like” objects above and east of the mountain. Brilliant in the sun, these objects darted toward Mount Adams at “an incredible speed” that he estimated to be at least 1,200 miles per hour. Arnold’s story of saucer-shaped objects initiated a UFO craze that has not abated. Analyses by meteorologists and other scientists suggest that Mr. Arnold did not spot a visitor from another world, but rather a mountain wave cloud, a frequent visitor to the mountainous Pacific Northwest.” Pacific NorthwestMeteorologyUnidentified Flying ObjectsMount RainierUfology Book:The Weather of the Pacific Northwest Source: The Weather of the Pacific Northwest
