This Day in the History of Hoaxes: June 24
June 24, 1947: The Kenneth Arnold UFO Sighting
On this day in 1947, civilian pilot Kenneth Arnold reported seeing nine unidentified objects flying at supersonic speed past Mount Rainier. Newspaper accounts referred to what he saw as "flying saucers," which popularized this term. There's no indication that Arnold was lying about what he saw. Skeptics suggest that he might actually have been seeing birds or some kind of mirage. So his report itself isn't a hoax. But his report is widely credited with ushering in the modern era of UFO sightings, which has been a rich source of hoaxes. [wikipedia
