Events

in 1947

Kenneth Arnold makes the first widely reported UFO sighting near Mount Rainier, Washington. The Kenneth Arnold UFO sighting was an incident on June 24, 1947, where private pilot Kenneth Arnold claimed he spotted a string of nine, shiny unidentified flying objects flying past Mount Rainier at then unheard of supersonic speeds that Arnold clocked at a minimum of 1,200 miles an hour. This was the first post-War sighting in the United States that garnered nationwide news coverage and is credited with being the first of the modern era of UFO sightings, including numerous reported sightings over the next two to three weeks. Arnold's description of the objects also led to the press quickly coining the terms flying saucer and flying disc as popular descriptive terms for UFOs. Based on subsequent analysis, skeptical investigator Philip J. Klass concluded that Arnold may have seen a fireball bolide breaking up as it traveled through the Earth's atmosphere.

Ambrose Bierce

Ambrose Gwinnett Bierce was an American editorialist, journalist, short story writer, fabulist, and satirist. Today, he is probably best-known for his short story "An Occurrence at Owl Creek Bridge" and his satirical lexicon The Devil's Dictionary. His vehemence as a critic, his motto "Nothing matters" and the sardonic view of human nature that informed his work all earned him the nickname "Bitter Bierce".
