Kenneth Arnold Unidentified Flying Object Sighting
The Kenneth Arnold UFO sighting occurred on June 24, 1947, when private pilot Kenneth Arnold claimed that he saw a string of nine, shiny unidentified flying objects flying past Mount Rainier at speeds that Arnold estimated at a minimum of 1,200 miles an hour (1,932 km/hr). This was the first post-World War II 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. Sighting On June 24, 1947, Arnold was flying from Chehalis, Washington, to Yakima, Washington, in a CallAir A-2 on a business trip. He made a brief detour after learning of a $5,000 reward (equivalent to $ today) for the discovery of a U.S. Marine Corps C-46 transport airplane that had crashed near M ...

Dzus Fastener
The Dzus fastener, also known as a turnlock fastener or quick-action panel fastener, is a type of proprietary quarter-turn spiral cam lock fastener often used to secure skin panels on aircraft and other high-performance vehicles. It is named after its inventor William Dzus (). History The fastener was invented and patented by an American engineer of Ukrainian descent William Dzus in the early 1930s. Operation The cowling (10) and fuselage (11) can be quickly fastened together by bringing the cowling (10) to the fuselage (11), placing the shank (13) of the button (12) into the hole in the fuselage (25). The button (12) is turned by a screwdriver in its slot (21) to a position in which the slots (16) will hold the spring (22). As button (12) turns, the walls of its spiral slots (16) act as cams, and pull the intermediate section of the spring (22) from its relaxed position up into the slot's holes (18) past the slot's projections (17). The projection (17) in the slots (16) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richland, Washington
Richland () is a city in Benton County, Washington, United States. It is located in southeastern Washington at the confluence of the Yakima and the Columbia Rivers. As of the 2020 census, the city's population was 60,560. Along with the nearby cities of Pasco and Kennewick, Richland is one of the Tri-Cities, and is home to the Hanford nuclear site.

From this village, the Wanapum, Yakama and Walla Walla Indians harvested the salmon runs entering the Yakima River. Captain William Clark of the Lewis and Clark Expedition visited the mouth of the Yakima River on October 17, 1805. Formative years In 1904–1905, W.R.

Flash Gordon
Flash Gordon is the protagonist of a space adventure comic strip created and originally drawn by Alex Raymond. First published January 7, 1934, the strip was inspired by, and created to compete with, the already established ''Buck Rogers'' adventure strip. Creation The ''Buck Rogers'' comic strip had been commercially very successful, spawning novelizations and children's toys, and King Features Syndicate decided to create its own science fiction comic strip to compete with it. At first, King Features tried to purchase the rights to the ''John Carter of Mars'' stories by Edgar Rice Burroughs. However, the syndicate was unable to reach an agreement with Burroughs. King Features then turned to Alex Raymond, one of their staff artists, to create the story. One source for Flash Gordon was the Philip Wylie novel ''When Worlds Collide'' (1933). The themes of an approaching planet threatening the Earth, and an athletic hero, his girlfriend, and a scientist traveling to the new planet ...

Sound Barrier
The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible. The term ''sound barrier'' is still sometimes used today to refer to aircraft approaching Supersonic speed, supersonic flight in this high drag regime. Flying faster than sound produces a sonic boom. In dry air at 20 °C (68 °F), the speed of sound is 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s). The term came into use during World War II when pilots of high-speed fighter aircraft experienced the effects of compressibility, a number of adverse aerodynamic effects that deterred further acceleration, seemingly impeding flight at speeds close to the speed of sound. These difficulties represented a bar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Adams (Washington)
Mount Adams, known by some Native American tribes as Pahto or Klickitat, is a potentially active stratovolcano in the Cascade Range.
