Kee Bird
The ''Kee Bird'' was a United States Army Air Forces Boeing B-29 Superfortress, serial ''45-21768'', of the 46th Reconnaissance Squadron, that became marooned after making an emergency landing in northwest Greenland during a secret Cold War spying mission on 21 February 1947. While the entire crew was safely evacuated after spending three days in the isolated Arctic tundra, the aircraft itself was left at the landing site. It lay there undisturbed until 1994, when a privately funded mission was launched to repair and return it. During the attempted recovery, a fire broke out, resulting in the destruction and loss of the airframe on the ground. Mission background In the early years of the Cold War, some of the most important strategic reconnaissance was carried out by Strategic Air Command units deployed to Ladd Army Airfield, near Fairbanks, Alaska Territory. One of the SAC's initial missions was to plan strategic aerial reconnaissance on a global scale. The first efforts were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Intelligence
Signals intelligence (SIGINT) is intelligence-gathering by interception of '' signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-17 Flying Fortress
The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Relatively fast and high-flying for a bomber of its era, the B-17 was used primarily in the European Theater of Operations, United States Army, European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the List of most-produced aircraft, third-most produced bomber of all time, behind the four-engined Consolidated B-24 Liberator and the multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. In a USAAC competition, Boeing, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, then introduced it into service in 1938. The B-17 evolved through numerous Boei ...

Point Barrow
Point Barrow or Nuvuk is a headland on the Arctic coast in the U.S. state of Alaska, northeast of Utqiaġvik (formerly Barrow). It is the northernmost point of all the territory of the United States, at , south of the North Pole. (The northernmost point on the North American mainland, Murchison Promontory in Canada, is farther north.) Point Barrow is an important geographical landmark, marking the limit between two marginal seas of the Arctic Ocean, the Chukchi Sea to the west and the Beaufort Sea to the east. It was named by English explorer Frederick William Beechey in 1826 for Sir John Barrow, a statesman and geographer of the British Admiralty. The water around it is normally ice-free for two or three months a year, but this was not the experience of the early explorers. Beechey could not reach it by ship and had to send a ship's boat ahead. In 1826 John Franklin tried to reach it from the east and was blocked by ice. In 1837 Thomas Simpson walked 50 miles wes ...

Alaska Standard Time
The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time ( UTC−09:00). During daylight saving time its time offset is eight hours ( UTC−08:00). The clock time in this zone is based on mean solar time at the 135th meridian west of the Greenwich Observatory. The zone includes nearly all of the U.S. state of Alaska and is one hour behind the Pacific Time Zone. *standard time: Alaska Standard Time (AKST) *daylight saving time: Alaska Daylight Time (AKDT) The western Aleutian Islands observe Hawaii–Aleutian Time, one hour behind the remainder of the state. The largest city in the Alaskan Time Zone is Anchorage, Alaska. The Anchorage Metropolitan Area is the largest metropolitan area in the zone. Effective from 2007, the local time changes from AKST to AKDT at 02:00 LST to 03:00 LDT on the second Sunday in March and returns at 02:00 LDT to 01:00 LST on the first Sunday in November.

Great Circle
In mathematics, a great circle or orthodrome is the circular intersection of a sphere and a plane passing through the sphere's center point. Any arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space. For any pair of distinct non- antipodal points on the sphere, there is a unique great circle passing through both. (Every great circle through any point also passes through its antipodal point, so there are infinitely many great circles through two antipodal points.) The shorter of the two great-circle arcs between two distinct points on the sphere is called the ''minor arc'', and is the shortest surface-path between them. Its arc length is the great-circle distance between the points (the intrinsic distance on a sphere), and is proportional to the measure of the central angle formed by the two points and the center of the sphere. A great circle is the largest circle that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
