Polar Route
A polar route is an aircraft route across the uninhabited polar ice cap regions. The term "polar route" was originally applied to great circle navigation routes between Europe and the west coast of North America in the 1950s. The Arctic Early years In August 1935, the Soviet aviator Sigizmund Levanevsky and his two crewmen attempted a transpolar flight from Moscow, Russian SFSR, Soviet Union to San Francisco, California. The flight was aborted because of technical issues before they reached the North Pole. In 1936, Levanevsky and navigator Victor Levchenko completed a more-than- multistage flight from Los Angeles to Moscow in a Vultee V-1A floatplane, thus proving the possibility of an air route between the United States and the Soviet Union via the Bering Strait. Another Soviet pilot Valery Chkalov and his crew were the first to fly non-stop from Europe to the American Pacific Coast. from Moscow to Vancouver, Washington, United States, via the North Pole on a Tupolev ANT-25 s ...

Flight Path
In the United States, airways or air routes are defined by the Federal Aviation Administration (FAA) in two ways: "VOR Federal airways and Low/Medium Frequency (L/MF) (Colored) Federal airways" These are designated routes which aeroplanes fly to aid in navigation and help with separation to avoid accidents. Airways are defined with segments within a specific altitude block, corridor width, and between fixed geographic coordinates for satellites navigation system, or between ground-based radio transmitter navigational aids (navaids; such as VORs or NDBs) or the intersection of specific radials of two navaids. United States History To guide airmail pilots on their delivery routes, the United States Postal Service constructed the first airways in the United States, the Contract Air Mail routes. These airways were between major cities and identified at night by a series of flashing lights and beacons which pilots flew over in sequence to get from one city to the next. I ...

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the North magnetic pole, Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipode (geography), antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though ...

Kangerlussuaq Airport
Kangerlussuaq Airport (, , formerly ''Søndre Strømfjord Lufthavn'' in Danish) is an airport in Kangerlussuaq, a settlement in the Qeqqata municipality in central-western Greenland. It was originally built as Sondrestrom Air Base (Bluie West-8) in 1941, but assumed its current civilian role in 1992. Alongside Nuuk Airport and Narsarsuaq Airport, it is one of only three civilian airports in Greenland large enough to handle large aircraft. It is still used for NATO and Danish Defence purposes. Kangerlussuaq Airport was previously the international hub for Air Greenland. Most traffic transitioned to Nuuk Airport in November 2024, coinciding with the opening of its new lengthened runway and terminal. History Foundation and early years The first airport was built here during the US occupation in 1941 under the name of Bluie West-8, later renamed Sondrestromfjord Air Base and Sondrestrom Air Base. The airport is located away from the coast and hence less prone to fog and win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Douglas DC-6B
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles. The DC-6 was known as the C-118 Liftmaster in United States Air Force service and as the R6D in United States Navy service before 1962, after which all U.S. Navy variants were also designated as the C-118. Design and development The United States Army Air Forces commissioned the DC-6 project as the XC-112 in 1944. The Army Air Forces wanted a lengthened, pressurized version of the DC-4-based C-54 Skymaster transport with more-powerful engines. By the time the prototype XC-112A flew on 15 February 1946, the war was over, the USAAF had rescinded its requirement, and the ai ...

Boeing B-29 Superfortress
The Boeing B-29 Superfortress is a retired 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 Boeing 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 and a half dollar cost of design and production (equivalent to $6769 billion in 400), fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
