Laurel Army Airfield
Hesler-Noble Field is a public airport in Jones County, Mississippi. It is owned by Laurel Airport Authority and is three miles southwest of Laurel, Mississippi. The National Plan of Integrated Airport Systems for 2011–2015 called it a ''general aviation'' facility. It has no scheduled airline service. History Laurel Airport opened in April, 1940, having been built by the Works Project Administration. Alarmed by the fall of France in June 1940, Congress funded an increase from 29 to 54 combat groups in the United States Army Air Corps. The quickest way to get bases was to use existing civil airports. The Air Corps signed an agreement to lease Laurel Airport, but construction did not begin until mid 1942. Construction involved runways and airplane hangars, with three concrete runways, several taxiways and a large apron and a control tower. Several large hangars were built. Buildings were utilitarian and quickly assembled. Most base buildings, not meant for long-term use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth anniv ...

Douglas O-46
The Douglas O-46 was an observation aircraft used by the United States Army Air Corps and the Philippine Army Air Corps."Douglas Aircraft Builds the DC-1 and DC-2." ''U.S. Centennial of Flight Commission,'' 2003. Retrieved: 27 September 2007. Design and development The O-46A, the last of a long line of Douglas observation aircraft, was a victim of progress. It was designed to operate from established airfields behind fairly static battle lines as in . However, in 1939, a report was issued on the O-46A which stated that it was too slow and heavy to outrun and outmaneuver enemy fighter aircraft, too heavy to operate from small, w ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Elevation
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while ''altitude'' or ''geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and '' depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Air Technical Service Command
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

Jackson Army Air Base
Hawkins Field is a joint civil-military public airport in Jackson, Mississippi. It is owned by the City of Jackson and operated by the Jackson Municipal Airport Authority. The National Plan of Integrated Airport Systems for 2011–2015 called it a ''general aviation'' facility. History Aviation in Jackson began in 1928 with the purchase of 151 acres of pasture land in the City of Jackson known then as Davis Stock Farm, for $53,500. Davis Field, Jackson's first airport was dedicated November 9, 1928. Delta Air Lines made its first flight that year beginning in Dallas landing in Jackson and other cities en route to Atlanta. In 1936 the Works Progress Administration's (WPA), Civil Conservation Corps (CCC) invested $62,150 to improve the airport with a terminal building and paving of an apron. In 1941 the airfield was named Hawkins Field after A.F. Hawkins, a city commissioner with an interest in aviation. World War II In May 1941 the Dutch government-in-exile, following the ...

020 is the national dialling code for London in the United Kingdom. All subscriber numbers within the area code consist of eight digits and it has capacity for approaching 100 million telephone numbers. The code is used at 170 telephone exchanges in and around Greater London as part of the largest linked numbering scheme in the United Kingdom. In common with all other British area codes the initial '0' is a trunk prefix that is not required when dialling London from abroad. The 020 area code fully replaced older area codes for London on 22 April 2000, following multiple telephone number changes during the 1990s.020 could be used from 1 June 1999 and the previous 0171 and 0181 codes could no longer be used from 22 April 2000. As is the case for other codes in the UK, the 020 area code may also be used for services without any physical presence in the area, such as private networks or virtual numbering.
