Laurel Army Air Field
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), founded as the Geological Survey, is an government agency, agency of the United States Department of the Interior, U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from List of NASA missions, U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas O-46
The Douglas O-46 is 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. It entered service in the late 1930s, and saw action in WW2. It became obsolescent later in the war as an observation craft, but was used for liaison, training, and ASW patrols. One airframe has survived as a museum piece into the present day. 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 |
Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-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, 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 manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevation
The elevation of a geographic location (geography), ''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 equipotential surface, surface (see Geodetic datum#Vertical datum, 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 ''three-dimensional space, 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 (volcano), Chimborazo have, respectively, the largest elevation and the largest ECEF, geocentric distance. Aviation In aviation, the term ''elevation'' or ''aerodrome elevation'' is defined by the IC ... [...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), that is, square metres (), 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 ( 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 () 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, is ...

Acre
The acre ( ) is a Unit of measurement, unit of land area used in the Imperial units, British imperial and the United States customary units#Area, United States customary systems. It is traditionally defined as the area of one Chain (unit), chain by one furlong (66 by 660 Foot (unit), feet), which is exactly equal to 10 square chains, of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare. Based upon the International yard and pound, international yard and pound agreement of 1959, an acre may be declared as exactly 4,046.8564224 square metres. The acre is sometimes abbreviated ac, but is usually spelled out as the word "acre".National Institute of Standards and Technolog(n.d.) General Tables of Units of Measurement . Traditionally, in the Middle Ages, an acre was conceived of as the area of land that could be ploughed by one man using a team of eight oxen in one day. The acre is still a statutory measure in the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
