Thomasville Army Airfield
Thomasville Regional Airport is a city-owned, public-use airport located six nautical miles (7 mi, 11 km) northeast of the central business district of Thomasville, a city in Thomas County, Georgia, United States. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a ''general aviation'' facility. The airport does not have scheduled commercial airline service. History During World War II, Thomasville Army Airfield was a United States Army Air Forces Third Air Force training base for reconnaissance and later fighter pilots. In 1941, civic leaders applied to the Civil Aeronautics Administration to build a modern airport. A site was selected 8.5 miles ENE of the city. After the City and the County purchased 903 acres, the CAA awarded a $316,000 contract for the construction of two runways, fences, lighting, and a hangar. By the time the contract had been completed in September 1942, the City and County ha ... [...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 ...

Civil Aeronautics Administration (United States)
The Air Commerce Act of 1926 created an Aeronautic Branch of the United States Department of Commerce. Its functions included testing and licensing of pilots, certification of aircraft and investigation of accidents. In 1934, the Aeronautics Branch was renamed the Bureau of Air Commerce, to reflect the growing importance of commercial flying. It was subsequently divided into two authorities: the Civil Aeronautics Administration (CAA), concerned with air traffic control, and the Civil Aeronautics Board (CAB), concerned with safety regulations and accident investigation. Under the Federal Aviation Act of 1958, the CAA's powers were transferred to a new independent body, the Federal Aviation Administration (FAA). In the same year, the National Aeronautics and Space Administration (NASA) was created after the Soviet Union’s launch of the first artificial satellite. The accident investigation powers of the CAB were transferred to the new National Transportation Safety Board in 1967, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean Sea Level
There are several kinds of mean in mathematics Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics ..., especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value (magnitude (mathematics), magnitude and sign (mathematics), sign) of a given data set. For a data set, the ''arithmetic mean'', also known as "arithmetic average", is a measure of central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the data set were based on a series of observations obtained by sampling (statistics), sampling from a statistical population, the arithmetic mean is th ...

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 ...

P-51 Mustang
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October. The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the RAF as a tactical-reconnaissance aircraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-40 Warhawk
The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. It was the third most-produced American fighter of World War II, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built,Murphy and McNiece 2009, p. 83. all at Curtiss-Wright Corporation's main production facilities in Buffalo, New York. P-40 Warhawk was the name the United States Army Air Corps gave the plane, and after June 1941, the USAAF adopted the name for all models, making it the official name in the U.S. for all P-40s. The British Commonwealth and Soviet air forces used the name Tomahawk for models eq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

P-39 Airacobra
The Bell P-39 Airacobra is a fighter produced by Bell Aircraft for the United States Army Air Forces during World War II. It was one of the principal American fighters in service when the United States entered combat. The P-39 was used by the Soviet Air Force, and enabled individual Soviet pilots to collect the highest number of kills attributed to any U.S. fighter type flown by any air force in any conflict. Other major users of the type included the Free French, the Royal Air Force, and the Italian Co-Belligerent Air Force.Gunston 1980, p. 22. It had an unusual layout, with the engine installed in the center fuselage, behind the pilot, and driving a tractor propeller in the nose with a long shaft. It was also the first fighter fitted with a tricycle undercarriage.Angelucci and Matricardi 1978, p. 25. Although its mid-engine placement was innovative, the P-39 design was handicapped by the absence of an efficient turbo-supercharger, preventing it from performing high-altitud ...

Fort Myers Army Airfield
Page Field Army Airfield is an inactive United States Army Air Forces base, approximately 4 miles south of Fort Myers, Florida. It was active during World War II as a Third Air Force training airfield. It was closed on 30 September 1945, two years prior to the establishment of the United States Air Force as an independent service. Today, the facility is Page Field, a civilian general aviation reliever airport. Prior to the construction of Southwest Florida International Airport in the 1980s, it also served as a commercial service airport for the Fort Myers / Lee County area. History In 1924, the city of Fort Myers, Florida, purchased 670 acres of land south of the city with the intention of developing it into a municipal golf course. However, that plan was halted when a Florida "Land Bust" stopped development. In 1927, it became a civil airport named "Palmetto Field", for the large amount of palmetto brush growing in and around the airport. National Airlines commenced ...
