Hoover Field
Hoover Field was an early airport serving the city of Washington, D.C. It was constructed as a private airfield in 1925, but opened to public commercial use on July 16, 1926. It was located in Arlington, Virginia, near the intersection of the Highway Bridge and the Mount Vernon Memorial Parkway, where The Pentagon and its northern parking lots now stand.Peck, 2005, p. 8. Considered one of the most hazardous airfields in the United States, Hoover Field suffered from short and unpaved runways, numerous life-threatening obstructions around the field, poor visibility (due to a burning garbage dump to its northwest), and poor drainage. It was purchased by the owner of nearby Washington Airport in early 1929, causing a brief merger of the two fields, but was sold to a new owner just 12 months later. It nearly went bankrupt in 1933, and was sold at auction and merged with Washington Airport to become Washington-Hoover Airport on August 2, 1933. Washington-Hoover Airport closed in Ju ...

Washington Airport
Washington Airport was the second major airport to serve the city of Washington, D.C., in the United States. Located in Arlington, Virginia, near the intersection of the Highway Bridge and the Mount Vernon Parkway (where The Pentagon's south parking lots, Metrobus bus bays, and a portion of Interstate-395 now exist).Peck, 2005, p. 8. The first airport to serve the city was Hoover Field, a private airfield constructed in 1925. Washington Airport, a private airport triple the size of Hoover Field, was built literally across the road in late 1927. The airfield suffered from short and unpaved runways, numerous life-threatening obstructions around the field, poor visibility (due to a burning garbage dump adjacent to each field), and poor drainage. Washington Airport nearly went bankrupt in 1933, and it was auctioned off to a new owner. The new owner also owned Hoover Field, and merged the two into a single airfield, Washington-Hoover Airport. Washington-Hoover Airport closed in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highway Bridge (Potomac River)
The 14th Street bridges refers to the three bridges near each other that cross the Potomac River, connecting Arlington, Virginia and Washington, D.C. Sometimes the two nearby rail bridges are included as part of the 14th Street bridge complex. A major gateway for automotive, bicycle and rail traffic, the bridge complex is named for 14th Street ( U.S. Route 1), which feeds automotive traffic into it on the D.C. end. The complex contains three four-lane automobile bridges — including, from west to east, one southbound, one bi-directional, and one northbound — that carry Interstate 395 (I-395) and U.S. Route 1 (US 1) traffic, as well as a bicycle and pedestrian lane on the southbound bridge. In addition, the complex contains two rail bridges, one of which carries the Yellow Line of the Washington Metro; the other of which, the only mainline rail crossing of the Potomac River to Virginia, carries a CSX Transportation rail line. The five bridges, from we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfill
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

Amusement Park
An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects. Amusement parks evolved from European fairs, pleasure gardens, and large picnic areas, which were created for people's recreation. World's fairs and other types of international expositions also influenced the emergence of the amusement park industry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windsock
A windsock (also called a wind cone) is a conical textile tube that resembles a giant sock. It can be used as a basic indicator of wind speed and direction, or as decoration. They are typically used at airports to show the direction and strength of the wind to pilots, and at chemical plants where there is risk of gaseous leakage. They are also sometimes located alongside highways at windy locations. At many airports, windsocks are externally or internally lit at night. Function Wind direction is the direction in which the windsock is pointing. (Wind directions are conventionally specified as the compass point from which the wind originates; so a windsock pointing due north indicates a southerly wind). Wind speed is indicated by the windsock's angle relative to the mounting pole; in low winds it droops; in high winds it flies horizontally. Alternating stripes of high visibility orange and white were initially used to help to estimate wind speed, with each stripe adding 3 knots ...

Herbert Hoover
Herbert Clark Hoover (August 10, 1874 – October 20, 1964) was an American politician who served as the 31st president of the United States from 1929 to 1933 and a member of the Republican Party, holding office during the onset of the Great Depression in the United States. A self-made man who became rich as a mining engineer, Hoover led the Commission for Relief in Belgium, served as the director of the U.S. Food Administration, and served as the U.S. Secretary of Commerce. Hoover was born to a Quaker family in West Branch, Iowa, but he grew up in Oregon. He was one of the first graduates of the new Stanford University in 1895. He took a position with a London-based mining company working in Australia and China. He rapidly became a wealthy mining engineer. In 1914 at the outbreak of World War I, he organized and headed the Commission for Relief in Belgium, an international relief organization that provided food to occupied Belgium. When the U.S. entered the war in 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Secretary Of Commerce
The United States secretary of commerce (SecCom) is the head of the United States Department of Commerce. The secretary serves as the principal advisor to the president of the United States on all matters relating to commerce. The secretary reports directly to the president and is a statutory member of Cabinet of the United States. The secretary is appointed by the president, with the advice and consent of the United States Senate. The secretary of commerce is concerned with promoting American businesses and industries; the department states its mission to be "to foster, promote, and develop the foreign and domestic commerce".

United States Declaration Of Independence
The United States Declaration of Independence, formally The unanimous Declaration of the thirteen States of America, is the pronouncement and founding document adopted by the Second Continental Congress meeting at Pennsylvania State House (later renamed Independence Hall) in Philadelphia, Pennsylvania, on July 4, 1776. Enacted during the American Revolution, the Declaration explains why the Thirteen Colonies at war with the Kingdom of Great Britain regarded themselves as thirteen independent sovereign states, no longer subject to British colonial rule. With the Declaration, these new states took a collective first step in forming the United States of America and, de facto, formalized the American Revolutionary War, which had been ongoing since April 1775. The Declaration of Independence was signed by 56 of America's Founding Fathers, congressional representatives from New Hampshire, Massachusetts Bay, Rhode Island and Providence Plantations, Connecticut, New York, New Jer ...

Kingman Island
Kingman Island (also known as Burnham Barrier) and Heritage Island are islands in Northeast and Southeast Washington, D.C., in the Anacostia River. Both islands are man-made, built from material dredged from the Anacostia River and completed in 1916.''Department of the Interior and Related Agencies Appropriations for 1994...,'' 1994, p. 79.Turner, ''Justice on Earth: Earthjustice and the People It Has Served,'' 2002, p. 54.Forgey, "The Anacostia, Stream of Consciousness," ''Washington Post,'' March 28, 1987.Barker, "Clouds Gathering Over Children's Island," ''Washington Post,'' August 9, 1991. Kingman Island is bordered on the east by the Anacostia River, and on the west by Kingman Lake. Heritage Island is surrounded by Kingman Lake. Both islands were federally owned property managed by the National Park Service until 1995. They are currently owned by the District of Columbia government, and managed by Living Classrooms National Capital Region. Kingman Island is bisected by Benn ...

Kingman Lake
Kingman Lake is a artificial lake located in the Anacostia River in Washington, D.C., in the United States. The lake was created in 1920 when the United States Army Corps of Engineers used material dredged from the Anacostia River to create Kingman Island.''Department of the Interior and Related Agencies Appropriations for 1994...,'' 1994, p. 79. The Corps of Engineers largely blocked the flow of the Anacostia River to the west of Kingman Island, creating the lake (although some water is permitted to enter the lake to prevent it from completely evaporating and to refresh its waters). Kingman Lake is currently managed by the National Park Service. Early history of the Lake Prior to the arrival of European settlers in the 18th century, the Anacostia River was a fast-flowing and relatively silt-free river with very few mudflats or marshes. White settlers cleared much of the surrounding forest for farmland, however, and extensive soil erosion led to a heavy load of silt and effluent ...

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 ...
