NAS Alameda
Naval Air Station Alameda (NAS Alameda) was a United States Navy Naval Air Station mostly in Alameda, California, with a slight portion of it within San Francisco proper, on San Francisco Bay. NAS Alameda had two runways: 13–31 measuring and 07-25 measuring . Two helicopter pads and a control tower were also part of the facilities. History In 1927, wetlands at the west end of Alameda Island on the east shore of San Francisco Bay were filled to form an airport (Alameda Airport) with an east–west runway, three hangars, an administration building, and a yacht harbor. The airport site included the Alameda Terminal of the First transcontinental railroad (California Historical Landmark #440). By 1930, United States Army Air Corps operations referred to the site as Benton Field. Pan American World Airways used the yacht harbor as the California terminal for '' China Clipper'' trans-Pacific flights beginning in 1935. The ''China Clipper'' terminal is designated California Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alameda, California
Alameda ( ; ; Spanish for "Avenue (landscape), tree-lined path") is a city in Alameda County, California, United States, located in the East Bay (San Francisco Bay Area), East Bay region of the Bay Area. The city is built on an informal archipelago in San Francisco Bay, consisting of Alameda (island), Alameda Island, Bay Farm Island, Alameda, California, Bay Farm Island and Coast Guard Island, along with other smaller islands. As of the 2020 United States census, 2020 census, the city's population was 78,280. History Ohlone era Alameda originally occupied a peninsula connected to Oakland, California, Oakland. The area was low-lying and marshy, while higher ground was part of one of the largest coastal oak forests in the world. A local band of the Ohlone tribe inhabited the region for more than 3,000 years. They were present at the time of the arrival of the Spanish in the late 18th century. The Ohlone created numerous oyster shell mounds across the peninsula, some as large as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes ...

Carrier Air Wing
A carrier air wing (abbreviated CVW) is an operational naval aviation organization composed of several aircraft squadron (aviation), squadrons and detachments of various types of fixed-wing aircraft, fixed-wing and rotorcraft, rotary-wing aircraft. Organized, equipped and trained to conduct modern US Navy carrier air operations while embarked aboard aircraft carriers, the various squadrons in an air wing have different but complementary (and sometimes overlapping) missions, and provide most of the striking power and electronic warfare capabilities of a carrier battle group (CVBG). While the CVBG term is still used by other nations, the CVBG in US parlance is now known as a carrier strike group (CSG). Until 1963, Carrier Air Wings were known as Carrier Air Groups (CVGs). Carrier Air Wings are what the United States Air Force would call "composite" wings, and should not be confused with U.S. Navy List of United States Navy aircraft wings, ''Type'' Wings (such as Strike Fight ...

Naval Air Station
A Naval Air Station (NAS) is a military air base, and consists of a permanent land-based operations locations for the military aviation division of the relevant branch of a navy (Naval aviation). These bases are typically populated by squadrons, groups or wings, their various support commands, and other tenant commands. The term "Naval Air Station" is used by many countries' navies, such as the United States Navy, the Royal Australian Navy, the Royal Navy, and the Indian Navy. In the case of the U.S. Navy, similar facilities in the U.S. Marine Corps are known as Marine Corps Air Stations and facilities in the U.S. Coast Guard are known as Coast Guard Air Stations. Argentinean Navy The Argentine Naval Aviation operates four ''Base Aeronaval'' (BAN): from BAN Punta Indio (BAPI) in Buenos Aires Province through BAN Comandante Espora (BACE) and BAN Almirante Zar (BAAZ) in Patagonia to BAN Almirante Quijada (BARD) at Tierra del Fuego. Runways also serve domestic airlines a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Gate International Exposition
The Golden Gate International Exposition (GGIE) was a World's Fair held at Treasure Island in San Francisco, California, U.S. The exposition operated from February 18, 1939, through October 29, 1939, and from May 25, 1940, through September 29, 1940; it drew 17 million visitors to Treasure Island. Among other things, it celebrated the city's two newly built bridges: the San Francisco–Oakland Bay Bridge and the Golden Gate Bridge. History The idea to hold a World's Fair to commemorate the completion of the Bay Bridge and Golden Gate Bridge began with a letter to '' The San Francisco News'' in February 1933. Architects W.P. Day and George Kelham were assigned to consider the merits of potential sites around the city, including Golden Gate Park, China Basin, Candle Stick Point, and Lake Merced. By 1934, the choice of sites had been narrowed to the areas adjoining the two bridges: either "an island built up from shallow water" north of Yerba Buena Island (which would go on to be ...

Treasure Island (California)
Treasure Island is a man-made island in San Francisco Bay, and a neighborhood in the City and County of San Francisco. Built in 1936–37 for the 1939 Golden Gate International Exposition, the island was named by Clyde Milner Vandeburg, part of the Fair's public relations team. Its World's Fair site is a California Historical Landmark. Buildings there have been listed on the National Register of Historic Places, and the historical Naval Station Treasure Island, an auxiliary air facility (for airships, blimps, dirigibles, planes and seaplanes), are designated in the Geographic Names Information System. Treasure Island is connected to Yerba Buena Island, another (natural) auxiliary island of San Francisco, by a causeway, creating access to Interstate 80 in California, Interstate 80. Geography The San Francisco census tract that includes Treasure Island extends up and down San Francisco Bay and includes a small uninhabited tip of western Alameda (island), Alameda Island.

China Clipper
''China Clipper'' (NC14716) was the first of three Martin M-130 four-engine flying boats built for Pan American Airways and was used to inaugurate the first commercial transpacific airmail service from San Francisco to Manila on November 22, 1935. Built at a cost of $417,000 by the Glenn L. Martin Company in Baltimore, Maryland, it was delivered to Pan Am on October 9, 1935. It was one of the largest airplanes of its time. On November 22, 1935, it took off from Alameda, California on commission to deliver the first airmail cargo across the Pacific Ocean. Although its inaugural flight plan called for the ''China Clipper'' to fly over the San Francisco–Oakland Bay Bridge (still under construction at the time), upon take-off the pilot realized the plane would not clear the structure, and was forced to fly narrowly under instead. On November 29, the airplane reached its destination, Manila, after traveling via Honolulu, Midway Island, Wake Island, and Sumay, Guam, and delivered o ...

Pan American World Airways
Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. The first airline to fly worldwide, it pioneered innovations such as Wide-body aircraft, jumbo jets and computerized reservation systems, and introduced the Boeing 707, first American jetliner in 1958. Until its dissolution on December 4, 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. In the 1930s, under the le ...

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the United States Department of the Air Fo ...
