America (airship)
The ''America'' was a non-rigid airship built by Mutin Godard in France in 1906 for the journalist Walter Wellman's attempt to reach the North Pole by air. Wellman first conceived of using a balloon to fly to the pole during a failed polar attempt by boat and sledge from Svalbard in 1894. He then visited Paris to review the state of balloon technology but left disappointed by the lack of acceptable steering and propulsion capability. A decade later while at the 1905 Portsmouth Peace Conference he learned of recent innovations in French dirigible design and believed a solution might be at hand for his Arctic aerial plan. After receiving the backing of newspaper publisher Victor F. Lawson, the Wellman '' Chicago Record-Herald'' Polar Expedition was announced, and Wellman traveled to Paris in search of a suitable design and manufacturer. In the meantime a public company was established to raise the $US 250,000 required for the expedition and airship (to which Lawson contributed ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Melvin Vaniman
Chester Melvin Vaniman (October 30, 1866 – July 2, 1912) was an American aviator and photographer who specialized in panoramic images. He shot images from gas balloons, ships masts, tall buildings and even a home-made pole. He scaled buildings, hung from self-made slings, and scaled dangerous heights to capture his unique images. Early life Born to a farming family in Virden, Illinois, Vaniman was the eldest of four sons and attended Valparaiso University in Indiana and Chicago. Career Photography Vaniman's photographic career began in Hawaii in 1901, and ended some time in 1904. He spent over a year photographing Australia and New Zealand on behalf of the Oceanic Steamship Company, creating promotional images for the company, many as panoramas and which popularised the format in Australia, which was taken up with enthusiasm by Robert Vere Scott among others. During this time the New Zealand Government also commissioned panoramas. Beginning in 1903, he spent ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Callsign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a Identifier, unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptography, cryptographically encryption, encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one Electrical telegraph, telegraph line linking all railroad stations, there needed to be a way to Address space, address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; Radio industry, radio companies initially assigned two-letter identifiers to coast radio station, coastal stations and marine radio, stations onboard ships at sea. ...

Spark Gap
A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the potential difference between the conductors exceeds the breakdown voltage of the gas within the gap, a spark forms, ionizing the gas and drastically reducing its electrical resistance. An electric current then flows until the path of ionized gas is broken or the current reduces below a minimum value called the "holding current". This usually happens when the voltage drops, but in some cases occurs when the heated gas rises, stretching out and then breaking the filament of ionized gas. Usually, the action of ionizing the gas is violent and disruptive, often leading to sound (ranging from a ''snap'' for a spark plug to thunder for a lightning discharge), light and heat. Spark gaps were used historically in early electrical equipment, such as spark gap radio transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth#Surface, Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8th paralle ...

Transatlantic Flight
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, Central America, or South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloons and other aircraft. Early aircraft engines did not have the reliability nor the power to lift the required fuel to make a transatlantic flight. There were difficulties navigating over the featureless expanse of water for thousands of miles, and the weather, especially in the North Atlantic, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commercial, military, diplomatic, and other purposes. History The idea of transatlantic flight came about with the advent of the hot air balloon. The balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough lift to use the winds that would later ...

Frederick Cook
Frederick Albert Cook (June 10, 1865 – August 5, 1940) was an American explorer, physician, and ethnographer who claimed to have reached the North Pole on April 21, 1908. That was nearly a year before Robert Peary, who similarly claimed to have reached the North Pole on April 6, 1909. Both men's accounts have been disputed ever since. His expedition was the first, and the only one with a United States national, to find a previously unknown, to people of European descent, North American Arctic island, Meighen Island. In December 1909, after reviewing Cook's limited records, a commission of the University of Copenhagen ruled his claim unproven. In 1911, Cook published a memoir of his expedition that continued his claim. His account of reaching the summit of Denali (Mount McKinley) in Alaska has also been discredited. Biography Cook was born in Hortonville, New York, in Sullivan County. (His birthplace is sometimes listed as Callicoon or Delaware, both also in Sul ...

Ballast
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ballast "did not ...
