Edward R. Armstrong
Edward Robert Armstrong (1876–1955) was a Canadian-American engineer and inventor who in 1927 proposed a series of "seadrome" floating airport platforms for airplanes to land on and refuel for transatlantic flights. While his original concept was made obsolete by long-range aircraft that did not need such refueling points, the idea of an anchored deep-sea platform was later applied to use for floating oil rigs. Biography * Armstrong was born in 1876 in Guelph, Ontario. * He moved to the United States and worked in Texas in the early 1900s, developing oil-well-drilling machinery. * In 1909 he went to St. Louis, Missouri as an automotive and aviation engineer. * In 1916 he went to DuPont to work on the construction of their nitrocellulose plant in Hopewell, Virginia. He was then promoted to chief of the plant's mechanical research department. * In 1924 he quit DuPont to work full-time on his "seadrome" project. In 1926 he incorporated the "Armstrong Seadrome Development Compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Modern Mechanix
''Mechanix Illustrated'' was an American printed magazine that was originally published by Fawcett Publications. Its title was founded in 1928 to compete against the older ''Popular Science'' and ''Popular Mechanics''. Billed as "The How-To-Do Magazine," ''Mechanix Illustrated'' (''MI'') aimed to guide readers through various projects from home improvements and advice on repairs to "build-your-own (sports car, telescope, helicopter, etc)." It was headquartered in New York City. History and profile From its debut in 1928, it went through a number of permutations over the years, being called at various points in its life, ''Modern Mechanics and Inventions'', ''Modern Mechanix and Inventions'', ''Modern Mechanix'', ''Mechanix Illustrated'', ''Home Mechanix'', and, in its final incarnation, ''Today's Homeowner''. Although it featured many how-to articles, the most eagerly awaited and read features were Tom McCahill's monthly automobile tests which ran from the late 1940s to the earl ...

History Detectives
''History Detectives'' is a documentary television series on Public Broadcasting Service, PBS. It features investigations made by members of a small team of researchers to identify and/or authenticate items which may have historical significance or connections to important historical events, and to answer specific questions brought to them about these artifacts. Common subjects are family heirlooms and historical structures. Its stated mission is "exploring the complexities of historical mysteries, searching out the facts, myths and conundrums that connect local folklore, family legends and interesting objects." Over its first decade, the series featured a team of several "detectives": originally Wes Cowan, Elyse Luray, Gwendolyn WGwen Wright, and Tukufu Zuberi, later joined by Eduardo Obregón Pagán, Eduardo Pagán. Following a hiatus, the program returned in summer 2014 in a different format, with hosts Zuberi and Cowan joined by Kaiama Glover, as ''History Detectives: Special ...

Project Habakkuk
Project Habakkuk or Habbakuk (spelling varies) was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete (a mixture of wood pulp and ice) for use against German U-boats in the mid-Atlantic, which were beyond the flight range of land-based planes at that time. The plan was to create what would have been the largest ship ever at 600 m long and would indeed have been much bigger than even USS ''Enterprise'', the largest naval vessel ever, at 342 m long.The idea came from Geoffrey Pyke, who worked for Combined Operations Headquarters. After promising scale tests and the creation of a prototype on Patricia Lake, Jasper National Park, in Alberta, Canada, the project was shelved due to rising costs, added requirements, and the availability of longer-range aircraft and escort carriers which closed the Mid-Atlantic gap that the project was intended to address. History Initial concept Geoffrey Pyke was an old friend of J. D. Bernal and ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lily And Clover
''Lily'' and ''Clover'' were two experimental floating airfields tested towards the end of the Second World War by the British Admiralty. Based on a similar concept to the Mulberry harbour used for the Normandy landings in 1944, ''Lily'' and ''Clover'' were two different types of floating airstrips that would allow the Royal Navy to operate aircraft before a shore base is secured and removed the need for an aircraft carrier. ''Lily'' was a collection of flotation units developed for the floating roadways used in the Mulberry harbour. Each was six feet across, plates being fitted on the top to form the runway. The complete structure could be towed and weighed 5,000 tons, taking 400 man-hours to construct. ''Clover'' was built mainly of wood with wooden deck planking which could take a load of eight tons. It weighed more than Lily at 5,200 tons but would take 21,000 man-hours to assemble. The resulting runway was long and wide with of parking area and for storage and mainte ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
