Spy Basket
The spy gondola, spy basket, observation car or sub-cloud car (german: Spähgondel or ) is a crewed vessel that an airship hiding in cloud cover could lower several hundred metres to a point below the clouds in order to inconspicuously observe the ground and help navigate the airship. It was a byproduct of ''Peilgondel'' development (a gondola to weight an airship's radio-locating antenna). They were used almost exclusively by the Germans in the First World War on their military airships. Development The ''Peilgondel'' was developed by Paul Jaray to act as a heavy plumbbob for an airship's radio antenna. A free-hanging antenna wire would move and flex in the wind hindering communications; the added weight reduced this movement. Jaray then developed the ''Peilgondel'' further into a crewed spy gondola. Use Spy baskets were used on, among others, Schütte-Lanz and Zeppelin airships. , it was not always certain which airships used them: the blueprints for LZ 62 (L 30) and LZ 72 ...

Observatory Car Suspended From Zeppelin Scientific American 1916-12-23 Crop5
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Espionage Devices
Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence) from non-disclosed sources or divulging of the same without the permission of the holder of the information for a tangible benefit. A person who commits espionage is called an ''espionage agent'' or ''spy''. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law. Espionage is often part of an institutional effort by a government or commercial concern. However, the term tends to be associated with state spying on potential or actual enemies for military purposes. Spying involving corporations is known as industrial espionage. One of the most effective ways to gathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation History Of Germany
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Airship Technology
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air Powered aircraft, under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the Chitty Bang Bang (airship), ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Components
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air bal ...

Charley's War
''Charley's War'' was a British comic strip about the First World War, written by Pat Mills and drawn by Joe Colquhoun. It was originally published in ''Battle Picture Weekly'' from January 1979 to October 1986. Though later parts of the story covered the Russian Civil War (and, in episodes written by Scott Goodall, the early part of the Second World War), Pat Mills has stated that Charley's story should end at the end of the First World War, and this has been reflected in the collections published by Titan Comics. Publishing history Described by Andrew Harrison as "the greatest British comic strip ever created", ''Charley's War'' tells the story of an underage British soldier called Charley Bourne. Charley joins the British Army during World War I at the age of 16 (having lied about his age and told the recruiting officers that he was 18; they conveniently overlook the fact that Charley gives his date of birth on his application form as 1900), and is quickly thrust into the ...

Hell's Angels (film)
''Hell's Angels'' is a 1930 American pre-Code independent epic war film directed and produced by Howard Hughes and director of dialogue James Whale. Written by Harry Behn and Howard Estabrook and starring Ben Lyon, James Hall and Jean Harlow, it was released through United Artists. It follows two dissimilar brothers, both members of the British Royal Flying Corps during the First World War. The film was originally shot as a silent film, but it was still unfinished after a year and a half, by which time ''The Jazz Singer'' had premiered, signaling the start of the sound era. Hughes converted his film to sound. The original female lead, Norwegian-American Greta Nissen, had to be replaced due to her accent. Harlow became a major star as her successor. The production took three years (1927–1930) and Hughes spared no expense, so that despite being one of the highest-grossing films of the early sound era, it did not recoup its exorbitant $2.8 million cost. Hughes and pilot Harry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperial War Museum
Imperial War Museums (IWM) is a British national museum organisation with branches at five locations in England, three of which are in London. Founded as the Imperial War Museum in 1917, the museum was intended to record the civil and military war effort and sacrifice of Britain and British Empire, its Empire during the First World War. The museum's remit has since expanded to include all conflicts in which British or Commonwealth forces have been involved since 1914. As of 2012, the museum aims "to provide for, and to encourage, the study and understanding of the history of modern war and 'wartime experience'." Originally housed in the Crystal Palace at Sydenham Hill, the museum opened to the public in 1920. In 1924, the museum moved to space in the Imperial Institute in South Kensington, and finally in 1936, the museum acquired a permanent home that was previously the Bethlem Royal Hospital in Southwark. The outbreak of the Second World War saw the museum expand both its coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
