Aviation Accidents And Incidents In Botswana
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 ...

LZ 129 Hindenburg
LZ 129 ''Hindenburg'' (; Registration: D-LZ 129) was a German commercial passenger-carrying rigid airship, the lead ship of the ''Hindenburg'' class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company ( ''Luftschiffbau Zeppelin GmbH'') on the shores of Lake Constance in Friedrichshafen, Germany, and was operated by the German Zeppelin Airline Company (''Deutsche Zeppelin-Reederei''). It was named after Field Marshal Paul von Hindenburg, who was President of Germany from 1925 until his death in 1934. The airship flew from March 1936 until it was destroyed by fire 14 months later on May 6, 1937, while attempting to land at Lakehurst Naval Air Station in Manchester Township, New Jersey, at the end of the first North American transatlantic journey of its second season of service. This was the last of the great airship disasters; it was preceded by the crashes of the British R38, the US airship ''Roma ...

LZ 127 Graf Zeppelin
LZ 127 ''Graf Zeppelin'' () was a German passenger-carrying, hydrogen-filled rigid airship that flew from 1928 to 1937. It offered the first commercial transatlantic passenger flight service. Named after the German airship pioneer Ferdinand von Zeppelin, a count () in the German nobility, it was conceived and operated by Dr. Hugo Eckener, the chairman of Luftschiffbau Zeppelin. ''Graf Zeppelin'' made 590 flights totalling almost 1.7 million kilometres (over 1 million miles). It was operated by a crew of 36, and could carry 24 passengers. It was the longest and largest airship in the world when it was built. It made the first circumnavigation of the world by airship, and the first nonstop crossing of the Pacific Ocean by air; its range was enhanced by its use of Blau gas as a fuel. It was built using funds raised by public subscription and from the German government, and its operating costs were offset by the sale of special postage stamps to collectors, the support of the ...

Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor Count Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins as bombers and as scouts, resulting in over 500 deaths in bombing raids in Britain. The defeat of Germany in 1918 temporarily slowed the airship business. Although DELAG establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rigid Airship
A rigid airship is a type of airship (or dirigible) in which the envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps (also called pressure airships) and semi-rigid airships. Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschiffbau Zeppelin company. In 1900, Count Ferdinand von Zeppelin successfully performed the maiden flight of his first airship; further models quickly followed. Prior to the First World War, Germany was a world leader in the field, largely attributable to the work of von Zeppelin and his Luftschiffbau Zeppelin company. During the conflict, rigid airships were tasked with various military duties, which included their participation in Germany's strategic bombing campaign. Numerous rigid airships were produced and employed with relative commercial success between the 1900s and the late 1930s. The ...

Jean-Pierre Blanchard
Jean-Pierre rançoisBlanchard (4 July 1753 – 7 March 1809) was a French inventor, best known as a pioneer of gas balloon flight, who distinguished himself in the conquest of the air in a balloon, in particular the first crossing of the English Channel, on 7 January 1785. Biography 1784 - Flights in Paris Blanchard made his first successful balloon flight in Paris on 2 March 1784, in a hydrogen gas balloon launched from the Champ de Mars. The first successful manned balloon flight had taken place on 21 November 1783, when Pilâtre de Rozier and the Marquis d'Arlandes took off at Palace of Versailles in a free-flying hot air balloon constructed by the Montgolfier brothers. The first manned hydrogen balloon flight had taken place on 1 December 1783, when Professor Jacques Charles and Nicolas-Louis Robert launched '' La Charlière'' from the Jardin des Tuileries in Paris. Blanchard's flight nearly ended in disaster, when one spectator (Dupont de Chambon, a contemporary of Napole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air 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, 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'' 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 engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montgolfier Brothers
The Montgolfier brothers – Joseph-Michel Montgolfier (; 26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (; 6 January 1745 – 2 August 1799) – were aviation pioneers, balloonists and paper manufacturers from the commune Annonay in Ardèche, France. They invented the ''Montgolfière''-style hot air balloon, globe aérostatique, which launched the first confirmed piloted ascent by humans in 1783, carrying Jacques-Étienne. Joseph-Michel also invented the self-acting hydraulic ram (1796) and Jacques-Étienne founded the first paper-making vocational school. Together, the brothers invented a process to manufacture transparent paper. Early years Joseph-Michel and Jacques-Étienne Montgolfier were born into a family of paper manufacturers. Their parents were Pierre Montgolfier (1700–1793) and Anne Duret (1701–1760), who had 16 children. Pierre Montgolfier established his eldest son, Raymond (1730–1772), as his successor. Joseph-Michel was the 12th chil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eilmer Of Malmesbury
Eilmer of Malmesbury (also known as Oliver due to a scribe's miscopying, or Elmer, or Æthelmær) was an 11th-century English Benedictine monk best known for his early attempt at a gliding flight using wings. Life Eilmer was a monk of Malmesbury Abbey who wrote on astrology. All that is known of him is from the ''Gesta regum Anglorum'' (Deeds of the English Kings), written by the eminent medieval historian William of Malmesbury in about 1125. Being a fellow monk of the same abbey, William almost certainly obtained his account directly from people who knew Eilmer when he was an old man. Later scholars, such as the American historian of technology Lynn White, have attempted to estimate Eilmer's date of birth based on a quotation in William's ''Deeds'' about Halley's Comet, which appeared in 1066. However, William recorded Eilmer's quotation not to establish his age, but to show that a prophecy was fulfilled when the Normans invaded England. If Eilmer had seen Halley's Comet ...
