List Of Missing Aircraft
This list of missing aircraft includes aircraft that have disappeared and whose locations are unknown. According to ''Annex 13'' of the International Civil Aviation Organization, an aircraft is considered to be missing "when the official search has been terminated and the wreckage has not been located". However, there still remains a "grey area" on how much wreckage needs to be found for a plane to be declared "recovered". This list does not include every aviator, or even every air passenger that has ever gone missing as these are separate categories. In the tables below, each missing aircraft is defined (in the Aircraft column) using one or more identifying features. If the aircraft was known by a custom or personalized name (e.g. ''Pathfinder''), that name is presented first (in italics) followed by the aircraft type (in parentheses). The make of aircraft, although not necessarily a unique identifier, is also provided where appropriate. Aircraft registrations began to be us ...

Walter Powell (politician)
Walter Powell (17 April 1842 – 10 December 1881) was a Welsh colliery owner and Conservative politician who sat in the House of Commons from 1868 to 1881. He was carried out over the English Channel in a balloon and never seen again. Early life and education Powell was the son of Thomas Powell of Newport, Monmouthshire and his wife Anne Williams, daughter of Walter Williams. His father had interests in coal, railways and shipping and was one of the world's largest coal producers in the 1840s. His company now operates under the name of Powell Duffryn plc in the areas of ports and engineering, although the coal and railway interests were nationalised in the 1940s. Powell was the youngest of three brothers and had three sisters. He was educated at Rugby School and continued in the family business. In 1869 he had to journey to Africa to take care of family matters after the murders of his brother Thomas and Thomas's wife and son by robbers on a trip to Abyssinia. Powell was a J ...

Semi-rigid Airship
A semi-rigid airship is an airship which has a stiff keel or truss supporting the main envelope along its length. The keel may be partially flexible or articulated and may be located inside or outside the main envelope. The outer shape of the airship is maintained by gas pressure, as with the non-rigid "blimp". Semi-rigid dirigibles were built in significant quantity from the late 19th century but in the late 1930s they fell out of favour along with rigid airships. No more were constructed until the semi-rigid design was revived by the Zeppelin NT in 1997. Semi-rigid construction is lighter-weight than the outer framework of a rigid airship, while it allows greater loading than a non-rigid type. Principle More or less integrally attached to the hull are the gondola, engines and sometimes the empennage (tail). The framework has the task of distributing the suspension loads of these attachments and the lifting gas loads evenly throughout the whole hull's surface and may also ...

Patrie (airship)
The Lebaudy ''Patrie'' was a semi-rigid airship built for the French army in Moisson, France, by sugar producers Lebaudy Frères. Designed by Henri Julliot, Lebaudy's chief engineer, the ''Patrie'' was completed in November 1906 and handed over to the military the following month. The ''Patrie'' bears the distinction of being the first airship ordered for military service by the French army. In 1907, from her base at Chalais-Meudon near Paris, a successful series of military manoeuvres was conducted with the airship by the military command, which included a visit by France's President of the Council Georges Clemenceau. Following the successful completion of these operations, in November 1907 the ''Patrie'' was transferred under her own power to her operational base at Verdun, near the German border. Due to a mechanical fault, the ''Patrie'' became stranded away from her base on 29 November 1907 in Souhesmes. During a storm on 30 November she was torn loose from her t ...

Andrée's Arctic Balloon Expedition
Andrée's Arctic balloon expedition of 1897 was a failed effort to reach the North Pole, resulting in the deaths of all three Swedish expedition members, S. A. Andrée, Knut Frænkel, and Nils Strindberg. Andrée, the first Swedish balloonist, proposed a voyage by hydrogen balloon from Svalbard to either Russia or Canada, which was to pass, with luck, straight over the North Pole on the way. The scheme was received with patriotic enthusiasm in Sweden, a northern nation that had fallen behind in the race for the North Pole. Andrée ignored many early signs of the dangers associated with his balloon plan. Being able to steer the balloon to some extent was essential for a safe journey, but there was much evidence that the drag-rope steering technique he had invented was ineffective. Worse, the polar balloon (''Eagle'') was delivered directly to Svalbard from its manufacturer in Paris without being tested. When measurements showed it to be leaking more than expected, Andrée fail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nils Strindberg
Nils Strindberg (4 September 1872 – October 1897) was a Swedish photographer and scientist. He was one of the three members of S. A. Andrée's ill-fated Arctic balloon expedition of 1897. Biography Nils Strindberg was born in Stockholm, Sweden. He was the son of wholesaler Johan Oscar Strindberg and Aurora Helena Rosalie Lundgren. His younger brother, Tore Strindberg (1882-1968), was a noted sculptor. His father's cousin was playwright and novelist, August Strindberg (1849–1912). Strindberg graduated from Norra Real in Stockholm during 1890. He received his Bachelor of Arts (''fil.kand.'') at Uppsala University in 1893. In 1895, received a post as lector at the Stockholm University. In the spring of 1896 he traveled to Paris to study gas balloon flight. Strindberg was invited to the Arctic balloon expedition of 1897 to create a photographic aerial record of the arctic. Before perishing on Kvitøya with Andrée and Knut Frænkel, Strindberg recorded on film their lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knut Frænkel
Knut Hjalmar Ferdinand Frænkel (14 February 1870 – c. 10 October 1897) was a Swedish engineer and arctic explorer who perished in the Arctic balloon expedition of 1897 of S. A. Andrée in 1897. Biography Frænkel was born in Karlstad, Sweden. He was a major in the Road and Waterway Construction Service Corps, and grew up in mountainous Jämtland in the eastern middle part of Sweden, where he acquired an interest in outdoor activities and sports. He later went to the Palmgren School in Stockholm and graduated with a civil engineering degree from the Royal Institute of Technology in 1896, and was preparing himself to enter the Army engineers when the chance came up in 1897 to join S. A. Andrée's planned balloon expedition to the North Pole. The third participant was Nils Strindberg. Frænkel replaced the meteorologist Nils Gustaf Ekholm, who had participated in the preparations but dropped out in the last moment, critical of the construction of the balloon. During the ba ...

Structural Integrity And Failure
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively. It assures that the construction will perform its designed function during reasonable use, for as long as its intended life span. Items are constructed with structural integrity to prevent catastrophic failure, which can result in injuries, severe damage, death, and/or monetary losses. ''Structural failure'' refers to the loss of structural integrity, or the loss of load-carrying capacity in either a structural component or the structure itself. Structural failure is initiated wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malmesbury (UK Parliament Constituency)
Malmesbury was a parliamentary borough in Wiltshire, which elected two Members of Parliament (MPs) to the House of Commons from 1275 until 1832, and then one member from 1832 until 1885, when the borough was abolished. History The borough was represented in Parliament from 1275. The constituency originally returned two members, but representation was reduced to one in the Great Reform Act of 1832 until the constituency was finally abolished in 1885.
