A-60 Beaumont-sur-Oise
Persan-Beaumont Airport (french: Aérodrome de Persan - Beaumont, ) is a regional airport in the Val-d'Oise department in Île-de-France in northern France. It is located northeast of Beaumont-sur-Oise, east-northeast of Persan, and north of Paris. The airport supports general aviation with no commercial airline service scheduled. History Beaumont Sur Oise was a pre-World War II French Air Force airfield with a concrete runway (05/23). The airfield was seized by the Germans in June 1940 during the Battle of France. It was used by the Luftwaffe only sparingly, with Luftlandegeschwader 1 (LLG 1), a glider unit being assigned to the airfield between April and May 1943, equipped with Henschel Hs 126 liaison aircraft; Dornier Do 17s to pull the units DFS 230 transport gliders. Later, in November and December 1943, Schlachtgeschwader 4 (SLG 4) operated Focke-Wulf Fw 190F/Gs as a ground-attack unit. Beaumont was attacked on several missions by the United States Army Air Forces Eig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DFS 230
The DFS 230 was a German transport glider operated by the Luftwaffe in World War II. It was developed in 1933 by the Deutsche Forschungsanstalt für Segelflug (DFS - "German Research Institute for Sailplane Flight") with Hans Jacobs as the head designer. The glider was the German inspiration for the British Hotspur glider and was intended for airborne assault operations. In addition to the pilot, the DFS-230 glider had room for nine men who sat close together on a narrow bench located in the middle of the fuselage (six facing forward, and four backward). Entry and exit to the cramped interior was by a single side door. The front passenger could operate its only armament, a machine gun. It was an assault glider, designed to land directly on top of its target, so it was equipped with a parachute brake. This allowed the glider to approach its target in a dive at an angle of eighty degrees and land within of its target. It could carry up to of cargo. It played significant roles ...

Advanced Landing Ground
Advanced Landing Grounds (ALGs) were temporary advance airfields constructed by the Allies during World War II during the liberation of Europe. They were built in the UK prior to the invasion and thereafter in northwest Europe from 6 June 1944 to V-E Day, 7 May 1945. Unlike the permanent airfields built in the United Kingdom and designed for the strategic bombardment of Germany, the tactical combat airfields on the continent were temporary, often improvised airfields to be used by the tactical air forces to support the advancing ground armies engaged on the battlefield. Once the front line moved out of range for the aircraft, the groups and squadrons moved up to newly built ALGs closer to the ground forces and left the ones in the rear for other support uses, or simply abandoned them. Overview When the Allies invaded Normandy on D-Day, Royal Air Force Airfield Construction Service engineers were among those in the initial assault waves. Their mission was to rapidly construc ...

Grass
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Mean Sea Level
There are several kinds of mean in mathematics Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics ..., especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value (magnitude (mathematics), magnitude and sign (mathematics), sign) of a given data set. For a data set, the ''arithmetic mean'', also known as "arithmetic average", is a measure of central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the data set were based on a series of observations obtained by sampling (statistics), sampling from a statistical population, the arithmetic mean is th ...

Elevation
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while ''altitude'' or ''geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and '' depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A-26 Invader
The Douglas A-26 Invader (designated B-26 between 1948 and 1965) is an American twin-engined light bomber and ground attack aircraft. Built by Douglas Aircraft Company during World War II, the Invader also saw service during several major Cold War conflicts. A limited number of highly modified United States Air Force aircraft served in Southeast Asia until 1969. It was a fast aircraft capable of carrying a large bomb load. A range of guns could be fitted to produce a formidable ground-attack aircraft.Wheeler 1992, p. 82. A redesignation of the type from A-26 to B-26 led to confusion with the Martin B-26 Marauder, which first flew in November 1940, some 20 months before the Douglas design's maiden flight. Although both aircraft were powered by the widely used Pratt & Whitney R-2800 Double Wasp 18-cylinder, double-row radial engine, they were completely different and separate designs, with some 5,300 Marauders produced to 2,503 Invaders. Design and development The A-26 was Dou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

B-26 Marauder
The Martin B-26 Marauder is an American twin-engined medium bomber that saw extensive service during World War II. The B-26 was built at two locations: Baltimore, Maryland, and Omaha, Nebraska, by the Glenn L. Martin Company. First used in the Pacific Theater of World War II in early 1942, it was also used in the Mediterranean Theater and in Western Europe. After entering service with the United States Army aviation units, the aircraft quickly received the reputation of a " widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach speeds, and when they slowed to speeds below those stipulated in the manual the aircraft would often stall and crash.Ethell 1995, p. 2 ...
