Abbeville–Buigny-Saint-Maclou Aerodrome
The Abbeville Airfield () or Abbeville Aerodrome is an airfield serving Abbeville and located in Buigny-Saint-Maclou, north-northeast of Abbeville, both ''communes'' of the Somme ''département'' in the Picardie region of France. History It is not known when exactly the airfield was built, but it was in use with the British Expeditionary Forces in 1940. Detachments of No. 607 Squadron RAF with Gloster Gladiator biplanes were based here along with No. 151 Squadron RAF Hawker Hurricanes before they were withdrawn to English bases in June 1940 during the Battle of France. It was seized by the Luftwaffe and became a German Fliegerhorst. The Luftwaffe immediately began preparing for the Battle of Britain and the airfield became home to Zerstörergeschwader 76 (ZG 76) with Bf 110Cs, and later Fw 190As of II./Jagdgeschwader 26 (JG 26) 'Schlageter' in December 1941. Judging from the layout of the airfield, it was the Luftwaffe that upgraded the airfield with three concrete runways ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbeville
Abbeville (; ; ) is a commune in the Somme department and in Hauts-de-France region in northern France. It is the of one of the arrondissements of Somme.

The majority of the town is located on the east bank of the Somme, as well as on an island. It is located at the head of the Abbeville Canal, and is northwest of Amiens and approximately from Paris. It is also as the crow flies from the and the English Channel. In the medieval period, it was the lowest crossing point on the Somme and it was nearby that Edward III's army crossed shortly before the Battle of Crécy in 1346. Just halfway between Rouen and Lille, it is the historical capital of the County of Ponthieu and maritime Picardy.

Battle Of Britain
The Battle of Britain () was a military campaign of the Second World War, in which the Royal Air Force (RAF) and the Fleet Air Arm (FAA) of the Royal Navy defended the United Kingdom (UK) against large-scale attacks by Nazi Germany's air force, the Luftwaffe. It was the first major military campaign fought entirely by air forces."92 Squadron – Geoffrey Wellum." ''Battle of Britain Memorial Flight'' via ''raf.mod.uk.''. Retrieved: 17 November 2010, archived 2 March 2009.

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean Sea Level
A mean is a quantity representing the "center" of a collection of numbers and is intermediate to the extreme values of the set of numbers. There are several kinds of means (or "measures of central tendency") in mathematics, especially in statistics. Each attempts to summarize or typify a given group of data, illustrating the magnitude and sign of the data set. Which of these measures is most illuminating depends on what is being measured, and on context and purpose. The ''arithmetic mean'', also known as "arithmetic average", is 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 numbers are from observing a sample of a larger group, the arithmetic mean is termed the '' sample mean'' (\bar) to distinguish it from the group mean (or expected value) of the underlying distribution, denoted \mu or \mu_x. Outside probability and statistics, a wide rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevation
The elevation of a geographic location (geography), ''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 equipotential surface, surface (see Geodetic datum#Vertical datum, 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 ''three-dimensional space, 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 (volcano), Chimborazo have, respectively, the largest elevation and the largest ECEF, geocentric distance.

C-47 Skytrain
The Douglas C-47 Skytrain or Dakota ( RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. During the war the C-47 was used for troop transport, cargo, paratrooper, for towing gliders and military cargo parachute drops. The C-47 remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45–47. It was produced in approximately triple the numbers as the larger, much heavier payload Curtiss C-46 Commando, which filled a similar role for the U.S. military. Approximately 100 countries' armed forces have operated the C-47 with over 60 variants of the aircraft produced. As with the civilian DC-3, the C-47 remains in service, over 80 years after the type's introduction. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attach ...

Messerschmitt Bf 109
The Messerschmitt Bf 109 is a monoplane fighter aircraft that was designed and initially produced by the Nazi Germany, German aircraft manufacturer Messerschmitt#History, Bayerische Flugzeugwerke (BFW). Together with the Focke-Wulf Fw 190, the Bf 109 formed the backbone of the ''Luftwaffe's'' fighter force during the World War II. It was commonly called the Me 109 by Allied aircrew and some German aces/pilots, even though this was not the official model designation. The Bf 109 was designed by Willy Messerschmitt and Robert Lusser, who worked at BFW during the early to mid-1930s. It was conceived as an interceptor aircraft, interceptor. However, later models were developed to fulfill multiple tasks, serving as Escort fighter, bomber escort, fighter-bomber, day fighter, day-, night fighter, night-, all-weather fighter, ground-attack aircraft, and aerial reconnaissance aircraft. It was one of the most advanced fighters when the fighter first appeared, being furnished with an all-me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jagdgeschwader 26
''Jagdgeschwader'' 26 (JG 26) ''Schlageter'' was a German fighter-wing of World War II. It was named after Albert Leo Schlageter, a World War I veteran, Freikorps member, and posthumous Nazi martyr, arrested and executed by the French for sabotage in 1923. The wing fought predominantly against the Western Allies. Formed in May 1939, JG 26 spent the Phoney War period guarding Germany's western borders following the German invasion of Poland and the outbreak of World War II. In May and June 1940 it served in the Battle of Belgium and Battle of France. From July 1940 it operated over England in the Battle of Britain under the command of Adolf Galland, future '' General der Jagdflieger''. JG 26 remained in France and Belgium fighting against the RAF Fighter Command Circus offensive in 1941 and 1942, with considerable tactical success. In 1943 it faced the USAAF Eighth Air Force, and along with the rest of the Luftwaffe fighter force, was worn down over Western Euro ...

Focke-Wulf Fw 190
The Focke-Wulf Fw 190, nicknamed ''Würger'' (Shrike) is a German single-seat, single-engine fighter aircraft designed by Kurt Tank at Focke-Wulf in the late 1930s and widely used during World War II. Along with its well-known counterpart, the Messerschmitt Bf 109, the Fw 190 became the backbone of the (Fighter Force) of the . The twin-row BMW 801 radial engine that powered most operational versions enabled the Fw 190 to lift larger loads than the Bf 109, allowing its use as a day fighter, fighter-bomber, ground-attack aircraft and to a lesser degree, night fighter. The Fw 190A started flying operationally over France in August 1941 and quickly proved superior in all but turn radius to the Supermarine Spitfire (early Merlin-powered variants)#Mk V (Mk V (Types 331, 349 and 352)), Spitfire Mk. V, the main front-line fighter of the Royal Air Force (RAF), particularly at low and medium altitudes. The 190 maintained its superiority over Allies of World War II, Allied fighters until ...
