Royal Air Force
–
The Royal Air Force is the United Kingdoms aerial warfare force. Formed towards the end of the First World War on 1 April 1918, following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. The RAF describe its mission statement as, an agile, adaptable and capable Air Force that, person for person, is second to none, and that makes a decisive air power contribution in support of the UK Defence Mission. The mission statement is supported by the RAFs definition of air power, Air power is defined as the ability to project power from the air and space to influence the behaviour of people or the course of events. Today the Royal Air Force maintains a fleet of various types of aircraft. The majority of the RAFs rotary-wing aircraft form part of the tri-service Joint Helicopter Command in support of ground forces, most of the RAFs aircraft and personnel are based in the UK, with many others serving on operations or at long-established overseas bases. It was founded on 1 April 1918, with headquarters located in the former Hotel Cecil, during the First World War, by the amalgamation of the Royal Flying Corps, at that time it was the largest air force in the world. The RAFs naval aviation branch, the Fleet Air Arm, was founded in 1924, the RAF developed the doctrine of strategic bombing which led to the construction of long-range bombers and became its main bombing strategy in the Second World War. The RAF underwent rapid expansion prior to and during the Second World War, under the British Commonwealth Air Training Plan of December 1939, the air forces of British Commonwealth countries trained and formed Article XV squadrons for service with RAF formations. Many individual personnel from countries, and exiles from occupied Europe. By the end of the war the Royal Canadian Air Force had contributed more than 30 squadrons to serve in RAF formations, additionally, the Royal Australian Air Force represented around nine percent of all RAF personnel who served in the European and Mediterranean theatres. In the Battle of Britain in 1940, the RAF defended the skies over Britain against the numerically superior German Luftwaffe, the largest RAF effort during the war was the strategic bombing campaign against Germany by Bomber Command. Following victory in the Second World War, the RAF underwent significant re-organisation, during the early stages of the Cold War, one of the first major operations undertaken by the Royal Air Force was in 1948 and the Berlin Airlift, codenamed Operation Plainfire. Before Britain developed its own nuclear weapons the RAF was provided with American nuclear weapons under Project E and these were initially armed with nuclear gravity bombs, later being equipped with the Blue Steel missile. Following the development of the Royal Navys Polaris submarines, the nuclear deterrent passed to the navys submarines on 30 June 1969. With the introduction of Polaris, the RAFs strategic nuclear role was reduced to a tactical one and this tactical role was continued by the V bombers into the 1980s and until 1998 by Tornado GR1s. For much of the Cold War the primary role of the RAF was the defence of Western Europe against potential attack by the Soviet Union, with many squadrons based in West Germany. With the decline of the British Empire, global operations were scaled back, despite this, the RAF fought in many battles in the Cold War period

United States Army Air Forces
–
Each of these forces had a commanding general who reported directly to the Army Chief of Staff. S. Army to control its own installations and support personnel, the peak size of the AAF during the Second World War was over 2.4 million men and women in service and nearly 80,000 aircraft by 1944, and 783 domestic bases in December 1943. By V-E Day, the Army Air Forces had 1.25 million men stationed overseas, in its expansion and conduct of the war, the AAF became more than just an arm of the greater organization. By the end of World War II, the Army Air Forces had become virtually an independent service and this contrast between theory and fact is. fundamental to an understanding of the AAF. Gen. Billy Mitchell that led to his later court-martial, a strategy stressing precision bombing of industrial targets by heavily armed, long-range bombers emerged, formulated by the men who would become its leaders. Since 1920, control of units had resided with commanders of the corps areas. Both were created in 1933 when a conflict with Cuba seemed possible following a coup détat. Activation of GHQ Air Force represented a compromise between strategic airpower advocates and ground force commanders who demanded that the Air Corps mission remain tied to that of the land forces. GHQ Air Force organized combat groups administratively into a force of three wings deployed to the Atlantic, Pacific, and Gulf coasts but was small in comparison to European air forces. Corps area commanders continued to control over airfields and administration of personnel. The expected activation of Army General Headquarters prompted Army Chief of Staff George C. Marshall to request a study from Chief of the Air Corps Maj. Gen. Henry H. Arnold resulting on 5 October 1940 in a proposal for creation of an air staff, unification of the air arm under one commander, and equality with the ground and supply forces. Marshall implemented a compromise that the Air Corps found entirely inadequate, naming Arnold as acting Deputy Chief of Staff for Air but rejecting all organizational points of his proposal. GHQ Air Force instead was assigned to the control of Army General Headquarters, although the latter was a training and not an operational component, when it was activated in November 1940. A division of the GHQ Air Force into four air defense districts on 19 October 1940 was concurrent with the creation of air forces to defend Hawaii. The air districts were converted in March 1941 into numbered air forces with an organization of 54 groups. Marshall had come to the view that the air forces needed a simpler system, Arnold and Marshall agreed that the AAF would enjoy a general autonomy within the War Department until the end of the war, while its commanders would cease lobbying for independence. Marshall, a proponent of airpower, left understood that the Air Force would likely achieve its independence following the war

Leicestershire
–
Leicestershire is a landlocked county in the English Midlands. The border with most of Warwickshire is Watling Street, the county has a population of just under 1 million with over half the population living in Leicesters built-up area. Leicestershire was recorded in the Domesday Book in four wapentakes, Guthlaxton, Framland, Goscote and these later became hundreds, with the division of Goscote into West Goscote and East Goscote, and the addition of Sparkenhoe hundred. In 1087, the first recorded use of the name was as Laegrecastrescir, Leicestershires external boundaries have changed little since the Domesday Survey. These actions were reversed on 1 April 1997, when Rutland, Rutland became a distinct Ceremonial County once again, although it continues to be policed by Leicestershire Constabulary. The symbol of the county council, Leicestershire County Cricket Club, Leicestershire is considered to be the birthplace of fox hunting as it is known today. Hugo Meynell, who lived in Quorn, is known as the father of fox hunting, Melton Mowbray and Market Harborough have associations with fox hunting, as has neighbouring Rutland. A large part of the north-west of the county, around Coalville, the highest point of the county is Bardon Hill at 278 metres, which is also a Marilyn. The lowest point is about 24. 8m, north of Bottesford where the River Devon leaves Leicestershire, the population of Leicestershire is 609,578 people. The county covers an area of 2,084 km2 and its largest population centre is the city of Leicester, followed by the town of Loughborough. Other large towns include Ashby-de-la-Zouch, Coalville, Hinckley, Market Harborough, Melton Mowbray, Oadby, Wigston, some of the larger of villages are, Burbage Birstall, Broughton Astley, Castle Donington, Kibworth Beauchamp, Great Glen, Ibstock, Countesthorpe and Kegworth. One of the most rapidly expanding villages is Anstey, which has seen a large number of development schemes. The United Kingdom Census 2001 showed a resident population for Leicester of 279,921. Approximately 62,000 were aged under 16,199,000 were aged 16–74,76. 9% of Leicesters population claim they have been born in the UK, according to the 2001 UK Census. Mid-year estimates for 2006 indicate that the population of the City of Leicester stood at 289,700 making Leicester the most populous city in East Midlands, the population density is 3, 814/km2 and for every 100 females, there were 92.9 males. Of those aged 16–74 in Leicester,38. 5% had no academic qualifications,23. 0% of Leicesters residents were born outside of the United Kingdom, more than double than the English average of 9. 2%. Engineering has long been an important part of the economy of Leicestershire, John Taylor Bellfounders continues a history of bellfounding in Loughborough since the 14th century. In 1881 John Taylors cast the largest bell in Britain, Great Paul, snibston Discovery Park is built on one of three coal mines that operated in Coalville from the 1820s until 1986

Runway
–
According to the International Civil Aviation Organization, a runway is a defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft. Runways may be a surface or a natural surface. Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the heading in decadegrees. This heading differs from true north by the magnetic declination. A runway numbered 09 points east, runway 18 is south, runway 27 points west, when taking off from or landing on runway 09, a plane would be heading 90°. A runway can normally be used in both directions, and is named for each separately, e. g. runway 33 in one direction is runway 15 when used in the other. The two numbers usually differ by 18, Runway Zero Three Left becomes Runway Two One Right when used in the opposite direction. In some countries, if parallel runways are too close to each other, at large airports with four or more parallel runways some runway identifiers are shifted by 10 degrees to avoid the ambiguity that would result with more than three parallel runways. For example, in Los Angeles, this results in runways 6L, 6R, 7L. At Dallas/Fort Worth International Airport, there are five parallel runways, named 17L, 17C, 17R, 18L, for clarity in radio communications, each digit in the runway name is pronounced individually, runway three six, runway one four, etc. A leading zero, for example in runway zero six or runway zero one left, is included for all ICAO, however, most U. S. civil aviation airports drop the leading zero as required by FAA regulation. This also includes some military airfields such as Cairns Army Airfield and this American anomaly may lead to inconsistencies in conversations between American pilots and controllers in other countries. It is very common in a such as Canada for a controller to clear an incoming American aircraft to, for example, runway 04. In flight simulation programs those of American origin might apply U. S. usage to airports around the world, for example, runway 05 at Halifax will appear on the program as the single digit 5 rather than 05. Runway designations change over time because the magnetic poles slowly drift on the Earths surface, depending on the airport location and how much drift takes place, it may be necessary over time to change the runway designation. As runways are designated with headings rounded to the nearest 10 degrees, for example, if the magnetic heading of a runway is 233 degrees, it would be designated Runway 23. If the magnetic heading changed downwards by 5 degrees to 228, if on the other hand the original magnetic heading was 226, and the heading decreased by only 2 degrees to 224, the runway should become Runway 22. Because the drift itself is slow, runway designation changes are uncommon

Asphalt
–
Asphalt, also known as bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in deposits or may be a refined product. Until the 20th century, the term asphaltum was also used, the word is derived from the Ancient Greek ἄσφαλτος ásphaltos. The primary use of asphalt/bitumen is in construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt, the terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt is the carefully refined residue from the process of selected crude oils. Outside the United States, the product is often called bitumen, geologists often prefer the term bitumen. Common usage often refers to forms of asphalt/bitumen as tar. Naturally occurring asphalt/bitumen is sometimes specified by the crude bitumen. Its viscosity is similar to that of cold molasses while the material obtained from the distillation of crude oil boiling at 525 °C is sometimes referred to as refined bitumen. The Canadian province of Alberta has most of the reserves of natural bitumen, covering 142,000 square kilometres. Additionally, most natural bitumens contain organosulfur compounds, resulting in a sulfur content of up to 4%. Nickel and vanadium are found in the <10 ppm level, as is typical of some petroleum, the substance is soluble in carbon disulfide. It is commonly modelled as a colloid, with asphaltenes as the dispersed phase, and it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large. Asphalt/bitumen can sometimes be confused with tar, which is a visually similar black. During the early and mid-20th century when town gas was produced, coal tar was a readily available byproduct, the addition of tar to macadam roads led to the word tarmac, which is now used in common parlance to refer to road-making materials. However, since the 1970s, when natural gas succeeded town gas, other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar. Pitch is another term used at times to refer to asphalt/bitumen

Lincolnshire
–
Lincolnshire is a county in the east of England. It also borders Northamptonshire in the south for just 20 yards, Englands shortest county boundary, the county town is Lincoln, where the county council has its headquarters. The ceremonial county of Lincolnshire is composed of the county of Lincolnshire. Therefore, part of the county is in the Yorkshire and the Humber region of England. The county is the second-largest of the English ceremonial counties and one that is predominantly agricultural in land use, the county is fifth largest of the two-tier counties, as the unitary authorities of North Lincolnshire and North East Lincolnshire are not included. The county can be broken down into a number of geographical sub-regions including, Lincolnshire derived from the merging of the territory of the ancient Kingdom of Lindsey with that controlled by the Danelaw borough of Stamford. For some time the county was called Lindsey, and it is recorded as such in the 11th-century Domesday Book. In 1888 when county councils were set up, Lindsey, Holland and these survived until 1974, when Holland, Kesteven, and most of Lindsey were unified into Lincolnshire. A local government reform in 1996 abolished Humberside, and the south of the Humber was allocated to the unitary authorities of North Lincolnshire. These two areas became part of Lincolnshire for ceremonial such as the Lord-Lieutenancy, but are not covered by the Lincolnshire police and are in the Yorkshire. The remaining districts of Lincolnshire are Boston, East Lindsey, Lincoln, North Kesteven, South Holland, South Kesteven and they are part of the East Midlands region. Lincolnshire is home to Woolsthorpe Manor, birthplace and home of Sir Isaac Newton and he attended The Kings School, Grantham and its library has preserved his signature, applied to a window sill when he was a teenager. Lincolnshire is an area, growing large amounts of wheat, barley, sugar beet. In South Lincolnshire, where the soil is rich in nutrients, some of the most common crops include potatoes, cabbages, cauliflowers. Most such companies are long gone, and Lincolnshire is no longer an engineering centre, however, as a result of the current economic climate some food production facilities have closed down, this has caused some reduction in the levels of migrant workers. The large number of people from Portugal is still obvious in the town of Boston. A coalition of Conservatives, Liberal Democrats and Independents currently controls Lincolnshire County Council, the Conservative Party comfortably controlled the County Council following the 2009 local elections, in which they increased their majority to 43 seats. The Labour Party lost a total of 15 seats including 7 in Lincoln, the Lincolnshire Independents gained a total of four seats, although one of their number moved to the Conservative group during 2010, increasing the number of Conservative seats to 61
