A folding wing is a wing configuration design feature of aircraft to save space and is typical of carrier-based aircraft that operate from the limited deck space of aircraft carriers . The folding allows the aircraft to occupy less space in a confined hangar because the folded wing normally rises over the fuselage decreasing the floor area of the aircraft. Vertical clearance is also limited in aircraft carrier hangar decks . In order to accommodate for this, some aircraft such as the Supermarine Seafire and Fairey Gannet have additional hinges to fold the wingtips downward, while others such as the A-5 Vigilante and S-3 Viking have folding tails . The F-14 Tomcat 's variable-sweep wings could be "overswept" to occupy less space.

124-411: Short Brothers , the world's first aircraft manufacturer, developed and patented folding wing mechanisms for biplane ship-borne aircraft like their Short Folder , the first patent being granted in 1913. The Folder's biplane wings were hinged so that they folded back horizontally alongside the fuselage, usually being held in place by latches projecting sideways from the rear of the fuselage . In 1935,

248-472: A Bronze Age bridge were found on the south River Thames foreshore, upstream from Vauxhall Bridge . Two of the timbers were radiocarbon dated to 1750–1285 BC. In 2010, foundations of a large timber structure, dated to 4800–4500 BC, were found on the Thames' south foreshore downstream from Vauxhall Bridge. Both structures are on the south bank of the Thames, where the now-underground River Effra flows into

372-560: A glider , and the other from Francis McClean , a member of the Aero Club who later bought several more aircraft from Short Brothers, and also acted as an unpaid test-pilot. At the end of 1908 Horace started work on the two designs, and in early 1909 construction was started of McClean's aircraft, the Short No.1 biplane . In March 1909 it was exhibited, without its fabric covering, at the first British Aero Show held at Olympia . Meanwhile,

496-656: A 350 ft (110 m) testing tank for testing hull and float designs. Shorts designed the floats used for the Supermarine S.4 and Gloster III seaplanes entered by the United Kingdom for the 1925 Schneider Trophy race. Alan Cobham 's de Havilland DH.50 (G-EBFO) was also fitted with Shorts floats at Rochester. On 30 June 1926, Cobham then started a flight to Australia from the Medway. Two de Havilland Giant Moths were fitted with Shorts floats at Rochester, and

620-595: A Belfast company in its entirety. In the meantime, in 1947, Short Brothers (Rochester and Bedford) Ltd. had merged with Short and Harland Limited to become Short Brothers and Harland Limited , with Oswald Short remaining as Life President. In the 1950s, Shorts was involved in much pioneering research, including designing and building the VTOL Short SC1 , the Short SB5 and the Short SB.4 Sherpa . Shorts built

744-415: A South African diplomat. In 1993 a Catholic sub-contractor at Shorts was shot dead and five others injured in a loyalist attack on a mini-bus full of Catholic workmen in an attack to discourage Catholics from taking jobs at Shorts. In 1937, Shorts established an airfield in central Belfast, beside the factory. This became Sydenham Airport and, from 1938 to 1939, was Belfast's main civilian airport. During

868-698: A contract for three balloons for the British Indian Army . The quality of their work impressed Colonel James Templer , superintendent of the Royal Balloon Factory , who introduced the brothers to Charles Rolls . Rolls commissioned them to build him a large balloon to compete in the 1906 Gordon Bennett Cup balloon race . More orders soon followed from other members of the Aero Club of Great Britain (later Royal Aero Club). In 1908, on hearing reports from Aero Club members who had seen

992-542: A larger area, similar in size to Greater London, although some outer districts are excluded and some just outside included. The Greater London boundary has been aligned to the M25 motorway in places. Further urban expansion is now prevented by the Metropolitan Green Belt , although the built-up area extends beyond the boundary in places, producing a separately defined Greater London Urban Area . Beyond this

1116-569: A major settlement for nearly 2,000 years. Its ancient core and financial centre , the City of London , was founded by the Romans as Londinium and has retained its medieval boundaries. The City of Westminster , to the west of the City of London, has been the centuries-long host of the national government and parliament . London grew rapidly in the 19th century , becoming the world's largest city at

1240-667: A military in parentheses. London London is the capital and largest city of both England and the United Kingdom , with a population of 8,866,180 in 2022. The wider metropolitan area is the largest in Western Europe , with a population of 14.9 million. London stands on the River Thames in southeast England, at the head of a 50-mile (80 km) estuary down to the North Sea , and has been

1364-576: A more rounded top of the fuselage that incorporated several gunner's positions. Dreaded by U-boats , it was claimed by the British propaganda people that the Germans called it "The Flying Porcupine" ( Fliegendes Stachelschwein in German), although no evidence supports their contention. In 1933, Shorts opened a new factory at Rochester Airport , which was becoming increasingly important for the landplanes

1488-402: A non-folding wing. It is heavier and has more complex connections for electrical , fuel , aerodynamic , and structural systems. Many naval helicopters have rotor blades that can be aligned over the fuselage to save space on board ships. Folding surfaces are rare among land-based designs and are used on aircraft that are too tall or too wide to fit inside service hangars. Examples include

1612-580: A number of Grumman-designed carrier aircraft, a version of which is still in use in the 21st century on the Grumman E-2 Hawkeye shipboard airborne early warning (AEW) aircraft and its C-2 Greyhound derivative. Another Grumman naval aircraft, the F-14 Tomcat , had variable-sweep wings that could be swept between 20° and 68° in flight. For parking, the wings could be "overswept" to 75°. A folding wing has some disadvantages compared to

1736-403: A population density of 802 per acre (325 per hectare). In addition to the growing number of stores selling goods, such as Harding, Howell & Co. —one of the first department stores —located on Pall Mall , the streets had scores of street sellers . London's overcrowded conditions led to cholera epidemics, claiming 14,000 lives in 1848, and 6,000 in 1866. Rising traffic congestion led to

1860-573: A population of 7,172,036 in 2001 and a population density of 11,760 inhabitants per square mile (4,542/km ). The extended area known as the London Metropolitan Region or the London Metropolitan Agglomeration, comprises a total area of 3,236 square miles (8,382 km ) has a population of 13,709,000 and a population density of 3,900 inhabitants per square mile (1,510/km ). Modern London stands on

1984-691: A renegotiated price due to the effect of the COVID-19 pandemic. Year of first flight in parentheses. Some of the early aircraft are designated using the Short sequence or constructors number which should not be confused with the similar type designations started at S.1 in 1924. Since becoming part of Bombardier Aerospace in 1989, focus is aerospace components rather than individual aircraft models, missiles or drones. Shorts' missile division, which evolved into Shorts Missile Systems (1993–2000, then sold), produced surface-to-air missiles . Year of first use by

2108-429: A second-hand coal gas filled balloon , and, with his brother Oswald , started a company to develop and manufacture balloons. In 1900, the two brothers visited the 1900 Paris Exposition ('World's Fair'), where they saw the balloons of Édouard Surcouf (of Société Astra ), who had developed a method of constructing truly spherical balloons. In 1902, the brothers started offering balloons for sale. They manufactured

2232-496: A statue of the brothers was unveiled in memory of their contribution to early aviation, by local artist Barbara Street to stand on the site of the Aero Club clubhouse at Muswell manor. By the outbreak of World War I Shorts were already building a variety of aircraft. Production really started to expand during the war, for example for the Short Admiralty Type 184 (or simply "Short S.184"). On 15 August 1915, during

2356-532: A strong influence on world art , entertainment, fashion , commerce, finance, education , healthcare , media , science, technology, tourism , transport , and communications. Despite a post- Brexit exodus of stock listings from the London Stock Exchange , London remains a European economic powerhouse, and one of the world's major financial centres . It hosts Europe's largest concentration of higher education institutions , some of which are

2480-551: A temperate oceanic climate ( Köppen : Cfb ). Rainfall records have been kept in the city since at least 1697, when records began at Kew . At Kew, the most rainfall in one month is 7.4 inches (189 mm) in November 1755 and the least is 0 inches (0 mm) in both December 1788 and July 1800. Mile End also had 0 inches (0 mm) in April 1893. The wettest year on record is 1903, with a total fall of 38.1 inches (969 mm) and

2604-593: A transatlantic airliner , but largely served the post-war Empire ( Commonwealth ) market, in competition with 4-engined land planes such as modified Avro Lancasters , Avro Lancastrian and Avro York . Tasman Empire Airways Limited (TEAL) operated the Coral Route from New Zealand to Fiji , the Cook Islands and Tahiti in the South Pacific, with Short Solent flying boats up to 1960. During

2728-699: Is 1,049.8 millibars (31.00 inHg) on 20 January 2020. Summers are generally warm, sometimes hot. London's average July high is 23.5 °C (74.3 °F). On average each year, London experiences 31 days above 25 °C (77.0 °F) and 4.2 days above 30.0 °C (86.0 °F). During the 2003 European heat wave , prolonged heat led to hundreds of heat-related deaths. A previous spell of 15 consecutive days above 32.2 °C (90.0 °F) in England in 1976 also caused many heat related deaths. A previous temperature of 37.8 °C (100.0 °F) in August 1911 at

2852-512: Is agreed that the name came into these languages from Common Brythonic ; recent work tends to reconstruct the lost Celtic form of the name as * Londonjon or something similar. This was then adapted into Latin as Londinium and borrowed into Old English. Until 1889, the name "London" applied officially only to the City of London , but since then it has also referred to the County of London and to Greater London . In 1993, remains of

2976-545: Is formed of two tiers: a citywide, strategic tier and a local tier. Citywide administration is coordinated by the Greater London Authority (GLA), while local administration is carried out by 33 smaller authorities. The GLA consists of two elected components: the mayor of London , who has executive powers , and the London Assembly , which scrutinises the mayor's decisions and can accept or reject

3100-760: Is headquartered in Thames House on the north bank of the River Thames and the foreign intelligence service ( MI6 ) is headquartered in the SIS Building on the south bank. Crime rates vary widely across different areas of London. Crime figures are made available nationally at Local Authority and Ward level. In 2015, there were 118 homicides, a 25.5% increase over 2014. Recorded crime has been rising in London, notably violent crime and murder by stabbing and other means have risen. There were 50 murders from

3224-592: Is held by an independent . The ministerial post of minister for London was created in 1994, however as of 2024, the post has been vacant. Policing in Greater London, with the exception of the City of London , is provided by the Metropolitan Police ("The Met"), overseen by the mayor through the Mayor's Office for Policing and Crime (MOPAC). The Met is also referred to as Scotland Yard after

3348-500: Is known as London . It is the capital of the United Kingdom and of England by convention rather than statute. The capital of England was moved to London from Winchester as the Palace of Westminster developed in the 12th and 13th centuries to become the permanent location of the royal court , and thus the political capital of the nation. Greater London encompasses a total area of 611 square miles (1,583 km ) an area which had

3472-523: Is the vast London commuter belt . Greater London is split for some purposes into Inner London and Outer London , and by the River Thames into North and South , with an informal central London area. The coordinates of the nominal centre of London, traditionally the original Eleanor Cross at Charing Cross near the junction of Trafalgar Square and Whitehall , are about 51°30′26″N 00°07′39″W  /  51.50722°N 0.12750°W  / 51.50722; -0.12750 .

Modern scientific analyses of the name must account for the origins of the different forms found in early sources: Latin (usually Londinium ), Old English (usually Lunden ), and Welsh (usually Llundein ), with reference to the known developments over time of sounds in those different languages. It

3720-671: The Air Ministry established a new aircraft factory at Belfast , and created a new company Short & Harland Ltd , owned 50% each by Harland and Wolff and Shorts. The first products of the new factory were 50 Bristol Bombays followed by 150 Handley-Page Hereford bombers . Shorts work on seaplanes eventually culminated in the Short Sandringham and Short Seaford , both based on the Empire/Sunderland boats. These flying boats had enough range to operate as

3844-685: The Battle of Britain , the Rochester factory was heavily bombed by the Luftwaffe , and several Stirlings and other aircraft were destroyed, and during Easter week of 1941, Belfast and the aircraft factory were subjected to the worst single air-raid the UK had seen outside London . To prevent raids from limiting production, satellite factories near Belfast were operated at Aldergrove and Maghaberry, producing 232 Stirlings between them. A temporary Short's factory

3968-482: The Battle of Gallipoli , a Short S.184 was the first aircraft to attack a ship with a live torpedo. Flying from HMS Ben-my-Chree , piloted by Flight Commander Charles Edmonds , it hit a Turkish supply ship in the Dardanelles . In terms of number built, the S.184 was Shorts' most successful pre- Second World War aircraft: over 900 were produced, many under licence by other manufacturers. A landplane version of

4216-540: The Black Death in the mid-14th century, London lost nearly a third of its population. London was the focus of the Peasants' Revolt in 1381. London was a centre of England's Jewish population before their expulsion by Edward I in 1290. Violence against Jews occurred in 1190, when it was rumoured that the new king had ordered their massacre after they had presented themselves at his coronation. In 1264 during

4340-544: The Boeing B-50 Superfortress and its folding tail. The Saab 37 Viggen and the Boeing 377 Stratocruiser have foldable rear fins that make them lower for entering hangars. The Boeing 777 (classic) twinjet wide-body airliner was offered with folding wingtips for confined airports, though this was never ordered. The new Boeing 777X features a shorter and simpler folding wingtip than was planned for

4464-533: The Canary Wharf development. This was born out of London's increasing role as an international financial centre in the 1980s. Located about 2 miles (3 km) east of central London, the Thames Barrier was completed in the 1980s to protect London against tidal surges from the North Sea . The Greater London Council was abolished in 1986, leaving London with no central administration until 2000 and

4588-672: The Corn Laws in 1846 was specifically aimed at weakening Dutch economic power. London then overtook Amsterdam as the leading international financial centre. With the onset of the Industrial Revolution in Britain, an unprecedented growth in urbanisation took place, and the number of High Streets (the primary street for retail in Britain) rapidly grew. London was the world's largest city from about 1831 to 1925 , with

4712-601: The Douglas TBD Devastator was the first aircraft to feature hydraulic folding wings, allowing the pilot to fold the wings from the cockpit without requiring other sailors to fold them manually. Since the monoplane supplanted the biplane in the late 1930s, virtually all fixed-wing aircraft designed for shipboard duty have been equipped with folding wings. Notable exceptions include the SBD Dauntless , F2A Buffalo , and A4D/A-4 Skyhawk (all USN types);

4836-568: The Georgian era , new districts such as Mayfair were formed in the west; new bridges over the Thames encouraged development in South London . In the east, the Port of London expanded downstream. London's development as an international financial centre matured for much of the 18th century. In 1762, George III acquired Buckingham House , which was enlarged over the next 75 years. During

4960-634: The King's Road , Chelsea and Carnaby Street . The role of trendsetter revived in the punk era. In 1965 London's political boundaries were expanded in response to the growth of the urban area and a new Greater London Council was created. During The Troubles in Northern Ireland, London was hit from 1973 by bomb attacks by the Provisional Irish Republican Army . These attacks lasted for two decades, starting with

London was plagued by disease in the early 17th century, culminating in the Great Plague of 1665–1666, which killed up to 100,000 people, or a fifth of the population. The Great Fire of London broke out in 1666 in Pudding Lane in the city and quickly swept through the wooden buildings. Rebuilding took over ten years and

5580-564: The New World . London became the main North Sea port, with migrants arriving from England and abroad. The population rose from about 50,000 in 1530 to about 225,000 in 1605. In the 16th century, William Shakespeare and his contemporaries lived in London during English Renaissance theatre . Shakespeare's Globe Theatre was constructed in 1599 in Southwark . Stage performances came to a halt in London when Puritan authorities shut down

5704-421: The Old Bailey bombing . Racial inequality was highlighted by the 1981 Brixton riot . Greater London's population declined in the decades after the Second World War, from an estimated peak of 8.6 million in 1939 to around 6.8 million in the 1980s. The principal ports for London moved downstream to Felixstowe and Tilbury , with the London Docklands area becoming a focus for regeneration, including

5828-424: The Second Barons' War , Simon de Montfort 's rebels killed 500 Jews while attempting to seize records of debts. During the Tudor period , the Reformation produced a gradual shift to Protestantism . Much of London property passed from church to private ownership, which accelerated trade and business in the city. In 1475, the Hanseatic League set up a main trading base ( kontor ) of England in London, called

5952-403: The Short Empire , the first of which was launched on 2 July 1936. The Empire was commissioned off the drawing board by Imperial Airways (later BOAC ), to operate the UK's Empire Airmail scheme. A year later Shorts won a British government defence contract for the Sunderland military patrol flying boat. Sharing a similar design, but incorporating some aerodynamic and hydrodynamic advances, and

6076-427: The Short Sperrin , a backup jet engine bomber design in case the V bomber projects failed, and the Short Seamew , a cheap-to-produce anti-submarine reconnaissance and attack aircraft intended for the Royal Navy Volunteer Reserve squadrons, but the Sperrin was not needed and the RNVR squadrons disbanded. In the 1950s, Shorts also received sub-contracts to build 150 English Electric Canberras , and on 30 October 1952,

6200-412: The Stalhof or Steelyard . It remained until 1853, when the Hanseatic cities of Lübeck , Bremen and Hamburg sold the property to South Eastern Railway . Woollen cloth was shipped undyed and undressed from 14th/15th century London to the nearby shores of the Low Countries . Yet English maritime enterprise hardly reached beyond the seas of north-west Europe . The commercial route to Italy and

6324-495: The Thames , its primary geographical feature, a navigable river which crosses the city from the south-west to the east. The Thames Valley is a flood plain surrounded by gently rolling hills including Parliament Hill , Addington Hills , and Primrose Hill . Historically London grew up at the lowest bridging point on the Thames. The Thames was once a much broader, shallower river with extensive marshlands ; at high tide, its shores reached five times their present width. Since

Other landmarks include Buckingham Palace , the London Eye , Piccadilly Circus , St Paul's Cathedral , Tower Bridge , and Trafalgar Square . The city has

6572-414: The Victorian era the Thames has been extensively embanked , and many of its London tributaries now flow underground . The Thames is a tidal river, and London is vulnerable to flooding. The threat has increased over time because of a slow but continuous rise in high water level caused by climate change and by the slow 'tilting' of the British Isles as a result of post-glacial rebound . London has

Oswald succeeded in persuading Horace to leave his job with Parsons, and in November 1908 they registered their partnership under the name Short Brothers. Two orders for aircraft were soon received, one from Charles Rolls, who ordered

6820-401: The 11th century, London was clearly the largest town in England. Westminster Abbey , rebuilt in Romanesque style by King Edward the Confessor , was one of the grandest churches in Europe. Winchester had been the capital of Anglo-Saxon England , but from this time London became the main forum for foreign traders and the base for defence in time of war. In the view of Frank Stenton : "It had

6944-434: The 18th century, London was said to be dogged by crime, and the Bow Street Runners were established in 1750 as a professional police force. Epidemics during the 1720s and 30s saw most children born in the city die before reaching their fifth birthday. Coffee-houses became a popular place to debate ideas, as growing literacy and development of the printing press made news widely available, with Fleet Street becoming

7068-430: The Admiralty the use of the flying field and Frank McClean had agreed to act as an instructor, so beginning a close association between Short Brothers and the Naval Air Service, whose first pilots were trained using Short S.27 pusher biplanes. In 1911, Shorts built one of the world's first successful twin-engine aircraft, the Triple Twin . Construction started on a long series of naval aircraft floatplanes, starting with

The area of Greater London includes areas that are part of the historic counties of Middlesex , Kent , Surrey , Essex and Hertfordshire . More recently, Greater London has been defined as a region of England and in this context

7316-482: The Empire, the S.26 G-Class was developed, but only three completed before the war resulted in further production being cancelled. Short's work on the Sunderland also won it the contract for the Short Stirling four-engine bomber-transport for the RAF. This was essentially a land-based Sunderland, however its use of a now outdated thick-section, low aspect ratio wing to facilitate it going into service quickly limited climb and ceiling, and design decisions, such as

7440-435: The London area. This called for the Corporation of the city to extend its jurisdiction and administration over expanding areas around the city.

7564-453: The S.184 was also sold to the Royal Flying Corps as the Short Bomber . During the First World War, Shorts were among the manufacturers of two flying boats, the F.3 and F.5 , designed by John Porte at the Seaplane Experimental Station , Felixstowe. When the war ended, some 50 of these were being built at Rochester. Due to the company's success, and the increasing number of seaplanes being produced, larger premises with ready access to

7688-590: The Second World War, the airfield was requisitioned by the Royal Navy. Shorts continued to use the airfield until production of complete aircraft ceased, despite Nutts Corner , a former RAF base, becoming Belfast's main airport (Nutts Corner was itself superseded in 1963 by Aldergrove ). In 1983, following interest from airlines and customers, the airfield was opened for commercial flights as Belfast Harbour Airport (later Belfast City Airport (BCA), now George Best Belfast City Airport ). Following major capital investment, Bombardier sold BCA for £35 million in 2003. In 1977,

7812-423: The Short S.26. In 1913, Gordon Bell became Shorts' first professional test pilot: he was succeeded by Ronald Kemp in 1914. Kemp could not handle the volume of flight testing and development alone and, by 1916, other pilots were employed on a freelance basis. One of these was John Lankester Parker . In 1918 Parker succeeded Kemp as Shorts' Chief Test Pilot , a post he was to occupy for the next 27 years. In 2013

7936-419: The Skyvan proved more popular in the freighter market due to the large rear cargo door that allowed it to handle bulky loads with ease. Skyvans can still be found around the world today. The heavy lift freighter Short SC.5 Belfast flew for the first time in 1964. Only 10 were built for the Royal Air Force . In the 1970s, Shorts entered the feederliner market with the Shorts 330 , a stretched modification of

In 1988, the proposed development was announced of a regional jet seating 44 passengers and to be called the FJX. The aircraft would have been a competitor to the Bombardier CRJ100 that was also in development at

8184-409: The Thames. Despite the evidence of scattered Brythonic settlements in the area, the first major settlement was founded by the Romans around 47 AD, about four years after their invasion of 43 AD. This only lasted until about 61 AD, when the Iceni tribe led by Queen Boudica stormed it and burnt it to the ground. The next planned incarnation of Londinium prospered, superseding Colchester as

8308-415: The United Kingdom's population and over 16% of England's population. The Greater London Built-up Area is the fourth-most populous in Europe, with about 9.8 million inhabitants as of 2011. The London metropolitan area is the third-most populous in Europe, with about 14 million inhabitants as of 2016, making London a megacity . Four World Heritage Sites are located in London: Kew Gardens ;

8432-423: The United Kingdom. Shorts survived without reducing the company's workforce by diversifying into areas such as building lightweight bus and tram bodies. During the 1920s and 1930s, flying boats were favoured for long-range civil aviation, because their operation did not rely on the existence of suitable airfields, which were not widespread at the time. Shorts took to the flying boat market, and in 1924 constructed

8556-405: The Viking incursions formally agreed by the Danish warlord , Guthrum and the West Saxon king Alfred the Great in 886. The Anglo-Saxon Chronicle records that Alfred "refounded" London in 886. Archaeological research shows this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls . London then grew slowly until a dramatic increase in about 950. By

8680-412: The balloons at Hove, Sussex , in premises above the acoustic laboratory run by a third brother, Horace (2 July 1872 – 6 April 1917). In 1903, when Horace left to work on steam turbine development with Charles Parsons , Eustace and Oswald moved their workshop to rented accommodation in London, then again to railway arches in Battersea , conveniently situated next to Battersea gas-works. In 1905, they won

8804-441: The brothers had obtained the British rights to build copies of the Wright design . In February 1909, Shorts started construction of a new workshop on unobstructed marshland at Leysdown, near Shellbeach on the Isle of Sheppey . This had been acquired by the Aero Club for use as a flying ground, together with Mussell Manor (now known as "Muswell Manor"), which became its clubhouse. Construction of an initial batch of six aircraft

8928-559: The centre of the British press. The invasion of Amsterdam by Napoleonic armies led many financiers to relocate to London and the first London international issue was arranged in 1817. Around the same time, the Royal Navy became the world's leading war fleet, acting as a major deterrent to potential economic adversaries. Following a fire in 1838, the Royal Exchange was redesigned by William Tite and rebuilt in 1844. The repeal of

9052-536: The city's metropolis. The City of London at its core once comprised the whole settlement, but as its urban area grew, the Corporation of London resisted attempts to amalgamate the city with its suburbs , causing "London" to be defined several ways. Forty per cent of Greater London is covered by the London post town , in which 'London' forms part of postal addresses. The London telephone area code (020) covers

9176-412: The city, to intimidate the inhabitants. In 1097, William II began building Westminster Hall , near the abbey. It became the basis of a new Palace of Westminster . In the 12th century, the institutions of central government, which had hitherto followed the royal English court around the country, grew in size and sophistication and became increasingly fixed, for most purposes at Westminster , although

9300-600: The combined revenue expenditure by London councils and the GLA amounted to just over £22 billion (£14.7 billion for the boroughs and £7.4 billion for the GLA). The London Fire Brigade is the statutory fire and rescue service for Greater London, run by the London Fire and Emergency Planning Authority . It is the third largest fire service in the world. National Health Service ambulance services are provided by

9424-440: The company changed its name back to Short Brothers, and in 1984 it became a public limited company in preparation for privatisation. The government announced the sale of Shorts to Bombardier on 7 June 1989 for £30 million. As part of the sale, the government agreed (at the insistence of then-Chancellor John Major ) to write off £390 million of the company's "accumulated losses and inject another £390 million to recapitalise

9548-483: The company near Cardington to house its employees still bears the name Shortstown . In 1919, the name of the company was changed to Short Brothers (Rochester and Bedford) Ltd., but nationalisation the same year ended the Short brothers' involvement with the company, which became the Royal Airship Works . During the immediate post-war years the economic climate was difficult for the aircraft industry in

9672-407: The company was producing. The Eastchurch premises was closed in 1934, and in the same year Shorts purchased the engine manufacturer Pobjoy , which had moved to Rochester Airport to be near Shorts and had collaborated on its latest designs. On 5 July 1937, a Short Empire was used by Imperial Airways for the first westbound transatlantic service from Foynes , Ireland to Newfoundland . In 1936,

9796-526: The continued production there of Britannias. In the 1960s, Shorts found a niche for a new short-haul freighter aircraft and responded with the Short SC.7 Skyvan . The Skyvan is most remembered for its box-like, slab-sided appearance and rectangular twin tail units, but the aircraft was well loved for its performance and loading. It served almost the same performance niche as the de Havilland Twin Otter , and

9920-626: The creation of the Greater London Authority . To mark the 21st century, the Millennium Dome , London Eye and Millennium Bridge were constructed. On 6 July 2005 London was awarded the 2012 Summer Olympics , as the first city to stage the Olympic Games three times. On 7 July 2005, three London Underground trains and a double-decker bus were bombed in a series of terrorist attacks . In 2008, Time named London alongside New York City and Hong Kong as Nylonkong , hailing them as

10044-559: The creation of the London Underground , the world's first urban rail network . The Metropolitan Board of Works oversaw infrastructure expansion in the capital and some surrounding counties; it was abolished in 1889 when the London County Council was created out of county areas surrounding the capital. From the early years of the 20th century onwards, teashops were found on High Streets across London and

10168-552: The design and development of very short-range, air defence missiles for the UK Ministry of Defence and armed forces worldwide using expertise dating back to the 1950s. In 2000, Thomson-CSF bought Bombardier's 50% share to become the sole owner of Shorts Missile Systems, renaming it Thales Air Defence in 2001. On 31 October 2019, Bombardier announced the sale of its aerostructures activities to Spirit AeroSystems . The sale closed in November 2020 following regulatory approval and

10292-713: The driest is 1921, with a total fall of 12.1 inches (308 mm). The average annual precipitation amounts to about 600mm, which is half the annual rainfall of New York City . Despite relatively low annual precipitation, London receives 109.6 rainy days on the 1.0mm threshold annually. London is vulnerable to climate change , and there is concern among hydrological experts that households may run out of water before 2050. Temperature extremes in London range from 40.2 °C (104.4 °F) at Heathrow on 19 July 2022 down to −17.4 °C (0.7 °F) at Northolt on 13 December 1981. Records for atmospheric pressure have been kept at London since 1692. The highest pressure ever reported

10416-722: The earlier Boeing 777, which will provide an extra 7 metres (23 ft) of total wingspan in flight, while allowing the airplane to fit inside the same airport gates as the 777-200LR/777-300ER. Aircraft with ventral fins under the fuselage for stability which had to be folded for takeoff and landing include the Mikoyan-Gurevich MiG-23 , the MiG-27 , and the Vought XF8U-3 Crusader III . An example of aircraft using folding wingtips other than stowage/hangar space such as aerodynamics and flight handling

10540-609: The first Muslim mayor of a major Western capital. The mayor's statutory planning strategy is published as the London Plan , which was most recently revised in 2011. The local authorities are the councils of the 32 London boroughs and the City of London Corporation . They are responsible for most local services, such as local planning, schools, libraries, leisure and recreation, social services , local roads and refuse collection. Certain functions, such as waste management , are provided through joint arrangements. In 2009–2010

10664-524: The first of those made its maiden flight. Of these types, Shorts delivered 60 Canberra B.2s, 49 Canberra B.6s and 23 Canberra P.R.9s, the remaining 18 being cancelled by the Government in 1957. Further work was involved in the conversion of time-expired Canberra B.2s into unmanned radio-controlled missile target aircraft. Two prototypes and 10 production Canberra U.10s were produced, followed by six improved Canberra U.14s. These aircraft were controlled from

10788-768: The first was flown in June 1928; both were delivered to Western Canada Airlines Ltd. In 1924, Shorts produced the first of a series of three designs known as the Singapore . In 1927, the Singapore I was used by Sir Alan Cobham, when he, his wife, and crew made a survey of Africa which covered about 23,000 miles. Shorts then started design work on the Short Calcutta , based on the Singapore layout but larger and more powerful, which began service with Imperial Airways in August 1928. By April 1929 two more had been added to

10912-497: The fleet, and they operated passenger-preferred coastal routes from Genoa to Alexandria by way of Athens , Corfu , Naples , and Rome . Several Calcuttas were used on shorter routes, and were instrumental in permitting long-range airline services between outposts of the British Empire . Shorts followed the production of four Calcuttas with the larger Kent , following with a series of still larger aircraft designs such as

11036-542: The ground by VHF radio, and were equipped to provide feedback on their own performance, as well as that of the missiles aimed at them. As early as 1953, Shorts became involved with pioneering the development of electronic analogue computers , to assist with the design of increasingly complex aircraft. In 1954, the Bristol Aeroplane Company became a 15.25% shareholder in Shorts, and the company used

11160-435: The group and cover current and future losses, capital investment and training." Bombardier beat a bid from General Electric Company and Fokker . Messerschmitt-Bölkow-Blohm had withdrawn before final offers were submitted. The sale was finalised on 4 October 1989. In 1993, with the company under the chairmanship of Sir Roy McNulty , Bombardier Shorts and Thomson-CSF formed a joint venture, Shorts Missile Systems , for

11284-697: The highest-ranked academic institutions in the world: Imperial College London in natural and applied sciences , the London School of Economics in social sciences , and the comprehensive University College London . It is the most visited city in Europe and has the world's busiest city airport system . The London Underground is the world's oldest rapid transit system. London's diverse cultures encompass over 300 languages. The 2023 population of Greater London of just under 10 million made it Europe's third-most populous city , accounting for 13.4% of

11408-478: The injection of funds to set up a production line for the Bristol Britannia turbo-prop airliner, known in the press as The Whispering Giant . Although it was originally intended that 35 Britannias should be built by Shorts, a shortage of work at Bristol led to this number being reduced. Eventually, 15 Britannias were completed by Shorts; five sets of Britannia components were sent to Filton and used on

11532-640: The location of its original headquarters in a road called Great Scotland Yard in Whitehall. The City of London has its own police force – the City of London Police . First worn by Met police officers in 1863, the custodian helmet has been called a "cultural icon" and a "symbol of British law enforcement". Introduced by the Met in 1929, the blue police telephone box (basis for the TARDIS in Doctor Who )

11656-409: The mayor's budget proposals each year. The GLA has responsibility for the majority of London's transport system through its functional arm Transport for London (TfL), it is responsible for overseeing the city's police and fire services, and also for setting a strategic vision for London on a range of issues. The headquarters of the GLA is City Hall , Newham. The mayor since 2016 has been Sadiq Khan ,

11780-705: The most museums , art galleries, libraries, and cultural venues in the UK, including the British Museum , National Gallery , Natural History Museum , Tate Modern , British Library , and numerous West End theatres. Important sporting events held in London include the FA Cup Final , the Wimbledon Tennis Championships , and the London Marathon . It became the first city to host three Summer Olympic Games upon hosting

11904-675: The most diverse cities in the world. In 1951, the Festival of Britain was held on the South Bank . The Great Smog of 1952 led to the Clean Air Act 1956 , which ended the " pea soup fogs " for which London had been notorious, and had earned it the nickname the "Big Smoke". Starting mainly in the mid-1960s, London became a centre for worldwide youth culture , exemplified by the Swinging London sub-culture associated with

12028-467: The old Roman city. By about 680 the city had become a major port again, but there is little evidence of large-scale production. From the 820s repeated Viking assaults brought decline. Three are recorded; those in 851 and 886 succeeded, while the last, in 994, was rebuffed. The Vikings applied Danelaw over much of eastern and northern England, its boundary running roughly from London to Chester as an area of political and geographical control imposed by

12152-658: The planning and construction work started. By early 1915, the first facility of what was to become known as the Seaplane Works was completed: No.1 Erecting Shop. As this and the No.2 and No.3 shops became available, the workforce moved from the Eastchurch factory. No.3 shop was completed in 1917. A long concrete slipway was constructed from the centre-line of No.3 Erecting Shop to enable aircraft of up to 20 tons weight to be launched even at low tide. In 1916, Short Brothers

12276-490: The principal city of the Roman province of Britannia in 100. At its height in the 2nd century, Roman London had a population of about 60,000. With the early 5th-century collapse of Roman rule, the walled city of Londinium was effectively abandoned, although Roman civilisation continued around St Martin-in-the-Fields until about 450. From about 500, an Anglo-Saxon settlement known as Lundenwic developed slightly west of

12400-465: The resources, and it was rapidly developing the dignity and the political self-consciousness appropriate to a national capital ." After winning the Battle of Hastings , William, Duke of Normandy was crowned King of England in newly completed Westminster Abbey on Christmas Day 1066. William built the Tower of London , the first of many such in England rebuilt in stone in the south-eastern corner of

12524-641: The rest of Britain, with Lyons , who opened the first of their chain of teashops in Piccadilly in 1894, leading the way. The tearooms, such as the Criterion in Piccadilly, became a popular meeting place for women from the suffrage movement. The city was the target of many attacks during the suffragette bombing and arson campaign , between 1912 and 1914, which saw historic landmarks such as Westminster Abbey and St Paul's Cathedral bombed. London

12648-401: The royal treasury came to rest in the Tower . While the City of Westminster developed into a true governmental capital, its distinct neighbour, the City of London , remained England's largest city and principal commercial centre and flourished under its own unique administration, the Corporation of London . In 1100, its population was some 18,000; by 1300 it had grown to nearly 100,000. With

12772-457: The sea were needed. At that time, seaplanes were taken by road to Queenborough, then loaded onto lighters to be taken to the RNAS seaplane station on Isle of Grain to be launched and tested. In 1913, an 8.4 acre (3.4 hectare) plot of land by the river Medway about 20 miles (32 km) away at Borstal , near Rochester, Kent , was purchased from Charles Willis (a local councillor ), and

12896-546: The sea. London is the seat of the Government of the United Kingdom . Many government departments, as well as the prime minister's residence at 10 Downing Street , are based close to the Palace of Westminster , particularly along Whitehall . There are 75 members of Parliament (MPs) from London; As of June 2024 , 59 are from the Labour Party , 9 are Conservatives , 6 are Liberal Democrats and one constituency

13020-424: The start of 2018 to mid April 2018. Funding cuts to police in London are likely to have contributed to this, though other factors are involved. However, homicide figures fell in 2022 with 109 recorded for the year, and the murder rate in London is much lower than other major cities around the world. London, also known as Greater London , is one of nine regions of England and the top subdivision covering most of

13144-497: The stillborn wartime Seaford , which was to have been the penultimate Sunderland development. In 1943, the Government nationalised Short's under Defence Regulation 78. Oswald Short, who had resigned as Chairman in January of that year, remained as Honorary Life President. By 1947, all of Shorts other wartime factories had been closed, and operations concentrated in Belfast. In 1948, the company offices followed, and Shorts became

13268-753: The theatres in the 1640s. The ban on theatre was lifted during the Restoration in 1660, and London's oldest operating theatre, Drury Lane , opened in 1663 in what is now the West End theatre district. By the end of the Tudor period in 1603, London was still compact. There was an assassination attempt on James I in Westminster, in the Gunpowder Plot of 5 November 1605. In 1637, the government of Charles I attempted to reform administration in

13392-442: The time . Since the 19th century, the name "London" has referred to the metropolis around the City of London, historically split between the counties of Middlesex , Essex , Surrey , Kent , and Hertfordshire , which since 1965 has largely comprised the administrative area of Greater London , governed by 33 local authorities and the Greater London Authority . As one of the world's major global cities , London exerts

13516-812: The time, but the FJX was cancelled after Short Brothers' sale to Bombardier. In 1987 loyalists working at Shorts erected loyalist flags and bunting to intimidate the Catholic workers. The loyalist workers went on strike after management removed the loyalist flags from the shop floor. In April 1989, three Northern Irish men, Noel Little , Samuel Quinn and James King, were arrested in Paris and later convicted of "arms trafficking and associating with criminals involved in terrorist activities." They were accused of having stolen missile parts and documents related to Shorts' products. Also arrested were arms dealer Douglas Bernhardt and

13640-715: The unique governmental status of the City . In the English Civil War , the majority of Londoners supported the Parliamentary cause. After an initial advance by the Royalists in 1642, culminating in the battles of Brentford and Turnham Green , London was surrounded by a defensive perimeter wall known as the Lines of Communication . The lines were built by up to 20,000 people, and were completed in under two months. The fortifications failed their only test when

13764-537: The use of cells for individual bombs limited its long term usefulness as a heavy bomber when it proved incapable of carrying the newer larger bombs that didn't fit in the cells. As it was intended as a stopgap pending the delivery of the Handley Page Halifax and Avro Manchester bombers, it followed the RAF tradition of also being a transport aircraft, with a cabin useful for troops and cargo, in which role it

13888-639: The world's three most influential global cities . In January 2015, Greater London's population was estimated to be 8.63 million, its highest since 1939. During the Brexit referendum in 2016, the UK as a whole decided to leave the European Union , but most London constituencies voted for remaining. However, Britain's exit from the EU in early 2020 only marginally weakened London's position as an international financial centre. The administration of London

14012-968: Was bombed by the Germans in the First World War , and during the Second World War , the Blitz and other bombings by the German Luftwaffe killed over 30,000 Londoners, destroying large tracts of housing and other buildings across the city. The tomb of the Unknown Warrior , an unidentified member of the British armed forces killed during the First World War, was buried in Westminster Abbey on 11 November 1920. The Cenotaph , located in Whitehall ,

14136-572: Was abandoned shortly after the end of the war, however conversions and developments of the Sunderland entered service as transports, starting during the war with the Hythe , which was a demilitarized Sunderland with the turrets faired over, then the post-war Sandringham , which refined the shape to eliminate the turret mountings, and finally by the definitive Solent , with an enlarged tail and more powerful engines and other refinements derived from

14260-559: Was awarded a contract to build two large dirigible airships for the Admiralty . As part of the contract, a loan was provided to enable the company to purchase a site near Cardington, Bedfordshire , on which to build airship construction facilities. As a result, the company concentrated on the construction of heavier-than-air aeroplanes in the Isle of Sheppey/Rochester area, and balloons and dirigibles at Cardington. A housing estate built by

14384-584: Was established at White Cross Bay, Windermere , that produced 35 Sunderland Mark IIIs. Austin Motors at Longbridge, Birmingham also produced over 600 Stirlings , and Blackburn Aircraft produced 240 Sunderlands at its shadow factory in Dumbarton, Scotland. During the Second World War , the Short Sunderland was an effective anti-submarine patrol bomber operated by RAF Coastal Command in

14508-437: Was once a common sight throughout London and regional cities in the UK. The British Transport Police are responsible for police services on National Rail , London Underground , Docklands Light Railway and Tramlink services. The Ministry of Defence Police is a special police force in London, which does not generally become involved with policing the general public. The UK's domestic counter-intelligence service ( MI5 )

14632-547: Was particularly notable for its flying boat designs manufactured into the 1950s. In 1943, Shorts was nationalised and later denationalised, and in 1948 moved from its main base at Rochester, Kent to Belfast. In the 1960s, Shorts mainly produced turboprop airliners, major components for aerospace primary manufacturers, and missiles for the British Armed Forces . Shorts was primarily government -owned until being bought by Bombardier in 1989 and, in 2007,

14756-544: Was started immediately. Short Brothers thus became the first aircraft manufacturing company in the world to undertake volume production of an aircraft design. Here the Dunne D.5 , the first tailless aircraft , was also built under contract. In 1910 the Royal Aero Club and Short Brothers moved to a larger and less marshy ground at Eastchurch , about 2.5 miles (4 km) away. At this time the Royal Aero Club had offered

14880-465: Was supervised by polymath Robert Hooke . In 1710, Christopher Wren 's masterpiece, St Paul's Cathedral , was completed, replacing its medieval predecessor that burned in the Great Fire of 1666. The dome of St Paul's dominated the London skyline for centuries, inspiring the artworks and writing of William Blake , with his 1789 poem " Holy Thursday " referring to 'the high dome of Pauls'. During

15004-542: Was the North American XB-70 Valkyrie . This increased both compression lift and enhanced directional stability at high speeds. Short Brothers Short Brothers plc , usually referred to as Shorts or Short , is an aerospace company based in Belfast , Northern Ireland . Shorts was founded in 1908 in London , and was the first company in the world to make production aeroplanes. It

15128-450: Was the largest manufacturing concern in Northern Ireland. In November 2020, Bombardier sold its Belfast operations to Spirit AeroSystems . The company's products include aircraft components, engine nacelles and aircraft flight control systems for Bombardier Aerospace , Boeing , Rolls-Royce Deutschland , General Electric and Pratt & Whitney . The Short Brothers business started in 1897 when Eustace Short (1875 – 1932) bought

15252-524: Was unveiled on the same day, and is the focal point for the National Service of Remembrance held annually on Remembrance Sunday , the closest Sunday to 11 November. The 1948 Summer Olympics were held at the original Wembley Stadium , while London was still recovering from the war. From the 1940s, London became home to many immigrants, primarily from Commonwealth countries such as Jamaica, India, Bangladesh and Pakistan, making London one of

15376-523: Was used once the Halifax and Avro Lancaster were available in large enough numbers. Attempts by Shorts to sell improved versions to the RAF were ignored, not least over concerns regarding Oswald's leadership and alcoholism. In 1944, the Short Shetland , a high-speed, long-range, four-engined flying-boat, was built (with Saunders-Roe providing the wings and detail design work), but the project
