Norwalk is a U. S. city located in southwestern Connecticut, in southern Fairfield County, on the northern shore of Long Island Sound. Norwalk lies within both the New York metropolitan area as well as the Bridgeport metropolitan area. Norwalk was settled in 1649, is the sixth most populous city in Connecticut. According to the 2010 United States Census it has had a population of 85,603. Norwalk was settled in 1649, incorporated September 1651, named after the Algonquin word noyank, meaning "point of land", or more from the native American name "Naramauke."The Battle of Norwalk took place during the Revolutionary War, lead to the burning of most of the town. In 1836, the borough of Norwalk was created. In 1853, the first train disaster in the United States happened over the Norwalk River. During the 19th and early 20th century, Norwalk was a major railroad stop for the New York, New Haven, Hartford Railroad; the city of South Norwalk and the remaining parts of the town of Norwalk were both combined in 1910 to form the current city.
The Ku Klux Klan had a brief presence in Norwalk during the 1920s, but fell apart due to internal issues. In 1955, multiple hurricanes hit thje city. During the 1970s, efforts were taken to preserve South Norwalk, resulting in the creation of the Washington Street Historic District. According to the United States Census Bureau, the city has a total area of 36.3 square miles, of which, 22.8 square miles of it is land and 13.5 square miles of it is water. Norwalk's topography is dominated by its coastline along Long Island Sound, the Norwalk River and its eastern and western banks, the Norwalk Islands; the highest elevation is 282 feet above sea level, at the summit of Middle Clapboard Hill in West Norwalk. As of the census of 2010, there were 85,603 people, 35,415 households, 21,630 families residing in the city; the population density was 2,358.2 inhabitants per square mile. There were 35,415 housing units at an average density of 975.6 per square mile. The racial makeup of the city was 68.7% White, 14.2% African American, 0.4% Native American, 4.8% Asian, 0.1% Pacific Islander, 9.0% from other races, 2.8% from two or more races.
Hispanic or Latino of any race were 24.3% of the population. There were 35,415 households out of which 27.9% had children under the age of 18 living with them, 47.1% were married couples living together, 11.0% had a female householder with no husband present, 38.4% were non-families. 33.0% of all households were made up of individuals and 8.5% had someone living alone, 65 years of age or older. The average household size in the city was 2.55 and the average family size was 3.16. The population's spread gives 22% under the age of 18, with 7.3% from 18 to 24, 31.7% from 25 to 44, 31.2% from 45 to 64, 12.8% aged 65 years or older. The median age is 40 years. For every 100 females, there are 96.2 males. The median income for a household in the city was $76,161, the median income for a family was $103,032; the per capita income for the city was $43,303. About 5.7% of families and 8.4% of the population were below the poverty line, including 10.2% of those under age 18 and 8.2% of those age 65 or over.
Pepperidge Farm, Frontier Communications, Booking Holdings have headquarters in Norwalk. St. George Greek Orthodox Festival, held in late August, the festival features Greek delicacies, Pontic Greek dance exhibitions and a large carnival. Round Hill Highland Games: a festival of Scottish culture and athletic events, was started in 1923 in Greenwich, CT but interrupted during World War II restarted in 1952, has been held in Norwalk's Cranbury Park on or around July 4 for a number of years. In 2006, the 83rd annual event attracted 4,000 people to hear bagpipes and watch the caber toss, the hammer throw, other events. Games for children are offered. Food and Scottish items are offered for sale. Organizers say. Beth Israel Synagogue AKA Canaan Institutional Baptist Church Saint Jerome Church Saint Joseph Church Saint Ladislaus Church Saint Mary Church Saint Matthew Church St. Philip Church Saint Thomas the Apostle ChurchTemple Shalom Temple Beth- El The City of Norwalk has six taxing districts; the First, Second and Sixth taxing districts are political entities with their respective voters electing officers, holding annual business meetings, approving budgets and to consider other matters, as specified in each of their charters.
Election of Taxing District Commissioners and Treasurers by voters from the 1st, 2nd, 3rd, 6th districts take place in odd numbered years. The Fourth and Fifth districts are not counted as separate governments as they constitute the city proper; each taxing district has its own property tax rate reflecting the mix of services each receives from the city. Secondly, municipal elections of Mayor, Common Council, Board of Education and other positions are held in odd numbered years at thirteen polling places within five voting districts around the city. Voting districts are not the same for state and federal elections which are held on numbered years at twelve polling locations Norwalk's municipal government is a Weak-mayor form of a Mayor-Council government with the mayor of Norwalk elected by its voters; the city's charter gives certain administrative powers to the Council and others jointly to the Council and Mayor.

A car is a wheeled motor vehicle used for transportation. Most definitions of car say they run on roads, seat one to eight people, have four tires, transport people rather than goods. Cars came into global use during the 20th century, developed economies depend on them; the year 1886 is regarded as the birth year of the modern car when German inventor Karl Benz patented his Benz Patent-Motorwagen. Cars became available in the early 20th century. One of the first cars accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were adopted in the US, where they replaced animal-drawn carriages and carts, but took much longer to be accepted in Western Europe and other parts of the world. Cars have controls for driving, passenger comfort, safety, controlling a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex; these include rear reversing cameras, air conditioning, navigation systems, in-car entertainment.
Most cars in use in the 2010s are propelled by an internal combustion engine, fueled by the combustion of fossil fuels. Electric cars, which were invented early in the history of the car, began to become commercially available in 2008. There are benefits to car use; the costs include acquiring the vehicle, interest payments and maintenance, depreciation, driving time, parking fees and insurance. The costs to society include maintaining roads, land use, road congestion, air pollution, public health, health care, disposing of the vehicle at the end of its life. Road traffic accidents are the largest cause of injury-related deaths worldwide; the benefits include on-demand transportation, mobility and convenience. The societal benefits include economic benefits, such as job and wealth creation from the automotive industry, transportation provision, societal well-being from leisure and travel opportunities, revenue generation from the taxes. People's ability to move flexibly from place to place has far-reaching implications for the nature of societies.
There are around 1 billion cars in use worldwide. The numbers are increasing especially in China and other newly industrialized countries; the word car is believed to originate from the Latin word carrus or carrum, or the Middle English word carre. In turn, these originated from the Gaulish word karros, it referred to any wheeled horse-drawn vehicle, such as a cart, carriage, or wagon. "Motor car" is attested from 1895, is the usual formal name for cars in British English. "Autocar" is a variant, attested from 1895, but, now considered archaic. It means "self-propelled car"; the term "horseless carriage" was used by some to refer to the first cars at the time that they were being built, is attested from 1895. The word "automobile" is a classical compound derived from the Ancient Greek word autós, meaning "self", the Latin word mobilis, meaning "movable", it entered the English language from French, was first adopted by the Automobile Club of Great Britain in 1897. Over time, the word "automobile" fell out of favour in Britain, was replaced by "motor car".
"Automobile" remains chiefly North American as a formal or commercial term. An abbreviated form, "auto", was a common way to refer to cars in English, but is now considered old-fashioned; the word is still common as an adjective in American English in compound formations like "auto industry" and "auto mechanic". In Dutch and German, two languages related to English, the abbreviated form "auto" / "Auto", as well as the formal full version "automobiel" / "Automobil" are still used — in either the short form is the most regular word for "car"; the first working steam-powered vehicle was designed — and quite built — by Ferdinand Verbiest, a Flemish member of a Jesuit mission in China around 1672. It was a 65-cm-long scale-model toy for the Chinese Emperor, unable to carry a driver or a passenger, it is not known with certainty if Verbiest's model was built or run. Nicolas-Joseph Cugnot is credited with building the first full-scale, self-propelled mechanical vehicle or car in about 1769, he constructed two steam tractors for the French Army, one of, preserved in the French National Conservatory of Arts and Crafts.
His inventions were, handicapped by problems with water supply and maintaining steam pressure. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam-powered road vehicle, it was unable to maintain sufficient steam pressure for long periods and was of little practical use. The development of external combustion engines is detailed as part of the history of the car but treated separately from the development of true cars. A variety of steam-powered road vehicles were used during the first part of the 19th century, including steam cars, steam buses and steam rollers. Sentiment against them led to the Locomotive Acts of 1865. In 1807, Nicéphore Niépce and his brother Claude created what was the world's first internal combustion engine, but they chose to install it in a boat on the river Saone in France. Coincidentally, in 1807 the Swiss inventor François Isaac de Rivaz designed his own'de Rivaz internal combustion engine' and used it to develop the world's first vehicle to be powered by such an engine.
Canadian General Electric
Canadian General Electric was a Canadian manufacturer of various electrical products. The company was a forerunner of General Electric Canada, now known as GE Canada, it was the Canadian counterpart of the American company General Electric. The unit became General Electric Canada in 1989. Canadian General Electric Co. Limited was incorporated in Canada in 1892 as a merger of Edison Electric Light Company of Canada and Thomson-Houston Electric Light Company of Canada, both incorporated in Canada in 1882; the Canadian merger occurred in the same year as the merger of parent companies Edison General Electric and Thomson-Houston Company into General Electric, which continues to the present day as a major international conglomerate. CGE had about 500 employees at inception and was producing generators, motors and cable, lighting products for consumer and industrial products. CGE had a long manufacturing history in Canada: 1892 - Founded and opens engine/motor plant is Peterborough, Ontario 1899 - Produces the Canadian General Electric electric car, for model year 1899 only, in Peterborough, Ontario.
The car is a Woods Electric. 1911 - Acquires Sunbeam Lamp Company of Toronto. 1912 - Establishes Montreal lamp plant. 1921 - Vacuum tube operations begin in Toronto. 1922 - Canadian Edison Appliance Company established. 1945 - Small appliances plant opens in Barrie, Ontario. 1946 - Plastics plant opens in Cobourg, Ontario. 1946 - Lighting plant opens in Oakville, Ontario. 1947 - Electric meter plant opens in Quebec City. 1971 - The Karachi Nuclear Power Plant, built by CGE, opens 1975 - Household appliance division spun off and merged with GSW Inc. a Canadian manufacturer of household appliances with brands such as McClary and Moffat, in a new company named Camco. Camco is a part of the General Electric family of companies. 1989 - CGE becomes General Electric Canada, a wholly owned unit of General Electric. 1990s - Electric lamp operations in the Oakville, Ontario factory begins to get transferred to Warren, OH and Winchester, VA lamp plants. Most fluorescent tube operations are ceased by the late 1990s.
2009 - Most incandescent lamp production lines in the Oakville, ON plant are stopped. Production is transferred to Winchester, VA. 2010 - Oakville, ON lamp plant closes. Remaining incandescent lamp operations are transferred to China. A few products are outsourced from Sylvania's US plants. T8 fluorescent tube operations go to Bucyrus, OH. 2018 - Planned Peterborough plant shutdown 2018 - Planned reciprocating gas engine plant opening in Welland, Ontario to replace an existing factory in Waukesha, Wisconsin. The reason for moving to Canada from the U. S. is a lack of export financing from the U. S. Export-Import Bank
General Electric Company is an American multinational conglomerate incorporated in New York and headquartered in Boston. As of 2018, the company operates through the following segments: aviation, power, renewable energy, digital industry, additive manufacturing, venture capital and finance and oil and gas. In 2018, GE ranked among the Fortune 500 as the 18th-largest firm in the U. S. by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th-most profitable company but has since severely underperformed the market as its profitability collapsed. Two employees of GE—Irving Langmuir and Ivar Giaever —have been awarded the Nobel Prize. During 1889, Thomas Edison had business interests in many electricity-related companies including Edison Lamp Company, a lamp manufacturer in East Newark, New Jersey. P. Morgan and the Vanderbilt family for Edison's lighting experiments. In 1889, Morgan & Co. a company founded by J. P. Morgan and Anthony J. Drexel, financed Edison's research and helped merge those companies under one corporation to form Edison General Electric Company, incorporated in New York on April 24, 1889.
The new company acquired Sprague Electric Railway & Motor Company in the same year. In 1880, Gerald Waldo Hart formed the American Electric Company of New Britain, which merged a few years with Thomson-Houston Electric Company, led by Charles Coffin. In 1887, Hart left to become superintendent of the Edison Electric Company of Missouri. General Electric was formed through the 1892 merger of Edison General Electric Company of Schenectady, New York, Thomson-Houston Electric Company of Lynn, with the support of Drexel, Morgan & Co. Both plants continue to operate under the GE banner to this day; the company was incorporated in New York, with the Schenectady plant used as headquarters for many years thereafter. Around the same time, General Electric's Canadian counterpart, Canadian General Electric, was formed. In 1896, General Electric was one of the original 12 companies listed on the newly formed Dow Jones Industrial Average, where it remained a part of the index for 122 years, though not continuously.
In 1911, General Electric absorbed the National Electric Lamp Association into its lighting business. GE established its lighting division headquarters at Nela Park in Ohio; the lighting division has since remained in the same location. Owen D. Young, through GE, founded the Radio Corporation of America in 1919, after purchasing the Marconi Wireless Telegraph Company of America, he aimed to expand international radio communications. GE used RCA as its retail arm for radio sales. In 1926, RCA co-founded the National Broadcasting Company, which built two radio broadcasting networks. In 1930, General Electric was charged with antitrust violations and decided to divest itself of RCA. In 1927, Ernst Alexanderson of GE made the first demonstration of his television broadcasts at his General Electric Realty Plot home at 1132 Adams Rd, New York. On January 13, 1928, he made what was said to be the first broadcast to the public in the United States on GE's W2XAD: the pictures were picked up on 1.5 square inch screens in the homes of four GE executives.
The sound was broadcast on GE's WGY. Experimental television station W2XAD evolved into station WRGB which, along with WGY and WGFM, was owned and operated by General Electric until 1983. Led by Sanford Alexander Moss, GE moved into the new field of aircraft turbo superchargers. GE introduced the first set of superchargers during World War I, continued to develop them during the interwar period. Superchargers became indispensable in the years prior to World War II. GE supplied 300,000 turbo superchargers for use in bomber engines; this work led the U. S. Army Air Corps to select GE to develop the nation's first jet engine during the war; this experience, in turn, made GE a natural selection to develop the Whittle W.1 jet engine, demonstrated in the United States in 1941. GE was ranked ninth among United States corporations in the value of wartime production contracts. Although, their early work with Whittle's designs was handed to Allison Engine Company. GE Aviation emerged as one of the world's largest engine manufacturers, bypassing the British company, Rolls-Royce plc.
Some consumers boycotted GE light bulbs and other products during the 1980s and 1990s. The purpose of the boycott was to protest against GE's role in nuclear weapons production. In 2002, GE acquired the wind power assets of Enron during its bankruptcy proceedings. Enron Wind was the only surviving U. S. manufacturer of large wind turbines at the time, GE increased engineering and supplies for the Wind Division and doubled the annual sales to $1.2 billion in 2003. It acquired ScanWind in 2009. In 2015, GE Power garnered press attention when a model 9FB gas turbine in Texas was shut down for two months due to the break of a turbine blade; this model uses similar blade technology to GE's newest and most efficient model, the 9HA. After the break, GE developed heat treatment methods. Gas turbines represent a significant portion of GE Power's revenue, represent a significant portion of the power generation fleet of several utility companies in the United States. Chubu Electric of Japan and Électricité de France had units that were impacted.
Health care or healthcare is the maintenance or improvement of health via the prevention and treatment of disease, illness and other physical and mental impairments in people. Health care is delivered by health professionals in allied health fields. Physicians and physician associates are a part of these health professionals. Dentistry, nursing, optometry, pharmacy, occupational therapy, physical therapy and other health professions are all part of health care, it includes work done in providing primary care, secondary care, tertiary care, as well as in public health. Access to health care may vary across countries and individuals influenced by social and economic conditions as well as health policies. Health care systems are organizations established to meet the health needs of targeted populations. According to the World Health Organization, a well-functioning health care system requires a financing mechanism, a well-trained and adequately paid workforce, reliable information on which to base decisions and policies, well maintained health facilities to deliver quality medicines and technologies.
An efficient health care system can contribute to a significant part of a country's economy and industrialization. Health care is conventionally regarded as an important determinant in promoting the general physical and mental health and well-being of people around the world. An example of this was the worldwide eradication of smallpox in 1980, declared by the WHO as the first disease in human history to be eliminated by deliberate health care interventions; the delivery of modern health care depends on groups of trained professionals and paraprofessionals coming together as interdisciplinary teams. This includes professionals in medicine, physiotherapy, dentistry and allied health, along with many others such as public health practitioners, community health workers and assistive personnel, who systematically provide personal and population-based preventive and rehabilitative care services. While the definitions of the various types of health care vary depending on the different cultural, political and disciplinary perspectives, there appears to be some consensus that primary care constitutes the first element of a continuing health care process and may include the provision of secondary and tertiary levels of care.
Health care can be defined as either private. Primary care refers to the work of health professionals who act as a first point of consultation for all patients within the health care system; such a professional would be a primary care physician, such as a general practitioner or family physician. Another professional would be a licensed independent practitioner such as a physiotherapist, or a non-physician primary care provider such as a physician assistant or nurse practitioner. Depending on the locality, health system organization the patient may see another health care professional first, such as a pharmacist or nurse. Depending on the nature of the health condition, patients may be referred for secondary or tertiary care. Primary care is used as the term for the health care services that play a role in the local community, it can be provided in different settings, such as Urgent care centers which provide same day appointments or services on a walk-in basis. Primary care involves the widest scope of health care, including all ages of patients, patients of all socioeconomic and geographic origins, patients seeking to maintain optimal health, patients with all types of acute and chronic physical and social health issues, including multiple chronic diseases.
A primary care practitioner must possess a wide breadth of knowledge in many areas. Continuity is a key characteristic of primary care, as patients prefer to consult the same practitioner for routine check-ups and preventive care, health education, every time they require an initial consultation about a new health problem; the International Classification of Primary Care is a standardized tool for understanding and analyzing information on interventions in primary care based on the reason for the patient's visit. Common chronic illnesses treated in primary care may include, for example: hypertension, asthma, COPD, depression and anxiety, back pain, arthritis or thyroid dysfunction. Primary care includes many basic maternal and child health care services, such as family planning services and vaccinations. In the United States, the 2013 National Health Interview Survey found that skin disorders and joint disorders, back problems, disorders of lipid metabolism, upper respiratory tract disease were the most common reasons for accessing a physician.
In the United States, primary care physicians have begun to deliver primary care outside of the managed care system through direct primary care, a subset of the more familiar concierge medicine. Physicians in this model bill patients directly for services, either on a pre-paid monthly, quarterly, or annual basis, or bill for each service in the office. Examples of direct primary care practices include Foundation Health in Colorado and Qliance in Washington. In context of global population aging, with increasing numbers of older adults at greater risk of chronic non-communicable diseases increasing demand for primary care services is expected in both developed and developing countries; the World Health Organization attributes the provision of essential primary care as an integral component of an inclusive primary health care strategy. Secondary care includes acute care: nec
United States dollar
The United States dollar is the official currency of the United States and its territories per the United States Constitution since 1792. In practice, the dollar is divided into 100 smaller cent units, but is divided into 1000 mills for accounting; the circulating paper money consists of Federal Reserve Notes that are denominated in United States dollars. Since the suspension in 1971 of convertibility of paper U. S. currency into any precious metal, the U. S. dollar is, de facto, fiat money. As it is the most used in international transactions, the U. S. dollar is the world's primary reserve currency. Several countries use it as their official currency, in many others it is the de facto currency. Besides the United States, it is used as the sole currency in two British Overseas Territories in the Caribbean: the British Virgin Islands and Turks and Caicos Islands. A few countries use the Federal Reserve Notes for paper money, while still minting their own coins, or accept U. S. dollar coins. As of June 27, 2018, there are $1.67 trillion in circulation, of which $1.62 trillion is in Federal Reserve notes.
Article I, Section 8 of the U. S. Constitution provides that the Congress has the power "To coin money". Laws implementing this power are codified at 31 U. S. C. § 5112. Section 5112 prescribes the forms; these coins are both designated in Section 5112 as "legal tender" in payment of debts. The Sacagawea dollar is one example of the copper alloy dollar; the pure silver dollar is known as the American Silver Eagle. Section 5112 provides for the minting and issuance of other coins, which have values ranging from one cent to 100 dollars; these other coins are more described in Coins of the United States dollar. The Constitution provides that "a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time"; that provision of the Constitution is made specific by Section 331 of Title 31 of the United States Code. The sums of money reported in the "Statements" are being expressed in U. S. dollars. The U. S. dollar may therefore be described as the unit of account of the United States.
The word "dollar" is one of the words in the first paragraph of Section 9 of Article I of the Constitution. There, "dollars" is a reference to the Spanish milled dollar, a coin that had a monetary value of 8 Spanish units of currency, or reales. In 1792 the U. S. Congress passed a Coinage Act. Section 9 of that act authorized the production of various coins, including "DOLLARS OR UNITS—each to be of the value of a Spanish milled dollar as the same is now current, to contain three hundred and seventy-one grains and four sixteenth parts of a grain of pure, or four hundred and sixteen grains of standard silver". Section 20 of the act provided, "That the money of account of the United States shall be expressed in dollars, or units... and that all accounts in the public offices and all proceedings in the courts of the United States shall be kept and had in conformity to this regulation". In other words, this act designated the United States dollar as the unit of currency of the United States. Unlike the Spanish milled dollar, the U.
S. dollar is based upon a decimal system of values. In addition to the dollar the coinage act established monetary units of mill or one-thousandth of a dollar, cent or one-hundredth of a dollar, dime or one-tenth of a dollar, eagle or ten dollars, with prescribed weights and composition of gold, silver, or copper for each, it was proposed in the mid-1800s that one hundred dollars be known as a union, but no union coins were struck and only patterns for the $50 half union exist. However, only cents are in everyday use as divisions of the dollar. XX9 per gallon, e.g. $3.599, more written as $3.599⁄10. When issued in circulating form, denominations equal to or less than a dollar are emitted as U. S. coins while denominations equal to or greater than a dollar are emitted as Federal Reserve notes. Both one-dollar coins and notes are produced today, although the note form is more common. In the past, "paper money" was issued in denominations less than a dollar and gold coins were issued for circulation up to the value of $20.
The term eagle was used in the Coinage Act of 1792 for the denomination of ten dollars, subsequently was used in naming gold coins. Paper currency less than one dollar in denomination, known as "fractional currency", was sometimes pejoratively referred to as "shinplasters". In 1854, James Guthrie Secretary of the Treasury, proposed creating $100, $50 and $25 gold coins, which were referred to as a "Union", "Half Union", "Quarter Union", thus implying a denomination of 1 Union = $100. Today, USD notes are made from cotton fiber paper, unlike most common paper, made of wood fiber. U. S. coins are produced by the United States Mint. U. S. dollar banknotes are printed by the Bureau of Engraving and Printing and, since 1914, have been issued by t
Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy; some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world; the word aviation was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the verb avier, itself derived from the Latin word avis and the suffix -ation. There are early legends of human flight such as the stories of Icarus in Greek myth and Jamshid and Shah Kay Kāvus in Persian myth.
Somewhat more credible claims of short-distance human flights appear, such as the flying automaton of Archytas of Tarentum, the winged flights of Abbas ibn Firnas, Eilmer of Malmesbury, the hot-air Passarola of Bartholomeu Lourenço de Gusmão. The modern age of aviation began with the first untethered human lighter-than-air flight on November 21, 1783, of a hot air balloon designed by the Montgolfier brothers; the practicality of balloons was limited. It was recognized that a steerable, or dirigible, balloon was required. Jean-Pierre Blanchard flew the first human-powered dirigible in 1784 and crossed the English Channel in one in 1785. Rigid airships became the first aircraft to transport passengers and cargo over great distances; the best known aircraft of this type were manufactured by the German Zeppelin company. The most successful Zeppelin was the Graf Zeppelin, it flew over one million miles, including an around-the-world flight in August 1929. However, the dominance of the Zeppelins over the airplanes of that period, which had a range of only a few hundred miles, was diminishing as airplane design advanced.
The "Golden Age" of the airships ended on May 6, 1937 when the Hindenburg caught fire, killing 36 people. The cause of the Hindenburg accident was blamed on the use of hydrogen instead of helium as the lift gas. An internal investigation by the manufacturer revealed that the coating used in the material covering the frame was flammable and allowed static electricity to build up in the airship. Changes to the coating formulation reduced the risk of further Hindenburg type accidents. Although there have been periodic initiatives to revive their use, airships have seen only niche application since that time. In 1799, Sir George Cayley set forth the concept of the modern airplane as a fixed-wing flying machine with separate systems for lift and control. Early dirigible developments included machine-powered propulsion, rigid frames and improved speed and maneuverability There are many competing claims for the earliest powered, heavier-than-air flight; the first recorded powered flight was carried out by Clément Ader on October 9, 1890 in his bat-winged self-propelled fixed-wing aircraft, the Ader Éole.
It was the first manned, heavier-than-air flight of a significant distance but insignificant altitude from level ground. Seven years on 14 October 1897, Ader's Avion III was tested without success in front of two officials from the French War ministry; the report on the trials was not publicized until 1910. In November 1906 Ader claimed to have made a successful flight on 14 October 1897, achieving an "uninterrupted flight" of around 300 metres. Although believed at the time, these claims were discredited; the Wright brothers made the first successful powered and sustained airplane flight on December 17, 1903, a feat made possible by their invention of three-axis control. Only a decade at the start of World War I, heavier-than-air powered aircraft had become practical for reconnaissance, artillery spotting, attacks against ground positions. Aircraft began to transport people and cargo as designs grew more reliable; the Wright brothers took aloft the first passenger, Charles Furnas, one of their mechanics, on May 14, 1908.
During the 1920s and 1930s great progress was made in the field of aviation, including the first transatlantic flight of Alcock and Brown in 1919, Charles Lindbergh's solo transatlantic flight in 1927, Charles Kingsford Smith's transpacific flight the following year. One of the most successful designs of this period was the Douglas DC-3, which became the first airliner to be profitable carrying passengers starting the modern era of passenger airline service. By the beginning of World War II, many towns and cities had built airports, there were numerous qualified pilots available; the war brought many innovations to aviation, including the first jet aircraft and the first liquid-fueled rockets. After World War II in North America, there was a boom in general aviation, both private and commercial, as thousands of pilots were released from military service and many inexpensive war-surplus transport and training aircraft became available. Manufacturers such as Cessna and Beechcraft expanded production to provide light aircraft for the new middle-class market.
