Philadelphia, sometimes known colloquially as Philly, is the largest city in the U. S. state and Commonwealth of Pennsylvania, the sixth-most populous U. S. city, with a 2017 census-estimated population of 1,580,863. Since 1854, the city has been coterminous with Philadelphia County, the most populous county in Pennsylvania and the urban core of the eighth-largest U. S. metropolitan statistical area, with over 6 million residents as of 2017. Philadelphia is the economic and cultural anchor of the greater Delaware Valley, located along the lower Delaware and Schuylkill Rivers, within the Northeast megalopolis; the Delaware Valley's population of 7.2 million ranks it as the eighth-largest combined statistical area in the United States. William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 at the Second Continental Congress, the Constitution at the Philadelphia Convention of 1787.
Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress, the preservation of the Liberty Bell, the Battle of Germantown, the Siege of Fort Mifflin. Philadelphia was one of the nation's capitals during the revolution, served as temporary U. S. capital while Washington, D. C. was under construction. In the 19th century, Philadelphia became a railroad hub; the city grew from an influx of European immigrants, most of whom came from Ireland and Germany—the three largest reported ancestry groups in the city as of 2015. In the early 20th century, Philadelphia became a prime destination for African Americans during the Great Migration after the Civil War, as well as Puerto Ricans; the city's population doubled from one million to two million people between 1890 and 1950. The Philadelphia area's many universities and colleges make it a top study destination, as the city has evolved into an educational and economic hub. According to the Bureau of Economic Analysis, the Philadelphia area had a gross domestic product of US$445 billion in 2017, the eighth-largest metropolitan economy in the United States.
Philadelphia is the center of economic activity in Pennsylvania and is home to five Fortune 1000 companies. The Philadelphia skyline is expanding, with a market of 81,900 commercial properties in 2016, including several nationally prominent skyscrapers. Philadelphia has more outdoor murals than any other American city. Fairmount Park, when combined with the adjacent Wissahickon Valley Park in the same watershed, is one of the largest contiguous urban park areas in the United States; the city is known for its arts, culture and colonial history, attracting 42 million domestic tourists in 2016 who spent US$6.8 billion, generating an estimated $11 billion in total economic impact in the city and surrounding four counties of Pennsylvania. Philadelphia has emerged as a biotechnology hub. Philadelphia is the birthplace of the United States Marine Corps, is the home of many U. S. firsts, including the first library, medical school, national capital, stock exchange and business school. Philadelphia contains 67 National Historic Landmarks and the World Heritage Site of Independence Hall.
The city became a member of the Organization of World Heritage Cities in 2015, as the first World Heritage City in the United States. Although Philadelphia is undergoing gentrification, the city maintains mitigation strategies to minimize displacement of homeowners in gentrifying neighborhoods. Before Europeans arrived, the Philadelphia area was home to the Lenape Indians in the village of Shackamaxon; the Lenape are a Native American tribe and First Nations band government. They are called Delaware Indians, their historical territory was along the Delaware River watershed, western Long Island, the Lower Hudson Valley. Most Lenape were pushed out of their Delaware homeland during the 18th century by expanding European colonies, exacerbated by losses from intertribal conflicts. Lenape communities were weakened by newly introduced diseases smallpox, violent conflict with Europeans. Iroquois people fought the Lenape. Surviving Lenape moved west into the upper Ohio River basin; the American Revolutionary War and United States' independence pushed them further west.
In the 1860s, the United States government sent most Lenape remaining in the eastern United States to the Indian Territory under the Indian removal policy. In the 21st century, most Lenape reside in Oklahoma, with some communities living in Wisconsin, in their traditional homelands. Europeans came to the Delaware Valley in the early 17th century, with the first settlements founded by the Dutch, who in 1623 built Fort Nassau on the Delaware River opposite the Schuylkill River in what is now Brooklawn, New Jersey; the Dutch considered the entire Delaware River valley to be part of their New Netherland colony. In 1638, Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina and spread out in the valley. In 1644, New Sweden supported the Susquehannocks in their military defeat of the English colony of Maryland. In 1648, the Dutch built Fort Beversreede on the west bank of the Delaware, south of the Schuylkill near the present-day Eastwick neighborhood, to reassert their dominion over the area.
The Swedes responded by building Fort Nya Korsholm, or New Korsholm, named after a town in Finland with a Swedish majority. In 1655, a
Times Square is a major commercial intersection, tourist destination, entertainment center and neighborhood in the Midtown Manhattan section of New York City at the junction of Broadway and Seventh Avenue. It stretches from West 42nd to West 47th Streets. Brightly adorned with billboards and advertisements, Times Square is sometimes referred to as "The Crossroads of the World", "The Center of the Universe", "the heart of The Great White Way", "the heart of the world". One of the world's busiest pedestrian areas, it is the hub of the Broadway Theater District and a major center of the world's entertainment industry. Times Square is one of the world's most visited tourist attractions, drawing an estimated 50 million visitors annually. 330,000 people pass through Times Square daily, many of them tourists, while over 460,000 pedestrians walk through Times Square on its busiest days. Known as Longacre Square, Times Square was renamed in 1904 after The New York Times moved its headquarters to the newly erected Times Building – now One Times Square – the site of the annual New Year's Eve ball drop which began on December 31, 1907, continues today, attracting over a million visitors to Times Square every year.
Times Square functions as a town square, but is not geometrically a square. Broadway runs diagonally, crossing through the horizontal and vertical street grid of Manhattan laid down by the Commissioners' Plan of 1811, that intersection creates the "bowtie" shape of Times Square; the southern triangle of Times Square has no specific name, but the northern triangle is called Father Duffy Square. It was dedicated in 1937 to Chaplain Francis P. Duffy of New York City's U. S. 69th Infantry Regiment and is the site of a memorial to him, along with a statue of George M. Cohan, as well as the TKTS reduced-price ticket booth run by the Theatre Development Fund. Since 2008, the booth has been backed by a red, triangular set of bleacher-like stairs, used by people to sit, talk and take photographs; when Manhattan Island was first settled by the Dutch, three small streams united near what is now 10th Avenue and 40th Street. These three streams formed the "Great Kill". From there the Great Kill wound through the low-lying Reed Valley, known for fish and waterfowl and emptied into a deep bay in the Hudson River at the present 42nd Street.
The name was retained in a tiny hamlet, Great Kill, that became a center for carriage-making, as the upland to the south and east became known as Longacre. Before and after the American Revolution, the area belonged to John Morin Scott, a general of the New York militia, in which he served under George Washington. Scott's manor house was at what is 43rd Street, surrounded by countryside used for farming and breeding horses. In the first half of the 19th century, it became one of the prized possessions of John Jacob Astor, who made a second fortune selling off lots to hotels and other real estate concerns as the city spread uptown. By 1872, the area had become the center of New York's horse carriage industry; the locality had not been given a name, city authorities called it Longacre Square after Long Acre in London, where the horse and carriage trade was centered in that city. William Henry Vanderbilt ran the American Horse Exchange there. In 1910 it became the Winter Garden Theatre; as more profitable commerce and industrialization of Lower Manhattan pushed homes and prostitution northward from the Tenderloin District, Long Acre Square became nicknamed the Thieves Lair for its rollicking reputation as a low entertainment district.
The first theater on the square, the Olympia, was built by cigar manufacturer and impresario Oscar Hammerstein I. According to Gotham: A History of New York City to 1898, "By the early 1890s this once sparsely settled stretch of Broadway was ablaze with electric light and thronged by crowds of middle- and upper-class theatre and cafe patrons." In 1904, New York Times publisher Adolph S. Ochs moved the newspaper's operations to a new skyscraper on 42nd Street at Longacre Square, on the site of the former Pabst Hotel, which had existed on the site for less than a decade since it opened in November 1899. Ochs persuaded Mayor George B. McClellan Jr. to construct a subway station there, the area was renamed "Times Square" on April 8, 1904. Just three weeks the first electrified advertisement appeared on the side of a bank at the corner of 46th Street and Broadway; the north end became Duffy Square, the former Horse Exchange became the Winter Garden Theatre, constructed in 1911. The New York Times moved to more spacious offices one block west of the square in 1913 and sold the building in 1961.
The old Times Building was named the Allied Chemical Building in 1963. Now known as One Times Square, it is famed for the Times Square Ball drop on its roof every New Year's Eve. In 1913, the Lincoln Highway Association, headed by entrepreneur Carl G. Fisher, chose the intersection of 42nd Street and Broadway to be the Eastern Terminus of the Lincoln Highway; this was the first road across the United States, which spanned 3,389 miles coast-to-coast through 13 states to its western terminus in Lincoln Park in San Francisco, California. Times Square grew after World War I, it became a cultural hub full of theatres, music halls, upscale hotels. Times Square became New York's agora, a place to gather to await great tidings and to celebrate them, whether a World Series or a presidential election. Advertising grew in the 1920s, growing
Korean Air Lines Co. Ltd. operating as Korean Air, is the largest airline and flag carrier of South Korea based on fleet size, international destinations and international flights. The airline's global headquarters are located in South Korea. Korean Air was founded as Korean National Airlines in 1946. After several years of service and expansion, the airline was privatized in 1969. Korean Air's international passenger division and related subsidiary cargo division together serve 127 cities in 44 countries, while its domestic division serves 12 destinations, it is among the top 20 airlines in the world in terms of passengers carried and is the top-ranked international cargo airline. Incheon International Airport serves as Korean Air's international hub. Korean Air maintains a satellite headquarters campus at Incheon; the majority of Korean Air's pilots, ground staff, flight attendants are based in Seoul. Korean Air is the parent company of Jin Air and is a founding member of the SkyTeam airline alliance.
It was voted Asia's best airline by Business Traveler readers in 2012. Korean Air was founded by the South Korean government in 1962 as Korean Air Lines to replace Korean National Airlines, founded in 1946. On March 1, 1969, the Hanjin Transport Group took control of the airline. Long-haul freight operations were introduced on April 26, 1971, followed by passenger services to Los Angeles International Airport on April 19, 1972. International flights to Hong Kong and Los Angeles were flown with Boeing 707s until the introduction of the Boeing 747 in 1973. In 1973, the airline introduced Boeing 747s on its Pacific routes and started a European service to Paris, France using the 707 and McDonnell Douglas DC-10. In 1975, the airline became one of the earliest Asian airlines to operate Airbus aircraft with the purchase of three Airbus A300s, which were put into immediate service on Asian routes. Since South Korean aircraft were prohibited from flying in the airspace of North Korea and the Soviet Union at the time, the European routes had to be designed eastbound from South Korea, such as Gimpo-Anchorage-Paris.
A blue-top and redesigned livery with a new corporate "Korean Air" logo featuring a stylized Taegeuk design was introduced on March 1, 1984, the airline's name changed to Korean Air from Korean Air Lines. This livery was introduced on its Fokker F28 Boeing 747-300s, it was designed in cooperation between Korean Boeing. In the 1990s, Korean Air became the first airline to use the new McDonnell Douglas MD-11 to supplement its new fleet of Boeing 747-400 aircraft; some older 747 aircraft were converted for freight service. In the 1980s, Korean Air's head office was in the KAL Building on Jung-gu, Seoul. On June 5, 2007, Korean Air said that it would create a new low-cost carrier called Jin Air in Korea to compete with Korea's KTX high-speed railway network system, which offered cheaper fares and less stringent security procedures compared to air travel. Jin Air started its scheduled passenger service from Seoul to Jeju on July 17, 2008. Korean Air announced that some of its A300s would be given to Jin Air.
By 2009, Korean Air's image had become more prestigious, differing from the airline's late-1990s image, tarnished by several fatal accidents. In mid-2010, a co-marketing deal with games company Blizzard Entertainment sent a 747-400 and a 737-900 taking to the skies wrapped in StarCraft II branding. In August 2010, Korean Air announced heavy second-quarter losses despite record high revenue. In August 2010, Hanjin Group, the parent of Korean, opened a new cargo terminal at Navoi in Uzbekistan, which will become a cargo hub with regular Incheon-Navoi-Milan flights. Korean Air owns the Hyatt in Incheon; this building in downtown Los Angeles will house the largest InterContinental Hotel in the Americas in what will be the tallest building in Los Angeles. In 2013, Korean Air acquired a 44% stake in Czech Airlines, it sold the stake in October 2017. Korean Air's headquarters, the Korean Air Operations Center, is located in Gonghang-dong, Gangseo-gu in Seoul. Korean Air has offices at Gimpo International Airport in Seoul.
Korean Air's other hubs are at Jeju International Airport and Gimhae International Airport, Busan. The maintenance facilities are located in Gimhae International Airport; the airline had 20,540 employees as of December 2014. Korean Air serves 123 international destinations in 50 countries on 5 continents, excluding codeshares; the airline’s international hub is Incheon International Airport. The airline flies 13 domestic destinations within South Korea. KAL operates between Incheon and 22 cities in mainland China, along with Asiana Airlines, it is one of the two largest foreign airlines to operate into the People's Republic of China. Korean Air has codeshare agreements with the following airlines: Korean Air has interline agreements with the following airlines: Korean Air is an airline partner of Skywards, the frequent-flyer program for Emirates. Skywards members can redeem miles for free flights; as of March 2019, the Korean Air fleet consists of the following aircraft: Korean Air has operated the following aircraft: At the Association of Asia Pacific Airlines Assembly in 2018, Korean Air announced that it was considering a new large widebody aircraft order.
Types under consideration for replacement of older widebody aircraft in the fleet include the Boeing
In building construction, topping out is a builders' rite traditionally held when the last beam is placed atop a structure during its construction. Nowadays, the ceremony is parlayed into a media event for public relations purposes, it has since come to mean more finishing the structure of the building, whether there is a ceremony or not. The practice of "topping out" a new building can be traced to the ancient Scandinavian religious rite of placing a tree atop a new building to appease the tree-dwelling spirits displaced in its construction. Long an important component of timber frame building, it migrated to England and Northern Europe, thence to the Americas. A tree or leafy branch is placed on the topmost wood or iron beam with flags and streamers tied to it. A toast is drunk and sometimes workers are treated to a meal. In masonry construction the rite celebrates the bedding of the last brick. In some cases a topping out event is held at an intermediate point, such as when the roof is dried-in, which means the roof can provide at least semi-permanent protection from the elements.
The practice remains common in the United Kingdom and assorted Commonwealth countries such as Australia, Canada as well as Germany, Slovenia, Chile, Czech Republic, Poland, the Baltic States, the United States, where the last beam of a skyscraper is painted white and signed by all the workers involved. In New Zealand, completion of the roof to a water-proof state is celebrated through a "roof shout", where workers are treated to cake and beer; the tradition of "pannenbier" is popular in the Netherlands and Flanders, where a national, regional or city flag is hung once the highest point of a building is reached. It stays in place until the building's owner provides free beer to the workers, after which it is lowered, it is considered greedy. Groundbreaking John V. Robinson.

A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of flat surfaces, a fabricated helipad provides a marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing aircraft, may be called vertiports. An example is Vertiport Chicago, which opened in 2015. Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located remote from populated areas due to sounds, winds and cost constraints, some skyscrapers maintain a helipad on their roofs in order to accommodate air taxi services; some basic helipads are built on highrise buildings for evacuation in case of a major fire outbreak. Major police departments may use a dedicated helipad at heliports as a base for police helicopters. Large ships and oil platforms have a helipad on board for emergency use.
In such a case, the term "helideck" or "helodeck" has been used in the meaning of a helipad on board. Helipads are common features at hospitals where they serve to facilitate medical evacuation or air ambulance transfers of patients to trauma centers or to accept patients from remote areas without local hospitals or facilities capable of providing the level of emergency medicine required. In urban environments, these heliports are located on the roof of the hospital. Rooftop helipads sometimes display a large two-digit number, representing the weight limit of the pad. In addition, a second number may be present. Location identifiers are but not always, issued for helipads, they may be issued by the appropriate aviation authority. Authorized agencies include the Federal Aviation Administration in the United States, Transport Canada in Canada, the International Civil Aviation Organization, the International Air Transport Association; some helipads may have location identifiers from multiple sources, these identifiers may be of different format and name.
Helipads are constructed out of concrete and are marked with a circle and/or a letter "H", so as to be visible from the air. However, they are not always constructed out of concrete. Rig mats may be used to build helipads. Landing pads may be constructed in extreme conditions such as on ice; the world's highest helipad, built by India, is located on the Siachen Glacier at a height of 21,000 feet above sea level. The world's largest heliport is in Morgan City and has a total of 46 helipads, used to support offshore oil platforms in the Gulf of Mexico. A portable helipad is a helipad structure with a rugged frame that can be used to land helicopters in any areas with slopes of up to 30 degrees, such as hillsides and boggy areas. Portable helipads can be transported by helicopter or powered-lift to place them where a VTOL needs to land, as long as there are no insurmountable obstructions nearby.

Home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California.
The city was founded on September 4, 1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence. In 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, becoming part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood; the discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California assured the city's continued rapid growth; the Los Angeles coastal area was settled by the Chumash tribes. A Gabrieleño settlement in the area was called iyáangẚ, meaning "poison oak place". Maritime explorer Juan Rodríguez Cabrillo claimed the area of southern California for the Spanish Empire in 1542 while on an official military exploring expedition moving north along the Pacific coast from earlier colonizing bases of New Spain in Central and South America.
Gaspar de Portolà and Franciscan missionary Juan Crespí, reached the present site of Los Angeles on August 2, 1769. In 1771, Franciscan friar Junípero Serra directed the building of the Mission San Gabriel Arcángel, the first mission in the area. On September 4, 1781, a group of forty-four settlers known as "Los Pobladores" founded the pueblo they called El Pueblo de Nuestra Señora la Reina de los Ángeles,'The Town of Our Lady the Queen of the Angels'; the present-day city has the largest Roman Catholic Archdiocese in the United States. Two-thirds of the Mexican or settlers were mestizo or mulatto, a mixture of African and European ancestry; the settlement remained a small ranch town for decades, but by 1820, the population had increased to about 650 residents. Today, the pueblo is commemorated in the historic district of Los Angeles Pueblo Plaza and Olvera Street, the oldest part of Los Angeles. New Spain achieved its independence from the Spanish Empire in 1821, the pueblo continued as a part of Mexico.
During Mexican rule, Governor Pío Pico made Los Angeles Alta California's regional capital. Mexican rule ended during the Mexican–American War: Americans took control from the Californios after a series of battles, culminating with the signing of the Treaty of Cahuenga on January 13, 1847. Railroads arrived with the completion of the transcontinental Southern Pacific line to Los Angeles in 1876 and the Santa Fe Railroad in 1885. Petroleum was discovered in the city and surrounding area in 1892, by 1923, the discoveries had helped California become the country's largest oil producer, accounting for about one-quarter of the world's petroleum output. By 1900, the population had grown to more than 102,000; the completion of the Los Angeles Aqueduct in 1913, under the supervision of William Mulholland, assured the continued growth of the city. Due to clauses in the city's charter that prevented the City of Los Angeles from selling or providing water from the aqueduct to any area outside its borders, many adjacent city and communities became compelled to annex themselves into Los Angeles.
Los Angeles created the first municipal zoning ordinance in the United States. On September 14, 1908, the Los Angeles City Council promulgated residential and industrial land use zones; the new ordinance established three residential zones of a single type, where industrial uses were

Chicago has professional sports teams in each of the major professional leagues, including two Major League Baseball teams; the name "Chicago" is derived from a French rendering of the indigenous Miami-Illinois word shikaakwa for a wild relative of the onion, known to botanists as Allium tricoccum and known more as ramps.
The first known reference to the site of the current city of Chicago as "Checagou" was by Robert de LaSalle around 1679 in a memoir. Henri Joutel, in his journal of 1688, noted that the eponymous wild "garlic" grew abundantly in the area. According to his diary of late September 1687:...when we arrived at the said place called "Chicagou" which, according to what we were able to learn of it, has taken this name because of the quantity of garlic which grows in the forests in this region. The city has had several nicknames throughout its history such as the Windy City, Chi-Town, Second City, the City of the Big Shoulders, which refers to the city's numerous skyscrapers and high-rises. In the mid-18th century, the area was inhabited by a Native American tribe known as the Potawatomi, who had taken the place of the Miami and Sauk and Fox peoples; the first known non-indigenous permanent settler in Chicago was Jean Baptiste Point du Sable. Du Sable arrived in the 1780s, he is known as the "Founder of Chicago".
