Munich
–
Munich is the capital and largest city of the German state of Bavaria, on the banks of River Isar north of the Bavarian Alps. Munich is the third largest city in Germany, after Berlin and Hamburg, the Munich Metropolitan Region is home to 5.8 million people. According to the Globalization and World Rankings Research Institute Munich is considered an alpha-world city, the name of the city is derived from the Old/Middle High German term Munichen, meaning by the monks. It derives from the monks of the Benedictine order who ran a monastery at the place that was later to become the Old Town of Munich, Munich was first mentioned in 1158. From 1255 the city was seat of the Bavarian Dukes, black and gold—the colours of the Holy Roman Empire—have been the citys official colours since the time of Ludwig the Bavarian, when it was an imperial residence. Following a final reunification of the Wittelsbachian Duchy of Bavaria, previously divided and sub-divided for more than 200 years, like wide parts of the Holy Roman Empire, the area recovered slowly economically. In 1918, during the German Revolution, the house of Wittelsbach, which governed Bavaria since 1180, was forced to abdicate in Munich. In the 1920s, Munich became home to political factions, among them the NSDAP. During World War II, Munich was heavily bombed and more than 50% of the entire city, the postwar period was characterised by American occupation until 1949 and a strong increase of population and economic power during the years of the Wirtschaftswunder after 1949. The city is home to corporations like BMW, Siemens, MAN, Linde, Allianz and MunichRE as well as many small. Munich is home to national and international authorities, major universities, major museums. Its numerous architectural attractions, international events, exhibitions and conferences. Munich is one of the most prosperous and fastest growing cities in Germany and it is a top-ranked destination for migration and expatriate location, despite being the municipality with the highest density of population in Germany. Munich nowadays hosts more than 530,000 people of foreign background, the year 1158 is assumed to be the foundation date, which is the earliest date the city is mentioned in a document. The document was signed in Augsburg, by that time the Guelph Henry the Lion, Duke of Saxony and Bavaria, had built a bridge over the river Isar next to a settlement of Benedictine monks—this was on the Old Salt Route and a toll bridge. In 1175, Munich was officially granted city status and received fortification, in 1180, with the trial of Henry the Lion, Otto I Wittelsbach became Duke of Bavaria and Munich was handed over to the Bishop of Freising. In 1240, Munich was transferred to Otto II Wittelsbach and in 1255, Duke Louis IV, a native of Munich, was elected German king in 1314 and crowned as Holy Roman Emperor in 1328. He strengthened the position by granting it the salt monopoly

Germany
–
Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

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

Concrete
–
Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, when aggregate is mixed together with dry Portland cement and water, the mixture forms a fluid slurry that is easily poured and molded into shape. The cement reacts chemically with the water and other ingredients to form a matrix that binds the materials together into a durable stone-like material that has many uses. Often, additives are included in the mixture to improve the properties of the wet mix or the finished material. Most concrete is poured with reinforcing materials embedded to provide tensile strength, famous concrete structures include the Hoover Dam, the Panama Canal, and the Roman Pantheon. The earliest large-scale users of technology were the ancient Romans. The Colosseum in Rome was built largely of concrete, and the dome of the Pantheon is the worlds largest unreinforced concrete dome. Today, large concrete structures are made with reinforced concrete. After the Roman Empire collapsed, use of concrete became rare until the technology was redeveloped in the mid-18th century, today, concrete is the most widely used man-made material. The word concrete comes from the Latin word concretus, the passive participle of concrescere, from con-. Perhaps the earliest known occurrence of cement was twelve years ago. A deposit of cement was formed after an occurrence of oil shale located adjacent to a bed of limestone burned due to natural causes and these ancient deposits were investigated in the 1960s and 1970s. On a human timescale, small usages of concrete go back for thousands of years and they discovered the advantages of hydraulic lime, with some self-cementing properties, by 700 BC. They built kilns to supply mortar for the construction of houses, concrete floors. The cisterns were kept secret and were one of the reasons the Nabataea were able to thrive in the desert, some of these structures survive to this day. In the Ancient Egyptian and later Roman eras, it was re-discovered that adding volcanic ash to the mix allowed it to set underwater, similarly, the Romans knew that adding horse hair made concrete less liable to crack while it hardened, and adding blood made it more frost-resistant. Crystallization of strätlingite and the introduction of pyroclastic clays creates further fracture resistance, german archaeologist Heinrich Schliemann found concrete floors, which were made of lime and pebbles, in the royal palace of Tiryns, Greece, which dates roughly to 1400–1200 BC. Lime mortars were used in Greece, Crete, and Cyprus in 800 BC, the Assyrian Jerwan Aqueduct made use of waterproof concrete

Munich Airport
–
Munich Airport, German, Flughafen München, is a major international airport near Munich, the capital of Bavaria. It is the second busiest airport in Germany in terms of traffic behind Frankfurt Airport. It is the worlds 15th busiest airport in terms of passenger traffic. As of February 2017, the airport features flights to 248 destinations, Munich Airport serves as the secondary hub for Lufthansa including Lufthansa Regional and its Star Alliance partners besides Frankfurt. The airport is located 28.5 km northeast of Munich near the old city of Freising and is named in memory of the former Bavarian Prime Minister Franz Josef Strauss, from 1939 to 1992, Munich was served by Munich-Riem Airport. First plans to expand or build a new airport were made in 1954 owing to the traffic flow-rate, the decision for building the new airport at Erdinger Moos was made on 5 August 1969 by the Bavarian government. When construction started on 3 November 1980, a village named Franzheim was demolished, the airport is located on the territory of four different municipalities, Oberding, Hallbergmoos, Freising, and Marzling in the district of Freising. The airport is named after Franz Josef Strauß, who played a prominent, albeit sometimes controversial, amongst other positions, Strauß was a long-time Minister-President of the state of Bavaria, where the airport is located and was initiated under his government. Strauß, having been a pilot himself, had a particular interest in the aviation industry. He is regarded one of the fathers of Airbus and served as chairman of its supervisory board. Naming the airport by its full name Flughafen München Franz Josef Strauß is fairly uncommon, the company that owns and operates the airport is named Flughafen München GmbH and brands itself as M – Flughafen München or M – Munich Airport. In the Munich area, most people use the term Flughafen München, sometimes Flughafen München II in order to distinguish from the earlier airport, or simply MUC for its IATA-code. The new Munich Airport commenced operation on 17 May 1992, when moved from the former site at Munich-Riem Airport. While Lufthansa serves more European destinations from Munich Airport than from Frankfurt Airport, Frankfurt has many more intercontinental routes, between 1995 and 2006 passenger numbers doubled from under 15 million per annum to over 30 million, despite the impact of the 11 September attacks in 2001 and 2002. In 1996 the airport overtook Düsseldorf as Germanys second busiest airport, in June 2003 construction of Terminal 2 was completed and it was inaugurated as an exclusive facility for Lufthansa and its Star Alliance partners. In November 2013, the airport introduced its first new design since its inauguration. The large letter M remains in a new font type, There are also animated color-changing versions of the M-sign placed throughout the airport area, for example on the main entrance road and on the new Terminal 2 satellite. In May 2015, Munich Airport became the first airport outside Asia to be ranked as a 5-Star Airport by Skytrax and it also won Best Airport in Europe for the eighth time

International airport
–
An international airport is an airport that offers customs and immigration facilities for passengers travelling between countries. International airports often also host domestic flights, some, such as Frankfurt Airport in Germany are very large, others such as Faaā International Airport in Tahiti, are quite small. Buildings, operations and management have become increasingly sophisticated since the mid 20th century, detailed technical standards have been developed to ensure safety and common coding systems implemented to provide global consistency. The physical structures that serve millions of passengers and flights are among the most complex. In August 1919, Hounslow Heath Aerodrome, in London, England was the first airport to operate scheduled international commercial services and it was closed and supplanted by Croydon Airport in March 1920. In the United States, Douglas Municipal Airport in Arizona became the first international airport of the Americas in 1928, the precursors to international airports were airfields or aerodromes. In the early days of international flights, there was limited infrastructure, four-engined land planes being unavailable for over-water operations to international destinations, thus/therefore flying boats became part of the solution. At the far end of the longest international route, on-water landing areas were found in such as Surabaya. In Sydney, Rose Bay, New South Wales, was chosen as the landing area. International airports sometimes serve military as well as commercial purposes and their viability is also affected by technological developments, other international airports, such as Kai Tak Airport in Hong Kong, have been decommissioned and replaced when they reached capacity or technological advances rendered them inadequate. Airports may also be regarded as emblematic of national pride and so the design may be architecturally ambitious, an example is the planned New Mexico City international airport, intended to replace an airport that has reached capacity. Airports can be towered or non-towered, depending on air traffic density, because of high capacity and busy airspace, many international airports have air traffic control located on site. Construction of the expressway included the construction of two bridges and the Ma Wan viaduct on Ma Wan island to connect the bridges, each bridge carries rail and automobile traffic. International airports have commercial relationships with and provide services to airlines, many also serve as hubs, or places where non-direct flights may land and passengers may switch planes, while others serve primarily direct point-to-point flights. This affects airport design factors, including the number and placement of terminals as well as the flow of passengers, an airport specializing in point-to-point transit can have international and domestic terminals, each in their separate building equipped with separate baggage handling facilities. In a hub airport, however, spaces and services are shared, technical standards for safety and operating procedures at international airports are set by international agreements. The International Air Transport Association, formed in 1945, is the association of the airline companies, the International Civil Aviation Organization is a body of the United Nations succeeding earlier international committees going back to 1903. These two organizations served to create regulations over airports which the airports themselves had no authority to debate and this eventually sparked an entire subject of air travel politics

Bavaria
–
Bavaria is a free state and one of 16 federal states of Germany. Located in the German southeast with an area of 70,548 square kilometres and its territory comprises roughly a fifth of the total land area of Germany, and, with 12.9 million inhabitants, it is Germanys second most populous state. Munich, Bavarias capital and largest city, is the third largest city in Germany, the Duchy of Bavaria dates back to the year 555. In the 17th century CE, the Duke of Bavaria became a Prince-elector of the Holy Roman Empire, the Kingdom of Bavaria existed from 1806 to 1918, when Bavaria became a republic. In 1946, the Free State of Bavaria re-organised itself on democratic lines after the Second World War, Bavaria has a unique culture, largely because of the states Catholic majority and conservative traditions. Bavarians have traditionally been proud of their culture, which includes such as Oktoberfest. The state also has the second largest economy among the German states by GDP figures, modern Bavaria also includes parts of the historical regions of Franconia, Upper Palatinate and Swabia. The Bavarians emerged in a north of the Alps, previously inhabited by Celts. The Bavarians spoke Old High German but, unlike other Germanic groups, rather, they seem to have coalesced out of other groups left behind by Roman withdrawal late in the 5th century. These peoples may have included the Celtic Boii, some remaining Romans, Marcomanni, Allemanni, Quadi, Thuringians, Goths, Scirians, Rugians, the name Bavarian means Men of Baia which may indicate Bohemia, the homeland of the Celtic Boii and later of the Marcomanni. They first appear in written sources circa 520, a 17th century Jewish chronicler David Solomon Ganz, citing Cyriacus Spangenberg, claimed that the diocese was named after an ancient Bohemian king, Boiia, in the 14th century BCE. From about 554 to 788, the house of Agilolfing ruled the Duchy of Bavaria and their daughter, Theodelinde, became Queen of the Lombards in northern Italy and Garibald was forced to flee to her when he fell out with his Frankish overlords. Garibalds successor, Tassilo I, tried unsuccessfully to hold the frontier against the expansion of Slavs. Tassilos son Garibald II seems to have achieved a balance of power between 610 and 616, after Garibald II little is known of the Bavarians until Duke Theodo I, whose reign may have begun as early as 680. From 696 onwards he invited churchmen from the west to organize churches and his son, Theudebert, led a decisive Bavarian campaign to intervene in a succession dispute in the Lombard Kingdom in 714, and married his sister Guntrud to the Lombard King Liutprand. At Theodos death the duchy was divided among his sons, at Hugberts death the duchy passed to a distant relative named Odilo, from neighbouring Alemannia. He was defeated near Augsburg in 743 but continued to rule until his death in 748, saint Boniface completed the peoples conversion to Christianity in the early 8th century. Bavaria was in ways affected by the Protestant Reformation in the 16th century

Olympiapark (Munich)
–
The Olympiapark München in Munich, Germany, is an Olympic Park which was constructed for the 1972 Summer Olympics. Located in the Oberwiesenfeld neighborhood of Munich, the Park continues to serve as a venue for cultural, social, the Park is administered by Olympiapark München GmbH, a holding company fully owned by the state capital of Munich. Also in this area are the Aquatic Center and Olympic Event Hall, Olympic Village, comprising two villages, one male and one female. Olympia-Pressestadt, today the home of the Olympic Shopping Center, strictly speaking, this portion belongs to the area of district of Moosach. Olympic Park, Adjoining the Olympic Area to the south, this includes the Olympic Mountain. The park is located in the Milbertshofen-Am Hart borough near BMW Group headquarters, Georg-Brauchle-Ring divides the area into two halves, Olympic Village and Olympia Pressestadt to the north and Olympic Area and Olympic Park to the south. After the International Olympic Committee in 1966 awarded Munich the Olympic Games, up until 1939, Oberwiesenfeld had largely been used as an airfield, however, the then-recently opened Munich-Riem airport left the Oberwiesenfeld area largely idle. Under Nazi plans for the development of Munich into the Capital of the Movement, the Second World War, however, hindered the implementation of this plan. In October 1957, since the US Army had facilities at the Oberwiesefeld, apart from infrastructure projects such as the Oberwiesenfeld Ice Rink, Oberwiesenfeld remained largely vacant, and as such was an ideal place for the construction of the Olympic Stadium. The concept of a green Olympic Games was chosen, and so too was the orientation toward the ideals of democracy. Officials sought to integrate optimism toward the future with an attitude toward technology. The architecture firm of Günther Behnisch and its partners developed a master plan for the sports and recreation area. The landscape layout was designed by landscape architect Günther Grzimek, the eye-catching tensile structure that covers much of the park was designed by German architect and engineer Frei Otto with Günther Behnisch. In all, the project cost 1.35 billion German Marks to complete, using public transportation, the Munich U-Bahns U3 line provides a direct route, From Münchner Freiheit, the line connects to Olympiapark via Schwabing and the midtown area. In 2007, the U3 line was extended to continue on to Oberwiesenfeld station at the end of the Olympic Village. The continuation to Moosach, where the line connects to the S1 S-Bahn line, was completed in 2010, olympiazentrum U-Bahn station is a central stop for the MVG bus line. Between 1972 and 1988 the Olympiastadion Station existed, which was oft-snubbed at events, currently, the station is abandoned continues to decay. The Olympiapark is accessible by car via Mittlerer Ring motorway, the Olympic Village itself is closed off from car traffic

Adolf Galland
–
Adolf Joseph Ferdinand Galland was a German Luftwaffe general and flying ace who served throughout the Second World War in Europe. He flew 705 combat missions, and fought on the Western Front, on four occasions, he survived being shot down, and he was credited with 104 aerial victories, all of them against the Western Allies. Galland, who was born in Westerholt, Westphalia, became a pilot in 1929 before he joined Lufthansa. In 1932, he graduated as a pilot at the Deutsche Verkehrsfliegerschule in Braunschweig before applying to join the Reichswehr of the Weimar Republic later in the year, Gallands application was accepted, but he never took up the offer. In February 1934, he was transferred to the Luftwaffe, in 1937, during the Spanish Civil War, he volunteered for the Condor Legion and flew ground attack missions in support of the Nationalists under Francisco Franco. After finishing his tour in 1938 Galland was employed in the Air Ministry writing doctrinal and technical manuals about his experiences as a ground-attack pilot, during this period Galland served as an instructor for ground-attack units. During the German invasion of Poland in September 1939, he flew ground attack missions. In early 1940 Galland managed to persuade his superiors to him to become a fighter pilot. Galland flew Messerschmitt Bf 109s during the Battle of France and the Battle of Britain, by the end of 1940, his tally of victories had reached 57. In 1941, Galland stayed in France and fought the Royal Air Force over the English Channel, by November 1941, his tally had increased to 96, by which time he had earned the Knights Cross of the Iron Cross with Oak Leaves and Swords. As General der Jagdflieger, Galland was forbidden to fly combat missions, in late January and early February 1942, Galland first planned then commanded the Luftwaffes air cover for the Kriegsmarine Operation Cerberus which was a major success. It earned him the Knights Cross of the Iron Cross with Oak Leaves, over the ensuing years, Galland’s disagreements with Reichsmarschall Hermann Göring about how best to combat the Allied Air Forces bombing Germany caused their relationship to deteriorate. The Luftwaffe fighter force was under pressure by 1944. The relationship collapsed altogether in early January 1945, when Galland was relieved of his command because of his constant criticism of the Luftwaffe leadership. Galland was then put under house arrest following the so-called Fighter Pilots Revolt, in March 1945, Galland returned to operational flying and was permitted to form a jet fighter unit which he called Jagdverband 44. He flew missions over Germany until the end of the war in May, after the war, Galland was employed by Argentinas Government and acted as a consultant to the Argentine Air Force. Later, he returned to Germany and managed his own business, Galland also became friends with many former enemies, such as RAF aces Robert Stanford Tuck and Douglas Bader. Adolf Galland died in February 1996, Galland was born in Westerholt, Westphalia on 19 March 1912 to a family with French Huguenot ancestry

42nd Infantry Division (United States)
–
The 42nd Infantry Division is a division of the United States Army National Guard. The 42nd Infantry Division has served in World War I, World War II, the division is currently headquartered at the Glenmore Road Armory in Troy, New York. The division headquarters is a unit of the New York Army National Guard, as of 2007,67 percent of 42ID soldiers are located in New York and New Jersey. The 42ID came to be known as the Rainbow Division, when the United States declared war on Germany in 1917, it federalized National Guard divisions to quickly build up an Army. In addition, Douglas MacArthur, then a major, suggested to William A. Mann, the head of the Militia Bureau, that he form another division from the non-divisional units of several states. Secretary of War Newton D. Baker approved the proposal, the division was created using units from 26 states and the District of Columbia. The name stuck, and MacArthur was promoted to colonel as the chief of staff. The 42nd Division adopted a shoulder patch and unit crests acknowledging the nickname, the original version of the patch symbolized a half arc rainbow and contained thin bands in multiple colors. They also reduced the number of colors to just red, gold and blue bordered in green, in order to standardize the design and make the patch easier to reproduce. Description, The 4th quadrant of a rainbow with three bands of color, red, gold and blue, each 3/8 inch in width, outer radius 2 inches, background, The shoulder sleeve insignia was originally authorized by telegram on 29 Oct 1918. It was officially authorized for wear on 27 May 1922 and it was reauthorized for wear when the division was reactivated for World War II. On 8 September 1947 it was authorized for the post-World War II 42nd Infantry Division when it was reactivated as a National Guard unit. The 42nd Division was activated in August 1917, four months after the American entry into World War I, drawing men from 26 states and the District of Columbia. It was composed of the 83rd Infantry Brigade and the 84th Infantry Brigade, together with supporting units such as artillery, engineers, signals and so on. The 42nd went overseas to the Western Front of Belgium and France in November 1917, the AEF was commanded by General John Joseph Pershing. The following year, the took part in four major operations, the Champagne-Marne, the Aisne-Marne, the Battle of Saint-Mihiel. In total, it saw 264 days of combat, while in France, the division was placed under French control for a time, commanded by various French commanders, including Henri Gouraud and Georges de Bazelaire, of the French VII Army Corps. Commanders, Maj. Gen. W. A. Mann, Brig. Gen. Charles T. Menoher, Maj. Gen. Charles D. Rhodes, Brig. Gen. Douglas MacArthur, Maj. Gen. C. A. F. Flagler, Maj. Gen. George Windle Read

Douglas DC-3
–
The Douglas DC-3 is a fixed-wing propeller-driven airliner. Its cruise speed and range revolutionized air transport in the 1930s and 1940s and its lasting effect on the airline industry and World War II makes it one of the most significant transport aircraft ever made. The DC-3 was a twin-engine metal monoplane, developed as a larger and it had many exceptional qualities compared to previous aircraft. It was fast, had a range and could operate from short runways. It was reliable and easy to maintain and carried passengers in greater comfort, before the war it pioneered many air travel routes. Civil DC-3 production ended in 1942 with 607 aircraft being produced, however, together with its military derivative, the C-47 Skytrain, and with Russian- and Japanese-built versions, over 16,000 were built. Following the Second World War, the market was flooded with surplus C-47s and other transport aircraft. While the DC-3 was soon made redundant on main routes by more advanced such as the Douglas DC-6 and Lockheed Constellation. Large numbers continue to see service in a variety of niche roles well into the 21st century. In 2013 it was estimated that approximately 2,000 DC-3s and military derivatives were still flying, the DC-3 was the culmination of a development effort that began after an inquiry from Transcontinental and Western Airlines to Donald Douglas. TWA asked Douglas to design and build an aircraft that would allow TWA to compete with United, Douglas design, the 1933 DC-1, was promising, and led to the DC-2 in 1934. The DC-2 was a success, but there was room for improvement, Douglas agreed to go ahead with development only after Smith informed him of Americans intention to purchase twenty aircraft. The new aircraft was engineered by a led by chief engineer Arthur E. Raymond over the next two years, and the prototype DST first flew on December 17,1935. Its cabin was 92 in wide, and a version with 21 seats instead of the 14–16 sleeping berths of the DST was given the designation DC-3, there was no prototype DC-3, the first DC-3 built followed seven DSTs off the production line and was delivered to American Airlines. The DC-3 and DST popularized air travel in the United States, eastbound transcontinental flights could cross the U. S. in about 15 hours with three refueling stops, westbound trips against the wind took 17 1⁄2 hours. A few years such a trip entailed short hops in slower and shorter-range aircraft during the day. A variety of engines were available for the DC-3. Early-production civilian aircraft used Wright R-1820 Cyclone 9s, but later used the Pratt & Whitney R-1830 Twin Wasp

Pan American World Airways
–
It was also a founding member of the International Air Transport Association, the global airline industry association. Identified by its blue logo, the use of the word Clipper in aircraft names and call signs, and the white pilot uniform caps. In an era dominated by flag carriers that were wholly or majority government-owned, during most of the jet era, Pan Ams flagship terminal was the Worldport located at John F. Kennedy International Airport in New York City. Arnold and Spaatz drew up the prospectus for Pan American when SCADTA hired a company in Delaware to obtain air mail contracts from the U. S. government. Pan American was able to obtain the U. S. mail delivery contract to Cuba and their operation had the all-important landing rights for Havana, having acquired American International Airways, a small airline established in 1926 by John K. Bevier as a service from Key West, Florida, to Havana. ACA met its deadline of having an air service operating by October 19,1927 by chartering a Fairchild FC-2 floatplane from a small Dominican Republic carrier. The Atlantic, Gulf, and Caribbean Airways company was established on October 11,1927 by New York City investment banker Richard Hoyt and this company merged with PAA and ACA on June 23,1928. Richard Hoyt was named as president of the new Aviation Corporation of the Americas, Trippe became operational head of Pan American Airways, the new companys principal operating subsidiary. The government further helped Pan Am by insulating it from its U. S. competitors, the airline expanded internationally, benefiting from a virtual monopoly on foreign routes. Trippe and his associates planned to extend Pan Ams network through all of Central, by the end of the year, Pan Am offered flights along the west coast of South America to Peru. Its Brazilian subsidiary NYRBA do Brasil was later renamed as Panair do Brasil, Pan Am also partnered with Grace Shipping Company in 1929 to form Pan American-Grace Airways, better known as Panagra, to gain a foothold to destinations in South America. The Aviation Corporation of the Americas changed its name to Pan American Airways Corporation in 1931, during the day, use of the compass while judging drift from sea currents was normal procedure, at night, all flight crews were trained to use celestial navigation. In bad weather, pilots used dead reckoning and timed turns, making landings at fogged-in harbors by landing out to sea. Many pilots had merchant marine certifications and radio licenses as well as pilot certificates, before World War II it was not unusual for a captain to make engine repairs at remote locations. Pan Ams mechanics and support staff were similarly trained, newly hired applicants were frequently paired with experienced flight mechanics in several areas of the company until they had achieved proficiency in all aircraft types. Many crews supported repair operations by flying in spare parts to planes stranded overseas, Pan Am started its South American routes with Consolidated Commodore and Sikorsky S-38 flying boats. The S-40, larger than the eight-passenger S-38, began flying for Pan Am in 1931, carrying the nicknames American Clipper, Southern Clipper, and Caribbean Clipper, they were the first of the series of 28 Clippers that symbolized Pan Am between 1931 and 1946
