12096-460: The 213A (the major production version), the 213E (a high-altitude model), and the projected 213J (improved still more). The Mission visited Nordhausen (the Mittelwerk ) 19 June, some by DC-3 Dakota, some by Jeep. There, they first came in contact with concentration camps (among which Nordhausen was not officially counted). Nevertheless, Mission members found themselves revolted. With the handover to

12264-463: The 801; Soestmeyer reported RLM had intended to build similar facilities at the central Luftwaffe test station, or Erprobungsstelle at Rechlin , and in Berlin , Dessau, and Stuttgart. The test facility was a building 250 ft (76 m) square and 70 ft (21 m) high, containing a steel cylindrical altitude chamber some 12 ft (3.7 m) in diameter and 30 ft (9.1 m) long, with

12432-631: The American West have an alpine climate . The climate is arid in the Southwest, Mediterranean in coastal California , and oceanic in coastal Oregon , Washington , and southern Alaska . Most of Alaska is subarctic or polar . Hawaii , the southern tip of Florida and U.S. territories in the Caribbean and Pacific are tropical . States bordering the Gulf of Mexico are prone to hurricanes, and most of

12600-582: The Americans, which came to nearer 2,000 tons. Unable to get the Herbitus test stand moved to Britain, and though Operation Surgeon had identified some desired 1,500 specialists to be brought to Britain (forcibly, if need be), Fedden had no better luck persuading His Majesty's Government to bring back German engineers and scientists, which both the Soviets (under Operation Osoaviakhim ) and Americans (Operation Overcast, later called Operation Paperclip ) were doing. In

12768-583: The BMW high-altitude test chamber at Munich, as well as German facilities at Stuttgart, Göttingen, Volkenrode, and Kochel, in order to gather more information on German turbine manufacture and to witness the testing of the Goblin on the Munich testbed. The BMW facility, codenamed Herbitus, was designed and operated by Christoph Soestmeyer, and was finished in May 1944. It was used for trials on BMW and Jumo turbine engines, as well as

12936-542: The Bavarian Alps, where a Bell Aircraft team had already been working some five weeks; there was also a representative from de Havilland . Messerschmitt had taken over a former Heer barracks in 1943, and constructed 22 mi (35 km) of tunnels. The works there were a taste of the future, and Fedden interviewed a number of Messerschmitt's senior engineers, including Hans Hornung, Joseph Helmschrott, and chief designer Waldemar Voigt . The Mission were shown examples of

13104-502: The BraWo Park's parking lot is today, held about 800 male prisoners, who were forced to work in the arms production at Büssing-NAG . After about 300 had died due to disease, hunger, and maltreatment over the course of just a few months, a further 200 were transferred to the infirmary of a nearby subcamp in early January 1945 in order to reduce the number of deaths. However, this was only effective to some degree, as another 80 bodies landed in

13272-714: The British (including an interferometer ), only to have the thefts denied when confronted by Britain at Potsdam . The Fedden Mission spent two days at Völkenrode, its sub-team returning ten days later. The Mission left Braunschweig airfield 19.15 on Friday, 15 June for Kassel, 80 mi (130 km) away (where the Henschel firm's aviation division was based); next morning, one group went to Göttingen to interrogate Dr. Ludwig Prandtl and his team; Fedden called them "a first class team of experimental research workers". While in Göttingen, Mission members examined more than ten wind tunnels on

13440-474: The Declaration of Independence on July 4, 1776. The term "United States" and the initialism "U.S.", used as nouns or as adjectives in English, are common short names for the country. The initialism "USA", a noun, is also common. "United States" and "U.S." are the established terms throughout the U.S. federal government , with prescribed rules. In English, the term "America" rarely refers to topics unrelated to

13608-662: The District of Columbia occupy a combined area of 3,119,885 square miles (8,080,470 km ). The coastal plain of the Atlantic seaboard gives way to inland forests and rolling hills in the Piedmont plateau region. The Appalachian Mountains and the Adirondack massif separate the East Coast from the Great Lakes and the grasslands of the Midwest . The Mississippi River System ,

13776-613: The Elder concluded that major military resources needed to be devoted to North America to win the war against France. For the first time, the continent became one of the main theaters of what could be termed a " world war ". The British colonies' position as an integral part of the British Empire became more apparent during the war, with British military and civilian officials becoming a more significant presence in American life. The war increased

13944-663: The Fedden Mission travelled from Eisenach to Klobermoor, location of the Heinkel - Hirth engine works. There, they examined copies of the Heinkel HeS 011 jet engine, one of Germany's finest and most advanced turbine engines of the period, of which only 19 development and test examples were ever completed. The Mission conducted extensive interviews with the managing director, Mr. Schaaf, and the senior planning engineer, Mr. Dorls, as well as Hartkopf, comparing piston and jet engine production;

14112-662: The January 1863 Emancipation Proclamation , many freed slaves joined the Union army . The war began to turn in the Union's favor following the 1863 Siege of Vicksburg and Battle of Gettysburg , and the Confederacy surrendered in 1865 after the Union's victory in the Battle of Appomattox Court House . The Reconstruction era followed the war. After the assassination of President Abraham Lincoln , Reconstruction Amendments were passed to protect

14280-557: The Lion of the House of Welf became duke of Saxony and made Braunschweig the capital of his state (which, from 1156 on, also included the Duchy of Bavaria ). He turned Dankwarderode Castle, the residence of the counts of Brunswick , into his own Pfalz and developed the city further to represent his authority. Under Henry's rule, the Cathedral of St. Blasius was built and he also had the statue of

14448-640: The Lionheart . However, Henry's son Otto , who regained influence and was eventually crowned Holy Roman Emperor , continued to foster the city's development. During the Middle Ages , Brunswick was an important center of trade, one of the economic and political centers in Northern Europe and a member of the Hanseatic League from the 13th century to the middle of the 17th century. By the year 1600, Brunswick

14616-581: The Me 262, with Voigt blaming inexperience among pilots, and compressor stalls, for several accidents. They also saw a variety of projected designs, including the P.1101 (the only one prototyped), P.1110 , P.1112 ,. and P.1108 (which Fedden, apparently, mis-identifies as the PL.08.01). The Fedden Mission, throughout its time in Germany, encountered the destructive effects of bombing. Indeed, on its first day in Germany, it could scarcely navigate through Braunschweig . Many of

14784-424: The Mission compiled a table of comparative cost of materials, finding jets were between one half and two-thirds as costly, as well as being simpler and requiring lower-skill labor and less sophisticated tooling; in fact, most of making of hollow turbine blades and sheet metal work on jets could be done by tooling used in making automobile body panels . While Fedden was critical of some of the German design decisions,

14952-484: The Mission estimated German jet engine production by mid-1946 would have been at a rate of at least 100,000 a year. The Mission was told the overhaul cycle for the Jumo 004 was between thirty and fifty hours (and about fifty for the BMW 003), and approximately 300 Jumo 004 engines had been rebuilt, some more than once. Between Wednesday, 20 June and the following Sunday (24 June), the Mission ( billetted overnight 20–21 June at

15120-456: The Mission examined a BMW facility near Staßfurt, set up in a former salt mine 400 m (1,300 ft) underground, which was to have used for machining jet engine parts, and possibly for assembly, also; Stoffergen said 1,700 machine tools had been installed, and some 2,000 workers had been employed. The Mission also found some information on the high-thrust (designed for a 34.3 kN (7,700 lbf) top output level) BMW 018 jet engine project, which

15288-445: The Mission found examples of Otto Lutz 's swing-piston engine , developed co-operatively with Bussing of Braunschweig , with work also done by Mahle and Bosch . Fedden was dismissive. By contrast, he praised German use of wind tunnels in engine development, and suggested fuel injection was increasingly important for piston engines, especially as the number of cylinders rose. The Mission's examination of fuel injection research

15456-584: The Mission nevertheless found contradictions between his briefing before departure and what his interviews with the company's general manager, Mr. Haspel, and chief designer, Dr. Schmidt, told him. The Mission was informed development of the 24-cylinder Daimler-Benz DB 604 single-crankcase X engine had been stopped in 1940 by the RLM and had finally been abandoned by Daimler-Benz in September 1942; Daimler-Benz had considered 36-cylinder engines, as well.> At Völkenrode,

15624-411: The Mission returned to Britain on 1 July 1945, just Stern and Beeton remaining. 4 July, they arranged for the Mission to see BMW's high-altitude engine test bench in Munich, which Fedden and three others did 17 July, as part of an eight-day trip. A sub-group of the Mission, with some further British aeronautical design engineers, returned to Germany from 16–25 July 1945, working out of Freising, to examine

15792-518: The Mission's Jeeps , which they soon learned to unload and have on the road in only ten minutes. Everywhere the Mission went, it encountered looting by Allied troops and German civilians, and sabotage by German factory workers and the Heer (on Hitler's orders) The German scientists and technicians were, in general, very co-operative with the British interviewers, with Fedden mentioning "considerable apprehension" about their fate and some wishing to emigrate to

15960-595: The Rocky Mountains, the Yellowstone Caldera , is the continent's largest volcanic feature. In 2021, the United States had 8% of global permanent meadows and pastures and 10% of cropland. With its large size and geographic variety, the United States includes most climate types. East of the 100th meridian , the climate ranges from humid continental in the north to humid subtropical in the south. The western Great Plains are semi-arid . Many mountainous areas of

16128-504: The Soviets only two days away, the Mission had little time to explore, and there was no well-informed guide. They found hundreds of incomplete V-1s , and many spare parts for the V-2 , even after the U.S. had spent the ten weeks since the factory was discovered stripping it before turning it over to the Soviets; as much as three hundred railcar-loads worth of material may have been removed, in addition to numerous complete V-2s. On Thursday, 21 June,

16296-490: The Third U.S. Army's Intelligence Center, examined BMW's plant at Munich and interviewed Dr. Bruckmann, Fedden's old friend, technical director of BMW's engine programs; Dr. Amman, in charge of BMW's piston engine development; Mr. Willich, his top aide; and Dr. Sachse, senior engineer until 1942, and the man responsible for overseeing production of the 801 radial. While at Munich, the Mission examined several 801 developments, including

16464-625: The U.S. has become a key ally of Ukraine ; it has also provided the country with significant military equipment and other support in response to Russia's 2022 invasion . The president is the commander-in-chief of the United States Armed Forces and appoints its leaders, the secretary of defense and the Joint Chiefs of Staff . The Department of Defense , which is headquartered at the Pentagon near Washington, D.C., administers five of

16632-990: The U.S. or Canada. (They had genuine concern about forced emigration to the Soviet Union, as many of the V-2 program scientists suffered.) The Mission particularly criticized the RLM for its starting and stopping of engine production programs . The Mission left RAF Northolt on Tuesday, 12 June 1945 at 14.15, bound for Bückeburg , Germany, 25 mi (40 km) southwest of Hannover . They reached Bückeburg at 16.30 and were immediately sent on to another airfield; they eventually reached Bad Eilsen , headquarters of Second Tactical Air Force , at 21.30. From there, they were driven to 21st Army Group . headquarters at Bad Oeynhausen, where they spent their first night. Wing Commander Cross, by proposing one aircraft fly ahead to arrange accommodations, permits for interviews, travel permits for interview subjects, and so on, made an important contribution to

16800-661: The U.S. territories." Despite disparate systems of confinement, four main institutions dominate: federal prisons , state prisons , local jails, and juvenile correctional facilities . Federal prisons are run by the Federal Bureau of Prisons and hold people who have been convicted of federal crimes, including pretrial detainees. State prisons, run by the official department of correction of each state, hold sentenced people serving prison time (usually longer than one year) for felony offenses. Local jails are county or municipal facilities that incarcerate defendants prior to trial; they also hold those serving short sentences (typically under

16968-461: The United States and the peaceful transfer of power , respectively. The Louisiana Purchase of 1803 from France nearly doubled the territory of the United States. Lingering issues with Britain remained , leading to the War of 1812 , which was fought to a draw. Spain ceded Florida and its Gulf Coast territory in 1819. In the late 18th century, American settlers began to expand westward , many with

17136-748: The United States entered the Cold War, where geopolitical tensions between the U.S. and the Soviet Union led the two countries to dominate world affairs . The U.S. utilized the policy of containment to limit the USSR's sphere of influence, and prevailed in the Space Race , which culminated with the first crewed Moon landing in 1969. Domestically, the U.S. experienced economic growth , urbanization , and population growth following World War II . The civil rights movement emerged, with Martin Luther King Jr. becoming

17304-649: The United States has operated as a de facto two-party system , though the parties in that system have been different at different times. The two main national parties are presently the Democratic and the Republican . The former is perceived as relatively liberal in its political platform while the latter is perceived as relatively conservative . In the American federal system , sovereign powers are shared between two levels of elected government: national and state. People in

17472-572: The United States in 2001 by the pan-Islamist militant organization al-Qaeda led to the war on terror , and subsequent military interventions in Afghanistan and Iraq . The cultural impact of the attacks was profound and long-lasting. The U.S. housing bubble culminated in 2007 with the Great Recession , the largest economic contraction since the Great Depression. Coming to a head in

17640-631: The United States of America to Spain" to seek assistance in the Revolutionary War effort. The first known public usage is an anonymous essay published in the Williamsburg newspaper, The Virginia Gazette , on April 6, 1776. By June 1776, the "United States of America" appeared in the Articles of Confederation and the Declaration of Independence . The Second Continental Congress adopted

17808-580: The United States, despite the usage of "the Americas " as the totality of North and South America. "The States" is an established colloquial shortening of the name, used particularly from abroad; "stateside" is the corresponding adjective or adverb. The first inhabitants of North America migrated from Siberia across the Bering land bridge about 12,000 years ago; the Clovis culture , which appeared around 11,000 BC,

17976-605: The United States, except Iran , North Korea , and Bhutan . Though Taiwan does not have formal diplomatic relations with the U.S., it maintains close unofficial relations. The United States regularly supplies Taiwan with military equipment to deter potential Chinese aggression. Its geopolitical attention also turned to the Indo-Pacific when the United States joined the Quadrilateral Security Dialogue with Australia, India, and Japan. The United States has

18144-509: The United States. The American prison system is largely heterogenous, with thousands of relatively independent systems operating across federal, state, local, and tribal levels. In 2023, "these systems [held] almost 2 million people in 1,566 state prisons, 98 federal prisons, 3,116 local jails, 1,323 juvenile correctional facilities, 181 immigration detention facilities, and 80 Indian country jails, as well as in military prisons , civil commitment centers, state psychiatric hospitals, and prisons in

18312-856: The acquiescence of the state government. After the Nazi seizure of power in 1933, several state institutions were placed in Braunschweig, including the Luftfahrtforschungsanstalt in Völkenrode , the Hitler Youth Academy for Youth Leadership , and the SS - Junkerschule Braunschweig . With the Reichswerke Hermann Göring in Salzgitter and the Stadt des KdF-Wagens , as well as several factories in

18480-403: The bad economic situation. During the night of 7–8 September 1830, the ducal palace in Brunswick was stormed by an angry mob, set on fire, and destroyed completely. Charles was succeeded by his brother William VIII . During William's reign, liberal reforms were made and Brunswick's parliament was strengthened. During the 19th century, industrialisation caused a rapid growth of population in

18648-552: The campus, plus several used for fluid dynamics studies. They spent 17 June in Göttingen, also. The same day, the second Mission group flew to Oschersleben (the home of AGO , a major Fw 190A subcontractor) then drove by Jeep to the Junkers jet engine plant at Magdeburg. They had little time before it, and all the surrounding territory, was handed over to the Soviets. The Junkers works, used for manufacturing and overhaul of Jumo 004 jet engines, had been heavily bombed; while there were

18816-592: The city itself (including Büssing and the Volkswagenwerk Braunschweig ), the Braunschweig region became one of the centres of the German arms industry . During the Second World War , Braunschweig was a sub-area headquarters of Wehrkreis XI (one of Germany's military districts), and was the garrison city of the 31st Infantry Division that took part in the invasions of Poland, Belgium, and France, largely being destroyed during its retreat following

18984-616: The city's crematory until the subcamp's closing in March 1945, when Büssing-NAG had to halt production due to severe bombing damages. Today the Gedenkstätte Schillstraße , located very close to the former premises of the subcamp, documents Braunschweig's history during the Third Reich . Büssing-NAG also had another subcamp in the nearby Vechelde , which held a further 400 male prisoners. The subcamp SS-Reitschule , named so as it

19152-600: The city, eventually causing Brunswick to be for the first time significantly enlarged beyond its medieval fortifications and the River Oker. On 1 December 1838, the first section of the Brunswick–Bad Harzburg railway line connecting Brunswick and Wolfenbüttel opened as the first railway line in Northern Germany, operated by the Duchy of Brunswick State Railway . On 8 November 1918, at the end of World War I ,

19320-577: The city. Emilia Galotti by Lessing and Goethe 's Faust were performed for the first time in Brunswick. In 1806, the city was captured by the French during the Napoleonic Wars and became part of the short-lived Napoleonic Kingdom of Westphalia in 1807. The exiled Duke Frederick William raised a volunteer corps, the Black Brunswickers , who fought the French in several battles. After

At an elevation of 20,310 feet (6,190.5 m), Alaska's Denali is the highest peak in the country and continent. Active volcanoes are common throughout Alaska's Alexander and Aleutian Islands , and Hawaii consists of volcanic islands. The supervolcano underlying Yellowstone National Park in

19656-549: The country's GDP. The U.S. has 42% of the world's nuclear weapons —the second-largest share after Russia. The United States has the third-largest combined armed forces in the world, behind the Chinese People's Liberation Army and Indian Armed Forces . The military operates about 800 bases and facilities abroad, and maintains deployments greater than 100 active duty personnel in 25 foreign countries. State defense forces (SDFs) are military units that operate under

19824-464: The country's territory would expand with the admission of new states , rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles. It went into effect in 1789, creating a federal republic governed by three separate branches that together ensured a system of checks and balances . George Washington

19992-647: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty . For a century, the American colonists had been providing their own troops and materiel in conflicts with indigenous peoples allied with Britain's colonial rivals , especially France, and the Americans had begun to develop a sense of self-defense and self-reliance separate from Britain. The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt

20160-474: The dispossession of native inhabitants . As more states were admitted , a North–South division over slavery led to the secession of the Confederate States of America , which fought states remaining in the Union in the 1861–1865 American Civil War . With the victory and preservation of the United States, slavery was abolished nationally . By 1900, the country had established itself as a great power ,

20328-564: The environment for labor unions to begin to flourish . This period eventually ended with the advent of the Progressive Era , which was characterized by significant reforms. Pro-American elements in Hawaii overthrew the Hawaiian monarchy ; the islands were annexed in 1898. That same year, Puerto Rico , the Philippines , and Guam were ceded to the U.S. by Spain after the latter's defeat in

20496-433: The event, only about 100 leaving Germany in 1946 and 1947 actually stayed in Britain. The Soviets moved "between 10,000 and 15,000". So many were taken by both the U.S. and the Soviet Union, the space program's running joke was, "Let's see if their Germans are better than our Germans." The Fedden Mission issued a final report in summer 1945. United States The United States of America ( USA ), commonly known as

20664-456: The factories they had hoped to visit, including Daimler-Benz's in Untertürkheim (Stuttgart), Junkers' at Dessau, BMW's in Staßfurt, Bosch's in Stuttgart, and Junkers Jumo's at Magdeburg, were in ruins — the twin Junkers facilities and the Staßfurt facility for BMW were to end up in the Soviet Zone of Occupation in a very short time. Yet many interview subjects reported Allied bombing of German communications, including railyards, trains, and roads,

20832-414: The federal government often applied policies of Indian removal or assimilation . The Trail of Tears (1830–1850) was a U.S. government policy that forcibly removed and displaced most Native Americans living east of the Mississippi River to lands far to the west. These and earlier organized displacements prompted a long series of American Indian Wars west of the Mississippi. The Republic of Texas

21000-434: The first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945, ending the war. The United States was one of the " Four Policemen " who met to plan the post-war world , alongside the United Kingdom , Soviet Union , and China . The U.S. emerged relatively unscathed from the war, with even greater economic power and international political influence . After World War II,

21168-411: The first settlement of the Thirteen Colonies in Virginia in 1607. Clashes with the British Crown over taxation and political representation sparked the American Revolution , with the Second Continental Congress formally declaring independence on July 4, 1776. Following its victory in the 1775–1783 Revolutionary War , the country continued to expand westward across North America , resulting in

21336-420: The former district was incorporated into the city of Braunschweig, increasing its population by roughly 52,000 people. In the 1990s, efforts increased to reconstruct historic buildings that had been destroyed in the air raid. The façade of the Braunschweiger Schloss was rebuilt, and buildings such as the Alte Waage (originally built in 1534) now stand again. Braunschweig has a population of 250,000 and

21504-463: The integration of Army National Guard units and personnel into the U.S. Army and (since 1947) the U.S. Air Force. There are about 18,000 U.S. police agencies from local to national level in the United States. Law in the United States is mainly enforced by local police departments and sheriff departments in their municipal or county jurisdictions. The state police departments have authority in their respective state , and federal agencies such as

21672-459: The interior, the NSDAP organized a large SA rally in Braunschweig. On 17–18 October 1931, 100,000 SA stormtroopers marched through the city; street fights between Nazis, socialists, and communists left several dead or injured. On 25 February 1932, the state of Brunswick granted Adolf Hitler German citizenship to allow him to run in the 1932 German presidential election . In Braunschweig, Nazis carried out several attacks on political enemies, with

21840-460: The invasion of Russia. In this period, thousands of Eastern workers were brought to the city as forced labor , and in the 1943–1945 period at least 360 children taken away from such workers died in the Entbindungsheim für Ostarbeiterinnen ("Maternity Ward for Eastern Workers"). In 1944, two subcamps of the Neuengamme concentration camp were established in Braunschweig. The subcamp Schillstraße or Büssing-NAG/Schillstraße , located where

22008-409: The largest Vietnamese, Cameroonian and Tunisian populations in Germany are located in the surroundings and within Braunschweig. These are the biggest nationalities in the urban area ( these include the citizens with a migration background and a second passport ): Braunschweig's climate is classified as oceanic ( Köppen : Cfb ; Trewartha : Dobk ). The average annual temperature in Braunschweig

22176-561: The largest minority groups, including citizens with a migration background from a specific nation or region: The estimated migration population in 2025 is 95,961 (35% of 274,233). The urban agglomeration area of Braunschweig is approximately 400,000 in 2024, making it one of the largest regiopolis after Mannheim and Bonn in Germany and the largest one in Lower Saxony . This area includes Wolfenbüttel , Meine , Salzgitter-Thiede , Salzgitter-Lebenstedt , Weddel , Sickte , Timmerlah , Lengede and other towns and regions within

22344-427: The military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw

22512-612: The most attractive to the population are the most vulnerable. The U.S. is one of 17 megadiverse countries containing large numbers of endemic species : about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 birds, 311 reptiles, 295 amphibians , and around 91,000 insect species. There are 63 national parks , and hundreds of other federally managed parks, forests, and wilderness areas , managed by

22680-399: The most important places and streets, preserved in 5 areas of the old town. The city's cathedral, which had been converted to a Nationale Weihestätte (national shrine) by the Nazi government, still stood. About 10% of the inner city survived Allied bombing and remain to represent its distinctive architecture. The cathedral was restored to its function as a Protestant church. Outside

22848-478: The most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created. During the colonial period, slavery had been legal in the American colonies , though the practice began to be significantly questioned during the American Revolution. States in the North enacted abolition laws , though support for slavery strengthened in Southern states , as inventions such as

23016-468: The old town city centre large historic quarters remain like Östliches Ringgebiet with its Gründerzeit architecture. Politically, after the war, the Free State of Brunswick was dissolved by the Allied occupying authorities , Braunschweig ceased to be a capital, and most of its lands were incorporated in the newly formed state of Lower Saxony . During the Cold War , Braunschweig, then part of West Germany , suffered economically due to its proximity to

While in Germany, the team also returned to the enormous research station at Volkenrode, to Stuttgart, Göttingen, and Kochel, and on a day off (22 July 1945) visited Salzburg and Berchtesgaden in the Dakota. The Mission returned to Britain with a Volkswagen on board, as well as a number of jet engines and rocket motors, turbine blades, and "a large quantity of drawings", yet much less than

23352-408: The policy of redlining later adopted by the federal Home Owners' Loan Corporation . An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries , allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by

Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California, Nevada, Utah, and much of present-day Colorado and the American Southwest . The California gold rush of 1848–1849 spurred a huge migration of white settlers to the Pacific coast, leading to even more confrontations with Native populations. One of

26376-438: Was (despite being in the British Zone) effectively in U.S. hands. At Völkenrode, the Mission examined the wind tunnels. These had been used to develop the swept wing , the forward-swept wing , the Messerschmitt Me 262 , the BMW-designed cowlings used for all versions of the BMW 801 radial (used in the Focke-Wulf Fw 190 and a number of other important German military aircraft designs, especially in unitized engine formats),

They got better information on German aircraft spark plugs , from BMW, Daimler, and Bosch, but not from Beru or Siemens, finding, in general, improvements focused on better performance at altitude or hotter, usually with better insulators or cooling. Investigation of propellers found new research had been halted when RLM decided to focus on jets, only to be resumed. The Mission's interviews were limited to Vereinigte Deutsche Metallwerke (United German Metalworks, VDM), and, at Göttingen, they interviewed Dr. Stüper, who tested VDM's reversible propeller. This three-bladed unit had links to two electric motors, which could change
