Context: The Steven F. Udvar-Hazy Center, also called the Udvar-Hazy Center, is the Smithsonian National Air and Space Museum (NASM)'s annex at Washington Dulles International Airport in the Chantilly area of Fairfax County, Virginia, United States., Giuseppe Mario Bellanca ( March 19 , 1886 -- December 26 , 1960 ) was an Italian - American airplane designer and builder who created the first enclosed cabin monoplane in the United States in 1922 . This aircraft is now on display at the National Air and Space Museum 's Steven F. Udvar - Hazy Center ., A monoplane is a fixed-wing aircraft with a single main wing plane, in contrast to a biplane or other multiplane, each of which has multiple planes., The Smithsonian Institution, established in 1846 "for the increase and diffusion of knowledge," is a group of museums and research centers administered by the Government of the United States. Originally organized as the "United States National Museum," that name ceased to exist as an administrative entity in 1967.
Termed "the nation's attic"
for its eclectic holdings of 138 million items, the Institution's nineteen museums, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Arizona, Maryland, Massachusetts, New York City, Virginia, Texas, and Panama. More than 200 institutions and museums in 45 states, Puerto Rico, and Panama are Smithsonian Affiliates
The Institution's thirty million annual visitors are admitted without charge.
The institution's annual budget is around $1.2 billion with 2/3 coming from annual federal appropriations. Other funding comes from the Institution's endowment, private and corporate contributions, membership dues, and earned retail, concession, and licensing revenue. Institution publications include "Smithsonian" and "Air & Space" magazines., A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s., The National Air and Space Museum of the Smithsonian Institution, also called the NASM, is a museum in Washington, D.C.. It holds the largest collection of historic aircraft and spacecraft in the world. It was established in 1946 as the National Air Museum and opened its main building on the National Mall near L'Enfant Plaza in 1976. In 2014, the museum saw approximately 6.7 million visitors, making it the fifth most visited museum in the world. The museum contains the Apollo 11 module, the Friendship 7 which was flown by John Glenn, the Bell X-1 which broke the sound barrier, and the Wright brothers plane near the entrance. , L'Enfant Plaza is a complex of four commercial buildings grouped around a large plaza in the Southwest section of Washington, D.C.. Immediately below the plaza and the buildings is the "La Promenade" shopping mall. The plaza is located south of Independence Avenue SW between 12th and 9th Streets SW (9th Street actually runs underneath the centers of the buildings on the easternmost side of the plaza). It was built perpendicular to L'Enfant Promenade, a north-south running street and pedestrian esplanade part of which is directly above 10th Street SW. The plaza is named for Pierre (Peter) Charles L'Enfant, the architect and planner who first designed a street layout for the capital city. It was dedicated in 1968 after completion of the north and south buildings., Washington Dulles International Airport is an international airport in Loudoun and Fairfax counties in Virginia, United States, 26 miles (42 km) west of downtown Washington, D.C. The airport serves the BaltimoreWashington Metropolitan Area, centered on the District of Columbia. The airport is named after John Foster Dulles, the 52nd Secretary of State who served under President Dwight D. Eisenhower. The Dulles main terminal is a well-known landmark designed by Eero Saarinen. Operated by the Metropolitan Washington Airports Authority, Dulles Airport occupies 13,000 acres (52.6 km) straddling the Loudoun-Fairfax line. Most of the airport is in the unincorporated community of Dulles, in Loudoun County, with a small portion in the unincorporated community of Chantilly in Fairfax County., John Herschel Glenn Jr. (July 18, 1921  December 8, 2016) was a United States Marine Corps aviator, engineer, astronaut, and United States Senator from Ohio. In 1962 he was the first American to orbit the Earth, circling it three times. Before joining NASA, Glenn was a distinguished fighter pilot in World War II and Korea with six Distinguished Flying Crosses and eighteen clusters on his Air Medal., The Bell X-1 was a rocket engine-powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics-U.S. Army Air Forces-U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time, exceeded in 1954. The X-1, piloted by Chuck Yeager, was the first manned airplane to exceed the speed of sound in level flight and was the first of the X-planes, a series of American experimental rocket planes (and non-rocket planes) designated for testing of new technologies and often kept secret., The National Mall is a national park in downtown Washington, D.C., the capital of the United States. The National Park Service (NPS) administers the National Mall, which is part of its National Mall and Memorial Parks unit. The term "National Mall" commonly includes areas that are officially part of West Potomac Park and Constitution Gardens to the west, and often is taken to refer to the entire area between the Lincoln Memorial and the United States Capitol, with the Washington Monument dividing the area slightly west of its midpoint. A smaller designation, sometimes referred to as the "Mall proper", excludes both the Capitol grounds and the Washington Monument grounds, applying only to an area between them. The National Mall contains a number of museums and memorials and receives approximately 24 million visitors each year., The Wright brothers, Orville (August 19, 1871  January 30, 1948) and Wilbur (April 16, 1867  May 30, 1912), were two American brothers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south of Kitty Hawk, North Carolina. In 190405 the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible., Subject: giuseppe mario bellanca, Relation: occupation, Options: (A) army (B) astronaut (C) aviation (D) aviator (E) commercial (F) national park service (G) research (H) secretary (I) secretary of state (J) united states marine corps
