Information: - To Fly ! ( 1976 ) is a documentary film shot in the IMAX format . It follows the history of flight , from the first hot air balloons in the 19th century to 20th century manned space missions . It was created for performance at the National Air and Space Museum 's IMAX Theater in Washington , D.C. - Film stock is an analog medium that is used for recording motion pictures or animation. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to X-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into the infrared (IR) region of the spectrum. - 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. - 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 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. - A spacecraft is a vehicle, or machine designed to fly in outer space. Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. - Apollo 11 was the spaceflight that landed the first two humans, who were Americans, on the Moon. Mission commander Neil Armstrong and pilot Buzz Aldrin landed the lunar module "Eagle" on July 20, 1969, at 20:18 UTC. Armstrong became the first to step onto the lunar surface six hours later on July 21 at 02:56:15 UTC; Aldrin joined him about 20 minutes later. They spent about two and a quarter hours together outside the spacecraft, and collected of lunar material to bring back to Earth. Michael Collins piloted the command module "Columbia" alone in lunar orbit while they were on the Moon's surface. Armstrong and Aldrin spent just under a day on the lunar surface before rendezvousing with "Columbia" in lunar orbit. - 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. - Roman Kroitor (December 12, 1926 September 17, 2012) was a Canadian filmmaker who was known as an early practitioner of Cinema verite, as co-founder of IMAX, and as creator of the Sandde hand-drawn stereoscopic animation system. He was also the original inspiration for the Force, popularized in the "Star Wars" series. - 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. - IMAX (an acronym for Image maximum) is a motion picture film format and a set of cinema projection standards developed in Canada by Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw. IMAX has the capacity to record and display images of far greater size and resolution than conventional film systems. Since 2002, some feature films have been converted (or upgraded) into IMAX format for displaying in IMAX theatres and some have also been partially shot in IMAX. - 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 documentary film is a nonfictional motion picture intended to some aspect of reality, primarily for the purposes of instruction, education, or maintaining a historical record. Such films were originally shot on film stockthe only medium availablebut now include video and digital productions that can be either direct-to-video, made into a TV show, or released for screening in cinemas. "Documentary" has been described as a "filmmaking practice, a cinematic tradition, and mode of audience reception" that is continually evolving and is without clear boundaries. - Direct-to-video or straight-to-video (also known as direct-to-VHS, direct-to-DVD, direct-to-Blu-ray, direct-to-digital, etc.) refers to the release of a film to the public immediately on home video formats rather than a theatrical release or television broadcast. Because inferior sequels or prequels of larger-budget films may be released direct to video, references to direct-to-video releases are often pejorative. Direct-to-video release has also become profitable for independent filmmakers and smaller companies. - A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film, for either stills or filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape. - Ivan Graeme Ferguson, CM (born 7 October 1929 in Toronto, Ontario) is a Canadian filmmaker and inventor who co-invented IMAX. Ferguson was appointed a Member of the Order of Canada in 1993. He graduated from the University of Toronto with a bachelor's degree. - 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.
