The Sound Barrier
''The Sound Barrier'' is a 1952 British aviation drama film directed by David Lean. It is a fictional story about attempts by aircraft designers and test pilots to break the sound barrier. It was David Lean's third and final film with his wife Ann Todd, but it was his first for Alexander Korda's London Films, following the break-up of Cineguild. ''The Sound Barrier'' stars Ralph Richardson, Ann Todd, John Justin and Nigel Patrick. It was known in the United States as ''Breaking Through the Sound Barrier'' and ''Breaking the Sound Barrier''. ''The Sound Barrier'' was a box-office success on first release, but it has become one of the least-known of Lean's films. Following on ''In Which We Serve'' (1942), the film is another of Lean's ventures into a genre of filmmaking where impressions of documentary film are created. Plot After his aircraft company's groundbreaking work on jet engine technology in the World War II, Second World War, John Ridgefield, its wealthy owner, employs ...

Film Poster
A film poster is a poster used to promote and advertise a film primarily to persuade paying customers into a theater to see it. Studios often print several posters that vary in size and content for various domestic and international markets. They normally contain an image with text. Today's posters often feature printed likenesses of the main actors. Prior to the 1980s, illustrations instead of photos were far more common. The text on film posters usually contains the film title in large lettering and often the names of the main actors. It may also include a tagline, the name of the director, names of characters, the release date, and other pertinent details to inform prospective viewers about the film. Film posters are often displayed inside and on the outside of movie theaters, and elsewhere on the street or in shops. The same images appear in the film exhibitor's pressbook and may also be used on websites, DVD (and historically VHS) packaging, flyers, advertisements in newspap ...

Counterintuitive
A paradox is a logically self-contradictory statement or a statement that runs contrary to one's expectation. It is a statement that, despite apparently valid reasoning from true premises, leads to a seemingly self-contradictory or a logically unacceptable conclusion. A paradox usually involves contradictory-yet-interrelated elements that exist simultaneously and persist over time. They result in "persistent contradiction between interdependent elements" leading to a lasting "unity of opposites". In logic, many paradoxes exist that are known to be invalid arguments, yet are nevertheless valuable in promoting critical thinking, while other paradoxes have revealed errors in definitions that were assumed to be rigorous, and have caused axioms of mathematics and logic to be re-examined. One example is Russell's paradox, which questions whether a "list of all lists that do not contain themselves" would include itself, and showed that attempts to found set theory on the identification ...

Speed Of Sound
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At , the speed of sound in air is about , or one kilometre in or one mile in . It depends strongly on temperature as well as the medium through which a sound wave is propagating. At , the speed of sound in air is about . The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior. In colloquial speech, ''speed of sound'' refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance: typically, sound travels most slowly in gases, faster in liquids, and fastest in solids. For example, while sound travels at in air, it travels at in water (almost 4.3 times as fast) and at in iron (almost 15 times as fast). In an exceptionally stiff material such as diamond, sound travels a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered f ...

De Havilland Comet
The de Havilland DH.106 Comet was the world's first commercial jet airliner. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. Within a year of entering airline service, problems started to emerge, three Comets being lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time; the other was due to overstressing of the airframe during flight through severe weather. The Comet was withdrawn from service and extensively tested. Design and cons ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cairo
Cairo ( ; ar, القاهرة, al-Qāhirah, ) is the capital of Egypt and its largest city, home to 10 million people. It is also part of the largest urban agglomeration in Africa, the Arab world and the Middle East: The Greater Cairo metropolitan area, with a population of 21.9 million, is the 12th-largest in the world by population. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are located in its geographical area. Located near the Nile Delta, the city first developed as Fustat, a settlement founded after the Muslim conquest of Egypt in 640 next to an existing ancient Roman fortress, Babylon. Under the Fatimid dynasty a new city, ''al-Qāhirah'', was founded nearby in 969. It later superseded Fustat as the main urban centre during the Ayyubid and Mamluk periods (12th–16th centuries). Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand m ...

De Havilland Vampire
The de Havilland Vampire is a British jet fighter which was developed and manufactured by the de Havilland, de Havilland Aircraft Company. It was the second jet fighter to be operated by the Royal Air Force, RAF, after the Gloster Meteor, and the first to be powered by a single jet propulsion, jet engine. Development of the Vampire as an experimental aircraft began in 1941 during the Second World War, to exploit the revolutionary innovation of jet propulsion. From the company's design studies, it was decided to use a single-engine, twin-boom aircraft, powered by the de Havilland Goblin, Halford H.1 turbojet (later produced as the Goblin). Aside from its propulsion system and twin-boom configuration, it was a relatively conventional aircraft. In May 1944 it was decided to produce the aircraft as an interceptor aircraft, interceptor for the Royal Air Force (RAF). In 1946 the Vampire entered operational service with the RAF, only months after the war had ended. The Vampire quick ...

Ferry Flying
Ferry flying is the flying of aircraft for the purpose of returning to base, delivery to a customer, moving from one base of operations to another or moving to or from a maintenance facility for maintenance, repair, and operations. A commercial airliner may need to be moved from one airport to another to satisfy the next day's timetable or facilitate routine maintenance; this is commonly known as a positioning flight or repositioning flight, and may carry revenue freight or passengers as local aviation regulations and airline policies allow. They may also be necessary following a major weather event or other similar disruption which causes multiple cancellations across an airline's network resulting in many aircraft and crew being 'out of position' for normal operations; the 2010 eruptions of Eyjafjallajökull or the mass evacuation of US airspace following the 9/11 attacks being significant examples of this.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
