BOAC Flight 911
BOAC Flight 911 (call sign "Speedbird 911") was a round-the-world flight operated by the British Overseas Airways Corporation (BOAC) that crashed near Mount Fuji in Japan on 5 March 1966, with the loss of all 113 passengers and 11 crew members. The Boeing 707 flying the route disintegrated mid-air shortly after departing from Tokyo Haneda Airport as a result of severe clear-air turbulence. The crash of Flight 911 was the third fatal passenger airline accident in Tokyo in a month, following the crash of All Nippon Airways Flight 60 on 4 February and that of Canadian Pacific Air Lines Flight 402 just the day before. Background Aircraft Being manufactured in 1960, the aircraft operating the flight was a 6-year-old Boeing 707-436, registered as G-APFE. It was fitted with 4 Rolls-Royce Conway 508 engines. The aircraft had approximately 19,523 airframe hours. Crew The flight was under the command of Captain Bernard Dobson, aged 45; First Officer Edward Maloney, aged 33; ...

Turbulence
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow, which occurs when a fluid flows in parallel layers with no disruption between those layers. Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason, turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping ...

All Nippon Airways Flight 60
was a Boeing 727-81 aircraft making a domestic commercial flight in Japan from Sapporo Chitose Airport to Tokyo Haneda International Airport. On February 4, 1966, all 133 people on board died when the plane mysteriously crashed into Tokyo Bay about from Haneda in clear weather conditions while on a night approach. The accident was the worst involving a single aircraft in Japan and also the deadliest accident in the country until All Nippon Airways Flight 58 crashed five years later, killing 162 people. Passengers and crew The aircraft carried 126 passengers and a crew of seven. Most of the passengers were returning from the annual Sapporo Snow Festival, north of Tokyo. Accident description Flying in clear weather, ANA Flight 60 was only a few minutes away from Haneda Airport when its pilot radioed he would land visually without instruments. The aircraft then vanished from radar screens. Villagers along the shore and the pilot of another plane said they saw flames i ...

Clear-air Turbulence
In meteorology, clear-air turbulence (CAT) is the turbulence, turbulent movement of air masses in the absence of any visual clues such as clouds, and is caused when bodies of air moving at widely different speeds meet. The atmospheric region most susceptible to CAT is the high troposphere at altitudes of around as it meets the tropopause. Here CAT is most frequently encountered in the regions of jet streams. At lower altitudes it may also occur near mountain ranges. Thin cirrus clouds can also indicate high probability of CAT. CAT can be hazardous to the comfort, and occasionally the safety, of aviation, air travelers, as the aircraft pilots often cannot see and anticipate such turbulences, and a sudden encounter can impart significant stress (mechanics), stress to the airframe. CAT in the jet stream is expected to become stronger and more frequent because of climate change, with transatlantic wintertime CAT increasing by 60% (light), 95% (moderate), and 150% (severe) by the ti ...

Boeing 707
The Boeing 707 is an early American long-range Narrow-body aircraft, narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype, the initial first flew on December 20, 1957. Pan Am began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 is a swept wing four-engined jet aircraft, quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later Boeing 720, 720, Boeing 727, 727, Boeing 737, 737, and Boeing 757, 757 models. Although it was not the first commercial jetliner in service, the 707 was the first to be widespread, and is often credited with beginning the Jet Age. It dominated passenger airline, air-transport in the 1960s, and remained common through the 1970s, on Domestic flight, domestic, Transcontinental flight, transcontinental, and transatlantic flights, as well as cargo and military applications. ...

Speedbird
The Speedbird is the stylised emblem of a bird in flight designed in 1932 by Theyre Lee-Elliott as the corporate logo for Imperial Airways. It became a design classic and was used by the airline and its successors – British Overseas Airways Corporation (BOAC) and British Airways – for 52 years. The term "Speedbird" is still the Aviation call signs, call sign for British Airways. History Imperial Airways The original Speedbird was designed in 1932 for Imperial Airways by Theyre Lee-Elliott through Stuart Advertising Agency. A relief sculpture, which become the final version, was made by Barbara Hepworth. It was initially used on advertising posters and luggage labels.Glenn H. MorganTheyre Lee-Elliott (1903–1988): Graphic Designer, Artist and Writer(retrieved 11 September 2015) Later, it was applied to the nose section of the company's aircraft and could be seen for example in 1938 on the company's Short Empire S.30 flying boats.

Aviation Call Signs
Aviation call signs or aircraft call signs are communication call signs assigned as unique identifiers referring to an aircraft. Call signs in aviation are derived from several different policies, depending upon the type of flight operation and whether or not the caller is in an aircraft or at a ground facility. In most countries, unscheduled general aviation flights identify themselves using the call sign corresponding to the aircraft's registration number (also called ''N-number'' in the U.S., or ''tail number''). In this case, the call sign is spoken using the International Civil Aviation Organization (ICAO) phonetic alphabet. Aircraft registration numbers internationally follow the pattern of a country prefix, followed by a unique identifier made up of letters and numbers. For example, an aircraft registered as ''N978CP'' conducting a general aviation flight would use the call sign ''November-niner-seven-eight-Charlie-Papa''. However, in the United States a pilot of an aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Hong Kong
Hong Kong was under British Empire, British rule from 1841 to 1997, except for a Japanese occupation of Hong Kong, brief period of Japanese occupation during World War II from 1941 to 1945. It was a crown colony of the United Kingdom from 1841 to 1981, and a British Dependent Territory, dependent territory from 1981 to 1997. The colonial period began with the British occupation of Hong Kong Island under the Convention of Chuenpi in 1841 of the Victorian era, and ended with the handover of Hong Kong to the China, People's Republic of China in July 1997. In accordance with Art. III of the Treaty of Nanking of 1842, signed in the aftermath of the First Opium War, the island of Hong Kong was ceded in perpetuity to Great Britain. It was established as a Crown colony in 1843. In 1860, the British expanded the colony with the addition of the Kowloon Peninsula and was further extended in 1898 when the British obtained Convention for the Extension of Hong Kong Territory, a 99-year lease ...

Kai Tak Airport
Kai Tak Airport was an international airport of Hong Kong from 1925 until 1998. Officially known as Hong Kong International Airport from 1954 to 6 July 1998, it is often referred to as Hong Kong International Airport, Kai Tak, or simply Kai Tak and Kai Tak International Airport, to distinguish it from its successor, Chek Lap Kok International Airport, built on reclaimed and levelled land around the islands of Chek Lap Kok and Lam Chau, to the west. Because of the geography of the area, with water on three sides of the runway, Kowloon City's residential apartment complexes to the north-west and mountains more than high to the north-east of the airport, aircraft could not fly over the mountains and quickly drop in for a final approach. Instead, aircraft had to fly above Victoria Harbour and Kowloon City, passing north of Mong Kok's Bishop Hill. After passing Bishop Hill, pilots would see Checkerboard Hill with a large orange-and-white checkerboard pattern. Once the pat ...
