Eastern Air Lines Flight 663
Eastern Air Lines Flight 663 was a domestic passenger flight from Boston, Massachusetts, to Atlanta, Georgia, with scheduled stopovers at John F. Kennedy International Airport, New York; Richmond, Virginia; Charlotte, North Carolina; and Greenville, South Carolina. On the night of February 8, 1965, the aircraft serving the flight, a Douglas DC-7, crashed near Jones Beach State Park, New York, just after taking off from JFK Airport. All 79 passengers and five crew aboard died. The Civil Aeronautics Board (CAB) investigation determined that evasive maneuvers undertaken by Flight 663 to avoid an oncoming Pan Am Boeing 707 caused the pilot to suffer spatial disorientation and lose control of the aircraft. The accident is the third-worst accident involving a DC-7. Flight history The Douglas DC-7 serving Flight 663 made its first flight in 1958 and subsequently accumulated a total of 18,500 hours of flight time. It was piloted by Captain Frederick R. Carson, 41, who had been employ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas DC-7
The Douglas DC-7 is a retired American transport aircraft built by the Douglas Aircraft Company from 1953 to 1958. A derivative of the DC-6, it was the last major piston engine-powered transport made by Douglas, being developed shortly after the earliest jet airliner—the de Havilland Comet—entered service and only a few years before the jet-powered Douglas DC-8 first flew in 1958. Larger numbers of both DC-7B and DC-7C variants were also built. Unlike other far more successful propeller-driven Douglas aircraft, such as the DC-3 and DC-6, no examples of the DC-7 remain in service as of 2020. Design and development In 1945, Pan American World Airways requested a DC-7, a civil version of the Douglas C-74 Globemaster military transport. Pan Am soon canceled their order. That proposed DC-7 was unrelated to the later DC-6-derived airliner. American Airlines revived the designation when they requested an aircraft that could fly across the United States coast-to-coast non-stop ...

Pan American World Airways
Pan American World Airways, originally founded as Pan American Airways and more commonly known as Pan Am, was an airline that was the principal and largest international air carrier and unofficial overseas flag carrier of the United States for much of the 20th century. The first airline to fly worldwide, it pioneered innovations such as Wide-body aircraft, jumbo jets and computerized reservation systems, and introduced the Boeing 707, first American jetliner in 1958. Until its dissolution on December 4, 1991, Pan Am "epitomized the luxury and glamour of intercontinental travel", and it remains a cultural icon of the 20th century, identified by its blue globe logo ("The Blue Meatball"), the use of the word "Clipper" in its aircraft names and call signs, and the white uniform caps of its pilots. Founded in 1927 by two U.S. Army Air Corps majors, Pan Am began as a scheduled airmail and passenger service flying between Key West, Florida, and Havana, Cuba. In the 1930s, under the le ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Air Canada
Air Canada is the flag carrier and the largest airline of Canada, by size and passengers carried. Air Canada is headquartered in the borough of Saint-Laurent in the city of Montreal. The airline, founded in 1937, provides scheduled and charter air transport for passengers and cargo to 222 destinations worldwide. It operates major hubs at Montréal–Trudeau, Toronto–Pearson and Vancouver. Air Canada is a founding member of the Star Alliance. Canada's national airline originated from the Canadian federal government's 1936 creation of Trans-Canada Air Lines ( TCA), which began operating its first transcontinental flight routes in 1938. In 1965, TCA was renamed Air Canada following government approval. After the deregulation of the Canadian airline market in the 1980s, the airline was privatized in 1988. On 4 January 2000, Air Canada took over its largest rival, Canadian Airlines. In 2003, the airline filed for bankruptcy protection and in the following year emerged ...

Flight Dynamics
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flight, flying through the air or in outer space. It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time. For a fixed-wing aircraft, its changing Orientation (geometry), orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing ("alpha") and the angle of attack of the vertical tail, known as the slip (aerodynamics), sideslip angle ("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, i.e. the centre of gravity moves sideways.Flightwise - Volume 2 - Aircraft Stability And Control, Chris Carpenter 1997, Airlife Publishing Ltd., , p.145 These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft.

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. ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for ...

Eastern Time Zone
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 U.S. states, states in the eastern part of the United States, parts of eastern Canada, and the state of Quintana Roo in Mexico. * Eastern Standard Time (EST) is five hours behind Coordinated Universal Time (UTC−05:00). Observed during standard time (late autumn/winter in the United States and Canada). * Eastern Daylight Time (EDT) is four hours behind Coordinated Universal Time (UTC−04:00). Observed during daylight saving time (spring/summer/early autumn in the United States and Canada). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT, creating a 23-hour day. On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, which results in a 25-hour day. History The boundaries of the Eastern Time Zone have moved westward since the Interstate Commerce Commission (ICC) took over time-zone management from railroads in ...

Flight Engineer
A flight engineer (FE), also sometimes called an air engineer, is a member of an aircraft's flight crew who is responsible for monitoring and operating its complex aircraft systems. In the early era of aviation, the position was sometimes referred to as the "air mechanic". Flight engineers can still be found on some larger Fixed-wing aircraft, fixed-wing airplanes and helicopters. A similar crew position exists on some spacecraft. In most modern aircraft, their complex systems are both monitored and adjusted by electronic microprocessors and computers, resulting in the elimination of the flight engineer's position. In earlier days, most larger aircraft were designed and built with a flight engineer's position. For U.S. civilian aircraft that require a flight engineer as part of the crew, the flight engineer must possess an FAA Flight Engineer Certificate with reciprocating, turboprop, or turbojet ratings appropriate to the aircraft.
