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. ...

2019 Saha Airlines Boeing 707 Crash
On 14 January 2019, a Boeing 707 operated by Saha Airlines on a cargo flight crashed at Fath Air Base, near Karaj, Alborz province in Iran. The aircraft was the last civil Boeing 707 in operation. Aircraft The aircraft involved was a Boeing 707-3J9C, c/n 21128, registration EP-CPP. The aircraft was owned by the Islamic Republic of Iran Air Force and had been leased to Saha Airlines. The aircraft was 42 years old at the time. The aircraft had first flown on 19 November 1976, and was delivered that month to the Imperial Iranian Air Force as 5–8312. It had been transferred to Saha Airlines on 27 February 2000, and was re-registered EP-SHK. It was substantially damaged by an uncontained engine failure on 3 August 2009, whilst on a flight from Ahvaz International Airport to Mehrabad International Airport, Tehran. An emergency landing was made at Ahvaz; the aircraft was subsequently repaired. It was returned to the IRIAF in December 2015 and returned to Saha Airlines in May 201 ...

Swept Wing
A swept wing is a wing angled either backward or occasionally forward from its root rather than perpendicular to the fuselage. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity o ...

Pratt & Whitney JT4A
The Pratt & Whitney J75 (civilian designation: JT4A) is an axial-flow turbojet engine first flown in 1955. A two-spool design in the 17,000 lbf (76 kN) thrust class, the J75 was essentially the bigger brother of the Pratt & Whitney J57 (JT3C). It was known in civilian service as the JT4A, and in a variety of stationary roles as the FT4. Design and development In military use, the J75 was used on the Convair F-106 Delta Dart, Lockheed U-2, and Republic F-105 Thunderchief. It was also utilized in the prototype and experimental Avro Canada CF-105 Arrow, Lockheed A-12, Martin P6M-2 SeaMaster, North American YF-107, and Vought XF8U-3 Crusader III. Before the arrival of the Pratt & Whitney JT3D turbofan engine, the JT4A was used to power certain Boeing 707 and Douglas DC-8 models, bringing improved field performance in the medium-range Boeing 707-220 and Douglas DC-8-20, and intercontinental range in the Boeing 707-320 and the Douglas DC-8-30. By late 1959, P&W ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney JT3C
The Pratt & Whitney J57 (company designation: JT3C) is an axial-flow compressor, axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s. The J57 (first run January 1950) was the first 10,000 pound-force, lbf (45 kN) thrust class engine in the United States. It is a two spool engine. The J57/JT3C was developed into the Pratt & Whitney J52, J52 turbojet, the Pratt & Whitney J75, J75/JT4A turbojet, the Pratt & Whitney JT3D, JT3D/TF33 turbofan, and the Pratt & Whitney XT57, XT57 turboprop (of which only one was built). The J57 and JT3C saw extensive use on fighter jets, jetliners, and bombers for many decades. Design and development The J57 was a development of the Pratt & Whitney XT45 (PT4) turboprop engine that was originally intended for the Boeing B-52 Stratofortress, Boeing XB-52. As the B-52 power requirements grew, the design evolved into a turbojet, the JT3. Pratt & Whitney designed the J57 to have a relatively high overall pressure ratio to help ...

Transatlantic Flight
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloon (aircraft), balloons and other aircraft. Early aircraft engines had neither the reliability nor the power to lift the required fuel to make a transatlantic flight. There were difficulties navigating over the featureless expanse of water for thousands of miles, and the weather, especially in the North Atlantic Ocean, North Atlantic, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commerce, commercial, military, diplomacy, diplomatic, and other purposes. History The idea of transatlantic flight came about with the advent of the hot air balloon. The balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough l ...

Transcontinental Flight
A transcontinental flight is a non-stop passenger flight from one side of a continent to the other. The term usually refers to flights across the United States, between the East and West Coasts. History The first transcontinental multi-stop flight across the United States was made in 1911 by Calbraith Perry Rodgers in an attempt to win the Hearst prize offered by publisher William Randolph Hearst. Hearst offered a $US50,000 prize to the first aviator to fly coast to coast, in either direction, in less than 30 days from start to finish. Previous attempts by James J. Ward and Henry Atwood had been unsuccessful. Rodgers persuaded J. Ogden Armour, of Armour and Company, to sponsor the flight, and in return he named the plane after Armour's grape soft drink "Vin Fiz". Rodgers left from Sheepshead Bay, New York, on September 17, 1911, at 4:30 pm, carrying the first transcontinental mail pouch. He crossed the Rocky Mountains on November 5, 1911, and landed at Tournament Par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domestic Flight
A domestic flight is a form of commercial flight within civil aviation where the departure and the arrival take place in the same country. Airports serving domestic flights only are known as domestic airports. Domestic flights are generally cheaper and shorter than most international flights. Some international flights may be cheaper than domestic ones due to the short distance between the pair of cities in different countries, and also because domestic flights might, in smaller countries, mainly be used by high paying business travellers, while leisure travellers use road or rail domestically. As far as security checks is concerned, the security check only verifies the traveler's identity. Domestic flights are the only sector of aviation not exhibiting a global long term growth trend due to many smaller countries increasingly replacing short domestic routes with high speed rail; that said, most of the busiest air routes in the world are domestic flights. Some smaller cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airline
An airline is a company that provides civil aviation, air transport services for traveling passengers or freight (cargo). Airlines use aircraft to supply these services and may form partnerships or Airline alliance, alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an Air operator's certificate, air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or Air charter, charter operators. The List of airlines by foundation date, first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Russian Aeroflot (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to 1980s and b ...

Jet Age
The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines and the social and cultural changes fostered by commercial jet travel. Jet airliners were able to fly higher, faster, and farther than older Reciprocating engine, pistonpowered propliners, making transcontinental and intercontinental travel considerably faster and easier. Aircraft leaving North America and crossing the Atlantic Ocean (and later, the Pacific Ocean) could now fly to their destinations non-stop, making much of the world accessible within a single day's travel for the first time. Large jetliners could carry more passengers than piston-powered airliners, which caused air fares to decline and opened international travel to a broader range of socioeconomic groups. In addition to pure jet engines, turbine-driven propeller engines delivered a smoother ride and better fuel efficiency. One exception to jet-powered domination by large airliners was the cont ...
