Boeing 707

The Boeing 707 is a mid-sized, long-range, narrow-body, four-engine jet airliner built by Boeing Commercial Airplanes from 1958 to 1979. Its name is commonly pronounced as "seven oh seven". Versions of the aircraft have a capacity from 140 to 219 passengers and a range of 2,500-5,750 nautical miles (4,630-10,649 kilometers).
Developed as Boeing's first jet airliner, the 707 is a swept-wing design with podded engines. Although it was not the first jetliner in service, the 707 was the first to be commercially successful. Dominating passenger air transport in the 1960s and remaining common through the 1970s, the 707 is generally credited with ushering in the Jet Age. It established Boeing as one of the largest manufacturers of passenger aircraft, and led to the later series of airliners with "7x7" designations. The later 720, 727, 737, and 757 share elements of the 707's fuselage design.
The 707 was developed from the Boeing 367-80, a prototype jet first flown in 1954. A larger fuselage cross-section and other modifications resulted in the initial-production 707-120, powered by Pratt & Whitney JT3C turbojet engines, which first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958. Later derivatives included the shortened long-range 707-138 and the stretched 707-320, both of which entered service in 1959. A smaller short-range variant, the 720, was introduced in 1960. The 707-420, a version of the stretched 707 with Rolls-Royce Conway turbofans, debuted in 1960, while Pratt & Whitney JT3D turbofans debuted on the 707-120B and 707-320B models in 1961 and 1962, respectively.
The 707 has been used on domestic, transcontinental, and transatlantic flights, and for cargo and military applications. A convertible passenger-freighter model, the 707-320C, entered service in 1963, and passenger 707s have been modified to freighter configurations. Military derivatives include the E-3 Sentry airborne reconnaissance aircraft and the C-137 Stratoliner VIP transports. Boeing produced and delivered 1,011 airliners including the smaller 720 series; over 800 military versions were also produced. Ten Boeing 707s were in commercial service in July 2013.

Boeing 717

The Boeing 717 is a twin-engine, single-aisle jet airliner, developed for the 100-seat market. The airliner was designed and originally marketed by McDonnell-Douglas as the MD-95, a derivative of the DC-9 family. Capable of seating up to 134 passengers, the 717 has a design range of 2,060 nautical miles (3,815 kilometers). It is powered by two Rolls-Royce BR715 turbofan engines mounted at the rear of the fuselage.
The first order was placed in October 1995 by ValuJet Airlines (later AirTran Airways); McDonnell Douglas and Boeing merged in 1997 prior to production. The airliner entered service in 1999 as the Boeing 717. Production ceased in May 2006 after 156 were built. There were 154 Boeing 717 aircraft in service as of July 2016.

Boeing 720

The Boeing 720 is a four-engine narrow-body short- to medium-range passenger jet airliner. Developed by Boeing in the late 1950s from the Boeing 707, the 720 has a shorter fuselage and less range. The 720 first flew in November 1959 and the model entered service with launch customer United Airlines in July 1960.
Two primary versions of the aircraft were built. The original 720 with Pratt & Whitney JT3C turbojet engines entered service in 1960, while the improved 720B with Pratt & Whitney JT3D turbofans entered service in 1961. Some 720s were later converted to 720B specification.
Although only 154 were built, the Boeing 720 and 720B were profitable due to the low research and development costs of their being slightly modified versions of the 707-120. They were later replaced by the Boeing 727. Some 720s are on display at the Utah Aviation Museum.

Boeing 727

The Boeing 727 is a midsized, narrow-body three-engined jet aircraft built by Boeing Commercial Airplanes from the early 1960s to 1984. It can carry 149 to 189 passengers and later models can fly up to 2,700 nautical miles (5,000 kilometers) nonstop. Intended for short and medium-length flights, the 727 can use relatively short runways at smaller airports. It has three Pratt & Whitney JT8D engines below the T-tail, one on each side of the rear fuselage with a center engine that connects through an S-duct to an inlet at the base of the fin. The 727 is Boeing's only trijet aircraft.
The 727 followed the 707, a quad-jet airliner, with which it shares its upper fuselage cross-section and cockpit design. The 727-100 first flew in February 1963 and entered service with Eastern Air Lines in February 1964; the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that December. The 727 became a mainstay of airlines' domestic route networks and was also used on short- and medium-range international routes. Passenger, freighter, and convertible versions of the 727 were built.
The 727 was heavily produced into the 1970s; the last 727 was completed in 1984. As of July 2016, a total of 64 Boeing 727s (4× 727-100s and 60× -200s) were in commercial service with 26 airlines, plus a few more in government and private use. Airport noise regulations have led to 727s being equipped with hush kits. Since 1964 there have been 118 fatal incidents involving the Boeing 727. Successor models include variants of the 737 and the 757-200.

Boeing 737

The Boeing 737 is an American short- to medium-range twinjet narrow-body airliner. Originally developed as a shorter, lower-cost twin-engine airliner derived from Boeing's 707 and 727, the 737 has developed into a family of ten passenger models with capacities from 85 to 215 passengers. The 737 is Boeing's only narrow-body airliner in production, with the 737 Next Generation (-700, -800, and -900ER) variants currently being built. Production has also begun on the re-engined and redesigned 737 MAX, which is set to enter service in 2017.
Originally envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered airline service in February 1968 at Lufthansa. Next, the lengthened 737-200 entered service in April 1968. In the 1980s Boeing launched the -300, -400, and -500 models, subsequently referred to as the Boeing 737 Classic series. The 737 Classics added capacity and incorporated CFM56 turbofan engines along with wing improvements.
In the 1990s, Boeing introduced the 737 Next Generation, with multiple changes including a redesigned, increased span laminar flow wing, upgraded "glass" cockpit, and new interior. The 737 Next Generation comprises the four -600, -700, -800, and -900 models, ranging from 102-138 feet (31.09-42.06 meters) in length. Boeing Business Jet versions of the 737 Next Generation are also produced.
The 737 series is the best-selling jet commercial airliner in history. The 737 has been continuously manufactured by Boeing since 1967 with 9,486 aircraft delivered and 4,478 orders yet to be fulfilled as of April 2017. Assembly of the 737 is performed at the Boeing Renton Factory in Renton, Washington. Many 737s serve markets previously filled by 707, 727, 757, DC-9, and MD-80/MD-90 airliners, and the aircraft currently competes primarily with the Airbus A320 family. As of 2006, there were an average of 1,250 Boeing 737s airborne at any given time, with two departing or landing somewhere every five seconds.

Boeing 737 Classic

The Boeing 737 Classic refers to the -300/-400/-500 series of the Boeing 737. It is the second generation derivative of the 737, following the original -100/-200 models that began production in 1966. They are short- to medium-range, narrow-body jet airliners. Produced by Boeing Commercial Airplanes from 1984 to 2000, the 737 Classic includes three variants and can seat between 145 and 188 passengers. Improvements over the previous generation of 737 aircraft included CFM International CFM56 high bypass ratio turbofan engines, upgraded avionics, and increased passenger capacity (in the -300/-400 models).
The first model of the Classic series, the 737–300, entered service in 1984. It was followed by a stretched model, the 737-400, which entered service in 1988, followed by shortened 737-500, the smallest variant in the classic series, in 1990. In total, 1,988 aircraft were delivered. The Classic series was introduced as the 'new generation' of the 737, but following the introduction of the 737 Next Generation in the mid-1990s, was officially designated as the 737 Classic series.

Boeing 737 MAX

The Boeing 737 MAX is an American narrow-body aircraft series being developed by Boeing Commercial Airplanes as the fourth generation of the Boeing 737, succeeding the Boeing 737 Next Generation. The program was launched on August 30th, 2011. The first flight was on January 29th, 2016. It gained FAA certification on March 9th, 2017. The first delivery was a MAX 8 on May 16th, 2017 to Malindo Air, which debuted it on May 22nd, 2017.
The 737 MAX is based on earlier 737 designs but re-engined with more efficient CFM International LEAP-1B along with aerodynamic improvements, most notably split-tip winglets, and airframe modifications. It is offered in four lengths, the 737 MAX 7, MAX 8 and MAX 9 replacing the 737-700, -800 and -900, and a further stretched MAX 10, typically offering 138 to 230 seats and a 3,215-3,825 nautical mile (5,954-7,084 km) range. Through July 2017, it received 3,816 firm orders.

Boeing 737 Next Generation

The Boeing 737 Next Generation, commonly abbreviated as 737NG, is the name given to the −600/-700/-800/-900 series of the Boeing 737 airliner. It is the third generation derivative of the 737, and follows the 737 Classic (−300/-400/-500) series, which began production in the 1980s. They are short- to medium-range, narrow-body jet airliners. Produced since 1996 by Boeing Commercial Airplanes, the 737NG series includes four variants and can seat between 110 and 210 passengers.
As of July 2017, a total of 7,114 737NG aircraft have been ordered, of which 6,466 have been delivered. The remaining orders are in the -700, -700 BBJ, -800, -800 BBJ and -900ER variants. The 737NG's primary competition is with the Airbus A320 family. Upgraded and re-engined models in development as the 737 MAX series are to eventually supplant the 737NG, with the first 737 MAX delivered in 2017.

Boeing 747-400

The Boeing 747-400 is a major development and the best-selling model of the Boeing 747 family of jet airliners. While retaining the four-engine wide-body layout of its predecessors, the 747-400 embodies numerous technological and structural changes to produce a more efficient airframe. Its most distinguishing features versus preceding 747 models are 6-foot (1.83 meter) winglets mounted on 6-foot (1.83 meter) wing tip extensions, which are found on all 747-400s except for Japanese domestic market versions.
The 747-400 is equipped with a two-crew glass cockpit, which dispenses with the need for a flight engineer, along with more fuel-efficient engines, an optional fuel tank in the horizontal stabilizer, and revised fuselage/wing fairings. The aircraft also features an all-new interior with upgraded in-flight entertainment architecture. As on the 747-300, passenger variants include a stretched upper deck as standard. The model has a maximum capacity of 660 passengers with the 747-400D variant, and can fly non-stop for up to 7,670 nautical miles (14,205 kilometers) with maximum payload, depending on model.
Northwest Airlines first placed the 747-400 in commercial service in February 9, 1989. The 747-400 was produced in passenger (−400), freighter (−400F), combi (−400M), domestic (−400D), extended range passenger (−400ER) and extended range freighter (−400ERF) versions. The last 747−400, a -400ERF, was delivered in 2009. The 747-400 is the second-most recent version of the Boeing 747 family, having been superseded by the improved Boeing 747-8.

Boeing 747-8

The Boeing 747-8 is a wide-body jet airliner developed by Boeing Commercial Airplanes. Officially announced in 2005, the 747-8 is the third generation of the 747, with a lengthened fuselage, redesigned wings, and improved efficiency. The 747-8 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest passenger aircraft in the world.
The 747-8 is offered in two main variants: the 747-8 Intercontinental (747-8I) for passengers and the 747-8 Freighter (747-8F) for cargo. The first 747-8F performed the model's maiden flight on February 8th, 2010, with the 747-8I following on March 20th, 2011. Delivery of the first freighter aircraft occurred in October 2011 and the passenger model began deliveries in 2012. As of January 2017, confirmed orders for the 747-8 total 150: 88 of the freighter version, and 62 of the passenger version.

Boeing 747SP

The Boeing 747SP is a modified version of the Boeing 747 jet airliner which was designed for ultra-long-range flights. The SP stands for "Special Performance". The 747SP is similar to the 747-100 except for the shortened fuselage, larger tailplane, and simplified trailing edge flaps. The weight saved by the shorter fuselage permits longer range and increased speed relative to other 747 configurations.
Known during development as the short-body 747SB, the 747SP was designed to meet a 1973 joint request from Pan American World Airways and Iran Air, who were looking for a high-capacity airliner with sufficient range to cover Pan Am's New York–Middle Eastern routes and Iran Air's planned Tehran–New York route. The aircraft also was intended to provide Boeing with a mid-size wide-body airliner to compete with existing trijet airliners.
The 747SP first entered service with Pan Am in 1976. The aircraft was later acquired by VIP and government customers. While in service, the 747SP set several aeronautical performance records, but sales did not meet the expected 200 units, and production ultimately totaled 47 aircraft.

Boeing 757

The Boeing 757 is a mid-size, narrow-body twin-engine jet airliner that was designed and built by Boeing Commercial Airplanes. It is the manufacturer's largest single-aisle passenger aircraft and was produced from 1981 to 2004. The twinjet has a two-crew member glass cockpit, turbofan engines of sufficient power to allow takeoffs from relatively short runways and higher altitudes, a conventional tail and, for reduced aerodynamic drag, a supercritical wing design. Intended to replace the smaller three-engine 727 on short and medium routes, the 757 can carry 200 to 295 passengers for a maximum of 3,150 to 4,100 nautical miles (5,830 to 7,590 km), depending on variant. The 757 was designed concurrently with a wide-body twinjet, the 767, and owing to shared features pilots can obtain a common type rating that allows them to operate both aircraft.
The 757 was produced in two fuselage lengths. The original 757-200 entered service in 1983; the 757-200PF, a package freighter (PF) variant, and the 757-200M, a passenger-freighter combi model, debuted in the late 1980s. The stretched 757-300, the longest narrow-body twinjet ever produced, began service in 1999. Passenger 757-200s have been modified to special freighter (SF) specification for cargo use, while military derivatives include the C-32 transport, VIP carriers, and other multi-purpose aircraft. Private and government operators have also customized the 757 for research and transport roles. All 757s are powered by Rolls-Royce RB211 or Pratt & Whitney PW2000 series turbofans.
Eastern Air Lines and British Airways placed the 757 in commercial service in 1983. The narrow-body twinjet succeeded earlier single-aisle airliners, and became commonly used for short and mid-range domestic routes, shuttle services, and transcontinental U.S. flights. After regulators granted approval for extended flights over water (ETOPS) in 1986, airlines also began using the aircraft for intercontinental routes. Major customers for the 757 included U.S. mainline carriers, European charter airlines, and cargo companies. The airliner has recorded eight hull-loss accidents, including seven fatal crashes, as of September 2015.
Production of the 757 ended in October 2004, after 1,050 had been built for 54 customers. The 757-200 was by far the most popular model, with 913 built. Diminished sales amid an airline industry trend toward smaller jetliners led Boeing to end production without a direct replacement, in favor of the 737 family. The last 757 was delivered to Shanghai Airlines in November 2005. In July 2015, 738 of the narrow-body twinjets were in airline service; Delta Air Lines is the largest operator with 138 aircraft.
