The Boeing 747, commonly nicknamed the "Jumbo Jet", is a long-haul, widebody commercial airliner manufactured by Boeing. Known for its impressive size, it is among the world's most recognizable aircraft. First flown commercially in 1970, it has held the passenger capacity record for 37 years and was the first commercial wide-body aircraft.
The four-engine 747, produced by Boeing's Commercial Airplane unit, uses a double decker configuration for part of its length. The hump created by the upper deck has made the 747 a highly recognizable icon of air travel. A typical three-class layout accommodates 416 passengers, while a two-class layout accommodates a maximum of 524 passengers. The 747-400, the latest version in service, flies at high-subsonic speeds of Mach 0.85 (567 mph or 913 km/h), and features an intercontinental range of 7,260 nautical miles (8,350 mi, 13,450 km).[4]
The 747 was expected to become obsolete after sales of 400 units, but it has outlived many of its critics' expectations and production passed the 1,000 mark in 1993. As of June 2007 1387 planes had been built, with 120 more in various configurations on order. The latest development of the aircraft, the 747-8, is planned to enter service in 2009.[5]

[edit] Development
[edit] Background
The 747 was born from the increase in air travel in the 1960s. The era of commercial jet transportation, led by the enormous popularity of the Boeing 707 and Douglas DC-8, had revolutionized long distance travel. Boeing had already developed a study for a very large fixed-wing aircraft while bidding on a US military contract for a huge cargo plane.[6] Even before it lost the contract to Lockheed's C-5 Galaxy in September 1965 Boeing came under pressure from Juan Trippe, president of its most loyal airline customer Pan Am, to build a large passenger plane that would be over twice the size of the 707.
In 1965 Joe Sutter was transferred from Boeing's 737 development team to manage the studies for a new airliner, already assigned its model number 747. The original design was a full-length double-decker fuselage seating eight across (3–2–3) on the lower deck and seven across (2–3–2) on the upper deck.[7] However, concern over evacuation routes and limited cargo carrying capability caused this idea to be scrapped in early 1966 in favor of wider single deck, becoming the first wide-body airliner.[8]
One of the principal technologies that enabled an airplane as large as the 747 to be conceived was the high-bypass turbofan engine. This promised to deliver double the power of the earlier turbojets while consuming a third less fuel. General Electric had pioneered the concept but were fully committed to developing the engine for the C-5 Galaxy. Pratt & Whitney was also working on the same principle, and by late 1966 Boeing, Pan-Am and Pratt & Whitney agreed that Pratt would develop a new engine, designated JT9D, to power the 747. Four of these engines were to be mounted in pods below the 747's wings.

At the time, it was widely thought that the 747 would eventually be superseded by supersonic transport (SST) aircraft, so Boeing designed it such that it could easily be adapted to carry freight, so that it could remain in production if and when sales of the passenger version dried up. The cockpit was therefore placed on a shortened upper deck so that a nose cone loading door could be included, thus creating the 747's distinctive "bulge". However, supersonic transports, including the Concorde and Boeing's never-produced 2707, were not widely adopted. SSTs were less fuel-efficient at a time when fuel prices were soaring, very noisy during takeoff and landing, and their ability to operate at supersonic speeds over land was limited by regulations concerning their sonic booms.[9]
To appease concerns about the safety and flyability of such a large passenger aircraft, the 747 was designed with multiple structural redundancy, four redundant hydraulic systems, and quadruple main landing gear with 16 wheels which provided a good spread of support on the ground and safety in the event of tire blow-outs. In addition, the 747 had split control surfaces and sophisticated triple-slotted flaps that minimised landing speeds allowing it to use standard-length runways. The wing was swept back at an unusually large angle of 37.5 degrees which was chosen in order to minimize the wing span, thus allowing the 747 to use existing hangars.[8][10]
In April 1966, Pan Am ordered 25 of the initial 100 series for US$525 million. During the ceremonial 747 contract signing banquet in Seattle, concurrent to Boeing's 50th Anniversary, Juan Trippe predicted the 747 as "...a great Weapon for peace, competing with intercontinental missiles for mankind's destiny.", according to an interview with Malcolm T. Stamper.[11] As launch customer,[1][12] and because of its early involvement before placing a formal order, Pan Am was able to influence the design and development of the 747 to an extent not seen by a single airline before or since.[13]

[edit] Production
Boeing did not have a facility large enough to assemble the giant aircraft, so it had to build a new one. The company looked at a number of locations including Walnut Creek, California and Tacoma, Washington. In the end, it decided to build the new plant some 30 miles north of Seattle on a site adjoining a military base at Paine Field near Everett, Washington,[14] which had a 9,500 foot runway. In June 1966, Boeing bought the 780 acre site.[1]
While developing the 747 had been a major challenge, constructing the plant in which to build it was also a huge undertaking. Boeing president William M. Allen asked Malcolm T. Stamper, then head of the company's turbine division, to lead construction of the Everett factory and start up production of the 747.
To level the site, over four million cubic yards of earth had to be moved.[15] Such was the shortage of time that the 747's full-scale mock-up had to be built even before the factory roof had been constructed above it.[16] The plant is the largest building by volume ever built.[6]
Boeing had promised to deliver the 747 to Pan Am by 1970, which gave it less than four years to develop, build and test the aircraft. Work progressed at such a breakneck pace that all those who worked on the development of the 747 were given the nickname "The Incredibles".[6]
[edit] Testing
Before the first 747 was even fully assembled, testing began on numerous components and systems. One of the most anxiously awaited tests was the emergency evacuation, to see how long it took for 560 volunteers to exit from a cabin mock-up using the plane's emergency chutes. The first full-scale test took two and a half minutes instead of the maximum 90 seconds mandated by the Federal Aviation Administration, and resulted in several injuries to the volunteers. Subsequent tests achieved the 90-second limit, albeit at the cost of more injuries. Most problematic was evacuation from the airplane's upper deck: instead of a slide there was an escape harness attached to a reel.[17]
Before the 747's first flight Boeing built an unusual training device known as "Waddell's Wagon" (named after the 747 test pilot, Jack Waddell), which consisted of a mock-up cockpit mounted on the roof of a truck, for training pilots how to taxi the plane from the high upper deck position.[6]

On September 30, 1968 the first 747, N7470, was rolled out of the assembly building in front of the world's press and representatives of the 26 airlines that had ordered the plane.[18] Over the following months preparations were made for the first flight, which took place successfully on February 9, 1969, with test pilots Jack Waddell and Brien Wygle at the controls,[19][20] and Jess Wallick at the flight engineer's station. In spite of a minor problem with one of the flaps, the flight confirmed that the 747 handled extremely well; the plane was found to be largely immune to "dutch roll", a phenomenon that had been a major hazard to the early swept-wing jets.[21]
Later stages of the flight test program revealed some problems: flutter testing showed that the wings suffered oscillation in certain conditions. These difficulties were partly solved by reducing the stiffness of some wing components. However, a particularly severe high-speed flutter problem was only solved by inserting depleted uranium counterweights as ballast in the outboard engine nacelles of the early 747s.[22] This measure caused some anxiety when several of these aircraft were lost, such as the 1991 crash of China Airlines Flight 358 in Wanli and 1992 crash of El Al Flight 1862 at Amsterdam.[23][24]
The flight test program was considerably hampered by problems with the plane's JT9D engines: these included engine stalls caused by rapid movements of the throttles and distortion of the turbine casings after a short period of service.[25] The problems caused 747 deliveries to be delayed several months, resulting in up to 20 planes at one time being stranded at the Everett plant awaiting engines.[26] The program was further set back when the third of five test aircraft suffered serious damage while attempting to land at Boeing's Renton plant where it was being taken to have its test equipment removed and a cabin installed; pilot Ralph C. Cokely undershot the short runway and sheared off the aircraft's landing gear.[27] However, these difficulties did not prevent Boeing taking one of the test aircraft to the 28th Paris Air Show in the summer of 1969 where it was displayed to the general public for the first time.
The 747 finally achieved its FAA airworthiness certificate in December 1969, paving the way for its introduction into service.
The huge cost of developing the 747 and building the Everett factory meant that Boeing had to borrow heavily from a banking syndicate to fund the project. During the final months before delivery of the first plane the Company had to repeatedly request additional funding from the syndicate to enable it to complete the project; had this been refused the survival of the Company itself would have been threatened.[28][12] However, the gamble paid off and Boeing enjoyed a monopoly in the very large passenger aircraft segment for over 35 years until the arrival of the Airbus A380.[29]

On January 15, 1970, American First Lady Pat Nixon officially christened a Pan Am Boeing 747 at Washington Dulles International Airport in the presence of Pan Am chairman Najeeb Halaby. Instead of a bottle of champagne, red, white and blue water was sprayed on the plane. The first commercial flight of a Boeing 747 took place on January 22, 1970 and was operated by Pan Am between New York's John F. Kennedy International Airport and London Heathrow Airport. Pan Am added 747 services to London from Boston, Washington and other cities during the spring and summer of 1970. Overnight, a new standard of air travel had been created and other airlines rushed to bring their own 747s into service. Trans World Airlines, Japan Airlines, Lufthansa, BOAC and Northwest Orient were among the first carriers to use 747s on long-haul flights. American Airlines started a 747 service between New York and Los Angeles by the summer of 1970, and in September 1970 added nonstop 747 flights between Washington and Los Angeles. Soon afterward American Airlines added a 747 service from Boston to Chicago and on to Los Angeles. In addition to its foreign destinations, TWA offered 747 flights between San Francisco and New York by early 1971.
Initially, many airlines regarded the 747 with skepticism. McDonnell Douglas and Lockheed were working on wide-body three engine "tri-jets", which were smaller than the 747. Many airlines believed the 747 would prove too large for an average long distance flight, investing instead in tri-jets. There were also concerns that the 747 would not be compatible with existing airport infrastructure—an issue which has resurfaced with the Airbus A380, due to its double-deck feature.[30]
Fuel efficiency was another concern, and this became more critical after the Arab oil crisis, which led to economic stagnation in the United States. This lowered the number of airline passengers and made it difficult for airlines to fill their new 747s, so American Airlines replaced coach seats on its 747s with piano bars in an attempt to attract more customers. Eventually, it relegated its 747s to cargo service and then sold them. Continental Airlines also removed its 747s from service after several years. The advent of smaller, more efficient wide bodies, starting with the trijet DC-10 and L-1011, and followed by the twinjet 767 and A300, took away much of the 747's original market, especially as airline deregulation made point-to-point international service more common. Other airlines that have removed 747s from their fleet include Delta, Air Canada, Eastern, Aer Lingus, Avianca, SAS, TAP, America West and Olympic Airways.
However, many international carriers continued to use the 747 on their busiest routes. The type remained popular among Asian airlines for short and medium-range flights between major cities: in Japan, domestic airlines continue to pack 747s to their maximum passenger capacity. Elsewhere, 747s remain popular on long-range trunk routes, such as transoceanic flights and the Kangaroo routes between Europe and Australia. The largest fleet of 747s today belongs to Japan Airlines, at approximately 78 (series -200s, -300s and 44 -400s). British Airways has the next largest fleet of 747s, comprising 57 747-400s.

The 747 remained the largest passenger airliner until the maiden flight of the Airbus A380. The 747 was the heaviest airliner in regular service until the use of the Antonov An-124 Ruslan in 1982, the 747-400ER model regaining the title in 2000. The Antonov An-225 cargo transport remains the world's largest aircraft by a number of measures (including the most accepted measure of [31] maximum gross takeoff weight and length) and is in service, while the Hughes H-4 Hercules is the largest by only wingspan length, but never flew more than once a few feet off the ground[32] Only 2 An-225 aircraft have been produced with only one still flying, while the 747 and A380 are made for serial mass production.
[edit] Future of the 747
Since the arrival of the 747-400 in 1989, several stretching schemes for the 747 have been proposed, but the only design to be adopted is 2005's 747-8. The 747-X program was launched in 1996 as Boeing's response to the Airbus A3XX proposal. The 747-X would have consisted of the 747-500X and 747-600X, seating up to 800 passengers and powered by the Engine Alliance GP7200 turbofan developed for the Airbus A380. However, the airlines preferred Boeing to develop an all-new design instead of an updated 747, and the plan was dropped after a few months.
After development of the Airbus A380 formally began in 2000, Boeing reexamined its 747-X studies but instead focused on the Sonic Cruiser,[33] and then on the 787 after the Sonic Cruiser program was put on hold indefinitely.[34] Some of the ideas developed for the 747-X were, however, used on the 747-400ER.
In early 2004, Boeing rolled out tentative plans the 747 Advanced. Similar in nature to the 747-X plans, the stretched 747 Advanced uses advanced technology from the 787 to modernize the design and its systems. On November 14, 2005, Boeing announced it was launching the 747 Advanced as the 747-8.[35] Due to long delays in production of the Airbus A380, two customers signed additional orders,[36][37] two customers cancelled their orders and several launch customers deferred delivery, or considered switching their order to the 747-8 and 777F aircraft.[38][39]
Eventually, the 747 (in all forms) may be replaced by a clean-sheet aircraft dubbed "Y3".
[edit] Variants
There are five major variants of the 747. The 747-100 was the original and launched in 1966. The 747-200 followed soon after with an order in 1968. The 747-300 was launched in 1980, and was followed in 1985 by the 747-400. Lastly, the 747-8 was launched in 2005. Several versions of each variant have been produced, and many of the early variants were in production at the same time, especially in the 1980s.
[edit] 747-100
The first model of the jet, the 747-100, rolled out of the new Everett facility on September 30, 1968. The prototype, named City of Everett, first flew on February 9, 1969,[40] and on January 22, 1970 the 747-100 entered service with launch customer Pan American World Airways on the New York-London route.[41] The flight was supposed to occur on January 21, but engine overheating made the original plane unusable and it had to be substituted, creating a more than 6-hour delay to the next day.[41] The basic -100 has a range of about 4,500 miles (7,242 km) with full load.[42]
The very first 747-100s off the line were built with six (three per side) upper-deck windows to accommodate upstairs lounge areas. A little later, as airlines began to use the upper-deck for premium passenger seating instead of lounge space, Boeing offered a ten window upper deck as an option, and it quickly became the standard. Some -100s were even retrofitted with the new configuration.

With a MTOW of 735,000 lb compared to the 833,000 lb of the 747-200, no freighter model of this aircraft was offered directly by Boeing. However, upon airline retirement, many 747-100s have been converted to freighters over the years. Their cheap acquisition costs more than compensate for lack of carrying capacity. They are also ideal for parcels since volume is paramount to weight. A 747-100 is owned by General Electric and used as a testbed for their engines such as General Electric GEnx.
[edit] 747-100B
The 747-100 was later superseded by the 747-100B, which has a stronger airframe and undercarriage design.[42] This increased maximum take-off weight to 750,000 pounds (340,000 kg). Optional engine models were offered by Rolls-Royce (RB211) and GE (CF6), but only the Rolls-Royce option was taken up by Saudia. The remaining customers opted for the standard Pratt & Whitney JT9D of the -100. The 747-100B was only delivered to Iran Air and Saudia (now Saudi Arabian Airlines).[43]
[edit] 747-100SR
With requests from Japanese airlines, Boeing developed the 747SR as a 'Short Range' variant of the 747-100. The SR has a lower fuel capacity, but can carry more passengers – up to 498 passengers in early versions and more than 550 passengers in later models. The 747SR has a modified body structure to accommodate the added stress accumulated from a greater number of take-offs and landings. Later on, short range versions were developed also of the -100B and the -300. The SR aircraft are primarily used on domestic flights in Japan.[44]
Two 747-100B/SRs were delivered to Japan Airlines (JAL) with a stretched upper deck to accommodate more passengers. This is known as the "SUD" (stretched upper deck) modification.
All Nippon Airways (ANA) operated 747SR on domestic Japanese routes with 455-456 seats but retired the aircraft on 10 March 2006. JAL operated the 747-100B/SR/SUD aircraft with 563 seats on domestic routes which retired in the third quarter of 2006. JAL and JALways have also been operating the -300SRs on domestic leisure routes and to other parts of Asia. With the arrival of the much more economical Boeing 777-300, the SRs are now being replaced, with just a very few still in operation.

Total production of -100 versions were 250 aircraft. Of these, 167 were 747-100, 45 were SP, 29 were SR, and 9 were 100B. In August 2006, a total of 38 Boeing 747-100 aircraft (all versions) were in airline service with Iran Air (1), Japan Airlines (1), Orient Thai Airlines (2), Saudi Arabian Airlines (7), Evergreen International Airlines (6), Kalitta Air (6), Polar Air Cargo (1) and United Parcel Service (7).[45]
[edit] 747SP
Main article: Boeing 747SP
The 747SP was a shortened version of the 747-100. It entered service in 1976, with Pan Am. Apart from the upcoming 747-8 the SP is the only 747 with a modified length fuselage. It was designed to fly higher, faster and longer than the 747-100. Boeing hoped that SP would take orders from the Douglas DC-10 and create a niche market, but in the end only 45 were built.
As of August 2007, 17 Boeing 747SP aircraft were in service with: Iran Air (3), Saudi Arabian Airlines (1), and Syrian Arab Airlines (2). Additionally, executive versions are in service with Qatar Government (1), Bahrain Government (2), Saudi Arabian Government (2), Oman Government (1), Yemen Government (1) and Las Vegas Sands Group (1). Also, Pratt and Whitney Flight Test (1), and Ernest Angley Ministries (1). Finally, NASA's Dryden Flight Research Center has one (1) for the SOFIA experiment. [46]

Entering service in 1971, and further improved over successive years, the 747-200 had more powerful engines and higher takeoff weights than the -100, allowing it to fly farther. Optional engine models by GE (CF6) and Rolls-Royce (RB211) were offered for the first time. A few early build -200s retained the three window configuration of the -100 on the upper deck, but most were built with a ten window per side configuration. As on the -100, a stretched upper deck (SUD) modification was offered much later.
KLM remains the only airline to perform the retrofit their -200s with the SUD option themselves. A total of 10 conversion were operated by KLM, some performed in-house and some converted by Boeing. The French airline, UTA, and Japan Air Lines also had two aircraft converted each. From a distance, the 747-200 SUD looks very similar to the 747-300 with both having a stretched upper deck and absence of winglets as in found in the 747-400.
Today, many -200s are still in passenger operation, though in recent years retirement and conversion to freighters has accelerated.
[edit] 747-200B
The 747-200B is an improved version of the 747-200, with increased fuel capacity and more powerful engines. Qantas took delivery of these from 1971. It comes in a combi version as well. The -200B aircraft have a full load range of about 6,700 miles (10,700 km).
[edit] 747-200C
The 747-200C Convertible is essentially a passenger aircraft that can be converted to a freighter and back when needed. The seats are removable and the fuselage has a much bigger door on the maindeck for cargo entry. The -200C could be fitted with a nose door.
[edit] 747-200M
This type can carry both freight and passengers but, unlike the 200C, it can do so at the same time. A wall half way through the main deck separates the cargo at the back from the passengers at the front. This type carries cargo throughout the lower deck and on half the main deck, along with roughly 200 passengers. Also known as the 747-200 Combi.
[edit] 747-200F
This is a freighter version of the -200 model. It could be fitted with or without the nose door. It has a 105 ton capacity and a MTOW of up to 833,000 lb. It entered service in 1972 with Lufthansa.
Total production was 393 of -200 models. Of these, 225 were 747-200, 78 were M, 73 were F, 13 were C, and 4 were military. In August 2006 a total of 239 Boeing 747-200 aircraft (all versions) were in airline service. Major operators include: Japan Airlines (13), Nippon Cargo Airlines (10), Air Atlanta Icelandic (15), Air France (9), Atlas Air (16), Kalitta Air (12), Northwest Airlines (28), Cathay Pacific Airways (7) and Southern Air (9). Some 41 other airlines operate smaller numbers of the type.[45]
[edit] 747-300
Following the aborted 747-300 Trijet, Boeing explored increasing the capacity of the 747 by using fuselage plugs either to stretch the entire aircraft to seat around 600 passengers or to stretching the upper deck the entire length of the fuselage. These plans were dropped in favor of a more simple stretch of the upper deck part way along the length of the fuselage.[47] The 747-300 name was revived for this new version, which was introduced in 1980. It was the first 747 model to feature a "stretched upper deck", which was 23 ft 4 inches (7.1 m) longer than earlier variants. The -300 also had a straight staircase for the upper deck instead of a spiral, and this created more room both below and above for more seats. With minor aerodynamic changes, Boeing increased the cruise speed of the -300 to Mach 0.85 from Mach 0.84 on the -100/-200. Also, with improved fuel economy, range improved to 7,700 mi (12,400 km).
Swissair was the launch customer for the 747-300, but the first plane was delivered to French airline UTA on March 1, 1983.[48] Boeing never launched a 747-300F as it had no operating advantage over the 747-200F, no cargo being carried on the upper deck.
Despite the -300's improvements, only 81 aircraft were ordered, 56 for full passenger use, 21 M and 4 SR. One reason for its limited sales was the imminent launch of the much more advanced 747-400 in 1985 (just two years after the -300 entered service) for which most airlines were prepared to wait. Today, most of the -300 versions are still in passenger operation, mainly in south and west Asia.
[edit] 747-300M
The -300M had similar cargo capacity to the -200M, but with the stretched upper deck it could carry more passengers. This proved popular in the fleet of KLM on their Africa routes that had few passengers but considerable air freight.

The Japanese airlines again asked for a high capacity domestic model and Boeing offered the SR. JAL operated such aircraft with over 600 seats on Okinawa-Tokyo route and elsewhere.
Airlines (at August 2006) operating the Boeing 747-300 include JAL/JALways (12), Saudi Arabian Airlines (9), Pakistan International Airlines (PIA) (6), Qantas (6) and Air Atlanta Icelandic (6). Some 16 other airlines operate smaller numbers of the type and a total of 72 Boeing 747-300 aircraft (all versions) were in airline service.[45]

The 747-400 was offered in several versions like previous 747 variants. It added 6 feet (1.8 m) wing tip extensions and 6 feet (1.8 m) winglets, tail fuel tanks, revised engines, an all-new interior, and an all-new glass cockpit which dispensed with the need for a flight engineer.
The passenger version first entered service in February 1989 with Northwest Airlines on the Minneapolis to Phoenix route.[50] The combi version entered service in September 1989 with KLM. In 1989, a Qantas 747-400 flew non-stop from London to Sydney, a distance of 9,720 nmi (11,190 mi, 18,000 km) in 20 hours and 9 minutes, although this was a delivery flight with no passengers or freight aboard.[51] The freighter version entered service in November 1993 with Cargolux.
The extended range freighter (ERF) entered service in October 2002. The next month, the extended range (ER) passenger version entered service with Qantas, the only airline ever to order the passenger version of the 747-400ER. Qantas uses the aircraft on its Melbourne-Los Angeles flights, which are too long to operate using a standard 747-400.
In August 2006, a total of 627 Boeing 747-400 aircraft (all versions) were in airline service, with 46 further firm orders. Major operators include: Air China (12), Air India (12), Air New Zealand (8), All Nippon Airways (23), Asiana Airlines (14), Cathay Pacific (30, plus 6 on order), China Airlines (34, plus 2 on order), EVA Air (18), Japan Airlines (44), Korean Air (43), Malaysia Airlines (19), Qantas (30), Singapore Airlines (23), Singapore Airlines Cargo (15), Thai Airways International (18), Air France (21), British Airways (57), Cargolux (14, plus 2 on order), KLM Royal Dutch Airlines (25, plus 1 on order), Lufthansa (30), Virgin Atlantic Airways (13), Atlas Air (11), Northwest Airlines (16) and United Airlines (31). Some 24 airlines also operate the type, but in smaller numbers.[45]
The last to order was China Airlines in November 2002 and it was delivered to them on April 2005. It was the 1358th 747-400 (MSN33737/B-18215), the last passenger version to be built.[52] Production of the 747-400 passenger version was officially over on March 15, 2007.[53] However, thirty six 747-400F aircraft are still yet to be delivered.[53]

Main article: Boeing 747-8
Boeing announced a new 747 variant, the 747-8 (referred to as the 747 Advanced prior to launch) on November 14, 2005, which will use same engine and cockpit technology as the 787 (It was decided to call it the 747-8 because of the technology it will share with the 787 Dreamliner). Boeing claims that the new design will be quieter, more economical and more environmentally friendly.
The 747-8 is 251 feet long (76.4 m), and therefore would surpass the Airbus A340-600 to become the world's longest airliner once the aircraft is in service.
[edit] 747-8I
The passenger version, dubbed 747-8 Intercontinental or 747-8I, will be capable of carrying up to 467 passengers in a 3-class configuration and fly over 8,000 nmi to (15,000 km) at Mach 0.855. As a derivative of the already common 747-400, the 747-8 has the economic benefit of similar training and interchangeable parts. The 747-8I is also stretched to add more capacity/payload, which involved a lengthening from 232 to 251 feet (70.8 to 76.4 m). The 747-8I is scheduled to enter service in 2010.
As of March, 2007, there were a total of 24 firm orders for the Boeing 747-8I aircraft: 4 from Boeing Business Jets and 20 from Lufthansa.
[edit] 747-8F
Coincident with launching the 747-8I, Boeing announced a new freighter model, the 747-8F, which is to be a derivative to the 747-400ERF. The 747-8F is 251 feet (76.4 m) long and can accommodate 154 tons (140 tonnes) of cargo. To aid loading and unloading it features an overhead nose-door. It has 16 percent more payload capacity than the 747-400F and can hold seven additional standard pallets. It is a competitor to the Airbus A380 Freighter. The 747-8F is scheduled to enter service in 2009.
As of March 2007 there were 57 firm orders for the Boeing 747-8F aircraft, from Atlas Air (12), Nippon Cargo Airlines (8), Cargolux (13), Emirates air cargo (10), Volga-Dnepr (5), Guggenheim Aviation Partners (4) and Korean Air (5).[45]
[edit] Undeveloped variants
Boeing has studied a number of 747 variants which have not gone beyond the drawing board.
[edit] 747-300 Trijet
During the 1970s, Boeing studied the development of a shorter body, three-engined 747 to compete with the Lockheed L-1011 TriStar and the McDonnell Douglas DC-10, which were both smaller than the existing 747-100/-200 and had lower trip costs than the 747SP. The 747-300 Trijet would have been bigger than either of the competing trijets, with more payload, range and passenger capacity. The center engine would have been fitted in the tail with an s-duct intake similar to the L-1011’s. Wind tunnel testing showed that the upper deck interfered with the airflow into the center engine, and the design was not pursued. The 747-300 designation was later used for an improved 747-200 with a stretched upper deck.
[edit] 747-500X/-600X/-700X
Boeing announced the 747-500X/-600X at the 1996 Farnborough Airshow[56] to compete with the Airbus A3XX (later named A380). The aircraft would combine the 747's fuselage with a new 251 ft (77 m) span wing derived from that of the 777. Other changes included new engines similar to those being developed for the A3XX and an increasing in the number of tires from two to four on the nose landing gear and from 16 to 20 on the main landing gear.[57]
The 747-500X concept featured a slight stretch of the 747-400's fuselage and would have been able to carry 462 passengers over ranges of up to 10,000 miles (8,700 nmi or 16,100 km), with at least 10 tons of extra payload capacity. The 747-600X concept featured a greater stretch of the 747-400's fuselage, allowing it to carry 548 passengers over ranges of up to 8,900 miles (7,700 nmi or 14,300 km). If it had been developed, the 747-600 would have been the longest commercial airliner, at 279 ft (85 m), which is longer than the ICAO standard 80 m x 80 m box for large aircraft. While studies concentrated on these two derivatives, a third was also being considered. The 747-700X would have combined the wing of the 747-600X with a widened fuselage, allowing it to carry 650 passengers over the same range as a 747-400.
Because of the extent of modifications over the previous 747 models, in particular the new wing, the 747-500X/-600X would have cost in excess of $5 billion to develop. This proved too much, and Boeing was unable to attract enough interest to launch the aircraft.
[edit] 747X/X Stretch
As Airbus progressed with its A3XX study, in 1999 Boeing again offered the market a 747 derivative as an alternative. This was a more modest proposal than the previous -500X/-600X, which would retain the 747's overall wing design, albeit with a relofted center section increasing the span to 229 ft (70 m)[58]. Power would have been supplied by either the Engine Alliance GP7172 or the Rolls-Royce Trent 600, which were also proposed for the 767-400ERX. A new flight deck based on the 777’s would be used. The 747X concept featured a slight stretch over the 747-400’s fuselage, allowing it to carry 430 passengers over ranges of up to 10,000 miles (8,700 nm/16,100 km). The 747X Stretch would be extended to 263 ft (80 m) long, allowing it to carry 500 passengers over ranges of up to 9,000 miles (7,800 nmi/14,500 km). Both would feature an interior based on the 777’s signature architecture. A freighter model of the 747X was also envisaged.
Like the predecessor, the 747X family was unable to garner enough interest to justify production, and was shelved along with the 767-400ERX in March of 2001, when Boeing announced the Sonic Cruiser concept. While the design had been less costly than the 747-500X/-600X, it was criticized for not offering a sufficient advance from the existing 747-400. While the 747X did not make it beyond the drawing board, the 747-400X, which was being developed concurrently, did move into production to become the 747-400ER.
[edit] 747-400XQLR
Following the termination of the 747X program, Boeing continued to study improvements which could be made to the aircraft. The 747-400XQLR (Quiet Long Range) would have featured longer range than the 747-400ER, at 7980 nm (14,800 km), along with improvements to improve efficiency and reduce noise.[59] Improvements studied included raked wingtips similar to those used on the 767-400ER, and a sawtooth engine nacelle for noise reduction. While the 747-400XQLR did not move to production, many features were picked up for the 747 Advanced, which has now been launched as the 747-8.

* C-19 - the US military version of 747-100.
* VC-25 - the US military version of 747-200B. The US Air Force operates two in VIP configuration as the VC-25A. These are among the most famous 747 models with tail numbers 28000 and 29000. They are popularly known as Air Force One, although that is technically the call sign for any United States Air Force aircraft carrying the US President. Although based on the 747-200B, they contain many of the innovations introduced on the 747-400, such as an updated flight deck and engines.
* C-33 - the US military version of 747-400, which was intended to augment the C-17 fleet, but the plan was cancelled in favor of additional C-17 military transports.
* KC-33A - The 747 was also adapted as an aerial refueling tanker, and was bid against the DC-10-30 during the 1970s Advanced Cargo Transport Aircraft (ACTA) program which resulted in the KC-10A Extender. Before the Khomeini-led revolution, Iran bought four 747-100 aircraft with air refueling boom conversions to support a fleet of F-4 Phantoms. It is not known whether these aircraft remain usable as tankers. Since then other proposals have emerged for adaptation of later 747-400 aircraft for this role.[60]
* 747 CMCA - This variant was considered by the US Air Force as a Cruise Missile Carrier Aircraft during the development of the B-1 Lancer strategic bomber. It would have been equipped with up to 72 AGM-86 ALCM cruise missiles on rotary launchers. This was abandoned in favor of more conventional strategic bombers.
* E-4B - formerly known as National Emergency Airborne Command Post (referred to colloquially as "Kneecap"), now referred to as National Airborne Operations Center (NAOC).
* YAL-1 - the experimental Airborne Laser, a component of the National Missile Defense plan.
* Shuttle Carrier Aircraft - Two 747s were modified to carry the Space Shuttle. One is a 747-100 (N905NA), acquired in 1974 from American Airlines; the other is a 747-100SR (N911NA), acquired from Japan Airlines in 1988. It first carried a shuttle in 1991.
* T/Space has discussed the use of a 747 for its CXV space capsule proposal.
* A number of other governments also use the 747 as a VIP transport, including Bahrain, Brunei, India, Iran, Japan, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and United Arab Emirates. Recently, several new Boeing 747-8 have been ordered by Boeing Business Jet for conversion to VIP Transport for several unidentified customers.[61]

[edit] Incidents
* The first crash of a 747 took place in November 20, 1974 when Lufthansa Flight 540 crashed in Nairobi killing 59 people.
* The Tenerife disaster on March 27, 1977 claimed a total of 583 lives when two 747s collided in heavy fog at Tenerife Airport. This is the highest death toll in any aviation accident in history.[63]
* An Air India Flight 855 Boeing 747 crashed into the sea off the coast of Mumbai (Bombay) on New Year's Day, 1978. All passengers and crew were killed. Many residents of sea-front houses in Mumbai witnessed the incident.
* British Airways Flight 9, on June 24, 1982, flew into a volcanic dust cloud, resulting in all four engines failing. After exiting the cloud, three engines continued working, allowing the plane to land safely in Jakarta.
* Korean Air Lines Flight 007 was a 747-230B which was shot down by the Soviet Air Force on September 1, 1983. All 269 passengers and crew aboard were killed.
* China Airlines Flight 006 - February 19, 1985
* Air India Flight 182 was a 747-237B that exploded on June 23, 1985. All 329 on board were killed. Up until September 11, 2001, the Air India bombing was the single deadliest terrorist attack involving aircraft.
* The Lockerbie bombing on December 21, 1988 was a Pan Am 747-100.
* On August 12, 1985, the Japan Airlines Flight 123 (a 747SR Short Range) was lost when most of its vertical stabilizer fell off while at cruising altitude. The pilots kept it in the air for just over thirty minutes, but eventually crashed, causing 520 fatalities. It is the worst single-aircraft disaster in aviation history.[64]
* On 28 November 1987, South African Airways Flight 295, a Boeing 747-244B Combi Helderberg en route from Taipei to Johannesburg crashed into the ocean off Mauritius after an in-flight fire in the rear cargo hold resulted in loss of control and destruction of the aircraft. All 159 people on board were killed.
* United Airlines Flight 811, a Boeing 747-122, suffered in February 24, 1989 an explosive decompression shortly after takeoff from Honolulu, Hawaii, caused by a cargo door which burst open during flight. Nine passengers were sucked out of the plane, but the pilots managed to land safely at Honolulu.
* El Al Flight 1862 was a 747-200F which crashed shorly after take-off from Amsterdam Schiphol on October 4, 1992. Engines no. 3 and 4 detached shortly after take-off and as a result the flight crew lost control and the crippled 747 crashed into the Klein-Kluitberg apartments in Bijlmermeer at high speed. The sole passenger and all three crew were killed as well as 39 on the ground.
* TWA Flight 800, a 747-131, exploded during climb from New York's John F. Kennedy Airport on July 17, 1996, bound for Charles de Gaulle Airport in Paris, killing all 230 people.
* On August 6, 1997, Korean Air Flight 801 crashed before landing at Antonio B. Won Pat International Airport, Guam, killing all but 26 of its passengers.
* On 31 October 2000, Singapore Airlines Flight 006, a Boeing 747-400 flying on a Singapore to Los Angeles via Taipei route rammed into construction equipment while attempting to take off from a closed runway at Chiang Kai Shek International Airport, caught fire and was destroyed, killing 79 passengers and three crew members. The accident prompted the airline to change the flight number of this route from 006 to 030 and to remove the "Tropical Megatop" livery on the accident aircraft's sister ship.[65]
* China Airlines Flight 611, a 747-209B, broke-up mid flight on May 25, 2002, en route to Hong Kong International Airport, Hong Kong from Chiang Kai Shek International Airport in Taipei, Taiwan. All on board lost their lives.
Very few crashes have been attributed to design flaws of the 747. The Tenerife disaster was a result of pilot error, ATC error and communications failure, while Japan Airlines Flight 123 was the consequence of improper aircraft repair. United Airlines Flight 811, which suffered an explosive decompression mid-flight on February 24, 1989, subsequently had NTSB issuing a recommendation to have all similar 747-200 cargo doors modified. TWA Flight 800, a 747-100 that exploded mid-air on July 17, 1996, led to the Federal Aviation Administration proposing a rule requiring the installation of an inerting system in the center fuel tank for most large aircraft.
As of May 2006, there were a total of 44 hull-loss occurrences involving 747s, with 3707 fatalities.
[edit] Facts and Figures
* To enable easy transportation of spare engines between sites by airlines, early 747s include the ability to attach a non functioning fifth-pod engine under the port wing of the aircraft, between the nearest functioning engine and the fuselage.[66]
* On 24 May 1991 an El Al Boeing 747 airlifted a record-breaking 1,087 passengers – Ethiopian Jews flying from Addis Ababa to Israel as part of Operation Solomon. The passenger count became 1,088 when a baby was born in-flight.[citation needed]
* The 747 has appeared as a setting for a number of films. The most well known of these is the Airport series of disaster films. Other films using a 747 include Snakes on a Plane, Air Force One, Turbulence and Executive Decision.
