The Boeing 747 has more than one aisle, which means it is a wide-body aircraft. It is often called the Jumbo Jet or Queen of the Skies. The Boeing 747 is one of the easiest planes in the world to recognize.[4] It was the first wide-body aircraft ever made. The first type of 747 was two and a half times the size of the Boeing 707.[5] The Boeing 747 made its first flight for an airline in 1970. The 747 could carry more people than any other aircraft for 37 years, until the Airbus A380 was made.[6]

The 747 is a double deck plane. It can carry people, cargo and many other things. Boeing designed the 747's upper deck to be a first class lounge or just extra seats. They also designed the upper deck so that the aircraft could be changed into a cargo plane easily. This was done by removing seats and putting in a cargo door at the front of the plane. Boeing did this because they thought that supersonic airliners would become much more popular than the 747 and other subsonic airliners. However, they thought that subsonic cargo planes would always be popular.[7] It was thought that the 747 would become unpopular after 400 were sold.[8] However, 1,000 planes had been made by 1993, so it stayed popular.[9] By September 2012, 1,448 aircraft had been built. 81 747-8s were still waiting to be built.[2]

The 747-400 is one of the fastest airliners being used today. It usually flies at Mach 0.85–0.855 (up to 570 mph, 920 km/h). It can fly for 7,260 nautical miles (8,350 mi or 13,450 km).[10] The last version of the 747, the 747–8, ended being made in December 2022.

The 747 will be replaced by the Boeing Y3 (part of the Boeing Yellowstone Project) eventually.

Development

Background

In 1963, the United States Air Force began to look for a very big plane to transport things. At that time, they were using the Lockheed C-141 Starlifter. However, the Air Force thought that a much bigger plane which could carry more cargo was needed. The Air Force called the big plane the CX-Heavy Logistics System (CX-HLS). It needed to be able to carry Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value). of cargo and travel at Mach 0.75 (Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value).). It also had to be able to fly for Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value). while carrying Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value). of cargo. The cargo bay had to be Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value). wide, Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value). high and Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value). long. There had to be doors for the bay at the front and the back of the plane.[11]

The Air Force also wanted the plane to have only four engines. This meant that new engines had to be made. On May 18, 1964, Boeing, Douglas, General Dynamics, Lockheed and Martin Marietta designed a plane. General Electric, Curtiss-Wright and Pratt & Whitney designed the engines. The Air Force liked Boeing, Douglas and Lockheed's designs. They also liked General Electric and Pratt & Whitney's engine designs.[11]

In 1965, Lockheed's plane and General Electric's engines were used for the C-5 Galaxy. At that time, it was the biggest military cargo plane in the world.[11]

Airliner

The idea for the 747 was thought of in the 1960s.[12] Jets like the Boeing 707 and Douglas DC-8 had made it easy to travel long distances.[12][13] Juan Trippe from Pan American World Airways (Pan Am), asked Boeing to build a plane which was more than two times bigger than the Boeing 707. At this time, airports were very busy. Trippe thought that a big plane could help make them quieter.[14]

In 1965, Joe Sutter was told to design this new plane. It was called the 747.[15] Sutter asked Pan Am and other airlines what they would like from the plane. At the time, it was thought that supersonic aircraft would replace the 747.[16] Because of this, Boeing made the 747 so that it could easily be turned into a cargo plane if the passenger version became less popular.

In April 1966, Pan Am bought 25 747-100 planes. The order cost US$525 million. Since Pan Am was the launch customer,[1][17] Pan Am had a big say in the design and making of the 747. No other airline before then or since then has been able to have so much influence over a plane.[18]

Designing

The design that Boeing made for the Air Force in 1963 was not used for the 747. However, Boeing made some new things for the Air Force which were used in the 747.[19] The first design had two full decks.[20] However, in 1966, this was changed to only one deck.[1] The cockpit was put above the deck, which made a "bulge".[21] There was a small space behind the cockpit which people could sit in. At first, it was a "lounge" area with no seats.[22]

 
The Pratt & Whitney JT9D turbofan engine was made for the 747.

Planes as big as the 747 needed high-bypass turbofan engines.[23] High-bypass turbofans can produce twice the power of turbojets, and also use a lot less fuel. General Electric made the first of these engines. However, it was making the engines for the C-5 Galaxy. It did not make engines for airliners until later.[24][25] Pratt & Whitney was also working on this type of engine. In 1966, Boeing, Pan Am and Pratt & Whitney designed a new engine, the JT9D, for the 747.[25]

Boeing used some special devices to make the plane make more lift. This was done so that the 747 could take off from shorter runways. The 747 has a lot of flaps on the wing.[26] The flaps make the wings bigger by 21 percent. They also make 90 percent more lift when they are used.[27]

Boeing tried to give the 747 to Pan Am by the end of 1969. This meant that Boeing only had 28 months to design the aircraft.[28] The people who worked on the 747 had the nickname "The Incredibles".[29]

Factory

 
747s being made at the Boeing Everett Factory

Boeing did not have a factory big enough to make the new plane. Boeing thought about putting their factory in 50 different cities.[30] They eventually decided to build their factory in Seattle, near Everett, Washington.[31] Boeing bought the factory in June 1966.[32]

Designing the 747 was very difficult. Building its factory was also not easy. Boeing's president, William M. Allen, asked Malcolm T. Stamper to be in charge of the building of the Everett factory. He was also asked to begin building the 747.[33] The factory is the biggest building ever built (by volume). It has been made bigger many times so that Boeing can build even bigger planes.[31]

Development and testing

Before the first 747 was put together, parts and systems were being tested. In one important test, 560 volunteers evacuated a replica of a 747 cabin using the emergency chutes. The first evacuation took two and a half minutes. However, the FAA says that the maximum time for an evacuation is 90 seconds. Many of the volunteers were hurt. More evacuations happened, and they eventually reached the 90 seconds. However, they also caused a lot of injuries. Evacuating from the top deck of the plane was difficult. Instead of using the usual slides, the volunteers had to leave the plane using a harness.[34] The plane's taxiing also had to be tested. Boeing made "Waddell's Wagon" (named after a 747 test pilot, Jack Waddell) to train the pilots. "Waddell's Wagon" was a replica of a 747 cockpit which was put on the roof of a truck. This helped pilots to learn how to taxi the plane.[35]

On September 30, 1968, the first 747 was finished. People from the 26 airlines that had ordered the 747 were also there.[36] The 747 first flew on February 9, 1969. Its pilots were Jack Waddell and Brien Wygle.[37][38] There was a small problem with the flaps, but the 747 handled well.

The testing was delayed because of some problems with the JT9D engines. For example, the engines stalled if the throttles were moved too quickly.[39] This meant that 747s could not be delivered for many more months. 20 planes were stuck at the factory while they were waiting on engines.[40] On December 13, 1969 the test plane was being taken to have some changes made to it. The pilot, Ralph C. Cokely landed too early and did not reach the runway. One of the landing gears was ripped off, and two of the engines were damaged.[41][42] However, Boeing took the 747 to the 28th Paris Air Show in mid-1969. There, the public saw the 747 for the first time.[43]

Designing the 747 and building the new factory cost a lot of money. This meant that Boeing had to borrow a lot of money from a bank. Just before the first aircraft was finished, Boeing had to keep asking for more money. If Boeing was not given this money, the company could have collapsed.[17][44] Boeing was in over $2 billion in debt. Allen said, "It was really too large a project for us."[45]:303 However, the 747 program was a success. Boeing was the only company to make very big planes for many years.[46]

Use by airlines

The very first time a 747 was used by an airline was on January 22, 1970. Pan Am used it to fly from New York to London.[47] The flight was supposed to happen on the evening of January 21. However, the engines on the aircraft overheated. Pan Am had to find another plane, which took six hours.[48]

 
On the 747-100 and 747–200, a spiral staircase was used to go from the bottom to the upper deck

The 747 did quite well when it first began to be used. Some people thought that airports would not be able to handle such a big plane. However, they could.[49] There were some problems, but they were quite small and they were fixed quickly.[50] After Pan Am began to use the plane, other airlines began to use their 747s.[51] Boeing thought that a lot of 747s would be sold because airlines wanted a plane which could fly for a long time, not because it was so big.[52][53]

The recession of 1969-1970 was very bad for Boeing. For over a year after September 1970, it only sold two 747s. None were sold to an American airline for over three years.[45]:302 Some airlines did not have enough passengers to fly the 747. Therefore, they replaced them with the McDonnell Douglas DC-10 and Lockheed L-1011 TriStar.[54] American Airlines eventually only used its 747s to carry cargo. In 1983, AA gave its 747s to Pan Am. Pan Am gave American Airlines some smaller planes.[55] Delta Air Lines also stopped using its 747s after many years.[56] Delta would later merge with Northwest Airlines, which operates 747s.[57]

 
Later 747s had a longer deck at the top

Flights which landed in smaller cities became quite usual in the 1980s. This was bad for the 747.[58] However, many airlines still used the 747 to fly across the Pacific.[59]

Upgrades made to the 747

The first type of 747 was called the 747–100. After this, Boeing made the −100B, which has a higher MTOW (maximum takeoff weight), and the −100SR (Short Range). The -100SR could carry more passengers.[60] A higher MTOW means that the plane can carry more fuel and fly further.[61] In 1971, Boeing made the −200. It had better engines and a higher MTOW. Airliner and cargo versions of the −200 were made.[60] The 747SP (special performance) was also made. It began being used in 1976.[62]

In 1980, Boeing made the 747–300. The first 747-300 was made in 1983. Its upper deck was longer, it flew faster and it could hold more passengers. The −300 was first called the 747SUD for "stretched upper deck". Then it was called the 747-200 SUD,[63] then the 747EUD, and finally it was called the 747–300.[64]

 
The 747-400 began being used in 1989. Air New Zealand was one of the first airlines to use it.

In 1985, Boeing began to design the 747-400.[65] This type has a glass cockpit. This meant that only two people were needed in the cockpit.[66] It also had new engines and a new cabin. The workers who made the 747-400 were not very experienced and Boeing wanted them to work for longer than they needed to. This meant that there were some problems with the first 747-400s.[1] The −400 began being used by airlines in 1989.[67]

In 1991, 1,087 passengers were taken to Israel on a 747. This was a part of Operation Solomon.[68] The Antonov An-225 cargo transport is the world's biggest plane. The Hughes H-4 Hercules has the biggest wingspan, but it only flew once.[69]

More developments

Since the 747-400 was made, many more types of 747 have been suggested. Boeing said that they would make the 747-500X and -600X in 1996.[70] These new planes would have cost more than US$5 billion to design and make.[70] Airlines did not like it enough, so Boeing decided not to make the planes.[71] In 2000, Boeing said it would make a 747X to rival the Airbus A3XX. However, airlines did not like the 747X enough, so it was cancelled. A year later, Boeing began concentrating on the Sonic Cruiser.[72] The Sonic Cruiser was stopped, so Boeing then focused on the Boeing 787 Dreamliner.[73] Some of the ideas that Boeing had for the 747X were used on the 747-400ER.[74]

In 2004, Boeing said that it might work on the 747 Advanced. Boeing decided to go ahead with this. The 747 Advanced used some things from the 787 to make the 747's design more modern. The 747 was the world's biggest passenger plane until the Airbus A380 was finished in 2007.[75]

On November 14, 2005, Boeing said it had changed the name of the 747 Advanced to the Boeing 747-8.[76] The last 747-400s were made in 2009.[77] On February 8, 2010, the 747-8 Freighter made its first flight.[78] Cargolux got the first 747–8 in 2011.[79][80] Eventually, the 747 will be replaced by "Y3".[81]

Design

 
Boeing 747-200 design.

The Boeing 747 is a big, wide-body airliner. It has four engines on the wings, and the wings are swept at 37.5 degrees, so the 747 can fly very fast.[21] The sweep also means that the 747 does not need any special hangars.[1][82]

Since the cockpit is above the main deck, it makes a "hump", and because it is so high, the plane can have a cargo door installed at the front.[21]

The 747-100 can fly for 5,300 nautical miles (6,100 mi, 9,800 km), and the 747-8i can fly for 8,000 nmi (9,200 mi, 14,815 km).[83][84]

The 747 has special flaps, which allow the 747 to fly slowly and land on normal runways.[85] A 747 can carry a fifth engine on the wing, but it cannot be used.[86][87]

Types of Boeing 747

The 747-100 was the very first type of 747, which was made in 1966. The 747–200, the next version, was made in 1968. The 747-300 was made in 1980 and the 747-400 was made in 1985. The newest version, the 747–8, was announced in 2005. These types also have smaller sub-types. The International Civil Aviation Organization (ICAO) names these planes by combining the model number of the plane with its type number. For example, the 747-100 is "B741" and the 747-400 is "B744".[88]

747-100

 
Pan Am was the first airline to use the 747.

The first 747-100s had six windows on the upper deck. Later, airlines began to use the upper deck to hold more people instead of using it as a lounge. Boeing then made an upper deck with ten windows. Some −100s had the new ten-window upper deck installed after the plane was made (retrofitted).[89] The −100 had Pratt & Whitney JT9D-3A engines. Boeing did not make a freighter version of the 747–100, but some airlines have turned some 747-100s into freighters.[90] 167 747-100s were made.

747-100SR

After Japanese airlines requested an aircraft to fly routes between major cities in Japan, Boeing produced the -100SR. This model flies shorter distances, but is able to carry more passengers. The first -100SR started flying with Japan Air Lines (JAL) on October 7, 1973.[91] The -100SR had four General Electric CF6-45A2 or Pratt & Whitney JT9D-7A engines. A total of 7 -100SR were produced.

Later, Boeing designed a type of -100SR with the ability of taking off with greater weight. This was the -100BSR. It was first delivered to All Nippon Airways (ANA) on December 21, 1978. 20 -100BSR were delivered to JAL and ANA.

In 1986, 2 -100BSR with stretched upper deck (SUD) from the -300 series were delivered to JAL. It was the last -100SR/BSR ever built. The last delivery was to JAL, in September 1986.[2] There were a total of 29 -100SR/BSR made.[92]

747SP

SyrianAir 747SP

The 747SP (SP means special performance) is designed as Pan Am and Iran Air both wanted a wide-body plane that can fly long distances; from New York to the Middle East (for Pan Am) and Tehran to New York (for Iran Air). The first 747SP was produced on May 19, 1975. Its first flight was on July 4. On this flight, it flew at a top speed of Mach 0.92 (1,127 kilometres per hour or 700 miles per hour). It started flying people on April 25, 1976, after being delivered on March 5.[91] Now, it is not often used. A total of 45 747SP were made and used by airlines like Qantas, China Airlines, Air China, and South African Airways.[93]

747-200

After the -100 were made, Boeing started making -200. The -200 has a longer range, but still carries the same number of people. This is because airlines said the -100 could not fly long distances. The -200 is made in passenger type (-200B), freighter type (-200F), Combi type (A plane that carries both cargo and people; -200M) and convertible type (a plane that can be easily changed to carry cargo; -200C).

The first -200B was finished on September 10, 1970 before its first flight on October 11 and finally, it started being used by KLM. Boeing then started making the other types of -200. The -200F first flight was on November 30, 1971, 7 days after it was finished. It was then delivered to Lufthansa.

The -200C first flew on March 23, 1973 before being delivered to World Airways in May the same year. Finally, the -200M had its first flight on November 11, 1974 before being delivered to Air Canada.

There was a total of 393 -200 series ever made, which includes 225 -200B, 78 -200M, 73 -200F, 13 -200C and 4 military.[92]

747-300

The 747-300 is a stretched upper deck version of the 747–200. It was designed to fit more passengers on the upper deck. The 747-300 also has updated General Electric CF6-80C2 engines. Otherwise, there are not many differences between the 747-200 and 747–300. The 747-300 has a length of 231 feet 10 inches and a wingspan of 195 feet 8 inches.[94]

747-400

The 747-400 was the next-generation Boeing 747 introduced in 1989. It is the best-selling variant of the Boeing 747. It includes improvements over the 747-300 including new engines, and new winglets, which improve fuel efficiency. Its length is the same as the 747-300 but the wingspan has been increased to 211 feet 5 inches. The 747-400 retains the same longer upper deck as the 747-300 (excluding freighter versions), and came in six variants: the 747–400, 747-400F, 747-400M, 747-400D, 747-400ER, and the 747-400ERF.

747-8

The last variant of the Boeing 747 was announced in 2005 and released in 2011. It includes a longer stretched upper deck, a new Boeing Sky Interior, an updated flight deck, new wings based on ones from the Boeing 787 Dreamliner, and new GEnx turbofan engines. It totals 250 feet in length, making it the longest commercial passenger jet ever built. The 747-8 comes in two variants: 747-8I and 747-8F (freighter).

Accidents and Problems

  • March 27, 1977 - the deadliest aviation accident in history occurred when KLM Flight 4805 collided on the runway with Pan Am 1736 in heavy fog at Tenerife Airport, resulting in 583 fatalities. Both aircraft were 747s. The 61 survivors were all from the Pan Am 747. The Pan Am aircraft was the first 747 to enter commercial service.
  • September 1, 1983 - Korean Air Lines Flight 007 from New York City to Seoul via Anchorage, was shot down just west of Sakhalin Island by the Soviet Air Force, killing all 269 passengers and crew aboard.
  • June 23, 1985 - Air India Flight 182 en route from Montreal to New Delhi, a bomb exploded. causing the aircraft to explode and crash off the southwest coast of Ireland, killing all 329 on board. Until the September 11 attacks of 2001, the Air India bombing was the single deadliest terrorist attack involving aircraft. It remains the "worst mass murder in Canadian history."
  • August 12, 1985 - Japan Airlines Flight 123 crashed when the rear pressure bulkhead of a 747SR flying from Tokyo to Osaka failed at cruising altitude, severing the aircraft's vertical stabilizer. The pilots kept it in the air for 32 minutes, but it eventually struck Mount Takamagahara and crashed. Of the 524 people on board, only four passengers survived, making it the deadliest-ever single-aircraft accident. The accident was caused by Boeing improperly repairing the tail strike suffered by the same aircraft seven years earlier.
  • November 28, 1987 - South African Airways Flight 295 en route from Taipei to Johannesburg, crashed into the ocean off Mauritius after a fire broke out in the rear cargo hold, damaging vital control systems. All 159 people on board died.
  • December 21, 1988 - Pan Am Flight 103 disintegrated in midair after a bomb in the luggage hold exploded; the wings, with their tanks full of fuel, landed on Lockerbie, Scotland. All 259 people on board and 11 people in Lockerbie died. A Libyan national was eventually convicted at a Scottish court sitting in the Netherlands of murder in connection with the bombing.
  • February 24, 1989 - United Airlines Flight 811 which suffered an explosive decompression in mid-flight. The Plane land safety. But of the 355 people on board 9 passengers died.
