HistoryThe 707's jet speed, long range, high seating capacity and operating economicsrevolutionised airliner travel when it was introduced into service in 1958. The 707also laid the foundations forBoeing's dominance of the jet airliner market.

Recognising the jet engine's potential for commercial aviation,Boeing (at greatfinancial risk) decided to develop a jet powered transport that could fulfil militarytanker transport roles but be easily adapted to become an airliner. The resultingprototype, known as the 367 Dash 80, flew for the first time on July 16 1954.Impressed, the US Air Force ordered a larger version, with a wider fuselage (12 ft,vs 11 ft for the Dash 80) into production as the KC-135 tanker/transport (more than800 were built). At first,Boeing wanted to sell the same size aircraft to the airlines,but the airlines insisted on an even larger airplane, which Douglas promised to

build (this became the DC-8). Boeing finally relented, designing the 707 as a longeraircraft with a slightly wider fuselage (12 ft 4 in).

The first production 707 (a 707-120 for Pan Am) flew on December201957, andentered service later the following year. Developments of the 707-120 include thesimilar707-220, the shorter138 for Qantas, and the stretched 707-320, which flewin July 1959. The 707-120 and 320 were later reengined with JT3D turbofans (inplace of the original JT3 and JT4 turbojets) to become the 707-120B, and the 707-320B respectively. The 707-320C was a convertible model, the 707-420 waspowered by RollsRoyce Conways, while the proposed CFM-56 powered 707-700upgrade was flight tested in the late 1970s but never entered production.

Most civil 707s in service today have been converted to freighters, while a numberare used as corporate transports.

Many air forces have bought 707s, new or converted second-hand aircraft, forgeneral transport, aerial refuelling, and electronic warfare. The E-3 Sentry is adedicated airborne warning and control system (AWACS) platform with a largerotodome above the fuselage. The E-6 Mercury performs the TACAMO (TakeCharge and Move Out) role with the US Navy, maintaining communication with the

ballistic missile submarines. The E-8 J-Stars (Joint Surveillance Target AttackRadar System) performs the battlefield control role. Other military 707s receivedthe designations C-137, or C-18, but many others have no special militarydesignation. Copyright Airliners.net, some information CopyrightAerospace Publications

The 720 is a smaller capacity, lighter, medium range variant of the 707, given itsown model number to indicate significant engineering changes.

Introduced in 1959, the 720 (originally designated 707-020) retained the samebasic structure as the 707-120, but was 2.54m (8ft 4in) shorter, which reducedseating to 112 (38 + 74) in a typical two class arrangement. Other changes weremade to the wing which introduced full span leading edge flaps, while a glovebetween the inner engines and the fuselage increased wing sweep and wing area

and decreased the wing's thickness/chord ratio. The changes to the wing made itmore aerodynamically efficient, permitting higher cruising speeds and loweredminimum speeds (which aided field performance).

Like the early 707s the first 720s had JT3C turbojets, although less powerfulmodels lacking water injection because of the 720's lighter weight. Comparedwith the 707-120 the 720 also had reduced fuel capacity and a lower max takeoffweight. But many components were interchangeable between the 720 and 707,while inside the cabin the 720 and 707 shared the same passenger interior andflightdeck.

The initial 720 (bound for launch customer United) first f lew on November231959. Certification was awarded on June 301960, and entry into service withUnited Airlines was on July 5 that year.

The availability of the far more fuel efficient Pratt & Whitney JT3D turbofan

resulted in the 720B, which was powered by either JT3D1s or 3s. First flight ofthe 720B was on October 6 1960, with certification awarded on March 3 1961.The 720B also featured a higher maximum zero fuel weight (significantly boostingpayload/range) and an increased max takeoff weight due to the heavier turbofanengines.

Major720 operators included American Airlines (a number of its 720s wereconverted to 720Bs with turbofan engines), United, Continental, Eastern,Northwest Orient and Western, while operators outside the US includedLufthansa and Avianca.

Today (early 2002) three 720s are believed to be in use as corporate transports,and two are used by Pratt & Whitney as engine testbeds.

HistoryThe 727 short to medium range trijet is the world's second most successful jetairliner built.

Initial design studies began in 1956, although for a time it appeared that a newshort/medium range airliner would not be built at all due to Boeing's financialposition before sales of the 707 had taken off. Boeing persisted however andserious development of the 727 beginning in June 1959. The program waslaunched on the strength of orders for 80 from Eastern and United in 1960.

The resulting Boeing Model 727 pioneered the rear trijet configuration, withpower from three specially designed Pratt & Whitney JT8D turbofans (althoughRollsRoyce Speys were originally considered). The trijet design was settledupon as it gave the redundancy of three engines, better climb performance thana twin and improved operating economics over a four engine jet. The 727 alsointroduced an advanced wing design with the first airliner application of tripleslotted Krueger flaps. The 727 retained the 707's fuselage cross section, but

with a redesigned smaller lower fuselage due to the need to carry less baggageon shorter range flights, and it has limited parts commonality with the 707 and720. The 727 was also the first Boeing airliner to feature an APU (auxiliarypower unit).

The prototype 727 first flew on February 91963, with certification granted inDecember that year. The first 727 entered service with Eastern Airlines onFebruary 9 the following year.

Development of the initial 727-100 resulted in a small family of sub variants,including higher gross weight options for the basic passenger carrying 727, the

HistoryThe 727-100 had been in service barely a year when Boeing began seriousconsideration of a stretched, greater capacity development.

This resulted in the 727-200, which Boeing announced it was developing inAugust 1965. The 727-200 was essentially a minimum change development ofthe 100, the only major change being the 6.10m (20ft) fuselage stretch, whichincreased maximum seating to 189 passengers. The 727-200's stretchconsisted of two 3.05m (10ft) plugs, one forward and one rear of the wing.

Otherwise the 727-100 and 200 shared common engines, fuel tank capacity andthe same maximum takeoff weight.

The first flight of the 727-200 occurred on July 271967, with certificationgranted in late November that year. The -200 was placed into service by launchcustomer Northeast Airlines (this airline was later acquired by Delta) thefollowing month, by which time total 727 orders for both models had exceeded500.

The 727-200 helped broaden the sales appeal of the 727 considerably andsnared significant sales. However the 200 was restricted by its relatively shortrange, due to it having the same fuel capacity as the 727-100, so Boeingdeveloped the increased range Advanced 727-200. First flown in March 1972changes introduced on the Advanced model included increased fuel capacity,and thus range, the option of more powerful engines, quieter engine nacelles

and strengthened structure. The Advanced remained the primary727-200

production model until production ceased in 1984.

The 727-200 remains popular with passengers and pilots but it does not meetStage 3 noise requirements. To overcome this a number of hushkit programsare on offer while Valsan converted 23 727s to its Stage 3 compliant Quiet 727standard (before the company collapsed). This retrofit included installing JT8D-217s on the outer pylons and acoustic treatment of the centre engine. Other727s have been fitted with winglets for improved performance.

The 737-100 made its first flight on

April 91967 and entered service inFebruary 1968 with Lufthansa,while the last of 30 built wasdelivered to Malaysia-SingaporeAirlines in October1969.

By this time however the largercapacity 1.93m (6ft 4in) stretched737-200 was in service after it hadmade its first flight on August 81967. First delivery, to United, wasthat December.

Developments of the -200 includethe -200C convertible and quick

change -200QC, while anunprepared airfield kit was alsooffered. The definitive Advanced737-200 appeared in 1971,featuring minor aerodynamicrefinements and otherimprovements.

Sales of the 737-200 far exceededthat of the shorter-100 and the737-200 remained in productionuntil 1988, by which time it hadbeen superseded by the improved737-300, after1114 had been built.Many have been fitted with Stage 3

engine hushkits, and a number ofpassenger aircraft have beenconverted with cargo doors.

The USAF ordered 19 asnavigation trainers, and some werelater converted to standardtransport aircraft as CT-43A. A fewother air forces received 737-200sto serve in general transport,surveillance or VIP transport tasks.

HistoryThe 737-300 is the first of the threemember second generation CFM56powered 737 family, which alsocomprises the stretched 737-400 andshortened 737-500. The success of thesecond generation Boeing 737 familypushed sales of the mark to over 3000,a record for a commercial jetliner.

Boeing announced it was developingthe 737-300 in March 1981. This newvariant started off as a simple stretchover the 737-200 but Boeing decided toadopt the CFM International CFM56high bypass turbofan (jointly developedby General Electric and SNECMA) toreduce fuel consumption and complywith the then proposed InternationalCivil Aviation Organisation Stage 3noise limits.

Other internal changes includematerials and systems improvementsfirst developed for the 757 and 767programs, including an early generationEFIS flightdeck (with four colour CRTscreens).

The 737-300 flew for the first time onFebruary 24 1984, while first deliverieswere from November1984. Since that

time well over1000737-300s havebeen sold and it forms the backbone ofmany airlines' short haul fleets.

HistoryBoeing announced it was developing anew higher capacity version of the fastselling 737-300 in June 1986.

The new aeroplane, the 737-400, wasdeveloped as a 150 seat class 727replacement. Although Boeing had initiallydeveloped the 180 to 200 seat 757 toreplace the successful 727, there still

existed a considerable market for a neardirect size replacement for the populartrijet. By developing the 737-400 as aminimum change stretch of the 737-300,Boeing was also able to offer considerablecommonality, and thus cost, benefits tooperators already with the 737-300, and toa lesser extent, the 737-200 in their fleets.

The major change of the 737-400 over thesmaller 300 is a 3.05m (10ft 0in) fuselagestretch, consisting of a 1.83m (6ft 0in)stretch forward and a 1.22m (4ft 0in) plugrear of the wing. The stretch increasesmaximum passenger seating to 188. To

cope with the increased weights, morepowerful CFM56s are fitted. Otherchanges are minor, such as a tail bumperfitted to protect against over rotation attakeoff, something that could havebecome a problem due to the increasedfuselage length.

A higher gross weight longer rangeversion is offered. It features increasedfuel capacity, and strengthened

the 400 has proven the most successfulmember behind the 300, its larger capacityand transcontinental US range meaning ithas found a very useful market forBoeingas a 727 replacement. However the 737-400 does face stiff competition from thesimilar size Airbus A320, which has higherlevels of technology, longer range and isfaster (but is also heavier).

HistoryThe 737-500 is the shortest and smallest member of the secondgeneration 737-300/-400/-500 family, and the last to be developed.

When the new stretched 737-300 first appeared it was intended tosupplement, rather than replace, the 737-200. However the evolutionof the 737-300 into a family of models led to the development of anew model comparable in size to the 737-200, but offering better fueleconomy and extensive commonality with the 737-300 and -400

models. This was the 737-500, known before its May 1987 formallaunch as the 737-1000.

Like the preceding 737-300 and 737-400, the 737-500 is powered byCFM International CFM56s turbofans, in this case either 82.3kN(18,500lb) CFM563B1s or 89.0kN (20,000lb) CFM56-3C-1s. All threesecond generation 737 models share extensive systems andstructure commonality, and a common aircrew type rating. Thesebenefits offer real cost savings to an airline with two or more variantsof the family in its fleet.

The 737-500 is 31.01m (101ft 9in) in length, comparable to the 737-200's 30.53m (100ft 2in) length, and as such is a viable directreplacement for the earlier type. Like the 300 and 400, a higher grossweight longer range version is offered, featuring auxiliary fuel tanks

and uprated engines.The 737-500's first flight occurred on June 301989, FAA certificationwas awarded on February 121990, with service entry later that samemonth.

The 737-500's main appeal is for operators of large 737-400 and737-300 fleets, as because the 500 is a shortened development ofthe 300, it still carries much of the structural weight needed for thehigher weight models. This makes it less efficient than if it wasdesigned specifically for its size category, however for operators oflarge 737-300/400 fleets, the extensive commonality benefits more

HistoryThe 737-600 and -700 are the smaller members ofBoeing's successful NextGeneration 737-600/700/800/900 family.

Among the many changes, the Next Generation 737s feature more efficientCFM56-7B turbofans. The CFM56-7 combines the core of the CFM56-5 withthe CFM56-3's low pressure compressor and a 1.55m (61in) fan. The 737'snew wing has greater chord, span and wing area, while the tail surfaces arealso larger. The 2.4m (8ft) high winglets first developed for the BoeingBusiness Jet development are now offered as an option on the 737-700 (and -800).

The new engines and wings allow the 737 to cruise at Mach 0.78 to Mach0.80, while the larger wing allows greater fuel tankage and transcontinentalUSA range. Other features include a 777 style EFIS flightdeck with six flatpanel LCDs which can be programmed to present information as on the 777 oras on the 737-300/400/500 series, allowing a common pilot type rating for thetwo 737 families.

The improved Next Generation Boeing 737 family (originally covered by the737X designation) was launched in November1993. The 737-700 was the firstmember of the new family to be developed, and is based on the 737-300,

The C-40 first flew onApril 172000. The naval aircraft can be converted to carry 121 passengers, or3 pallets of cargo plus 70 passengers, or 8 pallets of cargo only. These aircraftare currently (2002) based at Naval Air Station Fort Worth, Texas (VR-59) andNaval Air Station Jacksonville, Florida (VR-58).

The US Air Force has bought two ex-FordairBBJs, which are designated C-40B.

HistoryThe Boeing Business Jet - orBBJ - is a long range corporate jet

development of the 737-700 and -800.Boeing Business Jets is a joint venture formed by Boeing and GeneralElectric in July 1996 to develop and market a corporate version of thepopular737 airliner, initially focusing on the 737-700 based BBJ (or737-700BBJ). The first BBJ rolled out from Boeing's Renton plant on August 111998and flew for the first time on September 4 that year. On October 30 the USFAA awarded certification to the developed 737-700 airframe on which theBBJ is based. The first completed BBJ was delivered on September 4 1999.

HistoryBoeing's Next Generation 737-800 and 737-900 are the largest members of

the strong selling 737 family. Unlike the other Next Generation 737s, the -800 and -900 introduce new fuselage lengths, extending 737 single classseating range out to 189, compared with 100 in the original 737-100.

Like the -600 and -700, the -800 and -900 feature the Next Generationimprovements including more efficient CFM56-7B turbofans, the new wingwith greater chord, span and wing area, larger tail surfaces and the 777style EFIS flightdeck with six flat panel LCDs which can present informationas on the 777 or as on the 737-300/400/500 series, the latter allowing acommon pilot type rating for the two 737 families. A HUD is optional. BBJstyle winglets are offered as an optional feature for the -800.

Until its launch on September5,1994 the 737-800 was known as the 737-400X Stretch. Compared with the -400 the -800 is 3.02m (9ft 9in) longer,taking typical two class seating from 146 to 162, while range is significantly

increased. The -800 has sold strongly since its launch, and early 2002 wasthe highest selling Next Generation model. First flight was on July 311997,first delivery (to Hapag Lloyd) was in April 1998.

The largest single order for the -800 series has come from the Irish budgetcarrier, Ryanair. After28 had already been ordered earlier, a firm order for100 aircraft was made in January 2002, with an option of another50, to bedelivered over the next 8 years. Ryanair will use the aircraft in a singleclass configuration, to seat 189 passengers

A variant of the 737-800 is the Boeing Business Jet 2 (BBJ2), which isdescribed separately.

HistoryThe hugely significant 747revolutionised airline transport. Farbigger than anything before it, the 747slashed operating costs per seat andthus cut the cost of long haulinternational airline travel.

Boeing conceived the 747 in the mid1960s following its failure to secure aUS Air Force contract for an ultra largestrategic transport (which resulted inthe Lockheed C-5 Galaxy), when itidentified a market for a high capacity'jumbo jet'. Boeing was able to drawupon design experience with the USAFtransport and launched the new airlineron July 251966. First flight occurredon February 91969, certification wasawarded on December 30 that year.

The basic 747-100 entered service with

Pan American in January 1970.Progressive development of the 747led to the 747-200B with higherweights, more powerful engines andlonger range. The -200B first flew inOctober1970 entering service withKLM, while nine higher weight 747-100Bs were built.

Developments include the 747-200Ffreighter, the SR (short range)optimised for high cycle short sectoroperations and the C (Combi).

The 747 holds a place in the public eyeunlike any other aircraft. The so called`Queen of the Skies' opened upinternational travel to millions. It is alsonotable for being the first widebodyairliner, the largest and heaviestairliner, and the first to use fuelefficient, high bypass turbofans.

HistoryBoeing's 747-300 model introducedthe distinctive stretched upper deckwhich can seat up to 69 economyclass passengers.

The 747-300 was the end result of a

number ofBoeing studies whichlooked at increasing the aircraft'sseating capacity. Ideas studiedincluded fuselage plugs fore and aft ofthe wing increasing seating to around600, or running the upper deck downthe entire length of the fuselage. In theend Boeing launched the moremodest 747SUD (Stretched UpperDeck) with greater upper deck seatingon June 121980.

The 747SUD designation was soonchanged to 747EUD (for ExtendedUpper Deck), and then 747-300. The

new model first flew on October51982 and was first delivered toSwissair on March 28 1983. Othercustomers included UTA, Saudia, SIA,Qantas and Cathay.

Compared to the -200, the -300'supper deck is stretched aft by 7.11m(23ft 4in), increasing economy classseating from 32 to a maximum of 69.The lengthened upper deckintroduced two new emergency exitdoors and allows an optionalflightcrew rest area immediately aft ofthe flightdeck to be fitted. Access isvia a conventional rather than spiralstaircase as on the earlier models.

Otherwise the 747-300 is essentiallylittle changed from the 747-200 andfeatures the same takeoff weight andengine options. 747-300 variantsinclude the 747-300M Combi and theshort range 747-300SR built for JapanAir Lines for domestic Japanese

HistoryThe 747-400 is the latest, longest rangingand best selling model of the 747 family.

Boeing launched the 747-400 in October1985 and the first development aircraftfirst flew on April 291988. US certification

(with PW-4000

s) was awarded in January1989.

The 747-400 externally resembles the -300, but it is a significantly improvedaircraft. Changes include a new, two crewdigital flightdeck with six large CRTdisplays, an increased span wing withwinglets (the -400 was the first airliner tointroduce winglets), new engines,recontoured wing/fuselage fairing, a newinterior, lower basic but increased maxtakeoff weights, and greater range.

Apart from the basic passenger747-400model, a number of variants have been

offered including the winglet-less 747-400Domestic optimised for Japanese shorthaul domestic sectors, the 747-400MCombi passenger/freight model, and the747-400F Freighter (which combines the747-200F's fuselage with the -400's wing).

The latest model is the 747-400ER, whichwas launched on November28,2000when Qantas placed an order for 6. The -400ER has the same size as the -400, but

has more range or payload capability. TheMTOW was increased by 15,870kg(35,000lb) to 412,770kg (910,000lb),giving a further range of 805km (435nm)or a 6800kg (15,000lb) greater payload.The -400ER also features a wholly newcabin interior with larger luggage bins,

and several flight deck improvements.The -400ER incorporates thestrengthened wing, body, and landinggear of the -400F, plus an auxiliary fueltank in the forward cargo hold, and anoptional second one. Operators who don'tneed these can remove them both,gaining additional cargo volume.

The first 747-400ER was rolled out inJune 2002, and flew for the first time onJuly 31,2002, and this was the 1308th747 to fly.

A cargo version, the 747-400ERF,

followed the standard -400ER, and waslaunched April 30,2001 on an order byleasing company ILFC for5. The first -400ERF is the 1315th 747 built. The -ERFhas the same MTOW as the -ER, and thiswill give an extra range of970km(525nm), or an extra payload of9980kg(22,000lb) at MTOW compared with thestandard -400F.

Shortly before delivery of the first -400ER,Boeing had received orders for15ER/ERFs from 5 customers.

Various growth 747 models have beenstudied. The 747-500X and -600X models

were dropped in January 1997. Boeing iscurrently proposing the 747-400XQLR(Quiet Longer Range) to 747-sizecustomers which will offer more range,more quiet, and more features.

increased thefuel fraction andthus range, italso meant thatseating capacitywas reduced.

The SP suffix in747SP standsfor SpecialPerformance,and points to theultra long rangeabilities of this747 variant that

preceded thelater747-400 by15 years. The747SP's range isbest illustratedby the spate oflong rangedistance recordsit set in the mid1970s. The mostprominent ofthose was thedelivery flight ofa South African

HistoryAfter a slow sales start, the medium

range single aisle 757 has become yetanother sales success story forBoeing.

Boeing considered a number of proposalsfor a successor to the 727 trijet during the1970s, with many of these designsfeaturing the nose and Ttail of the earlieret. It was not until later in that decadehowever that Boeing settled on a moreconventional design featuring the samecross section as the 727 (not to mentionthe 737,707 and 720) but with thefuselage considerably longer in length, anall new wing, nose and flightdeck and fuelefficient high bypass turbofan engines.

Boeing launched development of the 757in March 1979 following orders fromBritish Airways and Eastern. Developed intandem with the larger widebody 767 thetwo types share a number of systems andtechnologies, including a common earlygeneration EFIS flightdeck.

First flight was on February 191982 andthe 757 entered service in January thefollowing year. Subsequent versions to

Initial sales of the 757 were fairly slow,however orders picked up significantly inthe mid to late 1980s as traffic on routespreviously served by smaller727s and737s grew to require the 757's extracapacity.

Although design work on the original 757began in the late 1970s and its entry intoservice was in 1983, it wasn't until over adecade later in the mid 1990s that Boeingbegan to study a stretched development ofits popular narrowbody twin. This new 757stretch was covered by the 757-300X

designation until its launch at theFarnborough Airshow in England inSeptember1996.

The most obvious change over the 757-200 is the 300's 54.43m (178ft 7in) longfuselage, which is 7.11m (23ft 4in) longerthan the standard aircraft (and onlyfractionally shorter than the 767-300). Thisfuselage stretch allows a 20% increase inseating to 225 to 279 passengers,depending on the interior configuration.Lower hold freight capacity is alsoincreased by 40% over the 757-200 byvirtue of the longer fuselage.

Another feature of the 757-300 is its newinterior which is based on that developedfor the Next Generation 737 models.Features include a new sculptured ceiling,larger overhead bins, indirect overheadlighting and vacuum toilets.

The 757-300 shares the 200's cockpit,wing, tail and powerplant options, althoughthe 300 will feature strengthened structureand landing gear to cope with theincreased weights, new wheels, tyres andbrakes and a tailskid.

The 757-300 first flew on August 21998,

with certification in January 1999, andentry into service (with launch customerCondor- the charter arm of German flagcarrier Lufthansa) in March 1999. The -300's 27 month development programfrom final configuration to planned firstdelivery is the fastest for any Boeingairliner (the 777-300 took 31 months forexample).

The program was formallylaunched as the 767-400ERin January 1997 when DeltaAirlines ordered 21.

The most significant changewith the 767-300 is the 6.4m(21ft) fuselage stretch,which increases typicalthree class seating capacityfrom 218 to 245. Because ofthe increased fuselagelength the -400 features allnew, 46cm (18in) tallerlanding gear to restore

rotation angles foracceptable takeoff andlanding speeds anddistances which wouldotherwise have beenadversely affected by thefuselage stretch. Thewheels, tyres and brakesare common with the 777.

The basic 777-200 as launched in October1990 was offered in two versions, the basic

777-200 (initially A-Market) and theincreased weight longer range 777-200IGW(Increased Gross Weight, initially B-Market).The IGW has since been redesignated 777-200ER.

The 777-200 first flew on June 121994, withFAA and JAA certification awarded on April191995. The FAA awarded full 180 minutesETOPS clearance for PW4074 -200s onMay 30 that year. First customer deliverywas to United Airlines in May 1995. The first777-200IGW/ER was delivered to BritishAirways in February 1997.

The 777-100Xwas a proposed shortenedultra long range (16,000km/8635nm) model,dropped in favour of the 777-200LR(originally 777-200X) design study. Boeingclaims the 777-200LR will be the longestranging airliner, capable of flying 16,417km(8865nm) -18 hours flying time. It willachieve this with awesomely powerful489kN (110,000lb) thrust GE90-110B1turbofans, a significantly increased maxtakeoff weight and optional auxiliary fueltanks in the rear cargo hold. Other changesinclude 2m (6.5ft) raked wingtips, new mainlanding gear, structural strengthening and

optional overhead crew and flight attendantrest stations above the cabin. The 777-200LR was launched in 2000, but is nowdelayed until 2006.

HistoryBoeing's 777-300 is powered by the world'smost powerful turbofan engines.

The stretched 777-300 is designed as areplacement for early generation 747s(747-100s and 200s). Compared to the

older747s the stretched 777 hascomparable passenger capacity and range,but burns one third less fuel and features40% lower maintenance costs.

Compared with the baseline 777-200 the300 features a 10.13m (33ft 3in) stretch,comprising plugs fore and aft of the wings.The longer fuselage allows seating for up to550 passengers in a single class highdensity configuration. To cope with thestretch and the up to 13 tonne (28,600lb)increased max takeoff weight the 300features a strengthened undercarriage,airframe and inboard wing. Other changes

compared with the 777-200 include atailskid and ground manoeuvring camerasmounted on the horizontal tail andunderneath the forward fuselage.Otherwise changes have been kept to aminimum to maximise commonality.

Boeing publicly announced it wasdeveloping the 777-300 at the ParisAirshow in mid June 1995 where it revealedit had secured 31 firm orders from AllNippon, Cathay Pacific, Korean Airlines andThai Airways. Later that month Boeing'sboard authorised production of the newaircraft.

The 777-300 rolled out on September 81997, followed by first flight on October16that year. The type made history on May 41998 when it was awarded type certificationsimultaneously from the US FAA andEuropean JAA and was granted 180minETOPS approval. Service entry with CathayPacific was later in that month.

Like the 777-200, a 777-300ER long rangeversion has been developed. Changesmade to the 777-300ER are more powerfulGeneral Electric GE90-115B engines(currently the world's most powerful jetengine), raked wingtips, strengthened body,wings, empennage, nose gear, enginestruts and nacelles, new main landing gear,and provision for extra fuel tanks. Therange, carrying 365 passengers, isincreased up to 13,427km (7,250nm).

Roll-out of the first 777-300ER was madeon November14 2002, followed by the firstflight on February 24 2003. First delivery, toAir France, is scheduled for March 2004.

TypeFour-Engined Long Range Heavy Bomber

HistoryThe Fortress was originally designed tomeet a bomber specification issued by theU.S. Army Air Corps in 1934. Theprototype,Boeing Model 299, first flew onJuly 28,1935 and the first Y1B-17 of aproduction order of thirteen was deliveredto the Air Corps in March,1937. InJanuary,1939 an experimental Y1B-17Afitted with turbo-supercharged engines wasdelivered to the Army Air Corps. Followingsuccessful trials with this aircraft an orderfor 39 was placed for this model under thedesignation B-17B.

The B-17G was introduced onto theFortress production line in July of1943,and was destined to be produced in largernumbers than any other Fortress variant.The most readily-noticeable innovationintroduced by the B-17G was the power-operated Bendix turret mounted in a chin-type installation underneath the nose. Thisturret was equipped with two 0.50-inch

machine guns. This installation had firstbeen tested in combat by the YB-40 andwas found to be the only viable innovationintroduced by the unsuccessful escortFortress. Another innovation introduced bythe G was having the waist guns beingpermanently enclosed behind windowsinstead of being mounted behindremovable hatches. This made the rearfuselage somewhat less drafty. The cheeknose guns introduced on the late B-17F

were retained, but were staggered so thatthe left gun was in the forward side windowand the right gun was in the middle sidewindow, which reversed the positions usedon the late Fs. The cheek gun mountsbulged somewhat outward into theairstream, which helped to improve the

forward view from the cheek gun positions.The forward chin installation and theassociated cheek guns were first testedout on B-17F-115-BO 42-30631. Originally,the Bendix turret was to be introduced onthe Boeing production line with F-135, butthe changes were sufficient to justify a newseries letter, and the F-135s became G-1.

The B-17G now had the defensivefirepower of no less than thirteen 0.50-inchmachine guns: two chin guns, two cheekguns, two guns in the dorsal turret, twoguns in the ventral turret, two guns in thewaist, two guns in the tail and one gun in

the roof of the radio operator's position. B-17Gs were built by all three members ofthe "B.V.D." production pool, with theBoeing lots ranging from production blocksG-1 to G-110, the Douglas blocks rangingfrom -5 to -95, and the Lockheed-Vegablocks ranging from -1 to -110.

The B-17G entered service with the Eighthand Fifteenth Air Forces in late 1943.Camouflage paint was deleted fromproduction B-17Gs starting in January of1944. B-17Gs were delivered in naturalmetal finish starting in (but not at thebeginning) of production blocks G-35-BO

(Boeing), G-20-VE (Lockheed-Vega), andG-35-DL (Douglas-Long Beach). The so-called "Cheyenne" tail gun mountingmodifications were incorporated in the B-17G-80-BO,-45-DL,-35-VE andsubsequent batches. These tail gunmountings also had a reflector gunsightinstead of the previous ring and bead. Withthis installation, these B-17Gs were fiveinches shorter than the earlier versions.On later production versions, it was foundnecessary to stagger the waist gunpositions so that the two gunners wouldnot get in each other's way. On the last

production batches (B-17G-105 and -110-BO,B-17G-75 to -85-DL, and B-17G-85 to-110-VE), the radio compartment gun wasnot installed. The ammunition capacity ofthe waist guns was increased to 600 rpg.When production terminated in 1945, atotal of 4035B-17Gs had been built byBoeing,2395 by Douglas and 2250 byLockheed-Vega. The last Boeing-built B-17G was delivered on April 13,1945. B-

TypeFreighter

HistoryBoeing's Stratofreighter formedthe backbone of the US AirForce's Military Airlift TransportService (MATS) during the early1950s, and more than 800 werebuilt for use as freighters and air-to-air refuellers.

The Model 367 Stratofreighter isbased on the Boeing B-29Superfortress, the Allies' most

technologically advanced bomberto see service in World War2, andan aircraft famous (or infamous)for dropping the only atomicbombs used operationally inwarfare on Japan in the closingstages of that conflict. The B-29flew for the first time in September1942 by which time Boeing hadalready studied a t ransportversion, utilising the B-29's wing,engines, tail and lower fuselage,combined with a new upperfuselage section. The new double

lobe fuselage shape was verydistinctive, and also formed thebasis for future Boeing jet airlinerfuselage cross sections.

The US Army Air Force wasimpressed with Boeing's proposalsand ordered three prototypes bebuilt, the first of which
