For other aircraft called Comet, see, Comet 4B 3-view schematic (front, side, and dorsal views), Comet 1 3-view in silhouette (note differences in Comet 4 insert, reproduced in same scale), During the same era, both Lockheed with their, The "Type IV" Specifications issued on 3 February 1943 provided for a "high-speed mail-carrying airliner, gas-turbine powered. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes.) Hall: "In the light of known properties of the aluminium alloy D.T.D. The De Havilland Comet was used on BOAC's transatlantic crossing Credit: Getty I t all started with a newspaper. "[125] "DeHavilland went to oval windows on the subsequent Marks because it was easier to Redux them in,(use adhesive) - nothing to do with the stress concentration and it's purely to remove rivets." [102] Comet flights resumed on 23 March 1954. Jones, Barry. BOADICEA COMPUTER SYS at the best online prices at eBay! BOAC DE HAVILLAND COMET 4 RADIO MAINTENANCE SCHEDULE - ORIGINAL AND RARE 384272193709 [82] American carriers Capital Airlines, National Airlines, and Pan Am placed orders for the planned Comet 3, an even-larger, longer-range version for transatlantic operations. BOAC took delivery of 10 Comets and the first passenger service opened to Johannesburg on 2 May 1952.

[72], Prince Philip returned from the Helsinki Olympic Games with G-ALYS on 4 August 1952. [82][186] A hangar fire damaged a No. VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. This is at your risk. He stated "Every time we pulled 2 1/2-3G to go around the corner, Chris found that the floor on which he was standing, bulging up and there was a loud bang at that speed from the nose of the aircraft where the skin 'panted' (flexed), so when we heard this bang we knew without checking the airspeed indicator, that we were doing 340 knots. [173] A Comet 4C (SA-R-7) was ordered by Saudi Arabian Airlines with an eventual disposition to the Saudi Royal Flight for the exclusive use of King Saud bin Abdul Aziz. The Comet was also adapted for a variety of military roles such as VIP, medical and passenger transport, as well as surveillance; the last Comet 4, used as a research platform, made its final flight in 1997. [173] This variant became the Hawker Siddeley Nimrod and production aircraft were built at the Hawker Siddeley factory at Woodford Aerodrome. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. Chief designer Bishop chose the Comet's embedded-engine configuration because it avoided the drag of podded engines and allowed for a smaller fin and rudder since the hazards of asymmetric thrust were reduced. [4], The committee accepted the proposal, calling it the "Type IV" (of five designs),[N 3] and in 1945 awarded a development and production contract to de Havilland under the designation Type 106. [90], The Comet's second fatal accident occurred on 2 May 1953, when BOAC Flight 783, a Comet 1, registered G-ALYV, crashed in a severe thundersquall six minutes after taking off from Calcutta-Dum Dum (now Netaji Subhash Chandra Bose International Airport), India,[91] killing all 43 on board. [N 20], The issue of the lightness of Comet 1 construction (in order to not tax the relatively low thrust DeHavilland Ghost engines), had been noted by DeHavilland test pilot John Wilson, while flying the prototype during a Farnborough flypast in 1949. The second prototype was registered G-ALZK in July 1950 and it was used by the BOAC Comet Unit at Hurn from April 1951 to carry out 500 flying hours of crew training and route-proving. BOAC's Comet 4s were leased out to Air Ceylon, Air India, AREA Ecuador, Central African Airways[179] and Qantas Empire Airways;[81][180] after 1965 they were sold to AREA Ecuador, Dan-Air, Mexicana, Malaysian Airways, and the Ministry of Defence. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes). For the 1930s racing aircraft, see, "Comet (aircraft)" redirects here. LONDON, Jan. 2 (ReutersSir Giles Guthrie, new c hairman of the publicIy owned British Overseas Airways Corporation has ordered a review of the . Witnesses observed the wingless Comet on fire plunging into the village of Jagalgori,[92] leading investigators to suspect structural failure. [170] Assigned in 1961 to the Blind Landing Experimental Unit (BLEU) at RAE Bedford, the final testbed role played by GANLO was in automatic landing system experiments. The American jets were larger, faster, longer-ranged and more cost-effective than the Comet. [116] Based on these findings, Comet 1 structural failures could be expected at anywhere from 1,000 to 9,000 cycles. BOAC would go on to dominate the London-New York route in the 1960s and early 1970s with Pan Am, but when it came to airliners the Americans were the long-term winners. [62], The Comet 2 had a slightly larger wing, higher fuel capacity and more-powerful Rolls-Royce Avon engines, which all improved the aircraft's range and performance;[161] its fuselage was 3ft 1in (0.94m) longer than the Comet 1's. IN VENDITA! In 1949 BOAC introduced the first of what was termed an 'all-land' service using Canadair Argonauts on their London to Hong Kong/Tokyo route, via Rome, Cairo, Basra, Karachi, Calcutta, Rangoon and Bangkok. On 10 January 1954, a de Havilland Comet passenger jet operating the flight suffered an explosive decompression at altitude and crashed, killing all 35 people on board. [112] This time, the entire fuselage was tested in a dedicated water tank that was built specifically at Farnborough to accommodate its full length. [N 16] Professor Natesan Srinivasan joined the inquiry as the main technical expert. All 43 on board were killed. G-ALYP a/f 6003. Be sure to check my channel for the best in VINTAGE & RARE airliner videos! ", Duncan Sandys, Minister of Supply, 1952. Simons, Graham M. "Comet! Oakey, Michael, ed. The De Havilland Aircraft Company DH106 Comet was the World's first pressurised commercial jet airliner and it was the source of enormous national pride. Besides the 707 and DC-8, the introduction of the Vickers VC10 allowed competing aircraft to assume the high-speed, long-range passenger service role pioneered by the Comet. de Havilland Comet 1 jet airliner . [166], The Comet 3, which flew for the first time on 19 July 1954, was a Comet 2 lengthened by 15ft 5in (4.70m) and powered by Avon M502 engines developing 10,000lbf (44kN). Most commonly quoted are the 'square' passenger windows. On 4 October . "Comet Service To South America Planned" (News). In May 1952 BOAC became the first airline in the world to fly passenger jets with the de Havilland Comet which initially flew via Nairobi to Johannesburg and via the Far East to Tokyo. BOAC South Pacific Route Menu, New York - 204250723949 [194] A Comet 4B (G-APYD) is stored in a facility at the Science Museum at Wroughton in Wiltshire, England. Cunningham: "[the Comet] flew extremely smoothly and responded to the controls in the best way de Havilland aircraft usually did.". [N 15] In summer 1953, eight BOAC Comets left London each week: three to Johannesburg, two to Tokyo, two to Singapore and one to Colombo. BOAC's requested capacity increase was known as Specification 22/46. The most extensive modification resulted in a specialised maritime patrol derivative, the Hawker Siddeley Nimrod, which remained in service with the Royal Air Force until 2011, over 60 years after the Comet's first flight. [75], In 1953, the Comet appeared to have achieved success for de Havilland. Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. Principal investigator Hall accepted the RAE's conclusion of design and construction flaws as the likely explanation for G-ALYU's structural failure after 3,060 pressurisation cycles. ", Prime Minister Winston Churchill, 1954. Examination of the cockpit controls suggested that the pilot may have inadvertently over-stressed the aircraft when pulling out of a steep dive by over-manipulation of the fully powered flight controls. A number of other pressurised airliners of the period including the Boeing 377 Stratocruiser, Douglas DC-7, and DC-8 had larger more 'square' windows than the Comet 1 and experienced no such failures. [1], The Comet is widely regarded as both an adventurous step forward and a supreme tragedy; the aircraft's legacy includes advances in aircraft design and in accident investigations.

On 3 March 1953, a new Canadian Pacific Airlines Comet 1A, registered CF-CUN and named Empress of Hawaii, failed to become airborne while attempting a night takeoff from Karachi, Pakistan, on a delivery flight to Australia. (Cohen Inquiry accident report Fig 7). [49], The Comet's thin metal skin was composed of advanced new alloys[N 13] and was both riveted and chemically bonded, which saved weight and reduced the risk of fatigue cracks spreading from the rivets. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. [82][187], Pilot error resulting in controlled flight into terrain was blamed for five fatal Comet 4 accidents: an Aerolneas Argentinas crash near Asuncin, Paraguay, on 27 August 1959, Aerolneas Argentinas Flight 322 at Campinas near So Paulo, Brazil, on 23 November 1961, United Arab Airlines Flight 869 in Thailand's Khao Yai mountains on 19 July 1962, a Saudi Arabian Government crash in the Italian Alps on 20 March 1963, and United Arab Airlines Flight 844 in Tripoli, Libya, on 2 January 1971. [97] Aviation author Bill Withuhn concluded that the Comet had pushed "'the state-of-the-art' beyond its limits. BOAC chmn Guthrie orders rev of co's routes. To achieve optimum efficiency with the new powerplants, the air intakes were enlarged to increase mass air flow. On the 10 th December R. Clear commanded test flights from Hatfield. The Ministry of Supply was interested in the most radical of the proposed designs, and ordered two experimental tailless DH 108s[N 5] to serve as proof of concept aircraft for testing swept-wing configurations in both low-speed and high-speed flight. [4] One of its recommendations was for the development and production of a pressurised, transatlantic mailplane that could carry 1 long ton (2,200lb; 1,000kg) of payload at a cruising speed of 400mph (640km/h) non-stop. In later years we realised that these were the indications of how flimsy the structure really was. [151][152], Aeronautical-engineering firms were quick to respond to the Comet's commercial advantages and technical flaws alike; other aircraft manufacturers learned from, and profited by, the hard-earned lessons embodied by de Havilland's Comet. [81][82] When the redesigned Comet 4 entered service, it was flown by customers BOAC, Aerolneas Argentinas, and East African Airways,[178] while the Comet 4B variant was operated by customers BEA and Olympic Airways [178] and the Comet 4C model was flown by customers Kuwait Airways, Mexicana, Middle East Airlines, Misrair Airlines and Sudan Airways. [93] The Comet 1 and 1A had been criticised for a lack of "feel" in their controls,[95] and investigators suggested that this might have contributed to the pilot's alleged over-stressing of the aircraft;[96] Comet chief test pilot John Cunningham contended that the jetliner flew smoothly and was highly responsive in a manner consistent with other de Havilland aircraft. [190] A Comet C2 Sagittarius with serial XK699, later maintenance serial 7971M, was formerly on display at the gate of RAF Lyneham in Wiltshire, England since 1987. [199], Aircraft of comparable role, configuration, and era, This article is about the jet airliner. [47] In 1969, when the Comet 4's design was modified by Hawker Siddeley to become the basis for the Nimrod, the cockpit layout was completely redesigned and bore little resemblance to its predecessors except for the control yoke. BOAC installed 36 reclining "slumberseats" with 45in (1,100mm) centres on its first Comets, allowing for greater leg room in front and behind;[30] Air France had 11 rows of seats with four seats to a row installed on its Comets. ", "De Havilland Comet 4C G-BDIX Interior View Scottish Museum of Flight. [165] Although these aircraft performed well on test flights on the South Atlantic, their range was still not suitable for the North Atlantic. 106 Comet.". . [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952. [51], When several of the fuselage alloys were discovered to be vulnerable to weakening via metal fatigue, a detailed routine inspection process was introduced. Super VC10 G-ASGE seen in the BOAC/Cunard colours during the period that the airline and shipping line co-operated on UK-USA routes. The move was cancelled due to the level of corrosion and the majority of the airframe was scrapped in 2013, the cockpit section going to the Boscombe Down Aviation Collection at Old Sarum Airfield[193], Six complete Comet 4s are housed in museum collections. Free shipping. The Imperial War Museum Duxford has a Comet 4 (G-APDB), originally in Dan-Air colours as part of its Flight Line Display, and later in BOAC livery at its AirSpace building. $39.99. [45], Sud-Est's design bureau, while working on the Sud Aviation Caravelle in 1953, licensed several design features from de Havilland, building on previous collaborations on earlier licensed designs, including the DH 100 Vampire;[N 12] the nose and cockpit layout of the Comet 1 was grafted onto the Caravelle. Although G-APAS never flew in BOAC markings, this colour scheme is representative of the first ever fleet of passenger jet aircraft. Peggy Thorne, pictured left, in her BOAC uniform ahead of the first transatlantic jet engine flight in 1958 and the crew on board the BOAC Comet. 546 or 746 of which the skin was made and in accordance with the advice I received from my Assessors, I accept the conclusion of RAE that this is a sufficient explanation of the failure of the cabin skin of Yoke Uncle by fatigue after a small number, namely, 3,060 cycles of pressurisation.". The inaugural flight was filmed, and a video and transcript is below: Now in great ships of the sky, British captains and their crews wing their way half around the world to Australia in 33 hours, almost 13,000 miles. [38], Several of the Comet's avionics systems were new to civil aviation. Hill, Malcolm L. "de Havilland's Comet: Pushing the Boundaries.". $75.00. On 22 nd September this BOAC Comet was flown from Stansted to London Airport. All airline customers for the Comet 3 subsequently cancelled their orders and switched to the Comet 4,[63] which was based on the Comet 3 but with improved fuel capacity. [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. The court acted under the provisions of Rule 75 of the Indian Aircraft Rules 1937. Mk.1. The only complete remaining Comet 1, a Comet 1XB with the registration G-APAS, the very last Comet 1 built, is displayed at the RAF Museum Cosford. [118] Once the crack initiated the skin failed from the point of the ADF cut out and propagated downwards and rearwards along a stringer resulting in an explosive decompression. ", "De Havilland Comet 4B airliner, serial no 6438, 1960. Posts: 86 [141] The last Comet 4 variant, the Comet 4C, first flew on 31 October 1959 and entered service with Mexicana in 1960. For VIP transport, the seating and accommodations were altered and provisions for carrying medical equipment including iron lungs were incorporated. [74], In their first year, Comets carried 30,000 passengers. Range: 3,225 miles (5,190 km) Passengers: 60 to 81 On display at the Museum: The Museum's exhibit is a Comet 4 analogue flight simulator for crew training was built for BOAC by Redifon Flight Simulation at Crawley. Investigators did not consider metal fatigue as a contributory cause. [42] Power was syphoned from all four engines for the hydraulics, cabin air conditioning, and the de-icing system; these systems had operational redundancy in that they could keep working even if only a single engine was active. The inquiry concluded that the aircraft had encountered extreme negative G forces during takeoff; severe turbulence generated by adverse weather was determined to have induced down-loading, leading to the loss of the wings. Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. The five-stop flight from London to Johannesburg was scheduled for 21 hr 20 min. [43] A pressurised refuelling system, developed by Flight Refuelling Ltd, allowed the Comet's fuel tanks to be refuelled at a far greater rate than by other methods. Modifications to the interiors allowed the Comet 2s to be used in several roles. Sections of pressurised fuselage were subjected to high-altitude flight conditions via a large decompression chamber on-site [N 10] and tested to failure. [110][128], Following the Comet enquiry, aircraft were designed to "Fail safe" or "Safe Life" standards,[129] though several subsequent catastrophic fatigue failures, such as Aloha Airlines Flight 243 of April 28, 1988 have occurred. [10], A design team was formed in 1946 under the leadership of chief designer Ronald Bishop, who had been responsible for the Mosquito fighter-bomber.

[63] Upgraded Avon engines were introduced on the Comet 3,[63] and the Avon-powered Comet 4 was highly praised for its takeoff performance from high-altitude locations such as Mexico City where it was operated by Mexicana de Aviacion, a major scheduled passenger air carrier. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. [44], The cockpit was significantly altered for the Comet 4's introduction, on which an improved layout focusing on the onboard navigational suite was introduced. [164] The first production aircraft (G-AMXA) flew on 27 August 1953. [169] As a flying testbed, it was later modified with Avon RA29 engines fitted, as well as replacing the original long-span wings with reduced span wings as the Comet 3B and demonstrated in British European Airways (BEA) livery at the Farnborough Airshow in September 1958. canuck DC-8. On whether we grasp this opportunity and so establish firmly an industry of the utmost strategic and economic importance, our future as a great nation may depend. All but four Comet 2s were allocated to the RAF, deliveries beginning in 1955. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. [25] Australian airline Qantas also sent its own technical experts to observe the performance of the prototypes, seeking to quell internal uncertainty about its prospective Comet purchase. "The de Havilland Comet Srs. The operation was short-lived and was dissolved in 1966. As well as thorough visual inspections of the outer skin, mandatory structural sampling was routinely conducted by both civil and military Comet operators. Dr P. B. Walker, Head of the Structures Department at the RAE, said he was not surprised by this, noting that the difference was about three to one, and previous experience with metal fatigue suggested a total range of nine to one between experiment and outcome in the field could result in failure. [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. - May 06, 1959 Operated the inaugural London (Heathrow) - Sydney (Kingsford Smith) service - November 01, 1959 Route: London - Beirut - Karachi - Singapore - Sydney This aircraft was one of six Comet 4 aircraft wet-leased by Qantas Empire Airways from 1959 to 1963 [97][N 17], Just over a year later, Rome's Ciampino airport, the site of the first Comet hull loss, was the origin of a more-disastrous Comet flight. Here we have a superbly illustrated trade card, depicting a B.O.A.C. Although sales never fully recovered, the improved Comet2 and the prototype Comet3 culminated in the redesigned Comet4 series which debuted in 1958 and remained in commercial service until 1981. ", "On This Day: Comet inaugurates the jet age.". ST-AAX Comet 4C. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. [N 22][163] A total of 12 of the 44-seat Comet 2s were ordered by BOAC for the South Atlantic route. BEA's Super One-Eleven aircraft enter scheduled service on German internal routes. [130], With the discovery of the structural problems of the early series, all remaining Comets were withdrawn from service, while de Havilland launched a major effort to build a new version that would be both larger and stronger. This artificial feel was the first of its kind to be introduced in any aircraft. In April 1960, 13 Comets, 19 Britannias and 6 DC-7Cs. [37] The navigator occupied a dedicated station, with a table across from the flight engineer. BOAC flight crew revelled in standing a pen on end and pointing that out to passengers; invariably, the pen remained upright throughout the entire flight. ), BOAC, and de Havilland. Also in that year the Comet route to New York was extended to Nassau and Montego Bay. They are rectangular not square, have rounded corners and are within 5% of the radius of the Boeing 737 windows and virtually identical to modern airliners. [49] At its introduction, Comet airframes would be subjected to an intense, high-speed operating schedule which included simultaneous extreme heat from desert airfields and frosty cold from the kerosene-filled fuel tanks, still cold from cruising at high altitude. 192 Squadron RAF Comet 2R beyond repair on 13 September 1957, and three Middle East Airlines Comet 4Cs were destroyed by Israeli troops at Beirut, Lebanon, on 28 December 1968. BOAC Comet 4 British Airways Source: Duxford Aviation Society Soon after, Boeing launched its first long-haul narrowbody jet, the four-engine Boeing 707, using the lessons learned from the. On 10 January 1954, British Overseas Airways Corporation Flight 781 a de Havilland DH.106 Comet 1 registered G-ALYP, took off from Ciampino Airport in Rome, Italy, en route to Heathrow Airport in London, England, on the final leg of its flight from Singapore. This was because in 1945 no turbojet engine manufacturer in the world was drawing-up a design specification for an engine with the thrust and specific fuel consumption that could power an aircraft at the proposed cruising altitude (40,000ft (12,000m)), speed, and transatlantic range as was called for by the Type 106. One such feature was irreversible, powered flight controls, which increased the pilot's ease of control and the safety of the aircraft by preventing aerodynamic forces from changing the directed positions and placement of the aircraft's control surfaces. The airline eventually became British Airways through a merger and continues flying the Boeing 747 between London and several U.S.. 1 November: The inaugural flight of a BOAC De Havilland Comet 4 aircraft on the London to Sydney route took place. Delivered to British Overseas Airways Corporation (B.O.A.C.) Courtesy British Airways. The Comet 4 was ordered by two other airlines: Aerolneas Argentinas took delivery of six Comet 4s from 1959 to 1960, using them between Buenos Aires and Santiago, New York and . BCPA had actually ordered three Comet 2s from de Havilland, although the agreement had never been fully finalised. "The Dawn of the Jet Age in Austerity Britain: David Lean's The Sound Barrier". First production Comet for BOAC. [149], According to de Havilland's chief test pilot John Cunningham, who had flown the prototype's first flight, representatives from American manufacturers such as Boeing and Douglas privately disclosed that if de Havilland had not experienced the Comet's pressurisation problems first, it would have happened to them. In September 1972 the airlines of BOAC and BEA began a merger, eventually forming British Airways on 31 March 1974. Winchester, Jim, ed. [195] Comet 4Cs are exhibited at the Flugausstellung Peter Junior at Hermeskeil, Germany (G-BDIW),[196] the Museum of Flight Restoration Center near Everett, Washington (N888WA),[181] and the National Museum of Flight near Edinburgh, Scotland (G-BDIX). Unlike drill riveting, the imperfect nature of the hole created by punch-riveting could cause fatigue cracks to start developing around the rivet. The Comet gave BOAC four years lead in modern jet airliners over the rest of the world. [48], Diverse geographic destinations and cabin pressurisation alike on the Comet demanded the use of a high proportion of alloys, plastics, and other materials new to civil aviation across the aircraft to meet certification requirements. BOAC went on to fly the 707 on its own trans-Atlantic flights. BOAC, British Airways' predecessor, operated the first transatlantic jet engine flight on 4 October, 1958, beating arch-rival Pan Am to become the first to do so. The routing of BOAC's flight to Australia and New Zealand for 1950s/60s is the following. Four Ghost 50 Mk 1 engines were fitted (later replaced by more powerful Ghost DGT3 series engines). ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. G-ALYP Author. De Havilland nonetheless began a refit programme to strengthen the fuselage and wing structure, employing thicker-gauge skin and replacing the rectangular windows and panels with rounded versions, although this was not related to the erroneous 'square' window claim, as can be seen by the fact that the fuselage escape hatch cut-outs (the source of the failure in test aircraft G-ALYU) retained their rectangular shape. [57] The Comet's buried-engine configuration increased its structural weight and complexity. [83][84] Qantas was interested in the Comet 1 but concluded that a version with more range and better takeoff performance was needed for the London to Canberra route. Both of these aeroplanes would continue to operate side by side until the formation of British Airways PLC in 1974. In November 1965, BOAC retired its Comet 4s from revenue service; other operators continued commercial passenger flights with the Comet until 1981. [27], The Comet was an all-metal low-wing cantilever monoplane powered by four jet engines; it had a four-place cockpit occupied by two pilots, a flight engineer, and a navigator. The other Comet 3 airframe was not completed to production standard and was used primarily for ground-based structural and technology testing during development of the similarly sized Comet 4. 46 hours 45 minutes. to increase mass air flow abandoned at Hatfield April and at.
