As well as thorough visual inspections of the outer skin, mandatory structural sampling was routinely conducted by both civil and military Comet operators. [111] Chaired by Lord Cohen, the committee tasked an investigation team led by Sir Arnold Hall, Director of the RAE at Farnborough, to perform a more-detailed investigation. BEA's Super One-Eleven aircraft enter scheduled service on German internal routes. Worldwide International 134457089011 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. [75], In 1953, the Comet appeared to have achieved success for de Havilland. Singapore arrival mark on back. . 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. BOAC flew two de Havilland Comet 4 aircraft between London and New York International Airport, Idlewild. [28] The clean, low-drag design of the aircraft featured many design elements that were fairly uncommon at the time, including a swept-wing leading edge, integral wing fuel tanks, and four-wheel bogie main undercarriage units designed by de Havilland. [72], Prince Philip returned from the Helsinki Olympic Games with G-ALYS on 4 August 1952. In later years we realised that these were the indications of how flimsy the structure really was. [20] One window frame survived 100psi (690kPa),[21] about 1,250 percent over the maximum pressure it was expected to encounter in service. ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. Courtesy British Airways. [55] The engines were outfitted with baffles to reduce noise emissions, and extensive soundproofing was also implemented to improve passenger conditions. A year later, the second prototype G-5-2 made its maiden flight. Although the 707 was winning most of the major airline orders, BOAC, flying Comet 4s, still managed to achieve the first commercial transatlantic crossing in a jet airliner - twice. On 11 March 1943, the Cabinet of the United Kingdom formed the Brabazon Committee, which was tasked with determining the UK's airliner needs after the conclusion of the Second World War. Photo L. Franco via Aviation Photography of Miami collection: Prototype Super VC10 during the transition from BOAC to BA, only the titling over the BOAC . ", "XS235 - De Havilland DH-106 Comet 4C - United Kingdom - Royal Air Force (RAF) - David Oates", "Milestones in Aircraft Structural Integrity", "Aircraft Accident Report AAR8903: Aloha Airlines, Flight 243, Boeing 737-200, N73711", "De Havilland DH.106 Comet 4C, OD-ADT, MEA Middle East Airlines. [175][N 24], The last two Comet 4C aircraft produced were modified as prototypes (XV148 & XV147) to meet a British requirement for a maritime patrol aircraft for the Royal Air Force; initially named "Maritime Comet", the design was designated Type HS 801. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. 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. ), BOAC, and de Havilland. The Comet, with its. Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time; the other was due to overstressing of the airframe during flight through severe weather. "[127], The Cohen inquiry closed on 24 November 1954, having "found that the basic design of the Comet was sound",[111] and made no observations or recommendations regarding the shape of the windows. All but four Comet 2s were allocated to the RAF, deliveries beginning in 1955. [20], The first prototype DH.106 Comet (carrying Class B markings G-5-1) was completed in 1949 and was initially used to conduct ground tests and brief early flights. [24], The prototype was registered G-ALVG just before it was publicly displayed at the 1949 Farnborough Airshow before the start of flight trials. [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. "A BOAC de Havilland Comet jet airliner, en route to Johannesburg from London, breaks its journey at Entebbe Airport, Uganda, 1952." (Ministry of Information official photographer) The de Havilland Comet was the first commercial jet airliner and its introduction had revolutionized the industry. Comets quit flying the North Atlantic in October 1960 (but reportedly made a few flights in summer 1964). [63] All production Comet 2s were also modified with thicker gauge skin to better distribute loads and alleviate the fatigue problems (most of these served with the RAF as the Comet C2); a programme to produce a Comet 2 with more powerful Avons was delayed. [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. [38], Several of the Comet's avionics systems were new to civil aviation. "[174], The Comet 5 was proposed as an improvement over previous models, including a wider fuselage with five-abreast seating, a wing with greater sweep and podded Rolls-Royce Conway engines. The first Comet 4B flew on 27 June 1959 and BEA began Tel Aviv to London-Heathrow services on 1 April 1960. [33] Provisions for emergency situations included several life rafts stored in the wings near the engines, and individual life vests were stowed under each seat. In command was Capt Tom Stoney, manager of BOAC's Comet Flight. In April 1960, 13 Comets, 19 Britannias and 6 DC-7Cs. BOAC DE HAVILLAND COMET 4 RADIO MAINTENANCE SCHEDULE - ORIGINAL AND RARE 384272193709 [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. BOAC Comet 4 Captains Folder Africa routes original 1960s document Comet 4[edit] 304755204133. [22][23] At the controls was de Havilland chief test pilot John "Cats Eyes" Cunningham, a famous night-fighter pilot of the Second World War, along with co-pilot Harold "Tubby" Waters, engineers John Wilson (electrics) and Frank Reynolds (hydraulics), and flight test observer Tony Fairbrother. The redesigned aircraft was named the DH.106 Comet in December 1947. This is at your risk. Birtles, P.J. [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). 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. Following closely the design features of the two prototypes, the only noticeable change was the adoption of four-wheel bogie main undercarriage units, replacing the single main wheels. G-APDM Comet 4. [5][11] During flight tests, the DH 108 gained a reputation for being accident-prone and unstable, leading de Havilland and BOAC to gravitate to conventional configurations and, necessarily, designs with less technical risk. ", "De Havilland DH.106 Comet 4, G-APDJ, Air Ceylon. The Comet Story. The sole surviving Comet fuselage with the original square-shaped windows, part of a Comet 1A registered F-BGNX, has undergone restoration and is on display at the de Havilland Aircraft Museum in Hertfordshire, England. "The de Havilland Comet Srs. The Abell Committee focused on six potential aerodynamic and mechanical causes: control flutter (which had led to the loss of DH 108 prototypes), structural failure due to high loads or metal fatigue of the wing structure, failure of the powered flight controls, failure of the window panels leading to explosive decompression, or fire and other engine problems. [103], "The cost of solving the Comet mystery must be reckoned neither in money nor in manpower. Atkinson, R. J., W. J. Winkworth and G. M. Norris. Cunningham: "[the Comet] flew extremely smoothly and responded to the controls in the best way de Havilland aircraft usually did.". BOAC ordered 19 Comet 4s in March 1955, and American operator Capital Airlines ordered 14 Comets in July 1956. The five-stop flight from London to Johannesburg was scheduled for 21 hr 20 min. ", "Commercial Aircraft 1953: De Havilland Comet. 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. 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. [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. [124] In fact, the Comet 1's window general shape resembles a slightly larger Boeing 737 window mounted horizontally. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. [69] While BOAC gained publicity as the first to provide transatlantic jet service, by the end of the month rival Pan American World Airways was flying the Boeing 707 on the New York-Paris route, with a fuel stop at Gander in both directions,[136] and in 1960 began flying Douglas DC-8's on its transatlantic routes as well. The Comet 1 was powered by four 2,018 kg thrust de Havilland Ghost turbojets buried in the wing roots. 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. [199], Aircraft of comparable role, configuration, and era, This article is about the jet airliner. 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. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. The wing was drastically redesigned from a 40 sweep. G-ALYP Author. Although the fuselage failed after a number of cycles that represented three times the life of G-ALYP at the time of the accident, it was still much earlier than expected. [73] Flights on the Comet were about 50 percent faster compared to advanced piston-engined aircraft such as the Douglas DC-6 (490mph (790km/h)) The type and design were to be so advanced that de Havilland had to undertake the design and development of both the airframe and the engines. The Comet was withdrawn from service and extensively tested. Posts: 86 - 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 ", "De Havilland Comet 4C G-BDIX Interior View Scottish Museum of Flight. XK695 Comet 2R. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes). [189] Though painted in BOAC colours, it never flew for the airline, having been first delivered to Air France and then to the Ministry of Supply after conversion to 1XB standard;[189] this aircraft also served with the RAF as XM823. Armour had to be placed around the engine cells to contain debris from any serious engine failures; also, placing the engines inside the wing required a more complicated wing structure. 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.

[82][143], In 1959 BOAC began shifting its Comets from transatlantic routes[N 21] and released the Comet to associate companies, making the Comet 4's ascendancy as a premier airliner brief. On the flight, he was accompanied by Chris Beaumont, Chief Test Pilot of the DeHavilland Engine Company (that made the Comet 1's Ghost engines) who stood in the entrance to the cockpit behind the Flight Engineer. 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. [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. 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. In August 1953 BOAC scheduled the nine-stop London to Tokyo flights by Comet for 36 hours, compared to 86 hours and 35 minutes on its Argonaut piston airliner. As a result, the Comet was extensively redesigned, with oval windows, structural reinforcements and other changes. Though these lessons could be implemented on the drawing board for future aircraft, corrections could only be retroactively applied to the Comet. [74], In their first year, Comets carried 30,000 passengers. Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. The COMET 4 remained in BOAC trans-Atlantic service though as new north American destinations . Within a year of entering airline service, problems started to emerge, three Comets being lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. All early Comets were withdrawn from service for accident inquiries, during which orders from British Commonwealth Pacific Airlines, Japan Air Lines, Linea Aeropostal Venezolana, National Airlines, Pan American World Airways and Panair do Brasil were cancelled. "Report of the court investigation on the accident to COMET G-ALYV", "B.O.A.C. ARD ARD2012 BOAC De Havilland DH.106 Comet 4 G-APDT Diecast 1/200 Model Airplane. Las mejores ofertas para BOAC DE HAVILLAND COMET 4 LAVATORY ORIGINAL VINTAGE B.O.A.C. [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. [31][60] These were tested on 30 flights, but the Ghosts alone were considered powerful enough and some airlines concluded that rocket motors were impractical. [142] The Comet 4C had the Comet 4B's longer fuselage and the longer wings and extra fuel tanks of the original Comet 4, which gave it a longer range than the 4B. Free shipping. [123] The shape of the passenger windows were not indicated in any failure mode detailed in the accident report and were not viewed as a contributing factor. Prototype Comet 1 Assembly Shop The fuselage sections and nose simulated a flight up to 70,000ft (21,000m) at a temperature of 70C (94F), with 2,000lb (910kg) pressure applications at 9psi (62kPa). 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. The next was at Karachi on 2 March 1953 when a Canadian Pacific Airlines Comet, on its delivery flight to Sydney, had a similar crash killing all on board, including some Australians. With a clientele composed mainly of wealthy people, luxury was the name of the game for these flights. After analysing route structures for the Comet, BOAC reluctantly cast about for a successor, and in 1956 entered into an agreement with Boeing to purchase the 707. [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. [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. 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. [49] The Comet's high cabin pressure and fast operating speeds were unprecedented in commercial aviation, making its fuselage design an experimental process. ", "De Havilland Comet 4B airliner, serial no 6438, 1960. The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. [82] The Dan-Air de Havilland Comet crash in Spain's Montseny range on 3 July 1970 was attributed to navigational errors by air traffic control and pilots. The overall flight takes under 30 hours. ", From 1944 to 1946, the design group prepared submissions on a three-engined twin-boom design, a three-engined canard design with engines mounted in the rear, and a tailless design that featured a. Oakey, Michael, ed. [17] The majority of hydraulic components were centred in a single avionics bay. The aircraft featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurized cabin, and large square windows. Mk.1. The failure then occurred longitudinally along a fuselage stringer at the widest point of the fuselage and through a cut out for an escape hatch. [198] Since the 2000s, several parties have proposed restoring Canopus, which is maintained by a staff of volunteers,[199] to airworthy, fully flight-capable condition. 106 Comet.". [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. All 43 on board were killed. 1963 De Havilland DH106 Comet 4C 'Canopus', serial number 6473, G-CDPA, formerly XS235, was the last Comet to remain flying and is now the only surviving Com. In 1967, BOAC introduced its own Pacific route to Australia via New York, San Francisco, Honolulu, and Fiji. [114] The fuselage frames did not have sufficient strength to prevent the crack from propagating. [63] Comet commercial flights would not resume until 1958. The need to inspect areas not easily viewable by the naked eye led to the introduction of widespread radiography examination in aviation; this also had the advantage of detecting cracks and flaws too small to be seen otherwise. 14.". [26] Both prototypes could be externally distinguished from later Comets by the large single-wheeled main landing gear, which was replaced on production models starting with G-ALYP by four-wheeled bogies. Free shipping for many products! G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. 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. [157], The Comet 1 was the first model produced, a total of 12 aircraft in service and test. This simply meant that the planes landed on solid ground at airports rather than water. ", Tony Fairbrother, manager, upgraded Comet development. These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. 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.

The De Havilland Comet was used on BOAC's transatlantic crossing Credit: Getty I t all started with a newspaper. [N 16] Professor Natesan Srinivasan joined the inquiry as the main technical expert. [116] Based on these findings, Comet 1 structural failures could be expected at anywhere from 1,000 to 9,000 cycles. [155] Boeing stated that podded engines were selected for their passenger airliners because buried engines carried a higher risk of catastrophic wing failure in the event of engine fire. [138], 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 Europe, and East African Airways received three new Comet 4s from 1960 to 1962 and operated them to the United Kingdom and to Kenya, Tanzania, and Uganda. 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. "Jet Jubilee (Part 1)". On 10 January 1954, the flight took off at 09:34 GMT for the final-stage flight to London. The individual pieces of luggage and cargo also had to be retrieved in a similarly slow manner at the arriving airport. BOAC chmn Guthrie orders rev of co's routes. Trischler, Helmuth and Stefan Zeilinger, eds. [124] Paul Withey, Professor of Casting at the University of Birmingham School of Metallurgy states in a video presentation delivered in 2019, analysing all available data that: "The fact that DeHavilland put oval windows into later marks, is not because of any 'squareness' of the windows that caused failure. [64][65], The earliest production aircraft, registered G-ALYP ("Yoke Peter"), first flew on 9 January 1951 and was subsequently lent to BOAC for development flying by its Comet Unit. [71] As well as the sales to BOAC, two French airlines, Union Aromaritime de Transport and Air France, each acquired three Comet 1As, an upgraded variant with greater fuel capacity, for flights to West Africa and the Middle East. The MoT subsequently backed BOAC's order of Conway-powered Boeing 707s. [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. [82], Since retirement, three early-generation Comet airframes have survived in museum collections. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. [13][18][19] The entire forward fuselage section was tested for metal fatigue by repeatedly pressurising to 2.75 pounds per square inch (19.0kPa) overpressure and depressurising through more than 16,000 cycles, equivalent to about 40,000 hours of airline service. [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. Most commonly quoted are the 'square' passenger windows. [169] The Comet 3 was destined to remain a development series since it did not incorporate the fuselage-strengthening modifications of the later series aircraft, and was not able to be fully pressurised. All outstanding orders for the Comet 2 were cancelled by airline customers. BOAC took delivery of 10 Comets and the first passenger service opened to Johannesburg on 2 May 1952. 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. G-ALYR a/f 6004. In 1962, BOAC and the British steamship company Cunard formed BOAC-Cunard Ltd, operating services to North America, the Caribbean and South America. Specialised signals intelligence and electronic surveillance capability was later added to some airframes. Hall's team began considering fatigue as the most likely cause of both accidents and initiated further research into measurable strain on the aircraft's skin.
