[82] Three fatal Comet 1 crashes due to structural problems, specifically BOAC Flight 783 on 2 May 1953, BOAC Flight 781 on 10 January 1954 and South African Airways Flight 201 on 8 April 1954, led to the grounding of the entire Comet fleet. [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. 1961: West express A new Qantas route from London to Perth has refuelling stops in Tehran, Karachi,. [188] Other fatal Comet 4 accidents included a British European Airways crash in Ankara, Turkey, following instrument failure on 21 December 1961, a United Arab Airlines Flight 869 crash during inclement weather near Bombay, India, on 28 July 1963, and the terrorist bombing of Cyprus Airways Flight 284 off the Turkish coast on 12 October 1967.

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. 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. [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. LONDON, Jan. 2 (ReutersSir Giles Guthrie, new c hairman of the publicIy owned British Overseas Airways Corporation has ordered a review of the . Specialised signals intelligence and electronic surveillance capability was later added to some airframes. For the 1930s racing aircraft, see, "Comet (aircraft)" redirects here. G-ALYP Author. [67] On 2 May 1952, as part of BOAC's route-proving trials, G-ALYP took off on the world's first jetliner[N 14] flight with fare-paying passengers and inaugurated scheduled service from London to Johannesburg. ", "On This Day: Comet inaugurates the jet age.". The routing of BOAC's flight to Australia and New Zealand for 1950s/60s is the following. 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. [147] The Bruntingthorpe Aerodrome also displays a related Hawker Siddeley Nimrod MR2 aircraft. 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. A year later, the second prototype G-5-2 made its maiden flight. [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. This is at your risk. FOR SALE! [115] A further test reproduced the same results. [164] The first production aircraft (G-AMXA) flew on 27 August 1953. Crews on this route were given military status due to the operations in military regions. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . Also in that year the Comet route to New York was extended to Nassau and Montego Bay. [28] Two pairs of turbojet engines (on the Comet 1s, Halford H.2 Ghosts, subsequently known as de Havilland Ghost 50 Mk1s) were buried into the wings. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. . 1969. "[57], "I don't think it is too much to say that the world changed from the moment the Comet's wheels left the ground. Registered 18/09/1951 to de Havilland Aircraft Company. [141] The last Comet 4 variant, the Comet 4C, first flew on 31 October 1959 and entered service with Mexicana in 1960. Engineers at de Havilland immediately recommended 60 modifications aimed at any possible design flaw, while the Abell Committee met to determine potential causes of the crash. 106 Comet.". [37] The navigator occupied a dedicated station, with a table across from the flight engineer. canuck DC-8. [113], The RAE also reconstructed about two-thirds of G-ALYP at Farnborough and found fatigue crack growth from a rivet hole at the low-drag fibreglass forward aperture around the Automatic Direction Finder, which had caused a catastrophic break-up of the aircraft in high-altitude flight. [13] Sprite fittings were retained on production aircraft. In 1962, BOAC and the British steamship company Cunard formed BOAC-Cunard Ltd, operating services to North America, the Caribbean and South America. [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. The first in a dramatic series of crashes of the DH106 Comet was at Rome on 26 October 1952 when a BOAC aircraft failed to get properly airborne in taking off. Oakey, Michael, ed. [52], Operationally, the design of the cargo holds led to considerable difficulty for the ground crew, especially baggage handlers at the airports. [citation needed], The Comet 4 first flew on 27 April 1958 and received its Certificate of Airworthiness on 24 September 1958; the first was delivered to BOAC the next day. [18] Tracing fuselage failure points proved difficult with this method,[18] and de Havilland ultimately switched to conducting structural tests with a water tank that could be safely configured to increase pressures gradually. [82], Both early accidents were originally attributed to pilot error, as over-rotation had led to a loss of lift from the leading edge of the aircraft's wings. This artificial feel was the first of its kind to be introduced in any aircraft. BOAC DE HAVILLAND COMET 4 RADIO MAINTENANCE SCHEDULE - ORIGINAL AND RARE 384272193709 [82], Other operators used the Comet either through leasing arrangements or through second-hand acquisitions. Delivered to British Overseas Airways Corporation (B.O.A.C.) ", "De Havilland Comet 4C G-BDIX Interior View Scottish Museum of Flight. [57] The Comet's buried-engine configuration increased its structural weight and complexity. BOAC Flight 781. 2 March. "World Beater: Homage to the DH. [38], Several of the Comet's avionics systems were new to civil aviation. 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. Green and Swanborough April 1977, p. 174. BOAC DE HAVILLAND Comet 4 Radio Maintenance Schedule - Original And Rare - $73.31. [34][N 11] For passengers used to propeller-driven airliners, smooth and quiet jet flight was a novel experience. [107][108] The forensic reconstruction effort had just begun when the Abell Committee reported its findings. At about 09:50 GMT BOAC Argonaut, G-ALHJ piloted by Captain Johnson, which was flying the same route at a lower altitude was in contact with Captain Gibson. [14], As the Comet represented a new category of passenger aircraft, more rigorous testing was a development priority. The Ministry of Supply's order for DH 108s was listed as Operational Requirement OR207 to Specification E.18/45. As a result, de Havilland re-profiled the wings' leading edge with a pronounced "droop",[88] and wing fences were added to control spanwise flow. ST-AAX Comet 4C. BOAC then started flying Short S25 Sunderland III flying boats to West Africa. Surviving Comet 1s can be seen on view at the RAF Museum Cosford and the DeHavilland Museum at Salisbury Hall, London Colney. 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. BOAC flew two de Havilland Comet 4 aircraft between London and New York International Airport, Idlewild. The Comet 1 airliner roared into the air and into historyon 20,000 pounds of thrust from its four De Havilland Ghost jet engines. Menu. As BOAC introduced the world to the Comet 4 and air travel to the world at the dawn of the jet age, they left tyre tracks across a game park in Kenya, a trail of sparks at both Stansted in Essex and Rome, stripped trees of their leaves in Rome (again), and reduced the elevation of a hill outside Madrid by a foot or so. 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. [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. "The de Havilland Comet Srs. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. 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. 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. Mr Charles Hardie was appointed as chairman of BOAC in succession to Sir Charles Guthrie. All 43 on board were killed. (from the structure)[126]. Smith, Adrian. [186] Pilot error was blamed for the type's first fatal accident, which occurred during takeoff at Karachi, Pakistan, on 3 March 1953 and involved a Canadian Pacific Airlines Comet 1A. The first Comet 4B flew on 27 June 1959 and BEA began Tel Aviv to London-Heathrow services on 1 April 1960. By 1965 with the departure of both the Comet and Britannia fleets the BOAC route network was served by just two types, the Boeing 707 and the Vickers VC10. [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. [146] On 14 March 1997 a Comet 4C serial XS235 and named Canopus,[147] which had been acquired by the British Ministry of Technology and used for radio, radar and avionics trials, made the last documented production Comet flight. [31] Large picture window views and table seating accommodations for a row of passengers afforded a feeling of comfort and luxury unusual for transportation of the period. [168] The variant added wing pinion tanks, and offered greater capacity and range. There was accommodation for 36 passengers in two cabins and pressurization enabled it to fly at levels over 12,000m (40,000 feet). The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . Comet Lost: Services Suspended. For the first time ever, a jet-propelled aircraft was carrying. [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. BOAC's requested capacity increase was known as Specification 22/46. Last edited on 23 February 2023, at 18:58, Netaji Subhash Chandra Bose International Airport, "Comet Engineering: The Performance of Airframe, Engines, and Equipment in Operational Service. While Captain Alan Gibson was taking . It was on that date when a BOAC Comet departed from Rome and climbed to 26,000 feet and attempted to reach 36,000 feet. 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. 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. Jones, Barry. [15] Replacing previously specified Halford H.1 Goblin engines, four new, more-powerful Rolls-Royce Avons were to be incorporated in pairs buried in the wing roots; Halford H.2 Ghost engines were eventually applied as an interim solution while the Avons cleared certification. 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. [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. Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. [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. [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. ", "ASN Aircraft accident de Havilland DH-106 Comet 4 G-APDN Sierra del Montseny", "de Havilland DH106 Comet 1A de Havilland Aircraft Museum", "Gate Guardian Comet C2 Sagittarius XK699 RAF Lyneham. The de Havilland Comet 4 aircraft reduced the flight time between London and New York to seven hours - significantly less than the 18-20 hours it took on the Boeing Stratocruiser With a clientele composed mainly of wealthy people, luxury was the name of the game for these flights. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. BOAC proudly served during the war. In 1967, BOAC introduced its own Pacific route to Australia via New York, San Francisco, Honolulu, and Fiji. The Feb 1959 OAG shows eight transatlantic Comets a week out of London, plus 10 BOAC Britannias and 11 DC-7Cs. [105] The first pieces of wreckage were discovered on 12 February 1954[106] and the search continued until September 1954, by which time 70 percent by weight of the main structure, 80 percent of the power section, and 50 percent of the aircraft's systems and equipment had been recovered. First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. [76] Popular Mechanics wrote that Britain had a lead of three to five years on the rest of the world in jetliners. $430.00. 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. [94], The inquiry's recommendations revolved around the enforcement of stricter speed limits during turbulence, and two significant design changes also resulted: all Comets were equipped with weather radar and the "Q feel" system was introduced, which ensured that control column forces (invariably called stick forces) would be proportional to control loads. The return flight left Tokyo on the 4th arriving at London on the 5th. VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. The cargo hold had its doors located directly underneath the aircraft, so each item of baggage or cargo had to be loaded vertically upwards from the top of the baggage truck, then slid along the hold floor to be stacked inside. [8] First-phase development of the DH.106 focused on short- and intermediate-range mailplanes with small passenger compartments and as few as six seats, before being redefined as a long-range airliner with a capacity of 24 seats. 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. Worldwide International 134457089011 [133][134] The base price of a new Comet 4 was roughly 1.14 million (24.81 million in 2019). Hill, Malcolm L. "de Havilland's Comet: Pushing the Boundaries.". VENDRE! [69][70][71] The final Comet from BOAC's initial order, registered G-ALYZ, began flying in September 1952 and carried cargo along South American routes while simulating passenger schedules. Prototype Comet 1 Assembly Shop [98] With the recovery of large sections of G-ALYP from the Elba crash and BOAC's donation of an identical airframe, G-ALYU, for further examination, an extensive "water torture" test eventually provided conclusive results. A countersunk bolt hole and manufacturing damage that had been repaired at the time of construction using methods that were common, but were likely insufficient allowing for the stresses involved, were both located along the failure crack. ", This page was last edited on 23 February 2023, at 18:58. [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. The Abell Committee, named after chairman C. Abell, Deputy Operations Director (Engineering) of BOAC, consisted of representatives of the Allegation Review Board (A.R.B. The Comet Story. The trip took 33 hours. 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. XK695 Comet 2R. [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952. 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. 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. 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. [74], In their first year, Comets carried 30,000 passengers. In August 1953 BOAC scheduled nine-stop London to Tokyo flights by Comet for 36 hours, compared to 86 hours and 35 minutes on their Argonaut piston airliner. Pen and Sword, 2013. The first flight of Concorde 001 from Toulouse, France took place and was shortly followed by Concorde 002 from Filton . [N 2] As a result, committee member Sir Geoffrey de Havilland, head of the de Havilland company, used his personal influence and his company's expertise to champion the development of a jet-propelled aircraft; proposing a specification for a pure turbojet-powered design. These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. ", 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. [10][153] The Comet's buried engines were used on some other early jet airliners, such as the Tupolev Tu-104,[154] but later aircraft, such as the Boeing 707 and Douglas DC-8, differed by employing podded engines held on pylons beneath the wings. The Comet was painted in BOAC livery in July 1978 and transported to the Museum on 17 September 1978 where it is currently on display. [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. 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. In November 1965, BOAC retired its Comet 4s from revenue service; other operators continued commercial passenger flights with the Comet until 1981. 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. "[121], Despite findings of the Cohen Inquiry, a number of myths have evolved around the cause of the Comet 1's accidents. Unlike drill riveting, the imperfect nature of the hole created by punch-riveting could cause fatigue cracks to start developing around the rivet. [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. [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. On Sunday 10 January 1954, British Overseas Airways Corporation Flight 781, a de Havilland DH.106 Comet 1, registered G-ALYP, [1] 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. On October 4th, 1958, a British Overseas Aircraft Corporation ( BOAC) de Havilland DH.106 Comet conducted the first-ever regularly scheduled commercial jetliner transatlantic crossing. G-ALYR a/f 6004. According to Charles Woodley's 'BOAC, an illustrated history' the Comet 4 was used on routes to South America from 1960 on. 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. The number one route was still the famous 'Kangaroo Route', which since 1947 was operated in a profit-sharing partnership with BOAC, but the airline also had routes to Hong Kong, Japan and South Africa plus now BCPA's network too. [103], "The cost of solving the Comet mystery must be reckoned neither in money nor in manpower. Winchester, Jim, ed. [56], Placing the engines within the wings had the advantage of a reduction in the risk of foreign object damage, which could seriously damage jet engines. de Havilland Comet 1 jet airliner . [82][178][181] BEA's Comet 4Bs were chartered by Cyprus Airways, Malta Airways and Transportes Areos Portugueses. [5] Aviation company de Havilland was interested in this requirement, but chose to challenge the then widely held view that jet engines were too fuel-hungry and unreliable for such a role. The American jets were larger, faster, longer-ranged and more cost-effective than the Comet. [197], The last Comet to fly, Comet 4C Canopus (XS235),[1] is kept in running condition at Bruntingthorpe Aerodrome, where fast taxi-runs are regularly conducted. The de Havilland DH.106 Comet was the world's first commercial jet airliner. "Database: D.H. 106 Comet". [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). [9], "During the next few years, the UK has an opportunity, which may not recur, of developing aircraft manufacture as one of our main export industries. [85], On 26 October 1952, the Comet suffered its first hull loss when a BOAC flight departing Rome's Ciampino airport failed to become airborne and ran into rough ground at the end of the runway. [20] One window frame survived 100psi (690kPa),[21] about 1,250 percent over the maximum pressure it was expected to encounter in service. Free shipping. [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. On 10 January 1954, 20minutes after taking off from Ciampino, the first production Comet, G-ALYP, broke up in mid-air while operating BOAC Flight 781 and crashed into the Mediterranean off the Italian island of Elba with the loss of all 35 on board. [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. Trischler, Helmuth and Stefan Zeilinger, eds. (Cohen Inquiry accident report Fig 7). Nigeria Airways timetable August 1965 - page 1 [111][185] The Royal Canadian Air Force also operated Comet 1As (later retrofitted to 1XB) through its 412 Squadron from 1953 to 1963. BOAC said, "the Comet 4 was largely responsible for the fact that between April 1 st and September 19 th traffic was up by 40% on the North Atlantic compared to the summer period of 1958. [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. On October 4th, 1958, a British Overseas Aircraft Corporation ( BOAC) de Havilland DH.106 Comet conducted the first-ever regularly scheduled commercial jetliner transatlantic crossing. 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. On the 10 th December R. Clear commanded test flights from Hatfield. The prototype Comet 3 first flew in July 1954 and was tested in an unpressurised state pending completion of the Cohen inquiry. Fuselage alloys detailed in Directorate of Technical Development 564/L.73 and DTD 746C/L90. [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. BOAC's trans-Atlantic COMET 4 services .. on the London/New York/London route (only) were relatively short-lived .. being replaced by B707-420's in competition with PAN AM B707-320's on this most prestigeous of airline routes and from around 1961. Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. [110] The Comet's Certificate of Airworthiness was revoked, and Comet 1 line production was suspended at the Hatfield factory while the BOAC fleet was permanently grounded, cocooned and stored. In later years we realised that these were the indications of how flimsy the structure really was. The wing was drastically redesigned from a 40 sweep. At the end of the month this Comet was brought back to Hatfield from Cambridge (Marshall's) where 'radio' mods were made (JH). All outstanding orders for the Comet 2 were cancelled by airline customers.

USA et International; Australie; Canada; France; Allemagne; Italie; Espagne; Royaume-Uni; Qui sommes-nous; In responding to the report de Havilland stated: "Now that the danger of high level fatigue in pressure cabins has been generally appreciated, de Havillands will take adequate measures to deal with this problem. Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. Four Ghost 50 Mk 1 engines were fitted (later replaced by more powerful Ghost DGT3 series engines). ", "De Havilland Comet 4B airliner, serial no 6438, 1960. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes). The redesigned aircraft was named the DH.106 Comet in December 1947. [184], In military service, the United Kingdom's Royal Air Force was the largest operator, with 51 Squadron (19581975; Comet C2, 2R), 192 Squadron (19571958; Comet C2, 2R), 216 Squadron (19561975; Comet C2 and C4), and the Royal Aircraft Establishment using the aircraft. The Comet was withdrawn from service and extensively tested. Singapore arrival mark on back. [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.
