"World Beater: Homage to the DH. [82], Other operators used the Comet either through leasing arrangements or through second-hand acquisitions. The skin thickness was discovered to be insufficient to distribute the load across the structure, leading to overloading of fuselage frames adjacent to fuselage cut outs. ", GB-High Wycombe: "Dismantlement and relocation of Gate Guardian Comet C2 XK699. 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. VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. FOR SALE! Davies and Birtles 1999, p. 22 (Route map illustration). At the end of the month this Comet was brought back to Hatfield from Cambridge (Marshall's) where 'radio' mods were made (JH). XK695 Comet 2R. 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. As a young woman, Thorne . [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.

[124] In fact, the Comet 1's window general shape resembles a slightly larger Boeing 737 window mounted horizontally. This simply meant that the planes landed on solid ground at airports rather than water. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. 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. After design modifications were implemented, Comet services resumed on October 4, 1958 with Comet 4s. 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. The committee concluded that fire was the most likely cause of the problem, and changes were made to the aircraft to protect the engines and wings from damage that might lead to another fire. Cone of Silence was made into a film in 1960, and Beaty also recounted the story of the Comet's takeoff accidents in a chapter of his non-fiction work, Strange Encounters: Mysteries of the Air (1984). 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. With a clientele composed mainly of wealthy people, luxury was the name of the game for these flights. [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 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. The court acted under the provisions of Rule 75 of the Indian Aircraft Rules 1937. 1 November: The inaugural flight of a BOAC De Havilland Comet 4 aircraft on the London to Sydney route took place. 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. BOAC South Pacific Route Menu, New York - 204250723949 In fact the mention of 'windows' in the Cohen report's conclusion, refers specifically to the origin point of failure in the ADF Antenna cut-out 'windows', located above the cockpit, not passenger windows. Was: $999.99 57% off. FOR SALE! Extensively modified at the factory, the aircraft included a VIP front cabin, a bed, special toilets with gold fittings and was distinguished by a green, gold and white colour scheme with polished wings and lower fuselage that was commissioned from aviation artist John Stroud.

When retired in 1973, the airframe was used for foam-arrester trials before the fuselage was salvaged at BAE Woodford, to serve as the mock-up for the Nimrod.[172]. [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. 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. The Comet gave BOAC four years lead in modern jet airliners over the rest of the world. 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. 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. 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. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. BOAC Comet 4 Captains Folder Africa routes original 1960s document Comet 4[edit] 304755204133. 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. Crashed near Elba 10/1/54. [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. [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. [83] Financial problems and a takeover by United Airlines meant that Capital would never operate the Comet. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. Design and construction flaws, including improper riveting and dangerous concentrations of stress around some of the square windows, were ultimately identified. [98] The Comet fleet was immediately grounded once again and a large investigation board was formed under the direction of the Royal Aircraft Establishment (RAE). "Preludes and Overtures: de Havilland Comet 1". [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. ", Tony Fairbrother, manager, upgraded Comet development. [55] The engines were outfitted with baffles to reduce noise emissions, and extensive soundproofing was also implemented to improve passenger conditions. [17] The majority of hydraulic components were centred in a single avionics bay. [165] Although these aircraft performed well on test flights on the South Atlantic, their range was still not suitable for the North Atlantic. [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. Brand New. "De Havilland DH.106 Comet. [157], The Comet 1 was the first model produced, a total of 12 aircraft in service and test. The MoT subsequently backed BOAC's order of Conway-powered Boeing 707s. Courtesy British Airways. Also in that year the Comet route to New York was extended to Nassau and Montego Bay. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. At about 10:00 GMT, the aircraft suffered an explosive decompression . [140] Olympic Airways was the only other customer to order the type. 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. In later years we realised that these were the indications of how flimsy the structure really was. [109], On 8 April 1954, Comet G-ALYY ("Yoke Yoke"), on charter to South African Airways, was on a leg from Rome to Cairo (of a longer route, SA Flight 201 from London to Johannesburg), when it crashed in the Mediterranean near Naples with the loss of all 21 passengers and crew on board. [38], Several of the Comet's avionics systems were new to civil aviation. [88], On 19 October 1954, the Cohen Committee was established to examine the causes of the Comet crashes. [20] The windows were also tested under a pressure of 12psi (83kPa), 4.75psi (32.8kPa) above expected pressures at the normal service ceiling of 36,000ft (11,000m). [156] In response to the Comet tragedies, manufacturers also developed ways of pressurisation testing, often going so far as to explore rapid depressurisation; subsequent fuselage skins were of a greater thickness than the skin of the Comet. [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. [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. Unlike drill riveting, the imperfect nature of the hole created by punch-riveting could cause fatigue cracks to start developing around the rivet. The operation was short-lived and was dissolved in 1966. [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. [82] In response, Canadian Pacific cancelled its remaining order for a second Comet 1A and never operated the type in commercial service. Airline Mug BOAC British Overseas Airways Corporation 5" Ceramic. They were bound for Idlewild via a stop at Gander, Newfoundland, which would be commonplace on eastbound flights. 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. The De Havilland Comet was used on BOAC's transatlantic crossing Credit: Getty I t all started with a newspaper. 1961: West express A new Qantas route from London to Perth has refuelling stops in Tehran, Karachi,. [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 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. First production Comet for BOAC. The de Havilland DH.106 Comet was the world's first commercial jet airliner. ST-AAX Comet 4C. [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. Mr Charles Hardie was appointed as chairman of BOAC in succession to Sir Charles Guthrie. BOAC de Havilland Comet 1 Jet Airliner Colour Card FB12P: $4.86. Explore our past: 1969. [40], The Comet had a total of four hydraulic systems: two primaries, one secondary, and a final emergency system for basic functions such as lowering the undercarriage. [183] Dan-Air bought all of the surviving flyable Comet 4s from the late 1960s into the 1970s; some were for spares reclamation, but most were operated on the carrier's inclusive-tour charters; a total of 48 Comets of all marks were acquired by the airline. [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 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. [141] The last Comet 4 variant, the Comet 4C, first flew on 31 October 1959 and entered service with Mexicana in 1960. OK condition, with wear. Rival manufacturers heeded the lessons learned from the Comet when developing their own aircraft. Smith, Adrian. [168] The variant added wing pinion tanks, and offered greater capacity and range. [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. G-ALYP Author. 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. [51], When several of the fuselage alloys were discovered to be vulnerable to weakening via metal fatigue, a detailed routine inspection process was introduced. [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. Before the Elba accident, G-ALYP had made 1,290 pressurised flights, while G-ALYY had made 900 pressurised flights before crashing. Pen and Sword, 2013. [140] Deliveries to BOAC began on 30 September 1958 with two 48-seat aircraft, which were used to initiate the first scheduled transatlantic services. Prins, Franois. [131], Development flying and route proving with the Comet 3 allowed accelerated certification of what was destined to be the most successful variant of the type, the Comet 4. Depending on weight and temperature, cruise fuel consumption was 6 to 10kg (13 to 22lb) per nautical mile (1.2 miles; 1.9 km), the higher figure being at the lower altitude needed at high weight. G-ALYP a/f 6003. [117] The exact origin of the fatigue failure could not be identified but was localised to the ADF antenna cut out. Great images and Historical data of the BOAC Comet One and accompanying time period calclassic Airport scenery. 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. [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. This is at your risk. [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). Although G-APAS never flew in BOAC markings, this colour scheme is representative of the first ever fleet of passenger jet aircraft. [72] BOAC Comet 1 at Entebbe Airport, Uganda in 1952 Prince Philip returned from the Helsinki Olympic Games with G-ALYS on 4 August 1952. [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. A year later, the second prototype G-5-2 made its maiden flight. The Comet 1 airliner roared into the air and into historyon 20,000 pounds of thrust from its four De Havilland Ghost jet engines. 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. [133][134] The base price of a new Comet 4 was roughly 1.14 million (24.81 million in 2019). There was accommodation for 36 passengers in two cabins and pressurization enabled it to fly at levels over 12,000m (40,000 feet). On the Eastern route there was a 22% increase in traffic but on the Southern route only a 2% increase." BCPA had actually ordered three Comet 2s from de Havilland, although the agreement had never been fully finalised. The Sud-Est SE 530/532/535 Mistral (FB 53) was a single-seat fighter-bomber version of the de Havilland Vampire jet fighter, used by. The COMET 4 remained in BOAC trans-Atlantic service though as new north American destinations . [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. LONDON, Jan. 2 (ReutersSir Giles Guthrie, new c hairman of the publicIy owned British Overseas Airways Corporation has ordered a review of the . Green and Swanborough April 1977, p. 174. Now from a BOAC 1971 Timetable. [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. [34][N 11] For passengers used to propeller-driven airliners, smooth and quiet jet flight was a novel experience. Most commonly quoted are the 'square' passenger windows. Proctor, Jon, Mike Machat and Craig Kodera. [147] The Bruntingthorpe Aerodrome also displays a related Hawker Siddeley Nimrod MR2 aircraft. Vintage BOAC Airlines travel . The Monarch Service is the name BOAC used for the on board experience on routes across the Atlantic. FR. [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. [5] Out of all the Brabazon designs, the DH.106 was seen as the riskiest: both in terms of introducing untried design elements and for the financial commitment involved. [77][78] A slightly longer version of the Comet 1 with more powerful engines, the Comet 2, was being developed,[79] and orders were placed by Air India,[80] British Commonwealth Pacific Airlines,[81] Japan Air Lines,[82] Linea Aeropostal Venezolana,[82] and Panair do Brasil. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. 1945 November: The government announced plans for post-war air services which would be provided by three state corporations: BOAC to continue to operate routes to the Empire, Far East and North America, British European Airways ( BEA) to operate services to Europe and domestically within the United Kingdom, and British South American Airways 2 March. Registered 18/09/1951 to de Havilland Aircraft Company. $39.99. [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. [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)) [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. [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. Investigators did not consider metal fatigue as a contributory cause. [18] The prototype's maiden flight, out of Hatfield Aerodrome, took place on 27 July 1949 and lasted 31 minutes. [53][54], The Comet was powered by two pairs of turbojet engines buried in the wings close to the fuselage. [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. 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. [104], During the investigation, the Royal Navy conducted recovery operations. [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. [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. [5][N 6] With no time to develop the technology necessary for a proposed tailless configuration, Bishop opted for a more conventional 20-degree swept-wing design[N 7] with unswept tail surfaces, married to an enlarged fuselage accommodating 36 passengers in a four-abreast arrangement with a central aisle. [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. 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. Avon-powered Comets were distinguished by larger air intakes and curved tailpipes that reduced the thermal effect on the rear fuselage. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. Surviving Comet 1s can be seen on view at the RAF Museum Cosford and the DeHavilland Museum at Salisbury Hall, London Colney. Witnesses observed the wingless Comet on fire plunging into the village of Jagalgori,[92] leading investigators to suspect structural failure. Sponsored. [102], Media attention centred on potential sabotage;[88] other speculation ranged from clear-air turbulence to an explosion of vapour in an empty fuel tank. They ran smoothly and were less noisy than piston engines, had low maintenance costs and were fuel-efficient above 30,000ft (9,100m). or Best Offer. Hall: "In the light of known properties of the aluminium alloy D.T.D. 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. [173] This variant became the Hawker Siddeley Nimrod and production aircraft were built at the Hawker Siddeley factory at Woodford Aerodrome. [102] The prestigious nature of the Comet project, particularly for the British aerospace industry, and the financial impact of the aircraft's grounding on BOAC's operations both served to pressure the inquiry to end without further investigation. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. Some amazing Britannia footage, Stratocruisers & DC-7Cs too! [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. The last two Comet 4C fuselages were used to build prototypes of the Hawker Siddeley Nimrod maritime patrol aircraft. [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 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). No apparent fault in the aircraft was found,[N 19] and the British government decided against opening a further public inquiry into the accident.
