[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. 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. XK695 Comet 2R. BOAC chmn Guthrie orders rev of co's routes. [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. [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. FOR SALE! Registered 18/09/1951 to de Havilland Aircraft Company. Winchester, Jim, ed. [32] Amenities included a galley that could serve hot and cold food and drinks, a bar, and separate men's and women's toilets. The Comet 1 was powered by four 2,018 kg thrust de Havilland Ghost turbojets buried in the wing roots. $39.99. 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. [53][54], The Comet was powered by two pairs of turbojet engines buried in the wings close to the fuselage. "[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." [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). Oakey, Michael, ed. 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. Investigators did not consider metal fatigue as a contributory cause. ), BOAC, and de Havilland. [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. [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. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. [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. The inquiries into the accidents that plagued the Comet 1 were perhaps some of the most extensive and revolutionary that have ever taken place, establishing precedents in accident investigation; many of the deep-sea salvage and aircraft reconstruction techniques employed have remained in use within the aviation industry. The de Havilland DH.106 Comet was the world's first commercial jet airliner. While Captain Alan Gibson was taking . VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. 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. ", Tony Fairbrother, manager, upgraded Comet development. [140] Deliveries to BOAC began on 30 September 1958 with two 48-seat aircraft, which were used to initiate the first scheduled transatlantic services. [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. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. Ordered by Kuwait Airways, Middle East Airlines, Misrair (later United Arab Airlines), and Sudan Airways, it was the most popular Comet variant. [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. Vintage BOAC Airlines travel . 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. Though these lessons could be implemented on the drawing board for future aircraft, corrections could only be retroactively applied to the Comet. USA et International; Australie; Canada; France; Allemagne; Italie; Espagne; Royaume-Uni; Qui sommes-nous; [135] The Comet 4 enabled BOAC to inaugurate the first regular jet-powered transatlantic services on 4 October 1958 between London and New York (albeit still requiring a fuel stop at Gander International Airport, Newfoundland, on westward North Atlantic crossings). [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. 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. "Report of the court investigation on the accident to COMET G-ALYV", "B.O.A.C. [168] The variant added wing pinion tanks, and offered greater capacity and range. BOAC DE HAVILLAND COMET 4 RADIO MAINTENANCE SCHEDULE - ORIGINAL AND RARE 384272193709 ", Withuhn, Bill. SA on 22 nd January 1952. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. 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. 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. Simons, Graham M. "Comet! In command was Capt Tom Stoney, manager of BOAC's Comet Flight. 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. or Best Offer. [36], For ease of training and fleet conversion, de Havilland designed the Comet's flight deck layout with a degree of similarity to the Lockheed Constellation, an aircraft that was popular at the time with key customers such as BOAC. 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. Brand New. The Approximate London, Frankfurt, Rome, Athens, Cairo, Khartoum, Entebbe, Nairobi, Livingstone, Johannesburg Route Operated By BOAC DH COMET 1 Aircraft During The Early/Mid 1950's: . Avon-powered Comets were distinguished by larger air intakes and curved tailpipes that reduced the thermal effect on the rear fuselage. [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. [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. [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. [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. First production Comet for BOAC. BOAC then started flying Short S25 Sunderland III flying boats to West Africa. All but four Comet 2s were allocated to the RAF, deliveries beginning in 1955. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. ", GB-High Wycombe: "Dismantlement and relocation of Gate Guardian Comet C2 XK699. A large portion of the aircraft was recovered and reassembled at Farnborough,[93] during which the break-up was found to have begun with a left elevator spar failure in the horizontal stabilizer. [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. [15] The Comet 4 was considered the definitive series, having a longer range, higher cruising speed and higher maximum takeoff weight. ", "De Havilland Comet 4C G-BDIX Interior View Scottish Museum of Flight. 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. 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. [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. Initially used for development, training and route proving before the inaugural jet service to Jo,burg. Comets quit flying the North Atlantic in October 1960 (but reportedly made a few flights in summer 1964). Witnesses observed the wingless Comet on fire plunging into the village of Jagalgori,[92] leading investigators to suspect structural failure. [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).
