The last two Comet 4C fuselages were used to build prototypes of the Hawker Siddeley Nimrod maritime patrol aircraft. [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. Trischler, Helmuth and Stefan Zeilinger, eds. 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. [49] The Comet's high cabin pressure and fast operating speeds were unprecedented in commercial aviation, making its fuselage design an experimental process. First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. [162] Design changes had been made to make the aircraft more suitable for transatlantic operations. On its return leg from Singapore it landed at Calcutta-Dum Dum Airport at 15:10 hrs local time. [145], In the 1960s, orders declined, a total of 76 Comet 4s being delivered from 1958 to 1964. 1 November: The inaugural flight of a BOAC De Havilland Comet 4 aircraft on the London to Sydney route took place. [N 22][163] A total of 12 of the 44-seat Comet 2s were ordered by BOAC for the South Atlantic route. 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. [13], In September 1946, before completion of the DH 108s, BOAC requests necessitated a redesign of the DH.106 from its previous 24-seat configuration to a larger 36-seat version. Explore our past: 1969. ", 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. The American jets were larger, faster, longer-ranged and more cost-effective than the Comet.

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 . The first flight of Concorde 001 from Toulouse, France took place and was shortly followed by Concorde 002 from Filton . For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. As a result, the Comet was extensively redesigned, with oval windows, structural reinforcements and other changes. [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. To this end we propose to use thicker gauge materials in the pressure cabin area and to strengthen and redesign windows and cut outs and so lower the general stress to a level at which local stress concentrations either at rivets and bolt holes or as such may occur by reason of cracks caused accidentally during manufacture or subsequently, will not constitute a danger. 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. 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. [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. [18] The cockpit included full dual-controls for the captain and first officer, and a flight engineer controlled several key systems, including fuel, air conditioning and electrical systems. [82][178][181] BEA's Comet 4Bs were chartered by Cyprus Airways, Malta Airways and Transportes Areos Portugueses. 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. 2 March. ", "Report of the Public Inquiry into the causes and circumstances of the accident which occurred on the 10 January 1954, to the Comet aircraft G-ALYP, Part IX (c): Action taken after the accident and prior to the accident to Comet G-ALYY: Naval search for wreckage. [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. All 43 on board were killed. [27] The Ghost engines allowed the Comet to fly above weather that competitors had to fly through. The return flight to London took place three days later, on May 5, 1952. There was accommodation for 36 passengers in two cabins and pressurization enabled it to fly at levels over 12,000m (40,000 feet). [15] The Comet 4 was considered the definitive series, having a longer range, higher cruising speed and higher maximum takeoff weight. Unlike drill riveting, the imperfect nature of the hole created by punch-riveting could cause fatigue cracks to start developing around the rivet. [50] The chemical bonding process was accomplished using a new adhesive, Redux, which was liberally used in the construction of the wings and the fuselage of the Comet; it also had the advantage of simplifying the manufacturing process. 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. [119], It was also found that the punch-rivet construction technique employed in the Comet's design had exacerbated its structural fatigue problems;[98] the aircraft's windows had been engineered to be glued and riveted, but had been punch-riveted only. [141] The last Comet 4 variant, the Comet 4C, first flew on 31 October 1959 and entered service with Mexicana in 1960. 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. Comet Lost: Services Suspended. OK condition, with wear. Airline Mug BOAC British Overseas Airways Corporation 5" Ceramic. Nigeria Airways timetable August 1965 - page 1 Surviving Comet 1s can be seen on view at the RAF Museum Cosford and the DeHavilland Museum at Salisbury Hall, London Colney. [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. Brand New. BOAC then started flying Short S25 Sunderland III flying boats to West Africa. 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. VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. In 1967, BOAC introduced its own Pacific route to Australia via New York, San Francisco, Honolulu, and Fiji. Winchester, Jim, ed. [24], The prototype was registered G-ALVG just before it was publicly displayed at the 1949 Farnborough Airshow before the start of flight trials. Before the Elba accident, G-ALYP had made 1,290 pressurised flights, while G-ALYY had made 900 pressurised flights before crashing. As the aircraft could be profitable with a load factor as low as 43 percent, commercial success was expected. On 10 January 1954, the flight took off at 09:34 GMT for the final-stage flight to London. [82] In response, Canadian Pacific cancelled its remaining order for a second Comet 1A and never operated the type in commercial service. [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. [76] Popular Mechanics wrote that Britain had a lead of three to five years on the rest of the world in jetliners. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. 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: . USA et International; Australie; Canada; France; Allemagne; Italie; Espagne; Royaume-Uni; Qui sommes-nous; At about 10:00 GMT, the aircraft suffered an explosive decompression . 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. 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. G-ALYP Author. ST-AAX Comet 4C. [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. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. 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. 106 Comet.". [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. [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. [132] Capital's order included 10 Comet 4As, a variant modified for short-range operations with a stretched fuselage and short wings, lacking the pinion (outboard wing) fuel tanks of the Comet 4. [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. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes.) vs 315mph (507km/h), respectively), and a faster rate of climb further cut flight times. "Jet Jubilee (Part 1)". [102] Comet flights resumed on 23 March 1954. ", Tony Fairbrother, manager, upgraded Comet development. [170] Only two Comet 3s began construction; G-ANLO, the only airworthy Comet 3, was demonstrated at the Farnborough SBAC Show in September 1954. 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. "[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. Following its first flight, the special order Comet 4C was described as "the world's first executive jet. The de Havilland DH.106 Comet was the world's first commercial jet airliner. The De Havilland Comet was used on BOAC's transatlantic crossing Credit: Getty I t all started with a newspaper. Among those also on board were the respective BOAC and de Havilland managing directors, Basil Smallpeice and Aubrey Burke. In November 1965, BOAC retired its Comet 4s from revenue service; other operators continued commercial passenger flights with the Comet until 1981. 1969. The Comet 1 airliner roared into the air and into historyon 20,000 pounds of thrust from its four De Havilland Ghost jet engines. Although G-APAS never flew in BOAC markings, this colour scheme is representative of the first ever fleet of passenger jet aircraft. 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. In command was Capt Tom Stoney, manager of BOAC's Comet Flight. [39] Many of the control surfaces, such as the elevators, were equipped with a complex gearing system as a safeguard against accidentally over-stressing the surfaces or airframe at higher speed ranges. [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. [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. ", Prime Minister Winston Churchill, 1954. Delivered to British Overseas Airways Corporation (B.O.A.C.) BOAC took delivery of 10 Comets and the first passenger service opened to Johannesburg on 2 May 1952. 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. Menu. Both of these aeroplanes would continue to operate side by side until the formation of British Airways PLC in 1974. Though these lessons could be implemented on the drawing board for future aircraft, corrections could only be retroactively applied to the Comet. Herman. [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 October 4th, 1958, a British Overseas Aircraft Corporation ( BOAC) de Havilland DH.106 Comet conducted the first-ever regularly scheduled commercial jetliner transatlantic crossing. [29], The original Comet was the approximate length of, but not as wide as, the later Boeing 737-100, and carried fewer people in a significantly more-spacious environment. This simply meant that the planes landed on solid ground at airports rather than water. BOAC de Havilland Comet 1 Jet Airliner Colour Card FB12P: $4.86. 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. [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. 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. Sections of pressurised fuselage were subjected to high-altitude flight conditions via a large decompression chamber on-site [N 10] and tested to failure. [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. 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. [12] The DH 108s were later modified to test the DH.106's power controls. 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. Crews on this route were given military status due to the operations in military regions. G-ALYR a/f 6004. 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. 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. ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. . According to Charles Woodley's 'BOAC, an illustrated history' the Comet 4 was used on routes to South America from 1960 on. [150] Cunningham likened the Comet to the later Concorde and added that he had assumed that the aircraft would change aviation, which it subsequently did. [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.

Investigators did not consider metal fatigue as a contributory cause. [144] In 1960, as part of a government-backed consolidation of the British aerospace industry, de Havilland itself was acquired by Hawker Siddeley, within which it became a wholly owned division. Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. [139] The Comet 4A ordered by Capital Airlines was instead built for BEA as the Comet 4B, with a further fuselage stretch of 38in (970mm) and seating for 99 passengers. [93], After the loss of G-ALYV, the Government of India convened a court of inquiry[92] to examine the cause of the accident. Free shipping for many products! [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. Fuselage alloys detailed in Directorate of Technical Development 564/L.73 and DTD 746C/L90. [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. The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. [28], One of the most striking aspects of Comet travel was the quiet, "vibration-free flying" as touted by BOAC. [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. de Havilland Comet 1 jet 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.
