[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). [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. [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. 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 . In later years we realised that these were the indications of how flimsy the structure really was. [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. "[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. [97] Aviation author Bill Withuhn concluded that the Comet had pushed "'the state-of-the-art' beyond its limits. 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. [161] Following the Comet 1 disasters, these models were rebuilt with heavier-gauge skin and rounded windows, and the Avon engines featuring larger air intakes and outward-curving jet tailpipes. Singapore arrival mark on back. BOADICEA COMPUTER SYS at the best online prices at eBay! 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. [17] The majority of hydraulic components were centred in a single avionics bay. Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. [55] The engines were outfitted with baffles to reduce noise emissions, and extensive soundproofing was also implemented to improve passenger conditions. "[121], Despite findings of the Cohen Inquiry, a number of myths have evolved around the cause of the Comet 1's accidents. [112] This time, the entire fuselage was tested in a dedicated water tank that was built specifically at Farnborough to accommodate its full length. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . Winchester, Jim, ed. BOAC started the first regular round-the-world service by Britannia 312 aircraft, operating via San Francisco and Hong Kong. [37] The navigator occupied a dedicated station, with a table across from the flight engineer. (from the structure)[126]. 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. [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. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. ", "DH106 Comet 'Canopus' 'Fast Taxi Run' - Bruntingthorpe Cold War Jets (May 2018)", "Comet 4C: More Payload on Medium Stages. [194] A Comet 4B (G-APYD) is stored in a facility at the Science Museum at Wroughton in Wiltshire, England. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. Green, William and Gordon Swanborough, eds. The Feb 1959 OAG shows eight transatlantic Comets a week out of London, plus 10 BOAC Britannias and 11 DC-7Cs. Witnesses observed the wingless Comet on fire plunging into the village of Jagalgori,[92] leading investigators to suspect structural failure. [49], The Comet's thin metal skin was composed of advanced new alloys[N 13] and was both riveted and chemically bonded, which saved weight and reduced the risk of fatigue cracks spreading from the rivets. BOAC Comet 4 Captains Folder Africa routes original 1960s document Comet 4[edit] 304755204133. The last two Comet 4C fuselages were used to build prototypes of the Hawker Siddeley Nimrod maritime patrol aircraft. [74], In their first year, Comets carried 30,000 passengers. [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. This simply meant that the planes landed on solid ground at airports rather than water. [82][187], Pilot error resulting in controlled flight into terrain was blamed for five fatal Comet 4 accidents: an Aerolneas Argentinas crash near Asuncin, Paraguay, on 27 August 1959, Aerolneas Argentinas Flight 322 at Campinas near So Paulo, Brazil, on 23 November 1961, United Arab Airlines Flight 869 in Thailand's Khao Yai mountains on 19 July 1962, a Saudi Arabian Government crash in the Italian Alps on 20 March 1963, and United Arab Airlines Flight 844 in Tripoli, Libya, on 2 January 1971. 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. ", Tony Fairbrother, manager, upgraded Comet development. 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. LONDON, Jan. 2 (ReutersSir Giles Guthrie, new c hairman of the publicIy owned British Overseas Airways Corporation has ordered a review of the . They ran smoothly and were less noisy than piston engines, had low maintenance costs and were fuel-efficient above 30,000ft (9,100m). [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. BOAC SOUTH PACIFIC Route Airline Menu Ny -San Francisco-Honolulu-Nandi-Sydney - $38.98. 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. Green and Swanborough April 1977, p. 174. Although G-APAS never flew in BOAC markings, this colour scheme is representative of the first ever fleet of passenger jet aircraft. 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. [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. [27] The Ghost engines allowed the Comet to fly above weather that competitors had to fly through. 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. AUSTRALIA 1959 BOAC Comet 4 illustrato FFC da Sydney a Singapore - EUR 3,97. "Duxford's AirSpace opens". Now from a BOAC 1971 Timetable. [N 22][163] A total of 12 of the 44-seat Comet 2s were ordered by BOAC for the South Atlantic route. On 10 January 1954, the flight took off at 09:34 GMT for the final-stage flight to London. ", "Commercial Aircraft 1953: De Havilland Comet. 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. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. [17] From 1947 to 1948, de Havilland conducted an extensive research and development phase, including the use of several stress test rigs at Hatfield Aerodrome for small components and large assemblies alike. [104], During the investigation, the Royal Navy conducted recovery operations. BOAC DE HAVILLAND COMET 4 RADIO MAINTENANCE SCHEDULE - ORIGINAL AND RARE 384272193709 The five-stop flight from London to Johannesburg was scheduled for 21 hr 20 min. [57] The Comet's buried-engine configuration increased its structural weight and complexity. vs 315mph (507km/h), respectively), and a faster rate of climb further cut flight times. [63] Comet commercial flights would not resume until 1958. Initially used for development, training and route proving before the inaugural jet service to Jo,burg. Trischler, Helmuth and Stefan Zeilinger, eds. [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. 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. Jones, Barry. BOAC ordered 19 Comet 4s in March 1955, and American operator Capital Airlines ordered 14 Comets in July 1956. [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. [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. 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. ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. [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 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 . Fuselage alloys detailed in Directorate of Technical Development 564/L.73 and DTD 746C/L90. [102] Comet flights resumed on 23 March 1954. [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. [159], The Comet was involved in 26 hull-loss accidents, including 13 fatal crashes which resulted in 426 fatalities. This is at your risk. [32] Amenities included a galley that could serve hot and cold food and drinks, a bar, and separate men's and women's toilets. Delivered to British Overseas Airways Corporation (B.O.A.C.) [133][134] The base price of a new Comet 4 was roughly 1.14 million (24.81 million in 2019). 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. 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. ", Prime Minister Winston Churchill, 1954. Simons, Graham M. "Comet! 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: . 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. Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. [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. [82], Since retirement, three early-generation Comet airframes have survived in museum collections. "Report of the court investigation on the accident to COMET G-ALYV", "B.O.A.C. The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. [82], Nine Comets, including Comet 1s operated by BOAC and Union Aeromaritime de Transport and Comet 4s flown by Aerolneas Argentinas, Dan-Air, Malaysian Airlines and United Arab Airlines, were irreparably damaged during takeoff or landing accidents that were survived by all on board. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes.) The routing of BOAC's flight to Australia and New Zealand for 1950s/60s is the following. [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. [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. The wing was drastically redesigned from a 40 sweep. [51], When several of the fuselage alloys were discovered to be vulnerable to weakening via metal fatigue, a detailed routine inspection process was introduced. With a clientele composed mainly of wealthy people, luxury was the name of the game for these flights. The Comet Story. BCPA had actually ordered three Comet 2s from de Havilland, although the agreement had never been fully finalised. [88], On 19 October 1954, the Cohen Committee was established to examine the causes of the Comet crashes. Some amazing Britannia footage, Stratocruisers & DC-7Cs too! [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 airline eventually became British Airways through a merger and continues flying the Boeing 747 between London and several U.S.. 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. 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. [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. Soon after, the de Havilland Comet became the first commercial jetliner, and it set Great Britain up to be one of the most influential nations in the development of commercial aviation. [61] Comet 1s subsequently received more powerful 5,700lbf (25kN) Ghost DGT3 series engines. [72], Prince Philip returned from the Helsinki Olympic Games with G-ALYS on 4 August 1952. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. 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. As a young woman, Thorne . 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. [177], The original operators of the early Comet 1 and the Comet 1A were BOAC, Union Aromaritime de Transport and Air France. The low-mounted engines and good placement of service panels also made aircraft maintenance easier to perform. The first flight of Concorde 001 from Toulouse, France took place and was shortly followed by Concorde 002 from Filton . [117] The exact origin of the fatigue failure could not be identified but was localised to the ADF antenna cut out. [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. 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. On the Eastern route there was a 22% increase in traffic but on the Southern route only a 2% increase." 2 December: The inaugural flight of a BOAC Comet 4 aircraft on the London to Johannesburg route took place. [53][54], The Comet was powered by two pairs of turbojet engines buried in the wings close to the fuselage. [116] Based on these findings, Comet 1 structural failures could be expected at anywhere from 1,000 to 9,000 cycles. [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. [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. All but four Comet 2s were allocated to the RAF, deliveries beginning in 1955. Explore our past: 1969. [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. A year later, the second prototype G-5-2 made its maiden flight. Was: $999.99 57% off. The aircraft plunged into a dry drainage canal and collided with an embankment, killing all five crew and six passengers on board. On whether we grasp this opportunity and so establish firmly an industry of the utmost strategic and economic importance, our future as a great nation may depend. [165] Although these aircraft performed well on test flights on the South Atlantic, their range was still not suitable for the North Atlantic. [76] Popular Mechanics wrote that Britain had a lead of three to five years on the rest of the world in jetliners. 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. Crashed near Elba 10/1/54. 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. In 1962, BOAC and the British steamship company Cunard formed BOAC-Cunard Ltd, operating services to North America, the Caribbean and South America. [191][192] In 2012, with the planned closure of RAF Lyneham, the aircraft was slated to be dismantled and shipped to the RAF Museum Cosford where it was to be re-assembled for display. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. BOAC took delivery of 10 Comets and the first passenger service opened to Johannesburg on 2 May 1952. G-APDM Comet 4. Design and construction flaws, including improper riveting and dangerous concentrations of stress around some of the square windows, were ultimately identified. [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. The Monarch Service is the name BOAC used for the on board experience on routes across the Atlantic. ", "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. 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. [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. 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. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. "De Havilland DH.106 Comet. [140] Olympic Airways was the only other customer to order the type. 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. [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. [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. USA et International; Australie; Canada; France; Allemagne; Italie; Espagne; Royaume-Uni; Qui sommes-nous; Although sales never fully recovered, the improved Comet2 and the prototype Comet3 culminated in the redesigned Comet4 series which debuted in 1958 and remained in commercial service until 1981. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. 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. [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. [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952. The Comet was withdrawn from service and extensively tested. [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. ", "De Havilland DH.106 Comet 4, G-APDJ, Air Ceylon. [98][99] With no witnesses to the disaster and only partial radio transmissions as incomplete evidence, no obvious reason for the crash could be deduced. [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. At about 10:51 GMT, the aircraft suffered an explosive decompression at . Most commonly quoted are the 'square' passenger windows. [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. [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. ", Duncan Sandys, Minister of Supply, 1952. The Comet gave BOAC four years lead in modern jet airliners over the rest of the world. The VC10s on these Nigeria Airways timetables mostly referred to BOAC VC10s that were flown with Nigeria Airways stickers. [162] Design changes had been made to make the aircraft more suitable for transatlantic operations. [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 Comet 4 was a further improvement on the stretched Comet 3 with even greater fuel capacity. [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). 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. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. 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. Hill, Malcolm L. "de Havilland's Comet: Pushing the Boundaries.". BOAC installed 36 reclining "slumberseats" with 45in (1,100mm) centres on its first Comets, allowing for greater leg room in front and behind;[30] Air France had 11 rows of seats with four seats to a row installed on its Comets. First production Comet for BOAC. [20] One window frame survived 100psi (690kPa),[21] about 1,250 percent over the maximum pressure it was expected to encounter in service. First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. [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. [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. 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. British South American Airways merged with BOAC in 1949. [75], In 1953, the Comet appeared to have achieved success for de Havilland. [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. For the first time ever, a jet-propelled aircraft was carrying. The De Havilland Comet was used on BOAC's transatlantic crossing Credit: Getty I t all started with a newspaper. The exception was G-ARVC that spent a year in full Nigeria Airways livery, during 1966. G-ALYP Author. [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. [83] Financial problems and a takeover by United Airlines meant that Capital would never operate the Comet. 546 or 746 of which the skin was made and in accordance with the advice I received from my Assessors, I accept the conclusion of RAE that this is a sufficient explanation of the failure of the cabin skin of Yoke Uncle by fatigue after a small number, namely, 3,060 cycles of pressurisation.". The return flight to London took place three days later, on May 5, 1952. [13] Sprite fittings were retained on production aircraft.
