[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. [93], After the loss of G-ALYV, the Government of India convened a court of inquiry[92] to examine the cause of the accident. 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. The most extensive modification resulted in a specialised maritime patrol derivative, the Hawker Siddeley Nimrod, which remained in service with the Royal Air Force until 2011, over 60 years after the Comet's first flight. [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. VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. 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. 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. [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. Hall: "In the light of known properties of the aluminium alloy D.T.D. The individual pieces of luggage and cargo also had to be retrieved in a similarly slow manner at the arriving airport. Though these lessons could be implemented on the drawing board for future aircraft, corrections could only be retroactively applied to the Comet. ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. [141] The last Comet 4 variant, the Comet 4C, first flew on 31 October 1959 and entered service with Mexicana in 1960. BOAC started the first regular round-the-world service by Britannia 312 aircraft, operating via San Francisco and Hong Kong. They were bound for Idlewild via a stop at Gander, Newfoundland, which would be commonplace on eastbound flights. 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. He stated "Every time we pulled 2 1/2-3G to go around the corner, Chris found that the floor on which he was standing, bulging up and there was a loud bang at that speed from the nose of the aircraft where the skin 'panted' (flexed), so when we heard this bang we knew without checking the airspeed indicator, that we were doing 340 knots. After design modifications were implemented, Comet services resumed on October 4, 1958 with Comet 4s. [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. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes.) [86][87] The accident was the first fatal jetliner crash. [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. [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. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. In later years we realised that these were the indications of how flimsy the structure really was. The airplane operated on a return flight from London, UK to Singapore. The Johannesburg-bound Comet, designated G-ALYP by BOAC, flew at 450-500 mph at 35-40,000 feet, covering 6,700 miles in 23 hours and 20 minutes, with stops in Rome, Beirut, Khartoum, Entebbe, and Livingstone. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . [43] A pressurised refuelling system, developed by Flight Refuelling Ltd, allowed the Comet's fuel tanks to be refuelled at a far greater rate than by other methods. With a clientele composed mainly of wealthy people, luxury was the name of the game for these flights. [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.

[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. [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952. All outstanding orders for the Comet 2 were cancelled by airline customers. 1 January. However, the route was suspended in October 1943, and a UK-Cairo-Karachi service was launched. "Preludes and Overtures: de Havilland Comet 1". 10 January 1954: BOAC jet crashes off the Mediterranean island of Elba killing 35 people on board 8 April 1954: South African Airways Comet crashes en route from Rome to Johannesburg - all 14. The trip took 33 hours. FR. [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). Also in that year the Comet route to New York was extended to Nassau and Montego Bay. [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. or Best Offer. On 4 October . These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. Photo: Getty Images ", 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. 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. The Comet 4 was a further improvement on the stretched Comet 3 with even greater fuel capacity. 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.

[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. 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. [82], Since retirement, three early-generation Comet airframes have survived in museum collections. [82][143], In 1959 BOAC began shifting its Comets from transatlantic routes[N 21] and released the Comet to associate companies, making the Comet 4's ascendancy as a premier airliner brief. Be sure to check my channel for the best in VINTAGE & RARE airliner videos! [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. [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. The American jets were larger, faster, longer-ranged and more cost-effective than the Comet. [176] The final Nimrod aircraft were retired in June 2011. 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 De Havilland Aircraft Company DH106 Comet was the World's first pressurised commercial jet airliner and it was the source of enormous national pride. 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. In 1962, BOAC and the British steamship company Cunard formed BOAC-Cunard Ltd, operating services to North America, the Caribbean and South America. The aircraft featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurized cabin, and large square windows. [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 16] Professor Natesan Srinivasan joined the inquiry as the main technical expert. [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. The return flight to London took place three days later, on May 5, 1952. [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. BOADICEA COMPUTER SYS at the best online prices at eBay! Nigeria Airways timetable August 1965 - page 1 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. Without support from the Ministry of Transport, the proposal languished as a hypothetical aircraft and was never realised. [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. ", "DH106 Comet 'Canopus' 'Fast Taxi Run' - Bruntingthorpe Cold War Jets (May 2018)", "Comet 4C: More Payload on Medium Stages. [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. [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. Hill, Malcolm L. "de Havilland's Comet: Pushing the Boundaries.". [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). It was later determined that the Comet's wing profile experienced a loss of lift at a high angle of attack, and its engine inlets also suffered a lack of pressure recovery in the same conditions. [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. 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. FOR SALE! As a result, the Comet was extensively redesigned, with oval windows, structural reinforcements and other changes. ", Withuhn, Bill. 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. [29][59] Two hydrogen peroxide-powered de Havilland Sprite booster rockets were originally intended to be installed to boost takeoff under hot and high altitude conditions from airports such as Khartoum and Nairobi. The operation was short-lived and was dissolved in 1966. [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. Vintage BOAC Airlines travel . LONDON, Jan. 2 (ReutersSir Giles Guthrie, new c hairman of the publicIy owned British Overseas Airways Corporation has ordered a review of the . 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. [82][178][181] BEA's Comet 4Bs were chartered by Cyprus Airways, Malta Airways and Transportes Areos Portugueses. Explore our past: 1969. 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.
