[170] Only two Comet 3s began construction; G-ANLO, the only airworthy Comet 3, was demonstrated at the Farnborough SBAC Show in September 1954. Two passengers sustained minor injuries, but the aircraft, G-ALYZ, was a write-off. [111][185] The Royal Canadian Air Force also operated Comet 1As (later retrofitted to 1XB) through its 412 Squadron from 1953 to 1963. BEA's Super One-Eleven aircraft enter scheduled service on German internal routes. The VC10s on these Nigeria Airways timetables mostly referred to BOAC VC10s that were flown with Nigeria Airways stickers. BOAC chmn Guthrie orders rev of co's routes. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. The return flight to London took place three days later, on May 5, 1952. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. 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. [110] The Comet's Certificate of Airworthiness was revoked, and Comet 1 line production was suspended at the Hatfield factory while the BOAC fleet was permanently grounded, cocooned and stored. ", Tony Fairbrother, manager, upgraded Comet development. [83][84] Qantas was interested in the Comet 1 but concluded that a version with more range and better takeoff performance was needed for the London to Canberra route. BOAC said, "the Comet 4 was largely responsible for the fact that between April 1 st and September 19 th traffic was up by 40% on the North Atlantic compared to the summer period of 1958. Singapore arrival mark on back. A BOAC Comet 1 at London Airport in 1955. At about 10:51 GMT, the aircraft suffered an explosive decompression at . BOAC Flight 781. [97] Aviation author Bill Withuhn concluded that the Comet had pushed "'the state-of-the-art' beyond its limits. A de Havilland DH-106 Comet 1 passenger plane, operated by BOAC, was destroyed in an accident near Calcutta, India. [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. 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. Just before the 747s came along and bumped the 707s onto other services. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes). [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. [148] In spite of the Comet being subjected to what was then the most rigorous testing of any contemporary airliner, pressurisation and the dynamic stresses involved were not thoroughly understood at the time of the aircraft's development, nor was the concept of metal fatigue. ST-AAX Comet 4C. The first Comet 4B flew on 27 June 1959 and BEA began Tel Aviv to London-Heathrow services on 1 April 1960. USA et International; Australie; Canada; France; Allemagne; Italie; Espagne; Royaume-Uni; Qui sommes-nous; They ran smoothly and were less noisy than piston engines, had low maintenance costs and were fuel-efficient above 30,000ft (9,100m). [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. 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. [194] A Comet 4B (G-APYD) is stored in a facility at the Science Museum at Wroughton in Wiltshire, England. On 22 nd September this BOAC Comet was flown from Stansted to London Airport. [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. 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. [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. 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. Most commonly quoted are the 'square' passenger windows. "Database: D.H. 106 Comet". In May 1952 BOAC became the first airline in the world to fly passenger jets with the de Havilland Comet which initially flew via Nairobi to Johannesburg and via the Far East to Tokyo. As a result, the Comet was extensively redesigned, with oval windows, structural reinforcements and other changes. : This photo of Super VC10 G-ASGD taken in Mexico in 1972 shows the Speedbird livery without Cunard titles. [176] The final Nimrod aircraft were retired in June 2011. Find many great new & used options and get the best deals for BOAC REVIEW AIRLINE STAFF MAGAZINE SEPTEMBER 1965 B.O.A.C. [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. ", Duncan Sandys, Minister of Supply, 1952. The wing was drastically redesigned from a 40 sweep. Hill, Malcolm L. "de Havilland's Comet: Pushing the Boundaries.". [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. [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. The last two Comet 4C fuselages were used to build prototypes of the Hawker Siddeley Nimrod maritime patrol aircraft. [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). FOR SALE!

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. Kodera, Craig, Mike Machat and Jon Proctor. [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. BOAC took delivery of 10 Comets and the first passenger service opened to Johannesburg on 2 May 1952. 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. [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. [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. As well as thorough visual inspections of the outer skin, mandatory structural sampling was routinely conducted by both civil and military Comet operators. [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. 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. [38], Several of the Comet's avionics systems were new to civil aviation. Oakey, Michael, ed. 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 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. Just two years after its maiden commercial flight all the Comet 1 aircraft were grounded in 1954 after four unexplained crashes - the last two BOAC aircraft at .

Hall, Geoffrey de Havilland and Bishop were immediately called to the scene, where the water tank was drained to reveal that the fuselage had ripped open at a bolt hole, forward of the forward left escape hatch cut out. Ordered by Kuwait Airways, Middle East Airlines, Misrair (later United Arab Airlines), and Sudan Airways, it was the most popular Comet variant. [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. G-ALYP a/f 6003. [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)) Principal investigator Hall accepted the RAE's conclusion of design and construction flaws as the likely explanation for G-ALYU's structural failure after 3,060 pressurisation cycles. BOAC flew two de Havilland Comet 4 aircraft between London and New York International Airport, Idlewild. [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. [102], In water-tank testing, engineers subjected G-ALYU to repeated repressurisation and over-pressurisation, and on 24 June 1954, after 3,057 flight cycles (1,221 actual and 1,836 simulated),[113] G-ALYU burst open. Worldwide International 134457089011 [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. [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.
