1945 November: The government announced plans for post-war air services which would be provided by three state corporations: BOAC to continue to operate routes to the Empire, Far East and North America, British European Airways ( BEA) to operate services to Europe and domestically within the United Kingdom, and British South American Airways ", "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. Be sure to check my channel for the best in VINTAGE & RARE airliner videos! 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. The operation was short-lived and was dissolved in 1966. "[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. [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.

BOAC SOUTH PACIFIC Route Airline Menu Ny -San Francisco-Honolulu-Nandi-Sydney - $38.98. [170] Only two Comet 3s began construction; G-ANLO, the only airworthy Comet 3, was demonstrated at the Farnborough SBAC Show in September 1954. On 10 January 1954, British Overseas Airways Corporation Flight 781 a de Havilland DH.106 Comet 1 registered G-ALYP, 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. The Imperial War Museum Duxford has a Comet 4 (G-APDB), originally in Dan-Air colours as part of its Flight Line Display, and later in BOAC livery at its AirSpace building. [17] The majority of hydraulic components were centred in a single avionics bay. [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. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. [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. [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. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. [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. canuck DC-8. 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. [72], Prince Philip returned from the Helsinki Olympic Games with G-ALYS on 4 August 1952. ", "De Havilland Comet 4B airliner, serial no 6438, 1960. The. Depending on weight and temperature, cruise fuel consumption was 6 to 10kg (13 to 22lb) per nautical mile (1.2 miles; 1.9 km), the higher figure being at the lower altitude needed at high weight. [189] Though painted in BOAC colours, it never flew for the airline, having been first delivered to Air France and then to the Ministry of Supply after conversion to 1XB standard;[189] this aircraft also served with the RAF as XM823. Nigeria Airways timetable August 1965 - page 1 [14], As the Comet represented a new category of passenger aircraft, more rigorous testing was a development priority. [173] A Comet 4C (SA-R-7) was ordered by Saudi Arabian Airlines with an eventual disposition to the Saudi Royal Flight for the exclusive use of King Saud bin Abdul Aziz. On the Eastern route there was a 22% increase in traffic but on the Southern route only a 2% increase." Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. 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. [115] A further test reproduced the same results. 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 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. Engineers at de Havilland immediately recommended 60 modifications aimed at any possible design flaw, while the Abell Committee met to determine potential causes of the crash. "[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." [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. Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. The Comet gave BOAC four years lead in modern jet airliners over the rest of the world. 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.

For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. [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. Witnesses observed the wingless Comet on fire plunging into the village of Jagalgori,[92] leading investigators to suspect structural failure. [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. ST-AAX Comet 4C. [176] The final Nimrod aircraft were retired in June 2011. On 22 nd September this BOAC Comet was flown from Stansted to London Airport. Atkinson, R. J., W. J. Winkworth and G. M. Norris. Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. The World's First Jet Airliner" U.K. They ran smoothly and were less noisy than piston engines, had low maintenance costs and were fuel-efficient above 30,000ft (9,100m). [105] The first pieces of wreckage were discovered on 12 February 1954[106] and the search continued until September 1954, by which time 70 percent by weight of the main structure, 80 percent of the power section, and 50 percent of the aircraft's systems and equipment had been recovered. 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. The exception was G-ARVC that spent a year in full Nigeria Airways livery, during 1966. 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. [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. [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952. De Havilland nonetheless began a refit programme to strengthen the fuselage and wing structure, employing thicker-gauge skin and replacing the rectangular windows and panels with rounded versions, although this was not related to the erroneous 'square' window claim, as can be seen by the fact that the fuselage escape hatch cut-outs (the source of the failure in test aircraft G-ALYU) retained their rectangular shape. 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. 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. Photo: Getty Images This simply meant that the planes landed on solid ground at airports rather than water. 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. The COMET 4 remained in BOAC trans-Atlantic service though as new north American destinations . Queen Elizabeth, the Queen Mother and Princess Margaret were guests on a special flight of the Comet on 30 June 1953 hosted by Sir Geoffrey and Lady de Havilland. 2 March. ", "ASN Aircraft accident de Havilland DH-106 Comet 4 G-APDN Sierra del Montseny", "de Havilland DH106 Comet 1A de Havilland Aircraft Museum", "Gate Guardian Comet C2 Sagittarius XK699 RAF Lyneham. [31][60] These were tested on 30 flights, but the Ghosts alone were considered powerful enough and some airlines concluded that rocket motors were impractical. [12] The DH 108s were later modified to test the DH.106's power controls. [15] The Comet 4 was considered the definitive series, having a longer range, higher cruising speed and higher maximum takeoff weight. New opportunities Explore our past: 1969. Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. [147] The Bruntingthorpe Aerodrome also displays a related Hawker Siddeley Nimrod MR2 aircraft. 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. [86][87] The accident was the first fatal jetliner crash. [177], The original operators of the early Comet 1 and the Comet 1A were BOAC, Union Aromaritime de Transport and Air France. During a radio communication about weather conditions, the conversation was abruptly cut off. [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. [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. ", "On This Day: Comet inaugurates the jet age.". The route was London, Frankfurt, Beirut, Karachi, Delhi, Calcutta, Bangkok, Hong Kong, Tokyo. 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. Avon-powered Comets were distinguished by larger air intakes and curved tailpipes that reduced the thermal effect on the rear fuselage. 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 . 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. 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. [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. [162] Design changes had been made to make the aircraft more suitable for transatlantic operations. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. In September 1972 the airlines of BOAC and BEA began a merger, eventually forming British Airways on 31 March 1974. [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.
