boac comet routes

[171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. [4] One of its recommendations was for the development and production of a pressurised, transatlantic mailplane that could carry 1 long ton (2,200lb; 1,000kg) of payload at a cruising speed of 400mph (640km/h) non-stop. [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. All outstanding orders for the Comet 2 were cancelled by airline customers.

Smith, Adrian. [93], After the loss of G-ALYV, the Government of India convened a court of inquiry[92] to examine the cause of the accident. Specialised signals intelligence and electronic surveillance capability was later added to some airframes. Green, William and Gordon Swanborough, eds. 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. Flights commenced on 4 October 1958 with the de Havilland Comet 4, bringing jet travel to the crossing for the first time . 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 . Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. [34][N 11] For passengers used to propeller-driven airliners, smooth and quiet jet flight was a novel experience. 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 . Nigeria Airways timetable August 1965 - page 1 Was: $999.99 57% off. [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. The next was at Karachi on 2 March 1953 when a Canadian Pacific Airlines Comet, on its delivery flight to Sydney, had a similar crash killing all on board, including some Australians. Before the Elba accident, G-ALYP had made 1,290 pressurised flights, while G-ALYY had made 900 pressurised flights before crashing. The Feb 1959 OAG shows eight transatlantic Comets a week out of London, plus 10 BOAC Britannias and 11 DC-7Cs. These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. 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. The other Comet 3 airframe was not completed to production standard and was used primarily for ground-based structural and technology testing during development of the similarly sized Comet 4. [10][153] The Comet's buried engines were used on some other early jet airliners, such as the Tupolev Tu-104,[154] but later aircraft, such as the Boeing 707 and Douglas DC-8, differed by employing podded engines held on pylons beneath the wings. Most commonly quoted are the 'square' passenger windows. 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. [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. SA on 22 nd January 1952. In April 1960, 13 Comets, 19 Britannias and 6 DC-7Cs. ", "Commercial Aircraft 1953: De Havilland Comet. First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. [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. 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. 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. [124] Paul Withey, Professor of Casting at the University of Birmingham School of Metallurgy states in a video presentation delivered in 2019, analysing all available data that: "The fact that DeHavilland put oval windows into later marks, is not because of any 'squareness' of the windows that caused failure. Both of these aeroplanes would continue to operate side by side until the formation of British Airways PLC in 1974. [32] Amenities included a galley that could serve hot and cold food and drinks, a bar, and separate men's and women's toilets. [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. [107][108] The forensic reconstruction effort had just begun when the Abell Committee reported its findings. BCPA had actually ordered three Comet 2s from de Havilland, although the agreement had never been fully finalised. [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. This artificial feel was the first of its kind to be introduced in any aircraft. 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. No apparent fault in the aircraft was found,[N 19] and the British government decided against opening a further public inquiry into the accident. When retired in 1973, the airframe was used for foam-arrester trials before the fuselage was salvaged at BAE Woodford, to serve as the mock-up for the Nimrod.[172]. [115] A further test reproduced the same results. BOAC Comet 4 Captains Folder Africa routes original 1960s document Comet 4[edit] 304755204133. [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). 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. Institution of Electrical Engineers 1978, p. 89. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. [N 22][163] A total of 12 of the 44-seat Comet 2s were ordered by BOAC for the South Atlantic route. The. Worldwide International 134457089011 [27] The Ghost engines allowed the Comet to fly above weather that competitors had to fly through. The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. 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. Davies and Birtles 1999, p. 22 (Route map illustration). In later years we realised that these were the indications of how flimsy the structure really was. [52], Operationally, the design of the cargo holds led to considerable difficulty for the ground crew, especially baggage handlers at the airports. 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. The operation was short-lived and was dissolved in 1966. 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. Its introduction into BOAC service in May 1952, was greeted as the dawning of a new age in passenger travel. [N 16] Professor Natesan Srinivasan joined the inquiry as the main technical expert. "A BOAC de Havilland Comet jet airliner, en route to Johannesburg from London, breaks its journey at Entebbe Airport, Uganda, 1952." (Ministry of Information official photographer) The de Havilland Comet was the first commercial jet airliner and its introduction had revolutionized the industry. [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. BOAC SOUTH PACIFIC Route Airline Menu Ny -San Francisco-Honolulu-Nandi-Sydney - $38.98. [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. The Ministry of Supply's order for DH 108s was listed as Operational Requirement OR207 to Specification E.18/45. [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. 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. Registered 18/09/1951 to de Havilland Aircraft Company. BOAC ordered 19 Comet 4s in March 1955, and American operator Capital Airlines ordered 14 Comets in July 1956. The American jets were larger, faster, longer-ranged and more cost-effective than the Comet. [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.
