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. 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.

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. Birtles, P.J. [176] The final Nimrod aircraft were retired in June 2011. [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. Also in that year the Comet route to New York was extended to Nassau and Montego Bay. This was short lived as later that year Britannias took over that route. [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. First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. [27] The Ghost engines allowed the Comet to fly above weather that competitors had to fly through. 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. Design and construction flaws, including improper riveting and dangerous concentrations of stress around some of the square windows, were ultimately identified. "The de Havilland Comet Srs. [146] On 14 March 1997 a Comet 4C serial XS235 and named Canopus,[147] which had been acquired by the British Ministry of Technology and used for radio, radar and avionics trials, made the last documented production Comet flight. 1961: West express A new Qantas route from London to Perth has refuelling stops in Tehran, Karachi,. [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. [32] Amenities included a galley that could serve hot and cold food and drinks, a bar, and separate men's and women's toilets. ", Prime Minister Winston Churchill, 1954. The Feb 1959 OAG shows eight transatlantic Comets a week out of London, plus 10 BOAC Britannias and 11 DC-7Cs. 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. 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. Green and Swanborough April 1977, p. 174. ", "Commercial Aircraft 1953: De Havilland Comet. The flight to Johannesburg lasted 18 hours and 40 minutes. The Comet was also adapted for a variety of military roles such as VIP, medical and passenger transport, as well as surveillance; the last Comet 4, used as a research platform, made its final flight in 1997. ", "De Havilland DH.106 Comet 4, G-APDJ, Air Ceylon. (Cohen Inquiry accident report Fig 7). [75], In 1953, the Comet appeared to have achieved success for de Havilland. Both of these aeroplanes would continue to operate side by side until the formation of British Airways PLC in 1974. For VIP transport, the seating and accommodations were altered and provisions for carrying medical equipment including iron lungs were incorporated. Menu. [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. The COMET 4 remained in BOAC trans-Atlantic service though as new north American destinations . [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. Last edited on 23 February 2023, at 18:58, Netaji Subhash Chandra Bose International Airport, "Comet Engineering: The Performance of Airframe, Engines, and Equipment in Operational Service. Find many great new & used options and get the best deals for BOAC REVIEW AIRLINE STAFF MAGAZINE SEPTEMBER 1965 B.O.A.C. [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. [184], In military service, the United Kingdom's Royal Air Force was the largest operator, with 51 Squadron (19581975; Comet C2, 2R), 192 Squadron (19571958; Comet C2, 2R), 216 Squadron (19561975; Comet C2 and C4), and the Royal Aircraft Establishment using the aircraft. [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. [107][108] The forensic reconstruction effort had just begun when the Abell Committee reported its findings. The type and design were to be so advanced that de Havilland had to undertake the design and development of both the airframe and the engines. [44], The cockpit was significantly altered for the Comet 4's introduction, on which an improved layout focusing on the onboard navigational suite was introduced. The number one route was still the famous 'Kangaroo Route', which since 1947 was operated in a profit-sharing partnership with BOAC, but the airline also had routes to Hong Kong, Japan and South Africa plus now BCPA's network too. A de Havilland DH-106 Comet 1 passenger plane, operated by BOAC, was destroyed in an accident near Calcutta, India. Crews on this route were given military status due to the operations in military regions. However, no mail was flown to or from Frankfurt on the outward flight. 1 November: The inaugural flight of a BOAC De Havilland Comet 4 aircraft on the London to Sydney route took place. Before the Elba accident, G-ALYP had made 1,290 pressurised flights, while G-ALYY had made 900 pressurised flights before crashing. ", GB-High Wycombe: "Dismantlement and relocation of Gate Guardian Comet C2 XK699. [88], On 19 October 1954, the Cohen Committee was established to examine the causes of the Comet crashes. This artificial feel was the first of its kind to be introduced in any aircraft. [97][N 17], Just over a year later, Rome's Ciampino airport, the site of the first Comet hull loss, was the origin of a more-disastrous Comet flight. For the first time ever, a jet-propelled aircraft was carrying. Comet Lost: Services Suspended. 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. [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. At the end of the month this Comet was brought back to Hatfield from Cambridge (Marshall's) where 'radio' mods were made (JH).

Photo: Getty Images On the Eastern route there was a 22% increase in traffic but on the Southern route only a 2% increase." The de Havilland Comet 4 aircraft reduced the flight time between London and New York to seven hours - significantly less than the 18-20 hours it took on the Boeing Stratocruiser 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. "[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. The Comet Story. [34][N 11] For passengers used to propeller-driven airliners, smooth and quiet jet flight was a novel experience. On 22 nd September this BOAC Comet was flown from Stansted to London Airport. On the 10 th December R. Clear commanded test flights from Hatfield. ", "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 (d). In command was Capt Tom Stoney, manager of BOAC's Comet Flight. BOAC de Havilland Comet 1 Jet Airliner Colour Card FB12P: $4.86.

Ordered by Kuwait Airways, Middle East Airlines, Misrair (later United Arab Airlines), and Sudan Airways, it was the most popular Comet variant. All 43 on board were killed. Institution of Electrical Engineers 1978, p. 89. [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. Specialised signals intelligence and electronic surveillance capability was later added to some airframes. [114] The fuselage frames did not have sufficient strength to prevent the crack from propagating. Investigators did not consider metal fatigue as a contributory cause. 1969. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. G-ALYP a/f 6003. Kodera, Craig, Mike Machat and Jon Proctor. Herman. [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. [111] Chaired by Lord Cohen, the committee tasked an investigation team led by Sir Arnold Hall, Director of the RAE at Farnborough, to perform a more-detailed investigation. In later years we realised that these were the indications of how flimsy the structure really was. [49] The Comet's high cabin pressure and fast operating speeds were unprecedented in commercial aviation, making its fuselage design an experimental process.
