[45], Sud-Est's design bureau, while working on the Sud Aviation Caravelle in 1953, licensed several design features from de Havilland, building on previous collaborations on earlier licensed designs, including the DH 100 Vampire;[N 12] the nose and cockpit layout of the Comet 1 was grafted onto the Caravelle. 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. [177], The original operators of the early Comet 1 and the Comet 1A were BOAC, Union Aromaritime de Transport and Air France. "The Dawn of the Jet Age in Austerity Britain: David Lean's The Sound Barrier". [N 15] In summer 1953, eight BOAC Comets left London each week: three to Johannesburg, two to Tokyo, two to Singapore and one to Colombo. [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. In September 1972 the airlines of BOAC and BEA began a merger, eventually forming British Airways on 31 March 1974. 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. 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. [31] Large picture window views and table seating accommodations for a row of passengers afforded a feeling of comfort and luxury unusual for transportation of the period. G-ALYP a/f 6003.

", Withuhn, Bill. Avon-powered Comets were distinguished by larger air intakes and curved tailpipes that reduced the thermal effect on the rear fuselage. [176] The final Nimrod aircraft were retired in June 2011. Green, William and Gordon Swanborough, eds. BOAC installed 36 reclining "slumberseats" with 45in (1,100mm) centres on its first Comets, allowing for greater leg room in front and behind;[30] Air France had 11 rows of seats with four seats to a row installed on its Comets. Nigeria Airways timetable August 1965 - page 1 A de Havilland DH-106 Comet 1 passenger plane, operated by BOAC, was destroyed in an accident near Calcutta, India. The inaugural flight was filmed, and a video and transcript is below: Now in great ships of the sky, British captains and their crews wing their way half around the world to Australia in 33 hours, almost 13,000 miles. Find many great new & used options and get the best deals for BOAC REVIEW AIRLINE STAFF MAGAZINE SEPTEMBER 1965 B.O.A.C. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. BOAC went on to fly the 707 on its own trans-Atlantic flights. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. [145], In the 1960s, orders declined, a total of 76 Comet 4s being delivered from 1958 to 1964. [24], The prototype was registered G-ALVG just before it was publicly displayed at the 1949 Farnborough Airshow before the start of flight trials. [66] On 22 January 1952, the fifth production aircraft, registered G-ALYS, received the first Certificate of Airworthiness awarded to a Comet, six months ahead of schedule. A number of other pressurised airliners of the period including the Boeing 377 Stratocruiser, Douglas DC-7, and DC-8 had larger more 'square' windows than the Comet 1 and experienced no such failures. 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. [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)) [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. [82] Three fatal Comet 1 crashes due to structural problems, specifically BOAC Flight 783 on 2 May 1953, BOAC Flight 781 on 10 January 1954 and South African Airways Flight 201 on 8 April 1954, led to the grounding of the entire Comet fleet. 106 Comet.". [9] Several unorthodox configurations were considered, ranging from canard to tailless designs;[N 4] All were rejected. [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. [151][152], Aeronautical-engineering firms were quick to respond to the Comet's commercial advantages and technical flaws alike; other aircraft manufacturers learned from, and profited by, the hard-earned lessons embodied by de Havilland's Comet. In April 1960, 13 Comets, 19 Britannias and 6 DC-7Cs. [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. FOR SALE! Comet Lost: Services Suspended. All airline customers for the Comet 3 subsequently cancelled their orders and switched to the Comet 4,[63] which was based on the Comet 3 but with improved fuel capacity. Super VC10 G-ASGE seen in the BOAC/Cunard colours during the period that the airline and shipping line co-operated on UK-USA routes. [194] A Comet 4B (G-APYD) is stored in a facility at the Science Museum at Wroughton in Wiltshire, England. [citation needed], The Comet 4 first flew on 27 April 1958 and received its Certificate of Airworthiness on 24 September 1958; the first was delivered to BOAC the next day. Another clue is in the BA flight numbers in the schedules. [13] Sprite fittings were retained on production aircraft. [147] The Bruntingthorpe Aerodrome also displays a related Hawker Siddeley Nimrod MR2 aircraft. The low-mounted engines and good placement of service panels also made aircraft maintenance easier to perform. 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. Worldwide International 134457089011 546 or 746 of which the skin was made and in accordance with the advice I received from my Assessors, I accept the conclusion of RAE that this is a sufficient explanation of the failure of the cabin skin of Yoke Uncle by fatigue after a small number, namely, 3,060 cycles of pressurisation.". 2 March. Courtesy British Airways. The committee concluded that fire was the most likely cause of the problem, and changes were made to the aircraft to protect the engines and wings from damage that might lead to another fire. [15] The Comet 4 was considered the definitive series, having a longer range, higher cruising speed and higher maximum takeoff weight. [5] Out of all the Brabazon designs, the DH.106 was seen as the riskiest: both in terms of introducing untried design elements and for the financial commitment involved. [15] Replacing previously specified Halford H.1 Goblin engines, four new, more-powerful Rolls-Royce Avons were to be incorporated in pairs buried in the wing roots; Halford H.2 Ghost engines were eventually applied as an interim solution while the Avons cleared certification. 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. On the flight, he was accompanied by Chris Beaumont, Chief Test Pilot of the DeHavilland Engine Company (that made the Comet 1's Ghost engines) who stood in the entrance to the cockpit behind the Flight Engineer. As a young woman, Thorne . [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. Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. "[174], The Comet 5 was proposed as an improvement over previous models, including a wider fuselage with five-abreast seating, a wing with greater sweep and podded Rolls-Royce Conway engines. [114] The fuselage frames did not have sufficient strength to prevent the crack from propagating. Trischler, Helmuth and Stefan Zeilinger, eds. [18] The prototype's maiden flight, out of Hatfield Aerodrome, took place on 27 July 1949 and lasted 31 minutes. 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 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. [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. "[127], The Cohen inquiry closed on 24 November 1954, having "found that the basic design of the Comet was sound",[111] and made no observations or recommendations regarding the shape of the windows. [28], One of the most striking aspects of Comet travel was the quiet, "vibration-free flying" as touted by BOAC. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. Though these lessons could be implemented on the drawing board for future aircraft, corrections could only be retroactively applied to the Comet. : This photo of Super VC10 G-ASGD taken in Mexico in 1972 shows the Speedbird livery without Cunard titles. The five-stop flight from London to Johannesburg was scheduled for 21 hr 20 min. Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952. The second prototype was registered G-ALZK in July 1950 and it was used by the BOAC Comet Unit at Hurn from April 1951 to carry out 500 flying hours of crew training and route-proving. 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.
