Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. The route was London, Frankfurt, Beirut, Karachi, Delhi, Calcutta, Bangkok, Hong Kong, Tokyo. Hall's team began considering fatigue as the most likely cause of both accidents and initiated further research into measurable strain on the aircraft's skin. [43] A pressurised refuelling system, developed by Flight Refuelling Ltd, allowed the Comet's fuel tanks to be refuelled at a far greater rate than by other methods. 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. [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. The need to inspect areas not easily viewable by the naked eye led to the introduction of widespread radiography examination in aviation; this also had the advantage of detecting cracks and flaws too small to be seen otherwise. BOAC went on to fly the 707 on its own trans-Atlantic flights. [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. [24], The prototype was registered G-ALVG just before it was publicly displayed at the 1949 Farnborough Airshow before the start of flight trials. [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)) Free shipping. [82] In response, Canadian Pacific cancelled its remaining order for a second Comet 1A and never operated the type in commercial service. [51], When several of the fuselage alloys were discovered to be vulnerable to weakening via metal fatigue, a detailed routine inspection process was introduced. [26] Both prototypes could be externally distinguished from later Comets by the large single-wheeled main landing gear, which was replaced on production models starting with G-ALYP by four-wheeled bogies. Delivered to British Overseas Airways Corporation (B.O.A.C.) ", This page was last edited on 23 February 2023, at 18:58. Flights commenced on 4 October 1958 with the de Havilland Comet 4, bringing jet travel to the crossing for the first time . Trischler, Helmuth and Stefan Zeilinger, eds. 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.". ", "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). At about 10:00 GMT, the aircraft suffered an explosive decompression . The flight to Johannesburg lasted 18 hours and 40 minutes. The Approximate London, Frankfurt, Rome, Athens, Cairo, Khartoum, Entebbe, Nairobi, Livingstone, Johannesburg Route Operated By BOAC DH COMET 1 Aircraft During The Early/Mid 1950's: . 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. Armour had to be placed around the engine cells to contain debris from any serious engine failures; also, placing the engines inside the wing required a more complicated wing structure. ", Duncan Sandys, Minister of Supply, 1952. Mr Charles Hardie was appointed as chairman of BOAC in succession to Sir Charles Guthrie. Find many great new & used options and get the best deals for BOAC REVIEW AIRLINE STAFF MAGAZINE SEPTEMBER 1965 B.O.A.C. [27] The Ghost engines allowed the Comet to fly above weather that competitors had to fly through. 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. 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. Prins, Franois. Pen and Sword, 2013. The airplane operated on a return flight from London, UK to Singapore. Though these lessons could be implemented on the drawing board for future aircraft, corrections could only be retroactively applied to the Comet. 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. Following its first flight, the special order Comet 4C was described as "the world's first executive jet. G-ALYR a/f 6004. (from the structure)[126]. The Comet 1 airliner roared into the air and into historyon 20,000 pounds of thrust from its four De Havilland Ghost jet engines. Brand New. 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. The Abell Committee, named after chairman C. Abell, Deputy Operations Director (Engineering) of BOAC, consisted of representatives of the Allegation Review Board (A.R.B. 106 Comet.". "De Havilland DH.106 Comet. #dehavilland #comet #dehavillandcomet #boac #route #londontotokyo #schedule #1953 #todayinhistory #unitedkingdom #uk #japan #flag . After analysing route structures for the Comet, BOAC reluctantly cast about for a successor, and in 1956 entered into an agreement with Boeing to purchase the 707. 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. 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. [177], The original operators of the early Comet 1 and the Comet 1A were BOAC, Union Aromaritime de Transport and Air France. Rival manufacturers heeded the lessons learned from the Comet when developing their own aircraft. Posts: 86 1 November: The inaugural flight of a BOAC De Havilland Comet 4 aircraft on the London to Sydney route took place. "Database: D.H. 106 Comet". BOAC chmn Guthrie orders rev of co's routes. "[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." 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 . [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. The Comet Story. [150] Cunningham likened the Comet to the later Concorde and added that he had assumed that the aircraft would change aviation, which it subsequently did. [28] The clean, low-drag design of the aircraft featured many design elements that were fairly uncommon at the time, including a swept-wing leading edge, integral wing fuel tanks, and four-wheel bogie main undercarriage units designed by de Havilland. [5][N 6] With no time to develop the technology necessary for a proposed tailless configuration, Bishop opted for a more conventional 20-degree swept-wing design[N 7] with unswept tail surfaces, married to an enlarged fuselage accommodating 36 passengers in a four-abreast arrangement with a central aisle. Another nine Comet 3 airframes were not completed and their construction was abandoned at Hatfield. The American jets were larger, faster, longer-ranged and more cost-effective than the Comet. - May 06, 1959 Operated the inaugural London (Heathrow) - Sydney (Kingsford Smith) service - November 01, 1959 Route: London - Beirut - Karachi - Singapore - Sydney This aircraft was one of six Comet 4 aircraft wet-leased by Qantas Empire Airways from 1959 to 1963 [57] The Comet's buried-engine configuration increased its structural weight and complexity. [133][134] The base price of a new Comet 4 was roughly 1.14 million (24.81 million in 2019). [116] Based on these findings, Comet 1 structural failures could be expected at anywhere from 1,000 to 9,000 cycles. FOR SALE! [82][178][181] BEA's Comet 4Bs were chartered by Cyprus Airways, Malta Airways and Transportes Areos Portugueses. [20] One window frame survived 100psi (690kPa),[21] about 1,250 percent over the maximum pressure it was expected to encounter in service. ", "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. [112] This time, the entire fuselage was tested in a dedicated water tank that was built specifically at Farnborough to accommodate its full length. [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. With a clientele composed mainly of wealthy people, luxury was the name of the game for these flights. [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. "The de Havilland Comet Srs. During a radio communication about weather conditions, the conversation was abruptly cut 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. British South American Airways merged with BOAC in 1949. Winchester, Jim, ed. [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. [168] The variant added wing pinion tanks, and offered greater capacity and range. $75.00. 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. Sections of pressurised fuselage were subjected to high-altitude flight conditions via a large decompression chamber on-site [N 10] and tested to failure. 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. [140] Deliveries to BOAC began on 30 September 1958 with two 48-seat aircraft, which were used to initiate the first scheduled transatlantic services. [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. ", "On This Day: Comet inaugurates the jet age.". The design had progressed significantly from the original Comet 1, growing by 18ft 6in (5.64m) and typically seating 74 to 81 passengers compared to the Comet 1's 36 to 44 (119 passengers could be accommodated in a special charter seating package in the later 4C series). 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. Initially used for development, training and route proving before the inaugural jet service to Jo,burg. 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]. In September 1972 the airlines of BOAC and BEA began a merger, eventually forming British Airways on 31 March 1974. BOAC Flight 781. 14.". [103], "The cost of solving the Comet mystery must be reckoned neither in money nor in manpower. Although G-APAS never flew in BOAC markings, this colour scheme is representative of the first ever fleet of passenger jet aircraft. ", "Commercial Aircraft 1953: De Havilland Comet. Menu. Simons, Graham M. "Comet! [56], Placing the engines within the wings had the advantage of a reduction in the risk of foreign object damage, which could seriously damage jet engines. BOAC's requested capacity increase was known as Specification 22/46. The Comet was withdrawn from service and extensively tested. [93] The Comet 1 and 1A had been criticised for a lack of "feel" in their controls,[95] and investigators suggested that this might have contributed to the pilot's alleged over-stressing of the aircraft;[96] Comet chief test pilot John Cunningham contended that the jetliner flew smoothly and was highly responsive in a manner consistent with other de Havilland aircraft. [58], The Comet 1 featured 5,050lbf (22.5kN) de Havilland Ghost 50 Mk1 turbojet engines. [82][143], In 1959 BOAC began shifting its Comets from transatlantic routes[N 21] and released the Comet to associate companies, making the Comet 4's ascendancy as a premier airliner brief. Sponsored. BOAC proudly served during the war. [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. [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. [197], The last Comet to fly, Comet 4C Canopus (XS235),[1] is kept in running condition at Bruntingthorpe Aerodrome, where fast taxi-runs are regularly conducted. G-ALYP Author. vs 315mph (507km/h), respectively), and a faster rate of climb further cut flight times. Mk.1. ), BOAC, and de Havilland. [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. On 10 January 1954, a de Havilland Comet passenger jet operating the flight suffered an explosive decompression at altitude and crashed, killing all 35 people on board. $430.00. Registered 18/09/1951 to de Havilland Aircraft Company. 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. The return flight to London took place three days later, on May 5, 1952.

[170] Assigned in 1961 to the Blind Landing Experimental Unit (BLEU) at RAE Bedford, the final testbed role played by GANLO was in automatic landing system experiments. "Jet Jubilee (Part 1)". On whether we grasp this opportunity and so establish firmly an industry of the utmost strategic and economic importance, our future as a great nation may depend. ", Tony Fairbrother, manager, upgraded Comet development. [N 22][163] A total of 12 of the 44-seat Comet 2s were ordered by BOAC for the South Atlantic route. Unlike drill riveting, the imperfect nature of the hole created by punch-riveting could cause fatigue cracks to start developing around the rivet. [98] The Comet fleet was immediately grounded once again and a large investigation board was formed under the direction of the Royal Aircraft Establishment (RAE). Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. The span was 115ft (35m), and overall length 93ft (28m); the maximum takeoff weight was over 105,000lb (48,000kg) and over 40 passengers could be carried. The only complete remaining Comet 1, a Comet 1XB with the registration G-APAS, the very last Comet 1 built, is displayed at the RAF Museum Cosford. [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. BOAC, British Airways' predecessor, operated the first transatlantic jet engine flight on 4 October, 1958, beating arch-rival Pan Am to become the first to do so. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. 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. [98] Prime Minister Winston Churchill tasked the Royal Navy with helping to locate and retrieve the wreckage so that the cause of the accident could be determined. [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. [82], Other operators used the Comet either through leasing arrangements or through second-hand acquisitions. Four Ghost 50 Mk 1 engines were fitted (later replaced by more powerful Ghost DGT3 series engines). (Pan Am's DC-6B was scheduled for 46 hours 45 minutes.) [40], The Comet had a total of four hydraulic systems: two primaries, one secondary, and a final emergency system for basic functions such as lowering the undercarriage. BOAC COMET 4 Captains Folder Africa routes original 1960s document - EUR 54,29. [144] In 1960, as part of a government-backed consolidation of the British aerospace industry, de Havilland itself was acquired by Hawker Siddeley, within which it became a wholly owned division. Both of these aeroplanes would continue to operate side by side until the formation of British Airways PLC in 1974. [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. 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. 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. On 10 January 1954, the flight took off at 09:34 GMT for the final-stage flight to London. For the first time ever, a jet-propelled aircraft was carrying. BOAC flight crew revelled in standing a pen on end and pointing that out to passengers; invariably, the pen remained upright throughout the entire flight. The De Havilland Comet was used on BOAC's transatlantic crossing Credit: Getty I t all started with a newspaper. Although sales never fully recovered, the improved Comet2 and the prototype Comet3 culminated in the redesigned Comet4 series which debuted in 1958 and remained in commercial service until 1981. The Johannesburg-bound Comet, designated G-ALYP by BOAC, flew at 450-500 mph at 35-40,000 feet, covering 6,700 miles in 23 hours and 20 minutes, with stops in Rome, Beirut, Khartoum, Entebbe, and Livingstone. The. [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. Surviving Comet 1s can be seen on view at the RAF Museum Cosford and the DeHavilland Museum at Salisbury Hall, London Colney. One such feature was irreversible, powered flight controls, which increased the pilot's ease of control and the safety of the aircraft by preventing aerodynamic forces from changing the directed positions and placement of the aircraft's control surfaces. "[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. Nigeria Airways timetable August 1965 - page 1 [88], On 19 October 1954, the Cohen Committee was established to examine the causes of the Comet crashes. VENDRE! 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. 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. The de Havilland DH.106 Comet was the world's first commercial jet airliner. SA on 22 nd January 1952. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. [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. (Cohen Inquiry accident report Fig 7). [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. [82], Since retirement, three early-generation Comet airframes have survived in museum collections. "[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.

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. [15] The Comet 4 was considered the definitive series, having a longer range, higher cruising speed and higher maximum takeoff weight. At the end of the month this Comet was brought back to Hatfield from Cambridge (Marshall's) where 'radio' mods were made (JH). [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. 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. The first Comet 4B flew on 27 June 1959 and BEA began Tel Aviv to London-Heathrow services on 1 April 1960. [33] Provisions for emergency situations included several life rafts stored in the wings near the engines, and individual life vests were stowed under each seat. Two passengers sustained minor injuries, but the aircraft, G-ALYZ, was a write-off. The Sud-Est SE 530/532/535 Mistral (FB 53) was a single-seat fighter-bomber version of the de Havilland Vampire jet fighter, used by. [49] The Comet's high cabin pressure and fast operating speeds were unprecedented in commercial aviation, making its fuselage design an experimental process. In later years we realised that these were the indications of how flimsy the structure really was. Range: 3,225 miles (5,190 km) Passengers: 60 to 81 On display at the Museum: The Museum's exhibit is a Comet 4 analogue flight simulator for crew training was built for BOAC by Redifon Flight Simulation at Crawley. A BOAC Comet 1 at London Airport in 1955. 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. 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. [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. BOAC then started flying Short S25 Sunderland III flying boats to West Africa. ", "De Havilland Comet 4B airliner, serial no 6438, 1960. [1], The Comet is widely regarded as both an adventurous step forward and a supreme tragedy; the aircraft's legacy includes advances in aircraft design and in accident investigations. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. [82] American carriers Capital Airlines, National Airlines, and Pan Am placed orders for the planned Comet 3, an even-larger, longer-range version for transatlantic operations. These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. The VC10s on these Nigeria Airways timetables mostly referred to BOAC VC10s that were flown with Nigeria Airways stickers. [37] The navigator occupied a dedicated station, with a table across from the flight engineer. [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. All but four Comet 2s were allocated to the RAF, deliveries beginning in 1955. AUSTRALIA 1959 BOAC Comet 4 illustrato FFC da Sydney a Singapore - EUR 3,97. At about 09:50 GMT BOAC Argonaut, G-ALHJ piloted by Captain Johnson, which was flying the same route at a lower altitude was in contact with Captain Gibson. [13] Sprite fittings were retained on production aircraft. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . Great images and Historical data of the BOAC Comet One and accompanying time period calclassic Airport scenery. Birtles, P.J. The aircraft plunged into a dry drainage canal and collided with an embankment, killing all five crew and six passengers on board. On 10 January 1954, a de Havilland Comet passenger jet operating the flight suffered an explosive decompression at altitude and crashed, killing all 35 people on board. After design modifications were implemented, Comet services resumed on October 4, 1958 with Comet 4s. The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. [10], A design team was formed in 1946 under the leadership of chief designer Ronald Bishop, who had been responsible for the Mosquito fighter-bomber. The five-stop flight from London to Johannesburg was scheduled for 21 hr 20 min. As well as thorough visual inspections of the outer skin, mandatory structural sampling was routinely conducted by both civil and military Comet operators. As the aircraft could be profitable with a load factor as low as 43 percent, commercial success was expected. This was because in 1945 no turbojet engine manufacturer in the world was drawing-up a design specification for an engine with the thrust and specific fuel consumption that could power an aircraft at the proposed cruising altitude (40,000ft (12,000m)), speed, and transatlantic range as was called for by the Type 106. This is at your risk. For VIP transport, the seating and accommodations were altered and provisions for carrying medical equipment including iron lungs were incorporated. The airline eventually became British Airways through a merger and continues flying the Boeing 747 between London and several U.S.. [176] The final Nimrod aircraft were retired in June 2011. All 43 on board were killed.
