boac comet routes

1961: West express A new Qantas route from London to Perth has refuelling stops in Tehran, Karachi,. Birtles, P.J. Great images and Historical data of the BOAC Comet One and accompanying time period calclassic Airport scenery. de Havilland Comet 1 jet airliner . During a radio communication about weather conditions, the conversation was abruptly cut off. 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. [104], During the investigation, the Royal Navy conducted recovery operations. The COMET 4 remained in BOAC trans-Atlantic service though as new north American destinations . #dehavilland #comet #dehavillandcomet #boac #route #londontotokyo #schedule #1953 #todayinhistory #unitedkingdom #uk #japan #flag . BOAC then started flying Short S25 Sunderland III flying boats to West Africa. "The Daily Express were offering one reader the chance to win a seat on the first . Both of these aeroplanes would continue to operate side by side until the formation of British Airways PLC in 1974. [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. BOAC COMET 4 Captains Folder Africa routes original 1960s document - EUR 54,29. 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. BOAC started the first regular round-the-world service by Britannia 312 aircraft, operating via San Francisco and Hong Kong. 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 [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. [177], The original operators of the early Comet 1 and the Comet 1A were BOAC, Union Aromaritime de Transport and Air France. 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. In April 1960, 13 Comets, 19 Britannias and 6 DC-7Cs. In 1962, BOAC and the British steamship company Cunard formed BOAC-Cunard Ltd, operating services to North America, the Caribbean and South America. 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. $430.00. Within a year of entering airline service, problems started to emerge, three Comets being lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. 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. [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. The court acted under the provisions of Rule 75 of the Indian Aircraft Rules 1937. [188] Other fatal Comet 4 accidents included a British European Airways crash in Ankara, Turkey, following instrument failure on 21 December 1961, a United Arab Airlines Flight 869 crash during inclement weather near Bombay, India, on 28 July 1963, and the terrorist bombing of Cyprus Airways Flight 284 off the Turkish coast on 12 October 1967. Comets quit flying the North Atlantic in October 1960 (but reportedly made a few flights in summer 1964). [164] The first production aircraft (G-AMXA) flew on 27 August 1953. [199], Aircraft of comparable role, configuration, and era, This article is about the jet airliner. ", "De Havilland Comet 4B airliner, serial no 6438, 1960. To achieve optimum efficiency with the new powerplants, the air intakes were enlarged to increase mass air flow. [116] Based on these findings, Comet 1 structural failures could be expected at anywhere from 1,000 to 9,000 cycles. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. BOAC would go on to dominate the London-New York route in the 1960s and early 1970s with Pan Am, but when it came to airliners the Americans were the long-term winners. 106 Comet.". [114] The fuselage frames did not have sufficient strength to prevent the crack from propagating. Explore our past: 1969. Prototype Comet 1 Assembly Shop It was later determined that the Comet's wing profile experienced a loss of lift at a high angle of attack, and its engine inlets also suffered a lack of pressure recovery in the same conditions. Following its first flight, the special order Comet 4C was described as "the world's first executive jet. [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. BOAC flew two de Havilland Comet 4 aircraft between London and New York International Airport, Idlewild. [194] A Comet 4B (G-APYD) is stored in a facility at the Science Museum at Wroughton in Wiltshire, England. The Abell Committee focused on six potential aerodynamic and mechanical causes: control flutter (which had led to the loss of DH 108 prototypes), structural failure due to high loads or metal fatigue of the wing structure, failure of the powered flight controls, failure of the window panels leading to explosive decompression, or fire and other engine problems. 14.". [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. No apparent fault in the aircraft was found,[N 19] and the British government decided against opening a further public inquiry into the accident. Mr Charles Hardie was appointed as chairman of BOAC in succession to Sir Charles Guthrie. The prototype Comet 3 first flew in July 1954 and was tested in an unpressurised state pending completion of the Cohen inquiry. Registered 18/09/1951 to de Havilland Aircraft Company. New opportunities VINTAGE 1953 BOAC AIRLINES SPEEDBIRD ROUTE MAP TIMETABLE. G-ALYP a/f 6003. BOAC went on to fly the 707 on its own trans-Atlantic flights. [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. ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. Menu. G-ALYR a/f 6004. Photo: Getty Images 2 December: The inaugural flight of a BOAC Comet 4 aircraft on the London to Johannesburg route took place. Chief designer Bishop chose the Comet's embedded-engine configuration because it avoided the drag of podded engines and allowed for a smaller fin and rudder since the hazards of asymmetric thrust were reduced. [57] The Comet's buried-engine configuration increased its structural weight and complexity. Hall, Geoffrey de Havilland and Bishop were immediately called to the scene, where the water tank was drained to reveal that the fuselage had ripped open at a bolt hole, forward of the forward left escape hatch cut out. The inquiry concluded that the aircraft had encountered extreme negative G forces during takeoff; severe turbulence generated by adverse weather was determined to have induced down-loading, leading to the loss of the wings. Investigators did not consider metal fatigue as a contributory cause. Hill, Malcolm L. "de Havilland's Comet: Pushing the Boundaries.". They were bound for Idlewild via a stop at Gander, Newfoundland, which would be commonplace on eastbound flights. He stated "Every time we pulled 2 1/2-3G to go around the corner, Chris found that the floor on which he was standing, bulging up and there was a loud bang at that speed from the nose of the aircraft where the skin 'panted' (flexed), so when we heard this bang we knew without checking the airspeed indicator, that we were doing 340 knots. After design modifications were implemented, Comet services resumed on October 4, 1958 with Comet 4s. [191][192] In 2012, with the planned closure of RAF Lyneham, the aircraft was slated to be dismantled and shipped to the RAF Museum Cosford where it was to be re-assembled for display. 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. 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. First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. In 1949 BOAC introduced the first of what was termed an 'all-land' service using Canadair Argonauts on their London to Hong Kong/Tokyo route, via Rome, Cairo, Basra, Karachi, Calcutta, Rangoon and Bangkok. Flights commenced on 4 October 1958 with the de Havilland Comet 4, bringing jet travel to the crossing for the first time . [94], The inquiry's recommendations revolved around the enforcement of stricter speed limits during turbulence, and two significant design changes also resulted: all Comets were equipped with weather radar and the "Q feel" system was introduced, which ensured that control column forces (invariably called stick forces) would be proportional to control loads. 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. Extensively modified at the factory, the aircraft included a VIP front cabin, a bed, special toilets with gold fittings and was distinguished by a green, gold and white colour scheme with polished wings and lower fuselage that was commissioned from aviation artist John Stroud. The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. : This photo of Super VC10 G-ASGD taken in Mexico in 1972 shows the Speedbird livery without Cunard titles. In September 1972 the airlines of BOAC and BEA began a merger, eventually forming British Airways on 31 March 1974. [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. Jones, Barry. In command was Capt Tom Stoney, manager of BOAC's Comet Flight. [170] Only two Comet 3s began construction; G-ANLO, the only airworthy Comet 3, was demonstrated at the Farnborough SBAC Show in September 1954. [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. On its return leg from Singapore it landed at Calcutta-Dum Dum Airport at 15:10 hrs local time. 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. The first Comet 4B flew on 27 June 1959 and BEA began Tel Aviv to London-Heathrow services on 1 April 1960. [156] In response to the Comet tragedies, manufacturers also developed ways of pressurisation testing, often going so far as to explore rapid depressurisation; subsequent fuselage skins were of a greater thickness than the skin of the Comet. The operation was short-lived and was dissolved in 1966. [8] First-phase development of the DH.106 focused on short- and intermediate-range mailplanes with small passenger compartments and as few as six seats, before being redefined as a long-range airliner with a capacity of 24 seats. [135] The Comet 4 enabled BOAC to inaugurate the first regular jet-powered transatlantic services on 4 October 1958 between London and New York (albeit still requiring a fuel stop at Gander International Airport, Newfoundland, on westward North Atlantic crossings). 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. Brand New. [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. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. This simply meant that the planes landed on solid ground at airports rather than water. [183] Dan-Air bought all of the surviving flyable Comet 4s from the late 1960s into the 1970s; some were for spares reclamation, but most were operated on the carrier's inclusive-tour charters; a total of 48 Comets of all marks were acquired by the airline. [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. [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. "[121], Despite findings of the Cohen Inquiry, a number of myths have evolved around the cause of the Comet 1's accidents. The trip took 33 hours. The event would open up new opportunities for the aviation industry, leaving a legacy over six decades later. 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. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . 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. [49] The Comet's high cabin pressure and fast operating speeds were unprecedented in commercial aviation, making its fuselage design an experimental process. [62], From the Comet 2 onwards, the Ghost engines were replaced by the newer and more powerful 7,000lbf (31kN) Rolls-Royce Avon AJ.65 engines. "[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 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. [182] Channel Airways obtained five Comet 4Bs from BEA in 1970 for inclusive tour charters. 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. [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. BOAC DE HAVILLAND COMET 4 RADIO MAINTENANCE SCHEDULE - ORIGINAL AND RARE 384272193709 [72], Prince Philip returned from the Helsinki Olympic Games with G-ALYS on 4 August 1952. [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)) The Comet was withdrawn from service and extensively tested. Here we have a superbly illustrated trade card, depicting a B.O.A.C. The de Havilland DH.106 Comet was the world's first commercial jet airliner. [34][N 11] For passengers used to propeller-driven airliners, smooth and quiet jet flight was a novel experience. BCPA had actually ordered three Comet 2s from de Havilland, although the agreement had never been fully finalised. [42] Power was syphoned from all four engines for the hydraulics, cabin air conditioning, and the de-icing system; these systems had operational redundancy in that they could keep working even if only a single engine was active. There was accommodation for 36 passengers in two cabins and pressurization enabled it to fly at levels over 12,000m (40,000 feet). [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. The return flight left Tokyo on the 4th arriving at London on the 5th. ", "De Havilland Comet 4C G-BDIX Interior View Scottish Museum of Flight. [74], In their first year, Comets carried 30,000 passengers. [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. 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. Examination of the cockpit controls suggested that the pilot may have inadvertently over-stressed the aircraft when pulling out of a steep dive by over-manipulation of the fully powered flight controls. Design and construction flaws, including improper riveting and dangerous concentrations of stress around some of the square windows, were ultimately identified. [88], On 19 October 1954, the Cohen Committee was established to examine the causes of the Comet crashes. [13] Sprite fittings were retained on production aircraft. Smith, Adrian. Winchester, Jim, ed. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. Photo RuthAs CCA-3 First out of the blocks as those schoolboys have told us was the Comet 1. 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. [90], The Comet's second fatal accident occurred on 2 May 1953, when BOAC Flight 783, a Comet 1, registered G-ALYV, crashed in a severe thundersquall six minutes after taking off from Calcutta-Dum Dum (now Netaji Subhash Chandra Bose International Airport), India,[91] killing all 43 on board. [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. AUSTRALIA 1959 BOAC Comet 4 illustrato FFC da Sydney a Singapore - EUR 3,97. [17] The majority of hydraulic components were centred in a single avionics bay. [58], The Comet 1 featured 5,050lbf (22.5kN) de Havilland Ghost 50 Mk1 turbojet engines. XK695 Comet 2R. All outstanding orders for the Comet 2 were cancelled by airline customers. "The Dawn of the Jet Age in Austerity Britain: David Lean's The Sound Barrier". Simons, Graham M. "Comet! [85], On 26 October 1952, the Comet suffered its first hull loss when a BOAC flight departing Rome's Ciampino airport failed to become airborne and ran into rough ground at the end of the runway. [89] A fictionalised investigation into the Comet's takeoff accidents was the subject of the novel Cone of Silence (1959) by Arthur David Beaty, a former BOAC captain. The Comet, with its. [82][178][181] BEA's Comet 4Bs were chartered by Cyprus Airways, Malta Airways and Transportes Areos Portugueses. 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. [102], Media attention centred on potential sabotage;[88] other speculation ranged from clear-air turbulence to an explosion of vapour in an empty fuel tank. For the 1930s racing aircraft, see, "Comet (aircraft)" redirects here. "Comet Service To South America Planned" (News). [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. [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. Atkinson, R. J., W. J. Winkworth and G. M. Norris. ", "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. The exception was G-ARVC that spent a year in full Nigeria Airways livery, during 1966. [113], The RAE also reconstructed about two-thirds of G-ALYP at Farnborough and found fatigue crack growth from a rivet hole at the low-drag fibreglass forward aperture around the Automatic Direction Finder, which had caused a catastrophic break-up of the aircraft in high-altitude flight. [100][N 18] BOAC also voluntarily grounded its Comet fleet pending investigation into the causes of the accident. In August 1953 BOAC scheduled the nine-stop London to Tokyo flights by Comet for 36 hours, compared to 86 hours and 35 minutes on its Argonaut piston airliner. 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. Airline Mug BOAC British Overseas Airways Corporation 5" Ceramic. Witnesses observed the wingless Comet on fire plunging into the village of Jagalgori,[92] leading investigators to suspect structural failure. [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 first in a dramatic series of crashes of the DH106 Comet was at Rome on 26 October 1952 when a BOAC aircraft failed to get properly airborne in taking off. Rival manufacturers heeded the lessons learned from the Comet when developing their own aircraft. Entering service in 1969, five Nimrod variants were produced. A large portion of the aircraft was recovered and reassembled at Farnborough,[93] during which the break-up was found to have begun with a left elevator spar failure in the horizontal stabilizer. This artificial feel was the first of its kind to be introduced in any aircraft. [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. [86][87] The accident was the first fatal jetliner crash. [41] The undercarriage could also be lowered by a combination of gravity and a hand-pump. Avon-powered Comets were distinguished by larger air intakes and curved tailpipes that reduced the thermal effect on the rear fuselage. Surviving Comet 1s can be seen on view at the RAF Museum Cosford and the DeHavilland Museum at Salisbury Hall, London Colney. . 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). 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. Before the Elba accident, G-ALYP had made 1,290 pressurised flights, while G-ALYY had made 900 pressurised flights before crashing. [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. FOR SALE! [110] The Comet's Certificate of Airworthiness was revoked, and Comet 1 line production was suspended at the Hatfield factory while the BOAC fleet was permanently grounded, cocooned and stored. The airline eventually became British Airways through a merger and continues flying the Boeing 747 between London and several U.S.. 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 (from the structure)[126]. [13][18][19] The entire forward fuselage section was tested for metal fatigue by repeatedly pressurising to 2.75 pounds per square inch (19.0kPa) overpressure and depressurising through more than 16,000 cycles, equivalent to about 40,000 hours of airline service. [77][78] A slightly longer version of the Comet 1 with more powerful engines, the Comet 2, was being developed,[79] and orders were placed by Air India,[80] British Commonwealth Pacific Airlines,[81] Japan Air Lines,[82] Linea Aeropostal Venezolana,[82] and Panair do Brasil. BOAC SOUTH PACIFIC Route Airline Menu Ny -San Francisco-Honolulu-Nandi-Sydney - $38.98. A BOAC Comet 1 at London Airport in 1955. [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. On 3 March 1953, a new Canadian Pacific Airlines Comet 1A, registered CF-CUN and named Empress of Hawaii, failed to become airborne while attempting a night takeoff from Karachi, Pakistan, on a delivery flight to Australia. On the Eastern route there was a 22% increase in traffic but on the Southern route only a 2% increase." [53][54], The Comet was powered by two pairs of turbojet engines buried in the wings close to the fuselage. "Database: D.H. 106 Comet". 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. [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. The flight to Johannesburg lasted 18 hours and 40 minutes. [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. [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. 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. This was short lived as later that year Britannias took over that route. ", "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 later years we realised that these were the indications of how flimsy the structure really was. [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. 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.
