[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. [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. [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. 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.

They were bound for Idlewild via a stop at Gander, Newfoundland, which would be commonplace on eastbound flights. All but four Comet 2s were allocated to the RAF, deliveries beginning in 1955. The Comet, with its. [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. Avon-powered Comets were distinguished by larger air intakes and curved tailpipes that reduced the thermal effect on the rear fuselage. [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. 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.". The 2R ELINT series was operational until 1974, when replaced by the Nimrod R1, the last Comet derivative in RAF service. The Comet Story. [182] Channel Airways obtained five Comet 4Bs from BEA in 1970 for inclusive tour charters. [149], According to de Havilland's chief test pilot John Cunningham, who had flown the prototype's first flight, representatives from American manufacturers such as Boeing and Douglas privately disclosed that if de Havilland had not experienced the Comet's pressurisation problems first, it would have happened to them.

BOAC's Comet 4s were leased out to Air Ceylon, Air India, AREA Ecuador, Central African Airways[179] and Qantas Empire Airways;[81][180] after 1965 they were sold to AREA Ecuador, Dan-Air, Mexicana, Malaysian Airways, and the Ministry of Defence. [45] An EKCO E160 radar unit was installed in the Comet 4's nose cone, providing search functions as well as ground and cloud-mapping capabilities,[38] and a radar interface was built into the Comet 4 cockpit along with redesigned instruments. [4] Nevertheless, the British Overseas Airways Corporation (BOAC) found the Type IV's specifications attractive, and initially proposed a purchase of 25 aircraft; in December 1945, when a firm contract was created, the order total was revised to 10. The redesigned aircraft was named the DH.106 Comet in December 1947. [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. XK695 Comet 2R. [58], The Comet 1 featured 5,050lbf (22.5kN) de Havilland Ghost 50 Mk1 turbojet engines. 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. 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. 192 Squadron RAF Comet 2R beyond repair on 13 September 1957, and three Middle East Airlines Comet 4Cs were destroyed by Israeli troops at Beirut, Lebanon, on 28 December 1968. 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. [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. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. [171] In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955. 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. [140] Deliveries to BOAC began on 30 September 1958 with two 48-seat aircraft, which were used to initiate the first scheduled transatlantic services. [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). [82][178][181] BEA's Comet 4Bs were chartered by Cyprus Airways, Malta Airways and Transportes Areos Portugueses. [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. 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. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. Dan-Air played a significant role in the fleet's later history and, at one time, owned all 49 remaining airworthy civil Comets. ", GB-High Wycombe: "Dismantlement and relocation of Gate Guardian Comet C2 XK699. 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 [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. The airline eventually became British Airways through a merger and continues flying the Boeing 747 between London and several U.S.. The low-mounted engines and good placement of service panels also made aircraft maintenance easier to perform. Birtles, P.J. [27], The Comet was an all-metal low-wing cantilever monoplane powered by four jet engines; it had a four-place cockpit occupied by two pilots, a flight engineer, and a navigator. 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 COMET 4 remained in BOAC trans-Atlantic service though as new north American destinations . 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. [88], On 19 October 1954, the Cohen Committee was established to examine the causes of the Comet crashes. After design modifications were implemented, Comet services resumed on October 4, 1958 with Comet 4s.

Oakey, Michael, ed. [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. Cone of Silence was made into a film in 1960, and Beaty also recounted the story of the Comet's takeoff accidents in a chapter of his non-fiction work, Strange Encounters: Mysteries of the Air (1984).

First flying on 27 July 1949 the revolutionary jet powered airliner first entered service with BOAC in May 1952. ", This page was last edited on 23 February 2023, at 18:58. [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. On its return leg from Singapore it landed at Calcutta-Dum Dum Airport at 15:10 hrs local time. 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. Winchester, Jim, ed. 1 November: The inaugural flight of a BOAC De Havilland Comet 4 aircraft on the London to Sydney route took place. [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. 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. [102] Comet flights resumed on 23 March 1954. No apparent fault in the aircraft was found,[N 19] and the British government decided against opening a further public inquiry into the accident. [12] The DH 108s were later modified to test the DH.106's power controls. Principal investigator Hall accepted the RAE's conclusion of design and construction flaws as the likely explanation for G-ALYU's structural failure after 3,060 pressurisation cycles. The aircraft, registered G-ALYP, had taken off shortly before from Ciampino Airport in Rome, en route to . 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. [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. [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. 1969. 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. BOAC went on to fly the 707 on its own trans-Atlantic flights. 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. This was a mere 24 hours after the Port Authority of New York granted approval for passenger jet services following concerns over noise. Some amazing Britannia footage, Stratocruisers & DC-7Cs too! [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. At the end of the month this Comet was brought back to Hatfield from Cambridge (Marshall's) where 'radio' mods were made (JH). 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. 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. [157], The Comet 1 was the first model produced, a total of 12 aircraft in service and test. [165] Although these aircraft performed well on test flights on the South Atlantic, their range was still not suitable for the North Atlantic. Dr P. B. Walker, Head of the Structures Department at the RAE, said he was not surprised by this, noting that the difference was about three to one, and previous experience with metal fatigue suggested a total range of nine to one between experiment and outcome in the field could result in failure. Just before the 747s came along and bumped the 707s onto other services. ", "De Havilland Comet 4B airliner, serial no 6438, 1960. "Preludes and Overtures: de Havilland Comet 1". 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. For VIP transport, the seating and accommodations were altered and provisions for carrying medical equipment including iron lungs were incorporated. [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)) [52], Operationally, the design of the cargo holds led to considerable difficulty for the ground crew, especially baggage handlers at the airports.

The return flight left Tokyo on the 4th arriving at London on the 5th. ", "Metal to Metal Bonding For Aircraft Structures: Claims of the Redux Process. 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]. 2 March. [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. Depending on weight and temperature, cruise fuel consumption was 6 to 10kg (13 to 22lb) per nautical mile (1.2 miles; 1.9 km), the higher figure being at the lower altitude needed at high weight. #dehavilland #comet #dehavillandcomet #boac #route #londontotokyo #schedule #1953 #todayinhistory #unitedkingdom #uk #japan #flag .

[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. ), BOAC, and de Havilland. 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. [131], Development flying and route proving with the Comet 3 allowed accelerated certification of what was destined to be the most successful variant of the type, the Comet 4. 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. $75.00. [169] The Comet 3 was destined to remain a development series since it did not incorporate the fuselage-strengthening modifications of the later series aircraft, and was not able to be fully pressurised.

As BOAC introduced the world to the Comet 4 and air travel to the world at the dawn of the jet age, they left tyre tracks across a game park in Kenya, a trail of sparks at both Stansted in Essex and Rome, stripped trees of their leaves in Rome (again), and reduced the elevation of a hill outside Madrid by a foot or so. 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. [175][N 24], The last two Comet 4C aircraft produced were modified as prototypes (XV148 & XV147) to meet a British requirement for a maritime patrol aircraft for the Royal Air Force; initially named "Maritime Comet", the design was designated Type HS 801. [74], In their first year, Comets carried 30,000 passengers. "The Daily Express were offering one reader the chance to win a seat on the first . "[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. [173] This variant became the Hawker Siddeley Nimrod and production aircraft were built at the Hawker Siddeley factory at Woodford Aerodrome.

Flights commenced on 4 October 1958 with the de Havilland Comet 4, bringing jet travel to the crossing for the first time . ", "On This Day: Comet inaugurates the jet age.". [145], In the 1960s, orders declined, a total of 76 Comet 4s being delivered from 1958 to 1964. Herman. [61] Comet 1s subsequently received more powerful 5,700lbf (25kN) Ghost DGT3 series engines. Now from a BOAC 1971 Timetable. Here we have a superbly illustrated trade card, depicting a B.O.A.C. 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. BOAC uses the Comet 4, Qantas the Boeing 707. [N 20], The issue of the lightness of Comet 1 construction (in order to not tax the relatively low thrust DeHavilland Ghost engines), had been noted by DeHavilland test pilot John Wilson, while flying the prototype during a Farnborough flypast in 1949.

Trischler, Helmuth and Stefan Zeilinger, eds. [141] The last Comet 4 variant, the Comet 4C, first flew on 31 October 1959 and entered service with Mexicana in 1960. [N 8] Revised first orders from BOAC and British South American Airways[N 9] totalled 14 aircraft, with delivery projected for 1952.

The American jets were larger, faster, longer-ranged and more cost-effective than the Comet. 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. [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. G-APDH Comet-4 Jet aircraft left London on 1st April and arrived at Tokyo on April 3rd. In command was Capt Tom Stoney, manager of BOAC's Comet Flight. The most extensive modification resulted in a specialised maritime patrol derivative, the Hawker Siddeley Nimrod, which remained in service with the Royal Air Force until 2011, over 60 years after the Comet's first flight. [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. Ordered by Kuwait Airways, Middle East Airlines, Misrair (later United Arab Airlines), and Sudan Airways, it was the most popular Comet variant. 1961: West express A new Qantas route from London to Perth has refuelling stops in Tehran, Karachi,. 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 MoT subsequently backed BOAC's order of Conway-powered Boeing 707s. [18] Tracing fuselage failure points proved difficult with this method,[18] and de Havilland ultimately switched to conducting structural tests with a water tank that could be safely configured to increase pressures gradually. [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. [20] One window frame survived 100psi (690kPa),[21] about 1,250 percent over the maximum pressure it was expected to encounter in service. The Imperial War Museum Duxford has a Comet 4 (G-APDB), originally in Dan-Air colours as part of its Flight Line Display, and later in BOAC livery at its AirSpace building. Worldwide International 134457089011 [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. [48], Diverse geographic destinations and cabin pressurisation alike on the Comet demanded the use of a high proportion of alloys, plastics, and other materials new to civil aviation across the aircraft to meet certification requirements. Pen and Sword, 2013. [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. The Comet gave BOAC four years lead in modern jet airliners over the rest of the world. [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. 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. [103], "The cost of solving the Comet mystery must be reckoned neither in money nor in manpower. [82], Both early accidents were originally attributed to pilot error, as over-rotation had led to a loss of lift from the leading edge of the aircraft's wings. (Pan Am's DC-6B was scheduled for 46 hours 45 minutes). These improvements were possible largely because of Avon engines, with twice the thrust of the Comet 1's Ghosts. [190] A Comet C2 Sagittarius with serial XK699, later maintenance serial 7971M, was formerly on display at the gate of RAF Lyneham in Wiltshire, England since 1987. [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. Nigeria Airways timetable August 1965 - page 1 Entering service in 1969, five Nimrod variants were produced. [147] The Bruntingthorpe Aerodrome also displays a related Hawker Siddeley Nimrod MR2 aircraft. Mk.1. For the 1930s racing aircraft, see, "Comet (aircraft)" redirects here. [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. Jones, Barry. [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. There was accommodation for 36 passengers in two cabins and pressurization enabled it to fly at levels over 12,000m (40,000 feet). [140] Olympic Airways was the only other customer to order the type. BOAC DE HAVILLAND Comet 4 Radio Maintenance Schedule - Original And Rare - $73.31. 1 January. Sponsored. BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. Initially used for development, training and route proving before the inaugural jet service to Jo,burg. [137] 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. Green and Swanborough April 1977, p. 174. [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. The aircraft plunged into a dry drainage canal and collided with an embankment, killing all five crew and six passengers on board. [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. In 1962, BOAC and the British steamship company Cunard formed BOAC-Cunard Ltd, operating services to North America, the Caribbean and South America.

[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. [57] The Comet's buried-engine configuration increased its structural weight and complexity. This simply meant that the planes landed on solid ground at airports rather than water. [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. 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. [63] Comet commercial flights would not resume until 1958. [139] The Comet 4A ordered by Capital Airlines was instead built for BEA as the Comet 4B, with a further fuselage stretch of 38in (970mm) and seating for 99 passengers.
