The Vickers VC.1 Viking is a British twin-engine short-range airliner derived from the Vickers Wellington bomber and built by Vickers-Armstrongs Limited at Brooklands near Weybridge in Surrey. After the Second World War, the Viking was an important airliner with British airlines, pending the development of turboprop aircraft like the Viscount. An experimental airframe was fitted with Rolls-Royce Nene turbojets and first flown in 1948 as the world's first pure jet transport aircraft. Military developments were the Vickers Valetta and the Vickers Varsity.
The Ministry of Aircraft Production ordered three prototype Wellington Transport Aircraft to Air Ministry Specification 17/44 from Vickers-Armstrongs Limited. The specification was for a peacetime requirement for an interim short-medium haul passenger aircraft to serve until the more advanced designs specified by the Brabazon Committee (in particular, the Airspeed Ambassador and Armstrong Whitworth Apollo) could be developed. [1] [2] To speed development the aircraft used the wing and undercarriage design from the Wellington but the fuselage was new. [3] [4] Although the original contract referred to Wellington Transport Aircraft, on completion, the name Viking was chosen. [1]
The first prototype (designated the Type 491 and registered G-AGOK) was built by the Vickers Experimental Department at its wartime Foxwarren dispersal site and was first flown by 'Mutt' Summers at Wisley Airfield on 22 June 1945. [5] This aircraft crashed on 23 April 1946 [3] due to a double engine failure; no fatalities occurred as a result of the crash. [6] Following successful trials of the three prototypes the Ministry of Aircraft Production ordered 50 aircraft. [3] [7] The first BOAC aircraft flew on 23 March 1946. The prototypes were then used for trials with the Royal Air Force which led to orders for military versions (the Viking C2 (12 ordered as freighter/transports) and the modified Valetta C1).
The initial 19 production aircraft (later designated the Viking 1A) carried 21 passengers, they had metal fuselages and - except for the wing inboard of the nacelles - fabric-clad geodetic wings and tail units. Following feedback from customers, the next 14 examples, known as the Viking 1, featured stressed-metal wings and tail units. The next variant, the Viking 1B, was 28 in (71 cm) longer, carrying 24 passengers with up-rated Bristol Hercules piston engines, achieved a production run of 115. One of this batch was changed during production to so that it could be fitted with two Rolls-Royce Nene turbojet engines, with its first flight on 6 April 1948.
On 25 July 1948, on the 39th anniversary of Blériot's crossing of the English Channel, the Type 618 Nene-Viking flew Heathrow–Paris (Villacoublay) in the morning carrying letters to Bleriot's widow and son (secretary of the FAI), who met it at the airport. The flight of 222 miles (357 km) took only 34 minutes. It then flew back to London in the afternoon. It obtained a maximum speed of 415 mph (668 km/h) at 12,000 ft (3,700 m) and averaged 394 mph (634 km/h). [8] In 1954 it was bought from the Ministry of Supply and underwent the substantial conversion to Hercules 634 piston engines by Eagle Aviation to join their fleet. [9]
Production finished in 1948, including 16 for the RAF of which four were for the King's Flight, [10] but in 1952 BEA adapted some to a 38-passenger layout, taking the maximum payload up from 5,500 to 7,200 lb (2,500 to 3,300 kg). All Vikings featured a tailwheel undercarriage.
The 58th Viking (c/n 158) became the prototype of the military Valetta, of which 262 were produced for the RAF. When production of this strengthened but externally similar type ended in 1952, a flying classroom version with tricycle undercarriage was already being delivered to the Royal Air Force (RAF), called the Varsity. [11] All but one of those entered RAF service, the other example going to the Swedish Air Force. The production of 161 Varsities kept the Hurn works busy until January 1954, and they enjoyed a long service life. Six examples are preserved, including at Brooklands Museum, [12] and the Newark Air Museum. [13]
The first Viking was flown from Vickers' flight test airfield at Wisley, Surrey, by chief test pilot Joseph "Mutt" Summers on 22 June 1945 and the third aircraft built was delivered to BOAC at Hurn near Bournemouth on 20 April 1946. Upon the delivery of nine examples to BOAC for development flying, including the two remaining prototypes, British European Airways (BEA) was established on 1 August 1946 to operate airliners within Europe and these first VC.1 Vikings were transferred to the new airline. [3]
After a trial flight from Northolt to Oslo on 20 August 1946 by the newly formed BEA, the first regular Viking scheduled service commenced between Northolt and Copenhagen Airport on 1 September 1946. [14]
In all 163 Vikings were built. The initials "VC" stood for Vickers Commercial, [15] echoing the "VC" precedent set by the earlier Vimy Commercial of 1919. Vickers soon ceased to use the 'VC' letters, instead using type numbers in the 49x and 600 series, which indicated the specific customer airline.
BEA operated their large fleet of Vikings on many European and UK trunk routes for eight years. From 1951, the remaining fleet was modified with 36, instead of 27 seats, and named the "Admiral Class". BEA operated the Viking until late 1954, when the last was displaced by the more modern and pressurised Airspeed Ambassador and Vickers Viscount.
BEA sold their Vikings to several UK independent airlines for use on their growing scheduled and charter route networks. Some were sold to other European operators. An ex-BEA Viking 1B was fitted out as a VIP aircraft for the Arab Legion Air Force, mainly for the use of the King of Jordan. [16] Most Vikings had been retired from service by the mid-1960s and there are now only six extant worldwide with two surviving examples in the UK, both being under long-term major restoration.
Of the 163 aircraft built 56 aircraft were lost in accidents – the following were some notable accidents:
Of the 163 Vikings produced, only six survive today; five can be found in museums around the world, while a sixth airframe was stored at an airfield near Vienna in Austria until dismantled in late April 2023. Acquired by the Blackbushe Heritage Trust, it is returning to the UK in early May for restoration and display at Blackbushe Airport in Surrey.

The Airspeed AS.57 Ambassador is a British twin piston-engined airliner that was designed and produced by the British aircraft manufacturer Airspeed Ltd. It was one of the first postwar airliners to be produced.
The Bristol Type 175 Britannia is a retired British medium-to-long-range airliner built by the Bristol Aeroplane Company in 1952 to meet British civilian aviation needs. During development two prototypes were lost and the turboprop engines proved susceptible to inlet icing, which delayed entry into service while solutions were sought.
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner.

The Avro York was a British transport aircraft developed by Avro during the Second World War. The design was derived from the Avro Lancaster heavy bomber, several sections of the York and Lancaster being identical. Due to the importance of Lancaster production, York output proceeded slowly until 1944, after which a higher priority was placed upon transport aircraft.
The de Havilland DH.114 Heron is a small propeller-driven British airliner that first flew on 10 May 1950. It was a development of the twin-engine de Havilland Dove, with a stretched fuselage and two more engines. It was designed as a rugged, conventional low-wing monoplane with tricycle undercarriage that could be used on regional and commuter routes. A total of 149 were built; it was also exported to about 30 countries. Herons later formed the basis for various conversions, such as the Riley Turbo Skyliner and the Saunders ST-27 and ST-28.
The Vickers Viking was a British single-engine amphibious aircraft designed for military use shortly after World War I. Later versions of the aircraft were known as the Vickers Vulture and Vickers Vanellus.
The Lockheed Model 14 Super Electra was an American civil passenger and cargo aircraft built by the Lockheed Aircraft Corporation during the late 1930s. An outgrowth of the earlier Model 10 Electra, the Model 14 was also developed into larger, more capable civil and military versions.
The Vickers Varsity is a retired British twin-engined crew trainer operated by the Royal Air Force from 1951 to 1976.

Based in Salisbury, it offered an extensive network of domestic passenger and cargo flights, as well as international services to major cities in Southern and Central Africa, and a route to London. In 1960, CAA owned 15 aircraft and had 1,155 employees.
Hunting-Clan Air Transport was a wholly private, British independent airline that was founded in the immediate post-World War II period. It began trading on 1 January 1946 as Hunting Air Travel Ltd. It was a subsidiary of the Hunting Group of companies, which had come from the shipping industry and could trace its history back to the 19th century. The newly formed airline's first operating base was at Bovingdon Airport in Southeast England. Its main activities were contract, scheduled and non-scheduled domestic and international air services that were initially operated with Douglas Dakota and Vickers Viking piston airliners from the company's Bovingdon base. A change of name to Hunting Air Transport occurred in 1951. By that time, the airline had emerged as one of the healthiest and most securely financed independent airlines in Britain.
The 1961 Holtaheia Vickers Viking crash was a controlled flight into terrain incident on 9 August 1961 at Holta in Strand, Norway. The Eagle Airways Vickers 610 Viking 3B Lord Rodney was en route from London Heathrow to Stavanger Airport, Sola on an AIR Tours charter flight taking a school group for a camping holiday. The aircraft was making an instrument landing when it crashed 54 km (34 mi) north east of Stavanger. All 39 people on board died.
On 5 January 1953, a Vickers Viking airliner operated by British European Airways crashed on approach to Belfast Nutts Corner Airport, Northern Ireland. The aircraft was on a domestic flight from London Northolt Airport with 31 passengers and 4 crew on board. Twenty-four of the passengers and three crew members died in the accident.
