 and two prototypes were lost while solutions were found.

By the time development was completed, "pure" jet airliners from France, United Kingdom and the United States were about to enter service, and consequently, only 85 Britannias were built before production ended in 1960. Nevertheless, the Britannia is considered one of the landmarks in turboprop-powered airliner design and was popular with passengers. It became known by the title of "The Whispering Giant" for its quiet exterior noise and smooth flying, although the passenger interior remained less tranquil.

 run necessitated a 48-seat limit with a requirement for sufficient fuel for the lengthy stage. On 5 July 1949, the Ministry of Supply ordered five prototypes to this specification with the understanding that BOAC would contract for an additional 25 production examples. BOAC purchased options for 25 aircraft on 28 July, to be powered initially with the Centaurus engine but to be re-fitted with the Proteus when available. In November 1948, the Type 175 design was revised again to accommodate 74 passengers and a longer span wing in a contemplated long-range version aimed at long-haul Empire and transatlantic routes rather than the medium haul Empire routes originally planned. On reflection, BOAC decided that only a Proteus-engined aircraft was worth working on, necessitating a further redesign with Bristol eliminating the Centaurus option.

Prototypes and production

 G-ALBO, with Bristol Chief Test Pilot A.J. "Bill" Pegg at the controls, flew for the first time on 16 August 1952 at Filton Aerodrome. The maiden flight was eventful as the over-sensitive flying controls led to a wild pitching before Pegg restored control. During the landing approach, smoke filled the cockpit and the main undercarriage boogie was stuck in its cycle, only fully deploying seconds before landing. The "snags" proved to be minor and by September, the prototype was cleared to perform at the 1952 SBAC Display at Farnborough where spectators commented on the "quietness" of the giant airliner.

s crashed without explanation, and the Air Ministry demanded the Britannia undergo lengthy tests. Further delays were attributed to teething engine problems with the loss in December 1953 of the second prototype, G-ALRX, caused by a failed reduction gear that led to an engine fire and the aircraft landing on the mudflats of the Severn Estuary. Resolving inlet icing issues also took time. The first prototype G-ALBO was subsequently modified to more closely approximate a production standard but was retained by the company to undergo engine testing and development.
Bristol revised the design into a larger transatlantic airliner for BOAC, resulting in the Series 200 and 300, with the Britannia 300LR (Long-Range) seen as "eminently suitable" for BOAC's services between London and Sydney. Qantas

During the first eight months of operational trials, a total of 16 in-flight engine failures and 49 unscheduled engine changes punctuated the ongoing engine dilemma and delayed the in-service date until February 1957, roughly two years late.

Operational history

Following an extended period of uneventful development flying trials and the fitting of a modified Proteus 765 series that greatly alleviated the number of breakdowns, a full Certificate of Airworthiness was awarded at the end of 1955. Consequently, the first two Model 102s were delivered to BOAC on 30 December 1955 for crew training. The Model 102 began scheduled service on 1 February 1957 with a BOAC flight between London and Johannesburg. By August 1957, the first 15 Model 102 aircraft had been delivered to BOAC. The last 10 aircraft of the order were built as Series 300 aircraft for transatlantic operations. In April 1959, a Model 102 Britannia was leased by BOAC to Ghana Airways

 and London, several more Britannias were purchased by the airline in the early 1960s. The Model 102 was eventually made available to other BOAC associates, including Cathay Pacific, Central Africa, East African, Nigeria and Malayan airlines.

 (RAF) instead. The production series of three Model 252 and 20 Model 253 aircraft were purchased by RAF Transport Command in 1959, assigned the designation Britannia C.2 (first Model 252 series) and C.1 (Model 253 series). Those in RAF service were allocated the names of stars, such as "Arcturus", "Sirius" and "Vega". On retirement from the RAF in 1975, many Model 200 series were subsequently used by independent civil operators for cargo operations, harkening back to their original intended role.

Although the Bristol Model 302 was built first as part of the original BOAC order, BOAC released this series to other airlines; Aeronaves de Mexico took two Model 302s which entered service in December 1957. The 18 Bristol Britannia 312s for BOAC were delivered from September 1957 with its service introduction on the first ever non-stop flight from London to Canada on 19 December 1957. In late December 1957 BOAC began regular Britannia flights London to New York. Other airlines, such as Israel

BOAC ordered seven Model 302s but never took delivery, instead they were taken on by airlines including Aeronaves de México and Ghana Airways.

. Due to the extended development instead of a projected production of 180 Britannias, only 80 were sold. The negative experience with the development of the Britannia caused BOAC to be more cautious towards other British-made aircraft such as the Vickers VC-10. Throughout the Britannia's lifespan, the engine icing condition remained a "continual potential hazard" that flight crews ultimately learned to manage with a "high-lo" flight regime that minimized the danger, although the problems of the Britannia can mainly be linked to that of a manufacturer undertaking an innovative airframe design matched to an unproven engine, a design syndrome that remained particularly daunting.

  • On 20 April 1967, a Globe Air Britannia 313 was on a flight from Bangkok to Basel with intermediate stops at Colombo, Mumbai (Bombay) and Cairo.

  • On 16 February 1980, a Britannia 253F crashed at Billerica, Massachusetts, shortly after taking off from Boston. The probable cause of the accident was degraded aerodynamic performance beyond the flight capabilities of the aircraft resulting from an accumulation of ice and snow on the airframe before takeoff and a further accumulation of ice when the aircraft was flown into moderate to severe icing conditions following takeoff. Contributing to the cause of the accident were encounters with wind shear, downdrafts, and turbulence during the climb. Of eight crew and passengers on board, there were seven fatalities with one seriously injured.
