context_page_description: The Bristol Ten-seater and Bristol Brandon were British single-engine biplane transport aircraft built by the Bristol Aeroplane Company in the early 1920s. Only three were built, two of which were used as civil transports and one of which served with the Royal Air Force.
context_section_description: In 1919 and 1920, Frank Barnwell, chief designer of the Bristol Aeroplane Company, considered designs for a commercial transport aircraft, ranging from single-engine, three-seat aircraft to four-engine aircraft carrying ten passengers, none of which were built. Early in 1921, the British government decided to provide subsidies for approved airlines, so Bristol's management authorised Barnwell to proceed with a design for a single-engined transport aircraft. It was intended to be powered by a Bristol Jupiter engine, but this had not yet been type-approved, so the initial prototype was fitted with a Napier Lion engine instead.
  The Lion-engined prototype, the Bristol Type 62, or Bristol Ten-seater, with the registration G-EAWY first flew on 21 June 1921. The Ten-seater was a large, two-bay biplane, with a cabin for nine passengers and a forward cockpit for the single pilot.
  The second aircraft, the Bristol Type 75 was powered by the preferred Jupiter engine, which was mounted forward of a fireproof bulkhead, with the entire engine installation (or "power-egg") capable of being swung open like a gate to allow easy access to the rear of the engine. The Type 75 was designed to accommodate eight passengers and two crew. This aircraft, registered G-EBEV, first flew in July 1922. A third aircraft, the Bristol Type 79 was ordered by the Air Council to meet a requirement (Specification 32/22) for a single-engined ambulance landplane for the Royal Air Force. It was fitted with wings of greater chord, and had accommodation for three stretchers and an attendant or two stretchers and four sitting patients.
