The Short S.22 Scion Senior was a 1930s British four-engined nine-passenger floatplane built by Short Brothers.
The Scion Senior was developed as an enlarged version of the Scion light transport for nine passengers. Unfortunately, the aircraft failed to win orders from internal airline operators, who had already adopted the De Havilland Dragon and Dragon Rapide; instead it proved attractive as a seaplane for survey and river transport purposes overseas, and the first order came from the Irrawaddy Flotilla Co. in Burma, with a promise of further orders if the first seaplane proved satisfactory. So the Scion Senior was designed basically as a seaplane with an alternative land chassis. The first two aircraft, built as floatplanes, were shipped to Rangoon as soon as they had received their Certificate of Airworthiness; the third aircraft was built as a landplane for Shorts to use as a demonstrator; the remaining three were built as floatplanes, although one (S.835, G-AENX) was actually first flown as a landplane before being converted to its intended floatplane configuration. [1]
The last aircraft built (serial number L9786) was acquired by the Air Ministry for testing flying boat hull designs particularly for the Short Sunderland. Redesignated the Scion Senior FB (for Flying Boat), it was fitted with a duralumin, flush-riveted central float and outrigger floats. During 1942, a series of trials by the Marine Aircraft Experimental Establishment (MAEE) was undertaken, determining attitude and stability characteristics of the design. The sole test example was lost at sea on 15 March 1944 off Helensburgh, Argyll, when an attempt was made to take off from the Clyde in frosty conditions. H.G. White, a Flight Test Officer at MAEE Helenburgh, died when the aircraft stalled into the water and sank. The other two members of the crew were rescued. [2]
The Scion Senior landplane was eventually sold to Palestine Air Transport in December 1938, to be based in Haifa. It was impressed into Royal Air Force service in the Middle East in February 1942 and lost in action on 22 September 1943.

Short Brothers plc, usually referred to as Shorts or Short, is an aerospace company based in Belfast, Northern Ireland. Shorts was founded in 1908 in London, and was the first company in the world to make production aeroplanes. It was particularly notable for its flying boat designs manufactured into the 1950s.
The Short Calcutta or S.8 was a civilian biplane airliner flying boat made by Short Brothers.
The Short Singapore was a British multi-engined biplane flying boat built after the First World War. The design was developed into two four-engined versions: the prototype Singapore II and production Singapore III. The latter became the Royal Air Force's main long-range maritime patrol flying boat of the 1930s and saw service against the Japanese with the Royal New Zealand Air Force during the Second World War.
The Short Shetland was a British high-speed, long-range, four-engined flying boat built by Short Brothers at Rochester, Kent for use in the Second World War. It was designed to meet an Air Ministry requirement for a very-long range reconnaissance flying boat. The design used the company's experience with large scale production of the Short Sunderland. The end of World War II prevented the Shetland from entering production; it was the first aircraft designed with a 110 volt electrical system.
The Short Mayo Composite was a piggy-back long-range seaplane/flying boat combination produced by Short Brothers to provide a reliable long-range air transport service to North America and, potentially, to other distant places in the British Empire and the Commonwealth.
The Short Admiralty Type 184, often called the Short 225 after the power rating of the engine first fitted, was a British two-seat reconnaissance, bombing and torpedo carrying folding-wing seaplane designed by Horace Short of Short Brothers. It was first flown in 1915 and remained in service until after the armistice in 1918. A Short 184 was the first aircraft to sink a ship using a torpedo, and another was the only British aircraft to take part in the Battle of Jutland.
The Short Bomber was a British two-seat long-range reconnaissance, bombing and torpedo-carrying aircraft designed by Short Brothers as a land-based development of the very successful Short Type 184.
The Short S.17 Kent was a British four-engined 15-seat biplane luxury flying boat airliner, designed and built by Shorts to meet a requirement from Imperial Airways for an aircraft with greater range than the Short Calcutta. The new aircraft was to have sufficient range to fly the stage from Mirabella, Crete, to Alexandria in Egypt without the need for refuelling stops in Italian colonial territory due to a political row which had led the Italian Government to ban British aircraft from its ports.
The Short S.16 Scion and Scion II were 1930s British two-engine, cantilever monoplanes built by Short Brothers and by Pobjoy Airmotors and Aircraft Ltd. in Rochester, Kent between 1933 and 1937. Altogether 22 Scion/Scion II aircraft were built and they provided useful service to operators working from small airstrips/water courses in many parts of the globe, including Europe, the Near and Middle East, Sierra Leone, Papua New Guinea and Australia. Many were impressed into the Royal Air Force during the Second World War, providing pilot ferry services, anti-aircraft co-operation and radar calibration duties. Of the civilian Scions, at least two were still operating in Australia in 1966, one having been re-engined with de Havilland Gipsy Minor engines.
John Lankester Parker OBE FRAeS Hon. MSLAE was Chief Test Pilot for Short Brothers from 1918 until his retirement in 1945. He joined Shorts in 1916 as a part-time test pilot and assistant to then Chief Test Pilot Ronald Kemp, having been recommended for the post by Captain, later Admiral Sir, Murray Sueter, RNAS. By the time he retired he was a director of the company.
The Short S.8/8 Rangoon was a 1930s British three-engined biplane flying boat, designed and built by Short Brothers for the Royal Air Force.
The Kawanishi H3K, also known as Navy Type 90-2 Flying Boat (九〇式二号飛行艇), was a Japanese biplane military flying boat from the interwar period. The H3K was a development of the Short S.8/8 Rangoon. The first of the H3Ks was built by Short Brothers and the remaining four by Kawanishi in Japan.
Short Folder is a generic name often applied to several different Short Brothers' aircraft types designed and built prior to and during World War I. Short Brothers developed and patented folding wing mechanisms for ship-borne aircraft from 1913; the wings were hinged so that they folded back horizontally alongside the fuselage, reducing the storage space required for stowing them aboard ship.
The Short S.11 Valetta was a 1930s British passenger monoplane designed and built by Short Brothers at Rochester.
The Short Type 320, also known as the Short Admiralty Type 320, was a British two-seat reconnaissance, bombing and torpedo-carrying "folder" seaplane of the First World War.
The Short S.7 Mussel was a single-engined two-seat monoplane built by Short Brothers to test the performance of their duralumin monocoque floats. Two were built.
The Parnall Pike was a 2/3-seat biplane reconnaissance aircraft, capable of operating off carrier decks or from water, built to an Air Ministry specification in 1927. Only one was constructed.
The Short S.41 was a British single-engined biplane built for the Royal Navy in 1912. Capable of being operated either on wheels or floats, it was successful enough for a further two similar aircraft to be built, with the type remaining in use until the early years of the First World War.
The Short S.45 — also known as the Short T.5 after its naval serial number — was a training biplane built for Britain's Royal Navy by Short Brothers in 1912. It was the forerunner of another three identical aircraft delivered to the Royal Navy and Royal Flying Corps during 1912 and 1913. The Royal Naval Air Service was still operating the type when World War I broke out in 1914.
The Short Admiralty Type 81 was a series of British two-seat floatplanes built prior to the First World War, and used by the Royal Naval Air Service in the early years of the war. They were powered by 160 hp (120 kW) Gnome Lambda-Lambda 14 cylinder two-row rotary engines and had folding wings to aid storage on ship, hence the popular name Short Folder, shared with a number of other seaplanes made by Short Brothers.
