[edit] History
The Scion Senior was developed as an enlarged version of the Scion light transport for nine passengers. 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 sunk at sea in 1944.
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.
