Short S.16 Alpha / Scion
Short decided that there was a need for an inexpensive light transport landplane and the high-wing Scion was developed using the small but effective Pobjoy engine. It was originally called “Alpha”, but this was changed to “Scion”.
The first of this twin engined high wing monoplane was flown in prototype form (G-ACJI) on 18 August 1933, at Gravesend Aerodrome. Later deliveries were flown from the new grass aerodrome near the works at Rochester.
The first production machine was delivered to Gandar Dower for his Aberdeen-Glasgow service, taking delivery of G-ACUV at Rochester on 27 July 1934 at Rochester.
The rest of the production batch of five were registered G-ACUW to UZ. The last was converted to a Scion II with six passenger seats.

It sold in modest numbers (for approx £2500), and the Scion was joined by the four-engined Scion Senior (capable of carrying nine passengers) in 1935. Short, however, wanted to turn its resources back to the flying-boat market. Douglas Pobjoy purchased the Scion rights in 1936, but the list price then limited sales potential and Pobjoy only built a further six in 1936 to add to Short's 16, plus another six Scion Senior's built by Short.
The Scion series served all over the British empire and for the RAF during World War II, one example surviving in Australia until 1965.
