Sage Type 2
The Sage Type 2 was a prototype British two-seat fighter aircraft of the First World War. A single-engined biplane with an enclosed cabin for its crew, only a single example was built, as more advanced aircraft became available.
==Development and design==
The long-established woodworking company, Frederick Sage & Co, which specialised in shopfitting, set up an aircraft department in early 1915,〔Gunston 2005, p.406.〕 hiring the well known test pilot and designer, E C Gordon England to lead the department, and recruiting Clifford Tinson, formerly deputy to Frank Barnwell at the Bristol Aeroplane Company early in 1916.〔Bruce 1957, p.462.〕
Tinson's first design for Sage was a two-seat fighter aircraft, the Sage Type 2. It was a small wood-and-fabric tractor biplane (in fact the two-seat Sage was smaller than many single-seaters of the time), with single-bay wings.〔Bruce 1968, p.94.〕 The pilot and gunner sat in an enclosed, glazed cabin that filled the gap between the fuselage and upper wing. Because of the lack of effective gun synchronising gear to allow a fixed gun to fire through the propeller disc, a hole was cut in the upper wing above the gunners seat, so the gunner could stand with head and shoulders above the wing, giving him a good allround field of fire for his Lewis gun, including forward over the propeller. The aircraft was powered by a Gnome Monosoupape rotary engine driving a four-bladed propeller.〔Mason 1992, p.69.〕
The prototype first flew on 10 August 1916,〔 and demonstrated good performance and manoeuvrability,〔Bruce 1968, p.69.〕 being easy to fly.〔''Flight'' 24 July 1919, p.973.〕 It was wrecked during a crash landing during a test flight at Cranwell on 20 September 1916 after the rudder post failed.〔〔''Flight'' 24 July 1919, pp.973—974.〕 No further development was carried out, as by this time, effective synchronising gear was available to the British, and the Sopwith 1½ Strutter was already in service.〔
