The Blackburn Sidecar was a two-seat ultra-light aircraft built by the Blackburn Aeroplane & Motor Company at Brough in 1919. There is no evidence that it ever flew.
The side-by-side two-seat Sidecar was built by the Blackburn Aeroplane & Motor Co. Ltd. at Brough in 1919 for Mr.K.M Smith.
It was a small mid-winged aircraft, with wings and other flying surfaces of constant chord. It had no fixed tail surfaces. The triangular cross-section fuselage was unusually deep, such that the undercarriage cross-axle was attached to the keel or bottom longeron.
The sole Sidecar, eventually registered G-EALN on 26 August 1920, was exhibited at Harrods Department store in Knightsbridge during March 1919. It did not fly with the low-powered Gnat. About July 1921 the aircraft was sold to Mr. Haydon-White, Blackburn's London manager who had it re-engined with a 100abbr=offNaNabbr=off Anzani radial. By October 1921 it was logged as unairworthy. There is no record of it flying during these four months.
