The Blackburn Sidecar was a two-seat side-by-side ultra-light aircraft powered by one 40-hp ABC Gnat 2-cylinder engine. It was built by the Blackburn Aeroplane & Motor Co at Brough, West Yorks, in 1919. Only one was built (G-EALN), and was owned by a certain K. M. Smith. It was exhibited at Harrods, London during March 1919, afterwards being sold to Haydon-White, whereupon it was re-engined with a 100-hp Anzani engine in 1921.
