Vickers aircraft since 1908 ([Aeronautical books])

The Vickers E.F.B.7 was a prototype British fighter aircraft of the First World War. A twin-engined biplane, the E.F.B.7 was unsuccessful, only a single example being built. In August 1914, following the outbreak of the First World War, the British pioneer aircraft designer Howard Flanders was hired by Vickers Limited as an aircraft designer, with his first job to design a fighting aircraft to carry a Vickers 1 pounder (37 mm) cannon. (This was not the well-known pom-pom, but a smaller and lighter long recoil cannon firing less powerful ammunition.) Flanders produced a twin engined development of his earlier Flanders B.2 single-engined biplane, the E.F.B.7 (Experimental Fighting Biplane No.7).
