Footnotes

The Martinsyde F.4 Buzzard was developed as a powerful and fast biplane fighter for the Royal Air Force, but the end of the First World War led to the abandonment of large-scale production. Fewer than 400 were eventually produced, with many exported. Powered by the 300Hp Hispano-Suiza 8 aero engine, of particular note was the Buzzard's high speed, being one of the fastest aircraft developed during World War I reaching 146 mph (235 km/h, 127 knots) at sea level and 132.5 mph (213 km/h, 115 knots) at 15,000 ft (4,600 m).
