The Royal Aircraft Factory S.E.4 was a single-engined, single seat biplane designed and built at the Royal Aircraft Factory just prior to the start of the First World War. Intended to be as fast as possible, it recorded a speed of 135 mph (217 km/h), which made it the fastest aircraft in the world in 1914, but no production followed and it was soon written off in a crash.
