Supermarine Speed Spitfire
Overview
The Speed Spitfire was a Supermarine Spitfire Mk I, re-engined and modified for an attempt on the world air speed record. It was already outdated when it first flew in 1938 and, despite repeated modification, never attained a competitive performance. It was converted for photographic reconnaissance by the RAF, but proved unsuitable and was used as a general "hack" until it was scrapped in 1946.
