FS2004/FSX K5054 Spitfire Prototype. The Spitfire represents the pinnacle of inline-piston engined interceptor design, and has become (arguably) THE timeless classic that other aircraft are compared too. Its designer, R.J Mitchell, has become recognized as one of the all time greats in cutting edge aviation design. Work on K5054 started in December 1934. K5054 was named Supermarine Spitfire in March 1936. K5054 took off on its maiden flight at 16.30 on March 5th 1936 from Eastleigh Aerodrome in Hampshire. The flight lasted just eight minutes. The flight was such a revelation that on landing test pilot Summers said of K5054 "Don't touch a thing". Tested in FS2004/FSX/FSX Acceleration, Windows 7/8. Gmax model by A.F. Scrub.
