Spitfghter mark 1 airplane - Essay Example It continued in these roles until the mid-1950, when production stopped. Until today, the Spitfire continuous to be a favourite aircraft with 53 being airworthy and many more being used as displays in air museums and schools (Zandvoort 1957). The Spitfires design started in 1931 when Mitchell wanted to meet the Air ministry’s new specifications for a modern craft that was capable of 250 mph. The design did not get off to a good start, the first one named Super-marine type 224, had a Rolls-Royce steam-cooled Griffon engine.
