ブライアン・ハート
It was towards the end of 1967 that Hart began working at the de Havilland aircraft company at Hatfield, England. The company provided training in the design and construction of airframes and aero engines. He then moved to the renowned engine builder Cosworth, but left in 1969 to form his own eponymous company to service Cosworth's Ford FVA engines. "Brian Hart Limited" was soon commissioned by Ford to work on new engine development, in a similar role to his former employer. Hart developed the Ford BDA, which would be used in Ford's rally programs throughout the 1970s.
