This is the story of Graham Warner and his plucky London-based dealership/race team, the Chequered Flag, which bested all-comers in most major motorsport disciplines. A former RAF man, Warner competed at international level as a sports car driver, created the Gemini brand of Formula Juniors as a manufacturer, fielded cars on behalf of Lotus, Brabham and McLaren as an entrant, and as a talent spotter, he gave Jim Clark his maiden start in a single-seater, later running drivers such as Jackie Stewart, Jackie Ickx, Piers Courage and many more on motorsport's nursery slope. Having reached the pinnacle of Formula One with a privateer Brabham, Warner changed tack and fielded the fearsome Lancia Stratos with memorable success in rallying, before returning to his first love of aviation. Here for the first time is the full history of one of the unsung heroes of motorsport.
