The death of Jim Clark shocked the motor racing world to the core, just as the tragedies of 1955 and 1994. Twice World Champion and winner of the 1965 Indianapolis 500, this quietly spoken and reserved Scot was revered on both sides of the Atlantic. But for his untimely death in an unexplained accident during Hockenheim’s Formula 2 race, Clark may well have won another couple of titles or more. “What can I or anyone else say,” wrote Denis Jenkinson in the May 1968 issue of Motor Sport. “Mere words are inadequate to express our feelings.” The sport had lost one of its greatest-ever stars.
