Perhaps one of these wrecks:

His first race for Lotus was at the Dutch Grand Prix in 1960, where he raced in place of John Surtees who was still racing motorcycles at the time. His race was pretty uneventful as he worked his way up to fifth place before he had to retire with a seized gearbox. The next race was at Spa in Belgium. This was the most dangerous course in Grand Prix racing, a 9 mile monster and in 1960 it took the lives of two drivers including Clark's teammate Alan Stacey. Yet in spite of this Clark would manage to finish fifth in his second Grand Prix. The next year was met with limited success and some controversy. At the Italian Grand Prix, Clark's Lotus came into contact with the Ferrari of Wolfgang von Trips. The Ferrari was propelled into the crowed killing several spectators as well as the German driver, Germany's best hope in decades.
