Brazilian racing legend Ayrton Senna retains the dubious honour of being the last Grand Prix driver to be killed whilst driving a Formula One car. An international star known for his ruthless driving style, Senna was leading the 1994 San Marino Grand Prix when he reached the Tamburello corner. His car left the track, hit the concrete retaining wall at around 135 mph and Senna was fatally injured in front of millions of TV viewers. With his blood on the race track, an overhead helicopter flashed images of the dying driver around the world as rescue workers frantically administered medical attention. After his death at Imola, the Tamburello turn was changed into a left-right chicane and the Brazilian government declared three days of national mourning for their fallen sporting hero.
