Its now been 15 years since the death of racing great Aryton Senna, who was killed when he crashed at the San Marino Grand Prix in Italy. I got to know Aryton while working with the Toleman F1 team in 1984. He is the only 3 time winner of the Detroit Grand Prix, as well as a 3 time Formula One World Driving Champion. HIs qualifying laps on the old Detroit street circuit were scintillating. The Aryton Senna Foundation that he started to help children in Brazil is still active. His dedication and perseverance are an inspiration to me still.
