COMPLEX SAYS: As the three-time Formula One world champion, Ayrton Senna was one of the sport's most well-known racers and considered one of the all-time greats even before his untimely death at the 1994 San Marino Grand Prix. While leading the race on lap six, Senna's car went into a turn at 135 mph before hitting a wall. Senna was removed from his car and found to have suffered significant blood loss and head trauma before being airlifted to a hospital where he was later pronounced dead. The critically acclaimed documentary based on his life, Senna, was released last year.
