1952: Bill Vukovich leads 150 laps until his steering pin breaks on lap 192. He stopped the car by brushing it against the outside wall, a move which prevented other cars from becoming involved in the sudden incident. Twenty-two-year-old Troy Ruttman takes the checkered flag, the youngest-ever winner. On the pole for the '52 race was Fred Agabashian's Diesel-powered racer that succumbed to supercharger trouble on lap 71.
