RACE: 54th Indianapolis 500

DATE: May 30, 1970

WINNER: Al Unser Sr.

AVERAGE SPEED: 155.749 mph

WHAT HAPPENED: Unser dominated the race and led 190 laps from the pole to join older brother, Bobby, as the first pair of brothers to win the 500. The victory also made Parnelli Jones the second competitor to win the race as a driver (1963) and as a car owner.

NOTABLE: The prize fund topped $1 million for the first time in history (by $2). Unser was the final driver to celebrate in victory lane at the south end of the pits. Victory lane was relocated the next year.
