RACE: 57th Indianapolis 500

DATE: May 28-29-30, 1973

WINNER: Gordon Johncock

AVERAGE SPEED: 159.036 mph

WHAT HAPPENED: An 11-car accident at the start left Salt Wather critically injured and caused lengthy track repairs. Rain then halted the event for the next two days. The race, run on Wednesday, was won by Johncock because he was the leader when rain resumed again after 133 laps. The race was marred by two deaths and when it stopped, only 11 cars were still on the track in what's considered one of the worst Indy 500s in history.

NOTABLE: Art Pollard was killed during a practice session on pole day, and Wednesday's race was plagued by two fatalities: driver Swede Savage and pit crew member Armando Teran.
