1969 Indianapolis 500

The 53rd International 500 Mile Sweepstakes was held at the Indianapolis Motor Speedway on Friday, May 30, 1969. Mario Andretti led 116 laps and won for car owner Andy Granatelli. Hard luck driver Lloyd Ruby was leading the race just after the midpoint, but during a pit stop, pulled away with the fueling hose still attached. He ripped a hole in the fuel tank, and was out of the race. The incident put Mario Andretti in the lead for rest of the way.

For 1969 not a single front-engined car managed to qualify for the race, and ultimately, one would never do so again. All 33 cars in the field were rear-engined, piston-powered, machines. After the historic failures of the controversial STP Granatelli Turbine machines in 1967 and 1968, USAC imposed additional restrictions that effectively rendered them uncompetitive. The annulus inlet was further reduced from 15.999 in² to 11.999 in², and the Granatelli team parked them forever.
