1958 | Treacherous Turn
• As front-row drivers Dick Rathmann and Ed Elisian battled for position on the opening lap, Elisian drove under Rathmann and lost control, sliding up the banking into Rathmann and triggering a 15-car pileup. A half-dozen drivers were injured, and popular Pat O'Connor, who had been featured on the cover of SI less than a week earlier, was killed after his car rolled end over end.
1987 | At the End of His Rope
• For 170 laps, Mario Andretti had led the race, but on Lap 177, ahead by more than two miles, his engine sputtered and he ducked into the pits. Back on the track, Andretti stalled with eight laps to go, bringing the caution flag out. Roberto Guerrero briefly took the lead before Al Unser overtook him on the way to his fourth Indy win. "There was no one who could challenge us today," said a disappointed Andretti, who would win Indy only once in 29 tries. "No one."
1967 | Man of Vision
• A.J. Foyt avoided a last-lap five-car crash, driving through the smoke unscathed to take his third win. "When I peeked around the number 4 turn and saw all that smoke, I said, 'Oh, God!'" Foyt told SI. "I popped her into low and pulled down to the inside of the track. And as soon as I could see where everybody was spinning to, I stood on it again and drove her on through to the finish line."
1964 | A Black Day
• The last crash to claim multiple drivers' lives occurred on the second lap, when Dave MacDonald spun and hit the inside wall. His car exploded, and Eddie Sachs plowed directly into MacDonald's car, dying instantly. MacDonald died several hours later. A.J. Foyt would take his second checkered flag in a race that was delayed for one hour and 45 minutes.
1924 | Two to Go
• Leading after the first lap, Joe Boyer's Duesenberg Special gave out on the second, and he parked it. L.L. Corum's car of the same make was struggling in fourth place halfway through the race. On Lap 111, Fred Duesenberg called Corum to the pits to let the more experienced Boyer finish the job. Boyer took the lead for good on Lap 177, and he and Corum were declared cowinners.
