Opening lap crash – Death of Pat O'Connor For the second year in a row, the starting grid was assembled single-file in the pit lane. The cars were instructed to pull away and assemble into the official eleven rows of three after they entered the racing surface. Confusion occurred on the pace lap, however, as the three drivers of the front row (
Dick Rathmann,
Ed Elisian, and
Jimmy Reece) pulled away, and inadvertently escaped the pace car. The three cars were alone, and rather than wait for the grid to catch up, they rushed around to catch up to the back of the field.
Sam Hanks pulled the pace car off the track and into the pits, but chief starter Bill Vanderwater displayed the yellow flag to wave off the start. An extra pace lap was allowed, and the front row re-took their position at the front of the pack. By the time Hanks was ready to pull the pace car back out on the track, the field had re-formed, and Vanderwater gave them the green flag. At the start,
Dick Rathmann took the lead in turn 1,
Ed Elisian was second, and
Jimmy Reece third. As the cars battled into turn three, Elisian spun and took Rathmann to the outside wall, triggering a huge 15-car pileup. Reece braked and was hit from behind by
Pat O'Connor. O'Connor's car sailed fifty feet in the air, landed upside down and burst into flames. Several other cars spun to the wall and into the infield.
Jerry Unser touched wheels with
Paul Goldsmith, and flipped over the outside wall. Unser suffered a dislocated shoulder. Although O'Connor was incinerated in the accident, medical officials said that he was probably killed instantly from a fractured skull.
First half Jimmy Bryan escaped the opening lap crash, and came around to lead the first lap.
Eddie Sachs and
Tony Bettenhausen also got by unscathed, to run second and third. Due to the crash, the yellow light stayed on for 25 minutes (approximately 18 laps). Four of the top five starting positions were out of the race from the crash, including polesitter
Dick Rathmann, who placed 27th. After a lengthy cleanup, the green flag came back out around lap 19. Bryan, Sachs, Bettenhausen, and rookie
George Amick all traded time in the lead. There were 14 lead changes in the first half. The second yellow came out on lap 38 when
Chuck Weyant crashed in turn 4.
Eddie Sachs, a contender in the first quarter of the race, dropped out on lap 68 with transmission trouble.
Second half The second half of the race settled down to a battle between Jimmy Bryan and Johnny Boyd, with rookie George Amick also in contention. Boyd lost the lead during a pit stop on lap 126. Bryan's team had faster pit stops (three stops for 1 minute and 31 seconds), which allowed him to hold the lead. Rookie
A. J. Foyt spun out on lap 149. He hit an oil slick in turn one and went sideways, blowing out all four tires. The car did not make contact with the wall, but the engine stalled and Foyt was out of the race. He placed 16th. With 25 laps to go, Boyd was running about one second behind Bryan, with Amick (a lap down in third place) running between them. Boyd suddenly slowed on lap 177 with a worn out right rear tire, sending him to the pits, and elevating Amick to second. Bryan led the final 75 laps (139 total) en route to victory. Bryan was victorious in the same car in which
Sam Hanks won the 500 a
year earlier. Amick stayed within striking distance of Bryan for the last part of the race, but Amick's crew chief decided to accept a safe second-place rather than risk pushing their rookie driver into a mistake. During the race as the news of Pat O'Connor's death spread around the track, the mood among the spectators became somber and glum. Reportedly, some in attendance left the grounds upon hearing the news of the fatality, some never to return. ==Aftermath==
