The 50th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Monday, May 30, 1966. The official program cover for the race celebrated both the 50th running of the race, and 150th anniversary of Indiana statehood.
Eleven of the 33 starters were eliminated in a first-lap accident right after receiving the green flag on the main stretch. Only A. J. Foyt was injured, hurting his hand scaling the catch fence trying to escape the wreck scene. Only seven cars, the fewest finishers ever, were still running by the end of the race. First-time starter Jackie Stewart led by over a lap late in the race in John Mecom's Lola T90-Ford.Kettlewell, p. 2192. However, inside ten laps to go, his oil pressure dropped too low due to a broken scavenge pump. Stewart parked the car, and after briefly attempting to push some ways, he walked back to the pits. Fellow first-time starter Graham Hill inherited the lead and led a total of 10 laps to win, the first rookie winner since 1927. Despite parking his car, Stewart was voted the rookie of the year over Hill, completing enough laps to finish in 6th place.
Defending race winner Jim Clark spun twice during the race, and finished second. A mild controversy developed at the conclusion of the race, as Clark's crew - and some observers - erroneously believed their car was the race winner over Hill. However, during post-race review, the scoring serials were settled later that evening, confirming Hill the race winner and Clark placing second. For the second year in a row, the Wood Brothers from the NASCAR Grand National circuit were invited to work pit stops, this time for Dan Gurney. However, the car dropped out of the race in the crash on the opening lap.The Talk of Gasoline Alley - 1070-AM WIBC, August 6, 2005

Race recap Start As the field came down the main stretch for the start, Billy Foster was among those jockeying for position. As the green flag fell, he nearly touched wheels with Gordon Johncock and lost control. He spun directly into the outside wall, just beyond the start/finish line, and triggered a huge pileup. Sixteen cars were involved, with debris and loose wheels bouncing all over the racing surface.
As the drivers instinctively scurried out of their machines to avoid possible flames (although no significant fires had broken out), A. J. Foyt became the only driver casualty of the incident. He injured his hand climbing over the catch fence on the outside of the track. He was checked out at the infield hospital, and cleared to drive relief if needed. One spectator was hit by a wheel from the crash.
Of the sixteen cars, eleven were damaged beyond repair. The red flag came out, and after the cleanup, the race lined up for a restart with only 22 cars. The red flag delay was about 1 hour and 24 minutes.
When the race was restarted, the field took several warm up laps, and restarted single file. The yellow light came back on almost immediately when Johnny Boyd crashed in turn 1 on the first green lap.
Race The early half of the race was dominated by Lloyd Ruby, who was seeking his first win in the Indianapolis 500. However, a bad pit stop resulted in Ruby losing a couple of laps and he went on to finish 11th. Jackie Stewart dominated the second half of the race, leading 40 laps. Stewart was leading by a little over a lap before he began to suffer from low oil pressure with ten laps to go. Stewart parked his car in turn four, and briefly attempted to push the car back to the pits. Eventually Stewart abandoned the machine, and walked back to the garage area.
Graham Hill inherited the lead, led the final ten laps, and won the race. His original margin of victory was 42 seconds over second place, Jim Clark, pending the final results.
Controversy over who won the race During the race, confusion broke out over the running order, which resulted in people being unsure, even to this day, on who won the race. The confusion in the scoring led to a controversy, wherein second place Jim Clark's team thought they were the rightful winner. Clark had spun on two separate occasions during the race, but did not make serious contact during either incident. He did not stall his engine either time, and was able to drive to the pits for the crew to inspect the car quickly both times. Clark's team contended that he did not lose a significant amount of track position, and estimated that they were still one lap ahead of Graham Hill at the finish. The scoring pylon, which was manually controlled and unofficial, changed frequently and somewhat sporadically as the scoring was ironed out, much to the dismay of Clark's crew in particular, and much to the confusion of spectators. The unofficial results at the conclusion of the race showed Graham Hill winning by 41.13 seconds over Clark. The morning after the race, USAC released the official results, and the standings were unchanged. Colin Chapman and Andy Granatelli, the entrants of Clark's Lotus team, declined to file an official protest. A possible explanation given was that the Lotus crew did not see Hill pass by Clark during the aftermath of the second spin.Saskatoon Star-Phoenix - Google News Archive Search
Race winner Graham Hill admitted to having an "uneventful race", being "puzzled" and "surprised" to be the winner, while other unsatisfied competitors quipped that he had "never passed a car all day long." The IMS Radio Network, which scored the race independently from the USAC officials, also came up with Hill as the first place car."The Talk of Gasoline Alley," Network Indiana, May 11, 2006 The apparent controversy died out quickly, and no official action was ever taken. Years later the subject is still mildly debated in racing circles. A theory emerged that scorers accidentally omitted one lap from Jim Clark's official tally. Therefore, he was effectively placed behind Hill at the finish. The car of Al Unser was painted nearly identical to that of Clark's. The theory is that when Al Unser crashed out of the race on lap 161, scorers mistakenly thought it was Clark, and as Clark drove by in the immediate aftermath, they credited that lap to Unser by mistake.
