The crash that killed two-time Indianapolis 500 winner Dan Wheldon was a “perfect storm” of events, many of them unforeseeable, a 60-page report from Indy said.
In the crash, Wheldon’s car was launched airborne and his head ultimately hit a vertical post on the catchfence — an “non-survivable injury.”
According to the report, safety systems functioned normally and there were no mechanical problems detected among the cars that might have triggered the chain reaction.
“While several factors coincided to produce a perfect storm none of them can be singled out as the sole cause of the accident,” IndyCar chief executive Randy Bernard said on a conference call.
“For this reason it is impossible to determine with certainty that the result would have been any different if one or more of the factors did not exist.”
In the wake of the 15-car wreck, many criticized CEO Randy Bernard and IndyCar for creating a deadly mix of circumstances – offering a jobless Wheldon the chance to earn a $US5 million bonus if he could drive from the back of a 34-car field to win the race on a high-banked oval.
