 Charlie Kimball, who was running the high line, had no time to react to Aleshin's car that was sliding up the track before him and he slammed into Aleshin at almost full speed.The impact sent both cars into the outside retaining wall where the upwards momentum of Aleshin's out of control car caused it to vault up and over Kimball and the nose speared through the catch fencing, causing it to pirouette against the fence.Aleshin's car then fell back onto the track as pieces of the car were scattered for yards and a large section of the catch fencing was ripped down.
