Ten people in the grandstands were injured, including three who were taken to a hospital for evaluation of cuts and other injuries. Seven people were treated at the speedway for minor scrapes.
"They're going to have to disassemble that thing and take it down," Busch said about the cable after it struck his car. "They're going to have to throw the red [flag] here."
Fox Sports released a statement about the incident.
"At this time, we do not have a cause for the failure of the camera drive line that interrupted tonight's Coca-Cola 600 at Charlotte Motor Speedway, and our immediate concern is with the injured fans," the statement read. "The camera system consists of three ropes -- a drive rope which moves the camera back and forth, and two guide ropes on either side. The drive rope failed near the Turn 1 connection and fell to the track. The camera itself did not come down because guide ropes acted as designed. A full investigation is planned, and use of the camera is suspended indefinitely.
"This camera system had been used successfully at this year's Daytona 500, last week's NASCAR Sprint All-Star Race and other major events around the world. We certainly regret that the system failure affected tonight's event, we apologize to the racers whose cars were damaged, and our immediate concern is for the race fans. We also offer a sincere 'thank you' to the staff at CMS for attending to the injuries and keeping us informed on this developing situation.
"When we have more information on the cause of the equipment failure, we will share it with you immediately."
Kyle Busch was unable to finish the race when his engine failed after the halfway point.
