April 12, 1999
Charlotte, NC - Last Friday, April 9 the Thunder Road roller coaster that had been closed for an investigation into what caused the accident, which injured seven people, reopened.
According to a report it was determined that the accident was caused by a partial break failure. The investigation revealed that one of the brake sensors failed, which allowed the incoming train to collide with the other one parked in the station.
To correct the problem all of the sensors on the roller coaster were replaced with new ones. In addition, the park decided to install a second sensor as a back up.
