Police were reviewing video footage Monday of a weekend sprint car crash that killed a
28-year-old driver at a western Sydney track, the associated press reported.
Scott Darley was driving one of the front cars in a 21-lap qualifying race Saturday when his sprint car veered off the track and became airborne before landing on its side and crashing into a concrete wall.
Darley, from western Sydney, was trapped in the car and freed by firefighters, but died at the scene. All other racing was suspended for the night.
Race officials said they were investigating the possibility that the throttle on Darley's car may have become stuck in the open position, leaving him no control of the speed of the vehicle as it entered a turn.
