A plane crashed at a Tehachapi Airport Saturday afternoon.
Investigators say the 2-seater glider was being towed by another plane, when for some reason the cable was cut loose, and the plane's wing hit the ground.
Crews say the plane cart-wheeled down the runway, damaging the plane's tail.
A 40-year-old pilot and nine-year-old were on board.
The boy was taken to a local hospital after complaining of pain. The pilot was not injured.
Crews are investigating the cause of the accident.
