Canada's Sea King helicopter fleet grounded after accident

Canada’s tired fleet of Sea King helicopters has been grounded after one of the choppers toppled over at a Nova Scotia Air Force base with four people on board.
It is unknown whether the incident late Monday evening at 12 Wing Shearwater is related to the age of the helicopter. Investigators from the military’s Directorate of Flight Safety were called to determine what happened and whether the rest of the fleet could experience the same problem.
