Landing long not confirmed, just suggested as a possibility.
The CBC's Cory O'Kelly reported from the scene that the plane came to rest nose down, just inside the fence at the airport perimeter. Debris from some of its parts was strewn behind it, and dozens of emergency vehicles were parked nearby.
Firefighter Eric Marshall said just before the plane went off the end of the runway, the pilot reported hitting the brakes, but was unable to stop. He said it's possible the plane landed too far down the runway or the pilot hit the brakes too late, given the runway conditions. It is believed the front wheel came off the plane, but the pilot managed to control the aircraft.
