A Northern Patrol Mission from 14 Wing Greenwood in Nova Scotia just barely got off the ground Thursday morning.
The pilot of the CP-140 Aurora aborted the flight before it was off the runway.
The military says the plane skidded of the tarmac and came to a stop in the grass around 11:15 a.m.
There were 17 crew members onboard but no one was hurt.
Investigators are trying to sort out what caused the aborted takeoff.
