An excellent reminder that there really are good reasons to do a
thorough preflight and to make sure the controls are free. This
happened just north of Winnipeg, and the aircraft was the first version
with PT-6-67 Turboprops. The Canadian DOT concluded that the control
locks were still locked when the aircraft took off.

Even without preflighting how do you miss the fact that the controls don't
move?
