I was a passenger on Delta Air Lines flight 312, June 1, 2014, a Boeing 717-200, N934AT, when on departure out of KCAK en route KATL, we took a pretty violent turn to the left, and veered way off course of the departure heading for Newcomerstown VOR, CTW.
Went back to LiveATC archive (KCAK, June 1, 2014, 1500-1530Z) to find more about the situation and the attached audio I later edited.
Traffic was a Cessna 206, N245MC, 5miles out at 400'.
