Narrative:
Was training student unusual attitude recovery techniques. Student was looking down at their knees; I was flying the aircraft at a level altitude banking left and right +/- 20 degrees. On last turn to right at 25 degrees with the airspeed about 120 KIAS indicated with nose falling through the horizon into a descent; the left side of the forward canopy popped open about 1 inch. Airspeed had increased at this time to about 130 KIAS and bank was about 30 degrees to the right.I maneuvered the aircraft to straight and level flight slowing down to 90 KIAS. I then made a precautionary landing at the closest airport. After shutdown; it was noticed that the latch cable was no longer able to secure the left hand side of the forward canopy.
