Does the Cessna 152 or 172 have emergency door cable releases? Is there such a thing as an emergency cable release inside the cockpit of 152 or 172, to remove the door hinge pins in an emergency?
The Cessna 150 Aerobat and 152 Aerobat both have jettisonable doors.

I don’t believe any version of the Cessna 172 does as there in no aerobatic C172 versions.

This Photo shows two “D” rings which are pulled to jettison the doors.
