Human Factors
Pattern work on runway. Working on landings specifically the flare and touchdown. We came in a little faster than expected; flared and we were running out of pavement. I took controls from the student and commanded 'my plane!' He had his feet locked on brakes as he froze. I ordered him to take his feet off the brakes and that I was flying the plane. As a result of his feet being on the brakes with speed we started to veer. I had to restate that I had the controls and to take off his feet. All along we are running out of runway. We are going a little too quick to get off the runway onto the grass to avoid the fence and avoid flipping over. Go around was not an option; in my opinion at this point; route 50 and the obstacles ahead would have been an issue. I was committed to stop the plane by the end of the runway. Raised flaps to zero degrees; applied necessary braking and back pressure on controls to keep pressure off the nose wheel and better traction on main wheels. When I saw we were not going to make it; mixture to idle; fuel shutoff valve off and master off. After we hit the fence and stopped. Took the keys out and we walked away with our headsets.
C172 flight instructor reported taking control from his student during landing; but the student keeps his feet on the brakes. By the time the instructor has full control of the aircraft there is insufficient runway remaining to stop or go around and the aircraft goes into the fence at the end of the runway.
