The one thought that entered Bill’s mind was that his controls might lock in place. If that happened, he would have to follow the course which the airplane took. Once more Bill shoved slightly with his left foot and the plane responded. He held the foot in place with a view of making a wide circle to get back to the landing field. He realized that the circle with such a small amount of rudder would be a very large one, but he could not take any chances of having the controls lock and the movement of the plane thus be limited to a small circle.
