Late one night, a man in Slim Cornett's church was showing Slim around a county airport in rural Mississippi. "This switch lights up the runway," the man said as he flipped it. "Then, let's say there is a plane in distress up there. I would throw this switch and turn on the search lights."

As the night skies lit up, a small plane materialized out of the darkness and landed. Slim and his friend watched in amazement as Franklin Graham, son of the famous evangelist, stepped off the plane. The pilot had been flying Franklin back to school in Texas when the electrical system shut down, leaving them stranded in the Mississippi night without lights or radio or any means of guidance. From out of nowhere, the search beam had come on and guided them to the landing strip.

As Franklin's mother, Ruth, tells the story, earlier that evening before they left home, Billy Graham had prayed for the Father to protect and guide his son and the pilot.
