He told CBS News' Kris Van Cleave it was about 15 seconds of sheer terror.

"You know I have four children, none of them have even gone to college yet. I can't afford to die, all right, I gotta be here," he said. "I'm just glad that ultimately everybody was okay."

A pilot announced over the plane's public address system that air traffic controllers made an "administrative mistake," Observer columnist Scott Fowler wrote.

University of Georgia head basketball coach Mark Fox tweeted after the incident that the "pilot was terrific in the clutch."
