After overcoming pariah status at the end of the last century, South Korea must learn what caused the catastrophe on Dec. 29 and what lessons to draw from it.

South Korea plans to review the concrete walls positioned just beyond the end of some airport runways after an aircraft attempting an emergency landing smashed into one just over a week ago, killing almost everyone on board.

Two people, both flight attendants, are the only survivors of the crash and are being treated at South Korean hospitals.
