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.

The South Korean authorities have extended the closure of a south-western airport where a Jeju Air plane crashed and killed 179 people on board, the Ministry of Land, Infrastructure and Transport said on Jan.

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.
