Two more airliners narrowly avoided disaster after a Jeju Airlines plane burst into a deadly fireball during a failed belly landing in South Korea Saturday.

Two additional flights nearly ended in tragedy over the weekend as South Korea grapples with its worst plane crash in decades.

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.
