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 has vowed thorough investigations to find what caused a plane crash that killed 179 people, saying Monday that it will also inspect all Boeing 737-800 aircraft operated by the country’s airlines.

Shares of Boeing fell in early trading on Monday, one day after a Boeing model 737-800 was involved in the Jeju Air plane crash in South Korea that killed scores of passengers. The slide came hours after South Korea's transportation ministry announced it would investigate the crash and conduct a full inspection of all Boeing 737-800 aircraft in use in South Korea.
