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.

Search operations at the site of the Jeju Air plane crash concluded on Saturday, one week after the devastating accident claimed 179 lives. Officials announced that all 179 bodies have been recovered, with 151 already returned to their families along with identified personal belongings.

South Korea’s leading low-cost carrier, heavy with debt and its stock already near record lows, is now facing intense public and government scrutiny.

After the deadly Jeju Air crash in South Korea this week killed 179 people, the South Korean government said that it would be inspecting every domestic model of the plane involved, the Boeing (BA) 737-800.

As investigators look into what caused Jeju Air Flight 7C2216 to crash, the airline has come under intense government and public scrutiny for how it operates. Some of its operational practices are being challenged, including how it flew its planes more frequently than competitors and how it outsourced its maintenance overseas.

South Korean investigators said Friday they expected to find more human remains as they began lifting the wreckage of the Jeju Air jet that crashed on landing last weekend killing all but two of the 181 passengers and crew aboard.
