South Korea's government said on Monday it will extend the shutdown of Muan International Airport by a week to Jan. 14, citing the ongoing investigation into the crash of a Jeju Air jet that killed 179 passengers on board.

The flight, operated by Jeju Air, was landing when it went off the runway in Muan, in the country’s southwest. Only two people survived the crash.

In his own words, a restaurant owner described recording videos of the Jeju Air plane crash as it happened. “Every time I closed my eyes, I kept seeing afterimages of the blast.”

South Korean officials are struggling to determine what caused a deadly plane crash that killed nearly 180 people on board, with the nation saddened, shocked and ashamed over the country’s worst aviation disaster in decades.

Investigators from the NTSB and Boeing were expected to join the investigation into South Korea's deadliest air crash.

Sunday's crash, the nation's deadliest aviation disaster in decades, has sent a shock wave through South Korean society, which is already facing a political crisis that led to the successive impeachments of the country's top two officials — President Yoon Suk Yeol and Prime Minister Han Duk-soo.
