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 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.

The deadliest accident in aviation history occurred in 1977, when two Boeing 747 jumbo jets collided on a foggy runway on the Spanish island of Tenerife, killing 583 of the 644 people on board the planes. Spanish investigators blamed the captain of the KLM 747 for taking off without clearance from air traffic controllers.

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.

Officials are investigating the cause of the deadliest aircraft crash in South Korean history, which killed 179 people.

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.

South Korean authorities have extended the closure of a southwestern airport where a Jeju Air plane crashed and killed 179 people onboard, the land ministry said Monday.
