South Korean investigators said Saturday they were close to finalising the transcript of the cockpit voice recorder from a fatal plane crash that left 179 people dead last week.

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.

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

A plane carrying 181 people crashed while landing, killing most on board. Officials were investigating a possible malfunction with the landing gear and a bird strike.

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.
