S Korea police raid transport ministry as questions mount over Jeju Air crash

South Korean police have raided the headquarters of the transport ministry as questions mount over the authorities' handling of the country's deadliest aviation disaster.

Jeju Air Flight 2216 hit a concrete structure after overshooting the runway at Muan International Airport on 29 December 2024, killing all but two of 181 people on board.

Initial investigations found that the Boeing 737-800 had encountered a bird strike and that the concrete mound exacerbated the casualties.

The incident has since triggered multiple probes, with the latest one ordered by President Lee Jae Myung on Thursday after investigators recently discovered more body parts and victims' belongings.

On Friday police searched the ministry's office in the central city of Sejong for fresh leads on the cause of the crash and whether officials handled it properly, Yonhap news agency reported.

The raid was linked to the main government investigation into the crash. The results are due to be announced by the middle of this year.

But other parallel investigations have also been launched by various agencies and parliament.

In recent months, investigators discovered body parts and victims' belongings that had been put in sacks and stored alongside sacks of rubble collected from the accident site.

The victims' families had been requesting a re-examination of the rubble removed from the site for months.

The latest discovery triggered public anger and prompted Lee to order an inquiry as to why the remains and belongings had not been detected earlier.

Lee also ordered disciplinary action against those responsible for delays in the recovery of human remains.

The Ministry of Land, Infrastructure and Transport has apologised but the victims' families have refused to accept it.

"We are appalled by the transport ministry's late and inadequate apology, which the families say is like killing the victims a second time," a representative for the families said.

Earlier this week, a separate inquiry by the audit board found that the concrete mound was built to cut costs.

Muan International Airport was built on sloping terrain. Instead of flattening the ground to install an antenna system for navigation - which would have cost more - authorities built the system into a concrete structure that is elevated from the runway.

The Board of Audit said structures that house the antenna system known as localisers should be designed to break easily upon impact by aircraft.

Simulations have shown that all 181 on board could have survived had the plane not hit the concrete mound, causing it to explode into a fireball.

After a flock of migratory ducks hit the plane's engine, the pilots were able to land the plane on its belly and slide it down the runway - until it hit the concrete structure.

One month after the crash, aviation authorities removed similar concrete structures for navigation in seven airports.
