South Korean police said they raided Muan airport and the Jeju Air office Thursday morning over the crash involving one of the carrier's Boeing 737-800s that killed 179 people.
Jeju Air flight 2216 was carrying 181 people from Thailand to South Korea on Sunday when it issued a mayday call and belly-landed before hitting a barrier and bursting into flames, killing everyone aboard except two flight attendants pulled from the burning wreckage.
