South Korean investigators confirmed that both recorders stopped several minutes before the Jeju Air aircraft crashed at Muan International Airport.

The investigation into the deadliest air disaster on the country's soil remains ongoing, focusing on the role of bird strike and involving an analysis of the engines and the "localizer" landing guidance structure.
