The Jeju Air black boxes aboard a Boeing 737-800 that crashed at Muan International Airport (MWX) on December 29, 2024, failed to record the final minutes of flight data.  

According to the yonhap news agency, the flight data recorder (FDR) and cockpit voice recorder (CVR) from the jeju air Boeing 737 only captured data up until around four minutes before the plane collided with an airport embankment.  

South Korean authorities said efforts by the National Transportation Safety Board (NTSB) in the United States (Us) to locate the missing data had proven unsuccessful. 

It will now be down to accident investigators to determine the events that led to the crash despite not having this critical data.
