The missing data deepens the puzzle of what caused the deadly air disaster in Muan, South Korea, late last month.

SEOUL (Reuters) -South Korea plans to improve the structures housing the antenna that guide landings at its airports this year following December's fatal crash of a Jeju Air plane, which skidded off the runway and burst into flames after hitting such a structure.

After a Jeju Air plane crash-landed in southwestern South Korea in December 2024, killing all but two of the 181 people on board, a clip was shared in social media posts that falsely claimed it showed footage from inside the passenger cabin before the crash.

South Korea’s leading low-cost carrier, heavy with debt and its stock already near record lows, is now facing intense public and government scrutiny.

The black boxes holding the flight data and cockpit voice recorders for the crashed Jeju Air flight that left 179 people dead stopped recording four minutes before the disaster, South Korea's transport ministry said Saturday.
