A South Korean passenger plane that crashed last month, killing 179 people, had air recorder data stop recording four minutes before the disaster. The cause of this anomaly is being investigated by the transport ministry. Analysts have raised concerns about a possible power cut affecting the recorders. The missing data has left many questions unanswered, including the potential role of bird strikes or weather conditions in the crash. The investigation also focuses on why the Boeing 737-800 did not deploy its landing gear before impact.
