South Korean investigators have shared their first findings on last month’s tragic Jeju Air crash, marking the deadliest air disaster in the country’s history. The preliminary report, submitted to international aviation authorities, sheds light on possible causes, including a bird strike and issues with the runway’s landing guidance system.

The Boeing 737-800, flying from Bangkok, overshot the runway during an emergency landing at Muan International Airport on December 29. The crash killed 179 people, leaving only two survivors. The plane collided with a reinforced concrete structure supporting the airport’s localizer antenna, which helps guide planes during landing. Experts believe this structure played a significant role in the tragedy.

Initial findings suggest that the pilots spotted a flock of birds during their final approach and declared an emergency due to a bird strike. Investigators found feathers and bird blood on both engines, confirming the incident. However, the exact timing of the strike remains unclear.

The report also mentions that the plane’s black boxes stopped recording just moments before the crash. At that time, the aircraft was flying at 161 knots (185 mph) and was 498 feet above the ground.

South Korean officials are working tirelessly to uncover the full cause of the crash. While the preliminary report offers some insights, the investigation is far from over. The final findings are expected within the next year.

This heartbreaking event has sparked renewed conversations about aviation safety and the need for thorough investigations to prevent future tragedies.
