The investigation into the recent crash of a Jeju Air jet has uncovered significant evidence suggesting that bird strikes played a crucial role in the disaster. Preliminary reports indicate that bird feathers and remains were found in the engines of the aircraft, with DNA from ducks identified in both engines. The final four minutes of flight recordings are missing, complicating the investigation. Authorities are focusing on the potential collision with spectacled teals at Muan Airport, and several reports note bloodstains in the engines. In response to the tragedy, South Korea is moving to tighten airport safety regulations, including the removal of concrete barriers near runways. Despite the findings, the exact cause of the crash remains unclear, prompting calls for a thorough inquiry.
