While there have been several plane crashes involving Korean airlines throughout history, one of the most notable is the Korean Air Flight 801 crash in 1997. The Boeing 747-300, carrying 254 people, crashed on approach to Antonio B. Won Pat International Airport in Guam due to pilot error compounded by a malfunctioning instrument landing system. The accident resulted in 229 fatalities, making it the deadliest aviation disaster involving a South Korean airline at the time. The crash highlighted the importance of proper crew resource management and the need for accurate and reliable navigational aids in aviation safety.
