Korean Air Flight 801 (1997)
In 1997, when Korean Air Flight 801 attempted to land at Guam International Airport, it crashed, killing 228 people. This crash highlighted the importance of communication in the cockpit and why crew training is so important. Even though the captain was an experienced pilot with many awards, he made one dire mistake that ended up killing everyone. The pilot failed to brief the crew on his landing procedure and felt fatigued before flying. All of this combined caused a catastrophic event (Simple Flying).
