China Airlines Flight 611

China Airlines Flight 611 was a regularly scheduled international passenger flight from Chiang Kai-shek International Airport (now Taoyuan International Airport) in Taiwan to Hong Kong International Airport that disintegrated midair and crashed into the Taiwan Strait, 23 nautical miles (43 km; 26 mi) northeast of the Penghu Islands, 20 minutes after takeoff, killing all 225 people on board. The in-flight breakup was caused by metal fatigue cracks from a tail strike at Kai Tak Airport on 7 of February 1980 after which the aircraft was not properly repaired according to Boeing policies and manuals.
