China Airlines Flight 611 was a scheduled passenger flight operating between Taipei, Taiwan, and Hong Kong. On May 25, 2002, the Boeing 747-200B aircraft, carrying 225 passengers and crew, took off from Taoyuan International Airport without any reported issues. Tragically, less than 20 minutes into its flight, the aircraft experienced a sudden and catastrophic structural failure. Witnesses on the ground observed the plane beginning to break apart in mid-air, particularly the vertical tail section, which ultimately led to a loss of control and the subsequent crash into the Taiwan Strait. The wreckage was located approximately 21 kilometers from the coast of Taiwan.Following the disaster, a thorough investigation was initiated by the Taiwan Transportation Safety Board. It was determined that previous maintenance work, including repairs related to the plane's tail, had not been properly executed. This oversight compromised the structural integrity of the aircraft. The findings of the investigation underscored the critical importance of strict adherence to aircraft maintenance protocols. The crash prompted a global reevaluation of safety standards and operational guidelines within the aviation industry, with emphasis on preventing similar occurrences in the future.
