On 24 August 1999, an explosion on board a landed Uni Air plane, Flight 873, injured 28 people and killed Ku Jing-chi (C: 古金池, P: Gǔ Jīnchí), the older brother of Ku Chin-shui.
A report from the Aviation Safety Council (ASC) stated that the cause of the fire was the interaction of two luggage items that happened to be in overhead compartments. Firstly, gasoline had leaked from a plastic bottle and, secondly, a motorcycle battery had been jostled, causing an electric arc that ignited fumes from the gasoline.
Prosecutors accused Ku Chin-shui of asking his nephew to take gasoline on the flight.[2] Ku was convicted and sentenced to ten years in prison. Upon appeal, the sentence was shortened to seven and a half years. After a fifth retrial, he was declared not guilty. The ASC had commissioned an analysis from the Chungshan Institute of Science and Technology, which said the ASC's simulation environment differed from that of the aircraft which had exploded."[2]
The court case caused Ku to lose his teaching position, and he worked part-time at a steel factory until 2008, when he returned to teaching full-time.[3]
