On July 23, 1983, Air Canada Flight 143, a Boeing 767, ran out of fuel mid-flight due to a combination of technical issues and human errors, resulting in a successful emergency landing at Gimli Airport. The pilots' expertise and quick thinking were crucial in saving the lives of all 69 people on board. The incident was later attributed to a conversion error between metric and imperial units, which led to an incorrect fuel calculation. The successful landing was a remarkable feat of airmanship, considering the plane's lack of fuel and functional engines.
