　　The Hump Course

　　The "Hump Course" was a major air passage operated by China and the USA for combat against Japanese invaders between April 1942 and November 1945. With significant contributions in preventing Japanese incursions, it began in Assam of India and stretched to the Yunnan and Sichuan Provinces of China. With a total length of 500 miles, it was used to transport both the Chinese expedition army overseas and materials such as gasoline and equipment to China. At an average altitude of roughly 4500-5500m (maximum of 7000m), this airway spanned the Himalayas, Gaoligong and Hengduan Mountains, and the Salween, Nujiang, Lantsang, Jinsha, and Lijiang Rivers. Due to hostile flight conditions, it is considered the world’s most dangerous airway and saw many tragedies. It is known to have the longest flight duration, the toughest conditions, and the greatest cost in the history of air transportation.
