During the Second World War, FDR promised thousands of tons of US material to Chiang Kai Shek in order to keep China in the war and keep Japan distracted. But how would the US get it there? The only land route had been cut off by the Japanese invasion, leaving only one other option: air.

For the next three years, US planes flew “The Hump”: an air route from Assam to Chongqing, over the dangerous Himalayan mountains and Burmese jungles. Countless planes were lost, whether on a Himalayan mountainside or deep in the jungle.

That tale is the subject of Skies of Thunder: The Deadly World War II Mission Over the Roof of the World (Viking: 2024), by Caroline Alexander, who joins us today.

Caroline Alexander is the author of the bestselling The Endurance: Shackleton’s Legendary Antarctic Expedition (Knopf: 1998), which has been translated into thirteen languages.
