The Allies came back with a response unprecedented in scope and magnitude: They began to muster planes and pilots to fly over the world's highest mountain range. The route over the Himalayas from India to Yunnanyi, Kunming, and other locations in China was immediately dubbed "the Hump" by those who flew it.
General Tunner immediately increased to one year the time a pilot would remain in the theater. He also increased the number of flying hours to 750. "It didn't make the pilots happy," the General wrote later, "but . . . it kept quite a few of them alive."
