William M. Leary Jr.'s study combines history with personal drama to reconstruct an important chapter in the early years of aviation. He has conducted intensive research in American governmental archives, the Hoover Institution, and numerous libraries throughout the United States, in addition to obtaining access to the records of Pan American Airways (who bought out CNAC in 1933). His history of CNAC offers insights into the history of modern China and sheds light on several key aspects of Sino-American diplomatic and business relations.
