The role of flight surgeons continued to mature and expand as the U.S. faced World War II. The 1941 movie Dive Bomber, although focused on Naval Aviation, highlighted the role of the flight surgeon just prior to the attack on Pearl Harbor, and demonstrated how solving the problems of hypoxia at altitude would reduce the aircraft mishap rate.

During World War II, the head of the U.S. Army Air Forces, General of the Army (later General of the Air Force) Henry 'Hap' Arnold, directed all flight surgeons in the Army Air Forces to fly regularly with their patients in order to better understand the aviation environment.
