Introduction

The Army Air Forces (AAF) relied on many types of medical support in World War II. One of the greatest medical contributions was research and development of personal survival gear and equipment for fighter and bomber crews. AAF doctors, for example, helped design the first flying suits that countered the physiological effects of the excess gravity forces (g-forces) in high-speed maneuvers. Aided by the U.S. Navy and organizations in Allied countries, the AAF Aeromedical Laboratory at Wright Field, Ohio, developed the first clothing designed successfully to counteract the negative effects of g-forces. Early in 1944, U.S. crewmen began to use the G-suits in Europe. G-suits were tactically valuable because they helped fighter pilots maintain consciousness under high gravitational forces. One P–51 pilot, who was credited with shooting down five enemy planes on one sortie, wrote:

I found myself all alone in the middle of a bunch of Jerrys. Having no one to keep Jerry off my tail I had to keep full throttle and keep my air speed sufficient so that I could break away from anyone coming up on my tail. This maneuver would normally black me out but my G-suit kept me fully conscious of what was going on. I followed Jerry down to the deck, picking up an air speed of 600 mph. The Jerry went straight in without pulling out, and I would have, too, if I had not been wearing my G-suit.

Because of the special needs of such pilots and crewmen, the AAF during World War II often required and obtained its own support services, separate from those of the ground forces of the U.S. Army. Early in the war, the commander of the AAF, Gen. Henry H. “Hap” Arnold, decided to try to obtain his own system of AAF medical support. By war’s end, AAF Air Surgeon Maj. Gen. David N. W. Grant had forged a medical service that was largely autonomous, although still subject to the authority of the Army Medical Department.

Two other notable AAF medical leaders were Malcolm Grow and Harry Armstrong, who directed the AAF medical program that helped aircrews cope with many new challenges in Europe. Grant, Grow, and Armstrong were the best of a highly educated group of AAF medical professionals, many of whom volunteered to leave private practice to cope with new aeromedical challenges in distant theaters of war. On the home front, the AAF also administered a large network of hospitals and convalescent centers, and its programs in medical research, development, and training prevented many deaths, wounds, and illnesses in combat theaters. By the end of the war, the AAF had laid a foundation for the independent Air Force Medical Service created in July 1949.
