Abstract
Serum levels of cortisol and testosterone were measured in 39 USA Air Force personnel on active duty flying status. The subjects selected belonged to one of the following categories: pilot of a fighter-type aircraft, nonpilot on a fighter plane, pilot of a cargo-type aircraft or nonpilot on a cargo plane. Blood samples were taken prior to and after a routine flying mission. Coritsol levels prior to the flight did not differ across groups. Postflight samples of cortisol were elevated in the nonpilots, in comparison to the pilots, regardless of aircraft type. While testosterone levels were unaffected by crew position, the men flying on fighter-type planes had lower serum levels than did those on cargo planes. Hormone levels may be differentially affected by the stressors of routine military flight.
