: Serum and urine cortisol levels were measured in Navy pilots and their flight officers during aircraft carrier landing practice in the two-man F-4B jet aircraft. The pilots showed a considerable adrenal cortical stress response; the flight officers did not. The complex and dangerous task of carrier landing appears to be a greater stress on the pilot in control of the aircraft than on his passive partner. These findings suggest that in acute stress situations, assigned role and responsibility may become dominant factors in the hierarchy of psychoendocrine control of adrenal cortical responses.
