Flight-stress appraisal was made by means of a battery of urinary determinations epinephrine, norepinephrine, 17-OHCS, urea, uric acid, phosphorus, magnesium, sodium, and potassium for flyers who participated in a 20-hour missions in C-130E aircraft flights from New Zealand to Antarctica, and back, b 6-day missions in C-135B aircraft earth-circling missions, or c 7-week missions in C-135B aircraft over-frequent transoceanic and transcontinental flying. The adrenal medulla as judged by urinary epinephrine consistently showed flight-sensitivity, but other endocrine- metabolic functions varied in ways indicative of adaptation. With flight circumstances standardized particularly with respect to time of day, flight effects tended to be reproducible. With crew rest limited to 2 days, recovery from flight-stress tended to be incomplete. Sleep deprivation and crew position were shown to be factors which modify flight-stress reactions. Eastbound and westbound earth-circling missions did not induce different degrees of flight- stress, as judged by these endocrine-metabolic indices.
