One double crew was studied during four standardized transoceanic flying missions in C-5 aircraft during the first year of its use by the USAF Military Airlift Command. All four flights went from Delaware, U.S.A., to South Vietnam and back, and each included short stops in Alaska, Japan, and Okinawa. Urine specimens collected at 4-hour intervals were analyzed for epinephrine, norepinephrine, 17-hydroxycorticosteroids, potassium, sodium, urea, and creatinine. In general, the results confirm and extend the findings for a double crew which flew long-duration missions in C-141 aircraft, indicating that physiologic entrainment remains at all times the principal determinant of endocrine-metabolic responsiveness to factors in the flying environment, including the work itself. Recovery from these long missions (average duration = 65 hours) involved differential reversal among the flight-affected endocrine-metabolic functions. Extrapolations of postflight data suggest that the time for complete recovery exceeded the flight time. (Author)
