The results of Project Cold Case, an investigation of the cold land survival capabilities of Air Force pilots wearing the Full Pressure High Altitude Flying Outfit (A/P22S-2 and A/P 22S-3) are presented in this report. Six subjects wearing these garments were placed under simulated survival conditions in a wooded area of interior Alaska near Fairbanks. Ambient air temperatures reached -30 F and were below -27 F for at least 50% of the time. On the third day air temperatures rose and remained at -10 F until the conclusion of the test. The test lasted for 72 hours. Two subjects wearing the Full Pressure Suit without additional clothing survived for 11 and 30 hours. At the end of this time they were fatigued and moderately hypothermic. Two subjects with the Full Pressure Suit plus a nine-piece down-filled survival outfit (Clothing Outfit, arctic survival) survived for 52 and 72 hours. The 52-hour survivor suffered a noncold injury which necessitated his removal. Two Subjects with the Full Pressure Suit plus an experimental ADC Walk-Around Sleeping Bag survived for 72 hours each.
