I'm no weather expert, but at -117 degrees (Fahrenheit, I assume), with only blankets and their uniforms, wouldn't the landing party be, well, dead? If they had the kind of clothing you'd wear in the Yukon or something, I could see them holding out. But to me the temperature seems very extreme. The guys would be in just as much danger of dying from exposure and hypothermia at much higher temperatures.
This crossed my mind as temperatures dipped into the single digits recently and I was fricking painfully cold in my non windy driveway all bundled up.
