I thought those fuel bladders were pretty cool! Never thought about transporting volatiles in anything other than a rigid tank. Also had to look up what AN-8 Fuel is:
"AN8 is a special fuel blend unique to the Antarctic and Arctic. It has a lower flash point of 100 degrees Fahrenheit, which also lowers the gelling point when extreme cold temperatures can cause wax crystals to start forming in the fuel. AN8 will remain liquid until about minus 72 degrees."
