HURLBURT FIELD, Fla. -- Air Commandos with the 1st Special Operations Logistics Readiness Squadron collect samples of liquid oxygen and test the odor of each to ensure all oxygen delivered to 1st Special Operations Wing aircraft is safe for aircrew members. Liquid oxygen is stored at minus 297 degrees Fahrenheit in a 2,000 gallon tank, which is then transported to smaller carts and ultimately to 1st Special Operations Wing aircraft, enabling aircrew members to train for global operations.
