 I'm technical sergeant Scott Simon, non-commissioner officer in charge, 4th or 3rd wing fuels management flight. The aircraft for 4th or 3rd wing C-130J model use liquid oxygen to enable to pilots and crew to breathe a high altitude. At fuels management flight, we receive, store and issue aviation fuel and liquid oxygen. To get the liquid oxygen from our storage tanks to the aircraft, we fill mobile service and carts to be installed in the aircraft. While handling liquid oxygen, we wear protective equipment, which consists of coveralls, face shield, goggles and heavy gloves to protect us from the sub-zero temperatures of liquid oxygen. People always notice the aircraft, but it's the fuel and the liquid oxygen that fuels management provides that enable it to do its mission, and I take great pride in that.
