Staff Sgt. James Sullivan, a 726th Air Mobility Squadron C-17A Globemaster III crew chief, ensures a valve is closed on a liquid oxygen servicing cart prior to repositioning it next to a C-17A Globemaster III on Ramstein Air Base, Germany, Feb. 26, 2025. Liquid oxygen is an extremely cold substance, boiling at -297 degrees Fahrenheit, and must be handled with extreme care. Liquid oxygen has many applications onboard aircraft such as breathing oxygen for aircrew and passengers in emergency situations, High Altitude Low Opening operations, and Aeromedical Evacuation purposes.
