Members of the 43rd and 375th Aeromedical Evacuation Squadrons carry a simulated Ebola patient onto a C-17 Globemaster III during a Transport Isolation System training exercise at Joint Base Charleston, S.C., Oct. 23, 2019. The TIS is a device used to transport Ebola patients, either by C-17 Globemaster III or C-130 Hercules aircraft, while preventing the spread of disease to medical personnel and aircrews until the patient can get to one of three designated hospitals in the United States that can treat Ebola patients.
