U.S. Air Force ramp service specialists with the 8th Expeditionary Air Mobility Squadron load a negatively pressurized CONEX onto a Qatari Emiri Air Force C-130 Hercules aircraft in preparation for a Qatar-U.S. Air Force Friendship Event at Al Udeid Airbase, March 9, 2021. Members of the 379th Expeditionary Aeromedical Evacuation Squadron showcased how the NPC enables caregivers to transport and treat infectious patients in a safe and self-contained environment. The NPC was developed in response to COVID-19 patient transport requirements. The negative pressure inside allows for air to leak into the NPC, rather than out, risking contamination of the aircraft.
