Oklahoma Air National Guard aircrews assigned to the 137th Aeromedical Evacuation Squadron out of Will Rogers Air National Guard Base in Oklahoma City prepare litter patients to be loaded onto a Texas Air National Guard C-130 Hercules assigned to the 136th Airlift Wing out of Carswell, Texas, before taking off toward the U.S. Virgin Island of St. Croix from Will Rogers during a training mission, Aug. 21, 2019. The four-day event — which included two seven-hour flights to and from St. Croix, a four-hour ground training and evaluation meeting the second day, and a two-hour low- level flight the third day — was largely driven by an overhaul of career field-wide aeromedical evacuation training and evaluation standards.
