Aeromedical Airmen gather around iStan, a realistic patient simulator, as part of pre-mission briefing during a simulated flight on a static C-130 Hercules trainer at Will Rogers Air National Guard Base, April 7, 2017. The flight was part of the Multiple Aircraft Training Opportunity Program, or MATOP, that brought eight of the nine Air National Guard aeromedical evacuation squadrons and the three aircraft they most commonly fly on to one place for realistic and comprehensive training, April 6-9, 2017.
