Master Sgt. Joshua Mal, a C-17A Globemaster III loadmaster assigned to the 3rd Airlift Squadron, keeps his head above water as Staff Sgt. Adam Ellerd, the 436th Operations Support Squadron Survival, Evasion, Resistance and Escape Operations NCO in charge, looks over his shoulder from a personal watercraft to see when and if Mal successfully releases from his harness July 17, 2015, near Dover Air Force Base, Del. Mal and other students had to find and release their torso harness fittings while being towed through the water to simulate being dragged by their canopy after landing in water.
