Marine Corps Master Sgt. Randy Messineo, operation chief, Company B, 1st Reconnaissance Battalion, and a native of Boston, salutes the crew of a C-130 Hercules aircraft as he jumps out of it during a double-bag static line course held in Parker, Ariz., March 24, 2014. A static line is a cord attached from one end of the aircraft to the other. When the Marine jumps from the plane, the line pulls the deployment bag out of the pack on the Marine’s back causing the parachute to inflate. - Marine Corps Master Sgt.
