Master Sgt. Randy Messineo, operation chief, Bravo Company, 1st Reconnaissance Battalion, and a native of Boston, salutes the crew of a C-130 Hercules as he jumps out of the aircraft 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. (Photo by Lance Cpl. Christopher J. Moore/Released)
