Grand Forks Air Force Base firemen use the Jaws of Life to cut through the door of a simulated crash victim’s vehicle during a demonstration on May 22, 2014, on Grand Forks Air Force Base, N.D. The demonstration was one of several Wingman Day events designed to show how driving under influence can negatively affect people’s lives and property.
