Jane D. Hartly, the U.S. ambassador to France, Airman 1st Class Spencer Stone and his two friends speak at a press conference in Paris on Aug. 23, 2015, following a foiled attack on a French train. Stone was on vacation with his childhood friends, Army Spc. Aleksander Skarlatos and Anthony Sadler, when an armed gunman entered their train carrying an assault rifle, a handgun and a box cutter. The three men, with the help of a British passenger, subdued the gunman after his rifle jammed. (U.S. Air Force photo/Tech. Sgt. Ryan Crane)
