Twenty-three-year-old U.S. Airman Spencer Stone didn’t have to think; his answer was immediate and instinctive. Spencer and his friends, Aleksander Skarlatos and Anthony Sadler, charged and subdued the well-armed gunman whom was under a terrorist watch for suspected ties with ISIS.

During the skirmish, Spencer was injured, but still he saved another wounded passenger’s life. For his heroism, Spencer received a Purple Heart, and French President Francois Hollande presented the trio with France’s esteemed Legion of Honor.

Of Spencer and his friends President Obama said, “It’s these kinds of young people that made me extraordinarily optimistic and hopeful about our future.”

Spencer speaks about his experience while inspiring students to take action and make a positive difference in the world.
