On this 10th anniversary of the terrorist attacks of September 11, 2001, NENA mourns the loss of life that day in New York, Arlington, VA, and Stonycreek, PA. We honor the efforts of first responders and citizens alike who participated in the emergency response, allowing so many to return home that night when they themselves would not. Words cannot adequately express the debt of gratitude owed to these heroes who showed the world, in the face of unspeakable horror, the best that America and humanity have to offer. Today, we remember them, the familes they left behind, and all affected by this tragedy.
