Twenty-five years after the Sept. 11 attacks, current and former Associated Press journalists who witnessed them recall the day. Reporter Karen Matthews was holding her 3-year-old daughter while pulling out a notebook as people around her asked, “What did you see?” Photographer Richard Drew captured the image that became known as “The Falling Man.” Journalist Larry Neumeister watched hospital workers prepare wheelchairs for thousands of patients who never came. Photographer Amy Sancetta remembers office paper floating through the sky “like birds.” Cameraman Jeremy Brown recalls hearing his father's voice amid the din of destruction. Their memories show what it was like to document a historic tragedy while living through it themselves.
