Within less than an hour, three hijacked aircraft had struck New York’s iconic Twin Towers and the Pentagon. But the nightmare was far from over.

Amid the devastation and fear, extraordinary acts of heroism emerged. Rescue workers, survivors and witnesses remember the tragedy and the moments that changed the world forever.
