This Saturday marks the 20th anniversary of the attacks of September 11, 2001. Al Qaeda terrorists hijacked four commercial aircraft in the United States. Two crashed into the Twin Towers in New York, the third into the Pentagon, and the fourth fell in a field in Pennsylvania after crew and passengers confronted the hijackers in the aircraft’s cabin. In total, 2,977 people were left dead or missing. The images of the attacks, broadcast live around the world on television, helped make them one of the great events of the century. In this video we collect them to make a chronological account of that morning, from the impacts of the planes to the collapse of the World Trade Center, passing through the trapped people who jumped from the highest floors of the towers.
