A person jumps from the north tower of New York's World Trade Center as smoke and fire billow from the building, Tuesday Sept. 11, 2001. Terrorists crashed two hijacked airliners into the World Trade Center and brought down the twin 110-story towers Tuesday morning. Many people jumped from the towers as they burned. A jetliner also slammed into the Pentagon in Washington.
