Remembering 9/11

Sept. 11, 2001 forever changed the U.S. when four passenger aircrafts were hijacked by al-Qaeda members and crashed into the World Trade Centers, the Pentagon and a field in Pennsylvania. In this special five-part 41 Files miniseries, digital producers Katharine Finnerty and Casey Murray go back to that day and examine its lasting impacts.
