Click on a box at the top of map to reveal what U.S. intelligence knew at a particular point in time. Then, roll over individual events and names for details. (You'll need the Flash 3 player or later and an 800x600 monitor to see the interactive Flash version.)
This interactive map, while not intended to be comprehensive, highlights what U.S. intelligence knew at particular points in time, beginning with the 1993 World Trade Center attack. (The capture of the plot's organizer, Ramzi Yousef, launched John O'Neill into his pursuit of Al Qaeda.)
Obviously, at the time pieces of information surfaced, much of it could not be fully understood and connected. Moreover, some clues simply weren't pursued and the CIA and FBI didn't always share information.
But this map does lay out some striking links between the 9/11 attack and Al Qaeda's previous plans, operatives, and conspiracies over the eight years leading up to 9/11.
Also explore a full timeline of Al Qaeda's global reach, with more details--such as the first time bin Laden's name became linked to suspected terrorists.
