New York: A Terrorist Target

There have been at least nine planned terror attacks here since Sept. 11, 2001. Those involved hoped variously to destroy the Brooklyn Bridge, to blow up financial institutions, to smuggle explosive materials into the city, to detonate explosives on the subway, to release cyanide into the subway system, to ignite an airport jet-fuel pipeline, and to collapse Path train tunnels at Ground Zero.
