At 12:18 p.m., the bomb exploded, killing six, creating a crater 150 feet in diameter that blew a hole five floors deep in the parking garage. The towers, however, did not fall.
Killed were John DiGiovanni, Robert Kirkpatrick, Stephen Knapp, William Macko, Wilfredo Mercado and Monica Smith.
Yousef, the mastermind of the plot, later said he had hoped to kill tens of thousands.
The explosives were manufactured at a Jersey City apartment, using chemicals ordered from a supply company. They were placed in the truck at a rented storage shed alongside three tanks of compressed hydrogen gas, purchased to enhance the destructive power of the explosives.
The plotters, including Yousef and Yasin, built the bombs using manuals brought from Pakistan."
