Eight years before the 9/11 attacks, Kuwati Ramzi Yousef with the help of a group of conspirators detonated a more than 1,000 lb car bomb on Feb. 26, 1993 in the parking garage of the North Tower. The explosion killed six people and injured 1,042 and the blast crater measured 130 feet wide and 150 long. The blast released a significant amount of smoke up the North Tower, but the damage was fixed and was not a major concern to the building's infrastructure.
