It was intended to kill thousands of people. Frankly, we were lucky in both attacks that the death toll wasn't much much higher.Yousef's complex 600 kilogram bomb was made of urea pellets, nitroglycerin, sulfuric acid, aluminum azide, magnesium azide, and bottled hydrogen. He added sodium cyanide to the mix as the vapors could go through the ventilation shafts and elevators of the towers. The van that Yousef used had four 6 m (20 ft) long fuses, all covered in surgical tubing. Yousef calculated that the fuse would trigger the bomb in twelve minutes after he would use a cheap cigarette lighter to light the fuse. He wanted to prevent smoke from escaping the towers, therefore, catching the public eye by poisoning people inside. He foresaw Tower One collapsing onto Tower Two after the blast would occur. The attack On February 26, 1993, a car bomb was planted by the Islamist terrorists in the underground garage below Tower One. The bomb's fuses burnt at a rate of one inch per two and one half seconds (1 cm/s). The men spent 300 United States dollars for the materials to build the bomb. The bomb exploded in the underground garage at 12:17 P.M., opening a 30 meter wide hole through 4 sublevels of concrete. The bomb generated a pressure of more than 1 GPa. The detonation velocity of this bomb was about 4.5 km/s (15,000 ft/s). The cyanide gas that Yousef put in the bomb burnt up in the explosion. Six people were killed : John DiGiovanni of Valley Stream, New York; Robert Kirkpatrick of Suffern, New York; Steve Knapp of New York City; Monica Smith of Seaford, New York; William Macko of Bayonne, New Jersey; and Wilfredo Mercado of Brooklyn, New York. At least 1,040 others were injured. However, the towers were not destroyed as Yousef envisioned. Yousef escaped to Pakistan several hours later. The bomb cut off the center's main electrical power line, and all telephone service for New York City. The bomb caused smoke to rise up to the 93rd floor of both towers, and cut off the towers' four stairwells and emergency lighting system. 216.239.59.104
