World Trade Center Attacks 1 + 2

The answer to all the 9/11 conspiracy talk lies within the plan for the first attack. The original plan was to damage the structure of one building to bring both of the towers down.

In the World Trade Center bombing (February 26, 1993) a car bomb was detonated by Arab Islamist terrorists in the underground parking garage below Tower One of the World Trade Center in New York City. The 1,500-lb (680Kg) urea nitrate-fuel oil device killed six and injured 1,042 people. It was intended to devastate the foundation of the North Tower, causing it to collapse onto its twin.

The attack was planned by a group of conspirators including Ramzi Yousef, Sheik Omar Abdel-Rahman, El Sayyid Nosair, Mahmud Abouhalima, Mohammad Salameh, Nidal Ayyad, Ahmad Ajaj, and Abdul Rahman Yasin. They received financing from al-Qaeda member Khaled Shaikh Mohammed, Yousef's uncle.

The bomb exploded in the underground garage at 12:17 P.M., generating a pressure estimated over one GPa and opening a 30-meter-wide hole through four sublevels of concrete. The detonation velocity of this bomb was about 15,000 ft/s (4.5 km/s). The cyanide gas generated is assumed to have burned in the explosion.

In October 1995, the militant Islamist and blind cleric Sheik Omar Abdel-Rahman, was sentenced to life imprisonment for masterminding the bombing. In 1998, Ramzi Yousef was convicted of "seditious conspiracy" to bomb the towers. In all, ten militant Islamist conspirators were convicted for their part in the bombing, each receiving prison sentences of a maximum of 240 years.
