There were six deaths at WTC/93, but that fact obscures the reality that the sheik and Ramses Yousef were trying to kill 100,000 people that day. They had hoped to topple one building into the other and both onto lower Manhattan. Yousef said to the arresting FBI agent while in the helo bringing him to the MCC the the buildings would not be standing if he’d had more explosives and he was right.
That wasn’t the only plot the Blind Sheikh was involved in. He had laid out plans to bomb subway tunnels in NY, the UN [because of IRaq sanctions], and some other targets. that’s just here... there is the Luxor Massacre in Egypt, among other things. He issued orders to his followers from his prison cell with the help of a left wing American layer associated with the NLG, a communist party front.
His close associates were involved in the assassination of Afghan General Shah Ahmed Massood a few days before 9/11.
