On September 12, 2001, Peter Jennings interviews Marlene Cruz, a carpenter injured in one of the pre-collapse explosions in the WTC-sub-basement level B long before the planes hit the towers.
She was the first casualty of 9/11 admitted at Bellevue Hospital.
Cruz is a living witness whose testimony proves that pre-planted explosives were used to weaken the foundations of the towers as part of a well-planned controlled demolition.
When a controlled demolition implosion is being carried out on tall buildings, there are often strategic pre-collapse explosions to weaken and fracture the basement sub-structure; effectively creating a cavity into which the building contents will fall.
This was essential for the WTC twin towers because of the 110 stories worth of debris that came crashing down. The resulting demolition pile was so minimal because the volume of the upper floors were thrown into the deep basements below.
Despite hundreds of eyewitness reports of explosions throughout the Twin Towers by doomed victims, survivors, emergency service personnel, reporters, and bystanders, the 9/11 Commission Report contains virtually no mention of them and entirely ignores them in its conclusions.
