9/11: The North Tower & The 'Pile-Driver' That Wasn't
NIST claims that the top sections of the Twin Towers crushed down the bottom sections and made them collapse. But is this really plausible? In fact, did this "crushing" even happen at all?
Thanks to David Chandler for all his work, and for much of the footage used in this video. Thanks also to Architects & Engineers for 9/11 Truth and to 'Kostack Studio' and 'To The People' you tube channels for the animations of the collapse of WTC 1 and the structure of the Twin Towers.
The official explanation for the collapse of the Twin Towers is called the pile-driver theory (PDT). It states that the upper block of 12 floors began to fall when the plane and fire damaged floor gave way. This falling upper block then crushed all of the floors beneath it all the way to the grounds.
David Chandler, a high school physics teacher, shows some pictures of the building’s construction and goes through videos that show that this pile driver activity is NOT actually occurring. He explains how Newtons Third Law would cause the upper block to be crushed at the same rate as the lower block is being crushed by the upper. Review of the rate of fall, shows that the lower building is being cleared from beneath the upper block rapidly. (This implies explosives.) [He has other videos that show a wave of demolition moving down the building partially hidden –and partially visible– beneath the falling debris canopy.]
