The 9/11 "truth" movement never mention them, why?
You need to take into account the testimonies of the 14 survivors in stairwell B of the North Tower 1 between floors 2 to 6 and Genelle Guzman (13th floor) and the "9/11 surfer", Pasquale Buzzelli that fell from the 22nd floor.
"When I looked up, there was nothing above me" - Pasquale Buzzelli
The Twin Towers - 110 stories, equal to 10 Titanics in weight, stacked on top of one another.
The survivors heard no loud explosions, no flashes of bright light, no molten steel raining on them, they did not go blind or deaf due to light flashes or explosions, they werent hit by falling debris and did not die years later due to radiation sickness.
They refer to hearing a RUMBLING, like a freight train coming at them and then - POOF the building is gone into a HUGE DUST cloud.
The seismic readings were that of a 20 and 16 story building hitting the ground respectively and on Sept 12 and 13, 2001 people were reporting on the LACK of rubble for 2 x 110 story buildings and the 22 story WTC3, the Marriot Hotel (13 survived in the little stump that was left)
