  • It is impossible for the building to lean like that and continue to 'pancake' or crush the floors beneath , because of the 47 core columns. And why would the top part of the building not continue to lean and fall over? The commission report says that the towers fell in 10 seconds (page 305). They had a long time to write it. Free-fall is 9.2 seconds. How could a 110 storey building 'collapse' thru the path of MOST resistance ALL the way down, even when leaning over. Over 10 floors a second?
