Two truthers on their way to a Gage presentation are killed in an auto accident. Finding themselves at the Holy Gates, they ask St. Peter if God can confirm that 9/11 was an inside job. Peter calls God down, who explains to the truthers that it was simply 19 Al Quaida terrorists using hijacked planes.
One truther looks at the other and says " Can you believe it? This is even bigger than we thought! "

NIST (Page 39) say only fires brought WTC7 down, and debris from the collapsing tower's had nothing to do with the WTC7 collapse, yep, NIST said that!
Table 3–1. Comparison of global structural model predictions and observations for WTC 7, Case B.
a: From NIST NCSTAR 1-9, Appendix C and Chapter 8. b: Not available
The horizontal progression of buckling core columns was interior to the building and could not have been observed from the street. The process occurred over a longer duration of 10.3 s (13.5 s minus 3.2 s) for the analysis without debris impact damage than for the duration of 2.6 s (6.1 s minus 3.5 s) for the analysis with impact damage. In the analysis without debris impact damage, the lack of core framing damage on the lower west side resulted in a sequence of interior column failures from east to west that occurred at a more uniform rate. In the analysis with debris impact damage, the core framing damage on the west side resulted in a more rapid failure of the west interior columns in the last stages of the horizontal progression.
The initial downward movement of the north face from the northeast corner to the east side of the screenwall was observed at 6.9 s after the initial downward motion of the east penthouse. The LS-DYNA analyses with and without impact damage straddled that value.
