A New NIST FAQ

Most likely in response to being asked the same inane questions repeatedly by truthers, the National Institute of Standards and Technology has posted a supplental FAQ on their website. Not that this will change the fact that they will still be repeatedly asked the same inane questions.

Since the release of the Final Report on the Collapse of the World Trade Center Towers in October 2005, NIST has received many questions from interested readers curious about NIST’s findings and the technical basis for them. The complexity of the investigation and the length of the final report (including all of the supporting volumes) have made understanding of the investigation a challenge for many interested readers. In response, NIST has prepared simplified answers to the most frequently asked questions.

1. Was there enough gravitational energy present in the World Trade Center Towers to cause the collapse of the intact floors below the impact floors? Why was the collapse of WTC 1 and 2 not arrested by the intact structure below the floors where columns first began to buckle?

Yes, there was more than enough gravitational load to cause the collapse of the floors below the level of collapse initiation in both WTC Towers. The vertical capacity of the connections supporting an intact floor below the level of collapse was adequate to carry the load of 11 additional floors if the load was applied gradually and 6 additional floors if the load was applied suddenly (as was the case). Since the number of floors above the approximate floor of collapse initiation exceeded six in each WTC Tower (12 and 29 floors, respectively), the floors below the level of collapse initiation were unable to resist the suddenly applied gravitational load from the upper floors of the buildings. Details of this finding are provided below:
