A brief explanation of the relevance and consequences of NISTs failure to include these elements in their analysis of the WTC7 collapse. This is designed to be a brief introduction to the issue.
From the analysis above we can clearly see that NIST's hypothetical collapse scenario did not take into account relevant design details of World Trade Centre Building 7. Their improbable explanation on the issue of the initial failure, which was not substantiated via any hard evidence anyway, now becomes impossible.
Furthermore, NIST's failure to account for the freefall collapse of this building also shows the inadequacies of their WTC7 'investigation'.
