Okay. For example.
With reference to the NIST computer simulations;
The NIST WTC Report claims that the less severe case “did not meet two key observables:
(1) no aircraft debris was calculated to exit the side opposite to impact and most of the debris was stopped prior to reaching that side, in contradiction to what was observed in photographs and videos of the impact event (see Section 7.10).
(2) the fire-structural and collapse initiation analyses of the damaged towers (NIST NCSTAR 1-6) indicated that the towers would not have collapsed had the less severe damage results been used.” (NCSTAR 1-2, p.167).
However, neither “key observable” is a scientifically valid reason for excluding the less severe case, as demonstrated in detail below.
The first “key observable” that the less severe case did not match is that “no aircraft debris was calculated to exit the side opposite to impact and most debris was stopped prior to reaching that side.”
Of the several pages that discuss the computer simulated damages caused by the less severe cases, the only sentence that addresses the
issue of exiting debris says this (referring to WTC 1): “Little or no debris penetration of the south wall of the tower was expected for the less severe impact condition.” (NCSTAR 1-2B, p.285)
Additionally, in section 9.11, “COMPARISON WITH OBSERVABLES”, the WTC Report states: “In the less severe damage analysis, as shown in Figure 9-120, none of the aircraft debris that passed through the core was calculated to exit the building.” (NCSTAR 1-2B, p.340).
Thus, it would initially appear that the first “key observable” was indeed absent from the less severe damage analysis.
However, elsewhere in the WTC Report, the reader finds that neither the base case nor the more severe case matched this “key observable” in either tower. For WTC 1, the WTC Report states: “No portion of the landing gear was observed to exit the tower in the simulations, but rather was stopped inside, or just outside, of the core.” (NCSTAR 1-2B, p.345)
This statement stands in stark contrast to the WTC Report’s admission that landing gear was observed exiting the south side of WTC 1 at about 105 mph. (NCSTAR 1-2B, p.344).
Therefore, if none of the simulations showed landing gear exiting WTC1, the justification for excluding the less severe case (ie. that the first “key
observable” was not present) is clearly false with regards to WTC 1.
There's lots more but it's easier if you just read the paper yourself.
