Calculations, smalculations. You don't believe your own eyes, so why would calculations do anything?
I've already commented on this line, but I think it warrants further comment.
WTC Dust is presenting a classic example of a fallacy that I coined the term "Unevaluated inequality fallacy" to describe. She is claiming that the collapse times of the Twin Towers were greater than those that would be expected from a gravity-driven collapse. Mathematically, this can be expressed very simply as:
T1 > T2,
where T1 is the measured collapse time and T2 the predicted collapse time. In reality, we can't be certain of either T1 or T2, so we can assign ranges of T1' ± delta T1 and T2' ± delta T2 to both. From this we can therefore modify the claim to "The shortest possible calculated collapse time is greater than the longest possible measured collapse time", or:
T1' - delta T1 > T2' + delta T2
So the question to be addressed is, what are the values of T1', T2', delta T1 and delta T2?
I have offered values for these. The observed collapse times were in the range 12-16 seconds, and various calculations give times in the range 12-16 seconds. Therefore, we have T1'=T2'=14s, and delta T1 = delta T2 = 2s. Now, the problem for WTC Dust's claim is that, quite obviously:
T1' - delta T1 = 12 < 16 = T2' + delta T2
In fact, the centre values and the uncertainties are very well matched; the conclusion to be drawn is that the collapse time is exactly what we would expect, to within errors of measurement and calculation.
What is WTC Dust's response to this? It is to reject the calculations out of hand,
without substituting any values of her own. WTC Dust is claiming certain knowledge that an inequality is true despite
not knowing the values that are asserted to be unequal, and in effect claiming that some of these values are
unknowable. It's a variant on the bare assertion fallacy; the variation is that the claimant actually refuses to back up the claim, by claiming that
any attempt to back it up would be invalid. The pretence at support for the claim is therefore a further bare assertion which, if true,
would invalidate the original claim.
So, WTC Dust's claim that the WTC Twin Towers fell faster than they should have fallen must be rejected out of hand.
