Reply #89: But the NIST times that you are using are not the total collapse times. [View All]

They listed 9 seconds for the approx. time for the total collapse of WTC 2 for the South Tower. I have seen a range of times for the collapse. I would think it is perhaps more accurate to say that the South Tower, WTC 2, probably fell completely in about 10 seconds, rather than 9 seconds. But since I just grabbed that number off the NIST site I went with it. If that is indeed the actual total collapse time, 9 seconds, then indeed Tower 2 fell faster than acceleration due to gravity.

The times you are using from the NIST site are not the total collapse times. This has been pointed out to you before by AZCat, but I will repost the excerpt he used from that NIST page in his previous reply to you.

NIST estimated the elapsed times for the first exterior panels to strike the ground after the collapse initiated in each of the towers to be approximately 11 seconds for WTC 1 and approximately 9 seconds for WTC 2.

Clearly they are not implying that these times are the times for either total collapse - as would be indicated by the following additional excerpt:

Neither the duration of the seismic records nor video evidence (due to obstruction of view caused by debris clouds) are reliable indicators of the total time it took for each building to collapse completely.

For you to continue to assert that these times are indicative of the actual collapse times does nothing to strengthen your argument. In fact, it almost makes it look like you need to misrepresent the facts of your case in order for it to have any validity.

If you believe having a classroom full of students time the collapses would be an appropriate method to get a good average, then why are you using the NIST times for the "first exterior panels to strike the ground after the collapse initiated in each of the towers" as the total collapse times? Why don't you have some students, or anyone else for that matter, actually time the collapses to get an average. Hell, even if you were to estimate the times yourself from watching videos it would be better than misrepresenting what the times presented by NIST actually mean.
