The first two sentences are incomplete and do not make any sense.
"I guess a lot of you have heard about the website ae911truth where a group of individuals claim that what happened to WTC 1, 2 and 7 could not have happened."
The author did not finish the sentence. It should read: "... what happened to WTC 1, 2 and 7 could not have happened without explosives."
"This is just a claim, because they have nothing to show for their allegation that it could not have happened the way it did." Again the author fails to include "without explosives".
Then he says: "You won't find any calculations that show how the NIST Report is wrong."
David Chandler pointed out that NIST was incorrect in asserting that WTC 7 did not fall at FFA. His calculations, later duplicated by NIST, showed that WTC 7 fell at FFA for ~2.25 seconds.
Tony Szamboti calculated the sag of the floor beams. He produced a spreadsheet and a graph that showed that the loss in length due to sagging would exceed the length increase due to thermal expansion about 650
oC and the maximum net expansion would be about 4.75 inches. [no one has produced a data set that says otherwise]
The author fraudulently claims that 123,000 members of the ASCE, the 80,000 members of the AIA, the 120,000 members of the ASME, the 370.000 members of the IEEE, the 40.000 members of the AIChE and the 35,000 members of the AIAA, do not question the NIST report.
In fact, the author has no idea what all those people think.
