Editor’s Note: This is Part 8 (see Part 7) of an extensive report by 9/11 researcher Adam Taylor that exposes the fallacies and flaws in the arguments made by the editors of Popular Mechanics (PM) in the latest edition of their book Debunking 9/11 Myths. We encourage you to submit your own reviews of the book at Amazon.com and other places where it is sold. We also refer you to the landmark documentaries from AE911Truth on WTC 7: 9/11: Blueprint for Truth and 9/11: Explosive Evidence – Experts Speak Out.(Quotes from Popular Mechanics’ book are shown in red and with page numbers.)

Part 8:
WTC 7 Wreckage Pile

PM’s next section discusses the actual collapse of WTC 7 and the condition of the wreckage pile after it collapsed. It creates the impression that both of these issues can be explained by natural means rather than demolition. As we shall see, this is simply not the case, as with virtually all of PM’s arguments against demolition.

PM rehashes its previous arguments that most of the collapse of WTC 7 occurred inside the building, and was hidden from sight. They also argue that it is reasonable that Building 7 collapsed straight down instead of toppling like a tree. To support this, they cite Protec Demolition Company employee Brent Blanchard, who offers two reasons why Building 7 collapsed straight down:

Blanchard says that ‘conspiracy theorists’ have misappropriated his example of felling a tree for multiple reasons. WTC 7 was 330 feet long at its maximum, and 140 feet wide. Unlike tipping a tree a few feet in diameter, tipping WTC 7 would have required deflecting the building more than 70 feet north or south before its center of gravity moved beyond its base — an incomprehensible margin, particularly because WTC seven sustained no external lateral forces… Secondly Blanchard estimates the interior of WTC seven some 80 to 90 percentage air… Once thousands of tons of steel beams and concrete flooring began to collapse, Blanchard says, the structure had too much inertia to go any other direction. “Trees are inherently rigid monolithic structures,” Blanchard states. “A radio tower could be felled like a tree. You could begin a building’s descent in a certain direction by cutting certain columns, but you cannot fell a building like a tree.” (pg. 74-75)

After more than two seconds of free-fall acceleration, in which the building fell straight down for 100 feet (the key point presented by AE911Truth, which remains completely unaddressed by Blanchard), the upper part of WTC 7 may have had enough inertia to destroy the lower part of the building, but this free fall must be explained by Blanchard – without the use of explosives.

The two arguments that are presented are “red herrings”: a) there were no lateral forces to knock Building 7 over and b) the building was mostly air by volume. Both of these arguments are problematic.

While there were virtually no lateral forces acting on Building 7, this in no way implies that the building could have suffered total symmetrical collapse. The remaining intact structure of the building would have offered incredible resistance after any local failure (NIST cites the failure of column 79 for the initiation of the total collapse) because it is designed to be at least 3x stronger than necessary to support its loads. The law of entropy would ensure an asymmetrical collapse – unless all the supports were removed at the same time, which “normal office fires”, the official cause of this building’s collapse, could not possibly accomplish. Several structures that initially collapsed straight down (due to purposeful professional controlled demolitions – as a result of charges which failed to detonate) have indeed fallen over or have simply stopped collapsing. i
