Michael Shermer is 95% Hot Air on the WTC Collapses

Has anyone noticed that there is a new "911 Truth Denier" phrase floating around?
It goes somethng like this: "The WTC Towers collapsed vertically because they were 95% air".
I realize it is hard to believe anyone would use this "reasoning", even government shills.
However, here is one example of it's use, from a recent article by Michael Shermer in Scientific American: "Conspiricists argue that the buildings should have fallen over on their sides, but with 95 percent of each building consisting of air, they could only have collapsed straight down."

I believe the "95%" claim was originally made by Thomas Eager in this paper,.
and then parroted by Shermer and others, such as here.

This statement, of course, is not only meant to explain a vertical collapse, but also to imply that the towers were somehow insubstantial. It is a ridiculous, obvious shill tactic, transparent to anyone with two brain cells to rub together. Whover uses this idiotic phrase needs to be called on it by the 911 truth community immediately.
