- Gravity pulls straight down, not sideways. When a building has widespread compromises in the vertical structural integrity of its systems, it falls DOWN. Tilting during falling really only happens in the movies. Buildings don’t have the lateral structural strength to be accelerated sideways, regardless of local forces involved. They fall down.
The problem is, huge steel beams were ejected as far as 600 feet away from WTC1 and 2, and it has been calculated that the initial velocity of these beams was more than 70 mph, in a lateral direction. So, what was the force that ejected these beams and girdles? - It was an explosion. With simple gravitational collapse, nothing should have been ejected like that.
Also, windows were broken as far away as 400 feet from the buildings, apparently by some sort of shock wave during the collapse. Once again, that has never happened in other building fires. The fact that windows were broken by a shock wave propagating through the air, 400 feet away, indicates that explosion/explosions were taking place while the buildings were collapsing.

Re: Request for meeting regarding NIST Reports - WTC7 and Twin Towers
Dear Dr. Sunder,
We have heard you state publicly after the WTC 7 press conference that it “would not be
productive” for you to meet with the Architects & Engineers for 9/11 Truth. This is quite
disappointing – as we now have over 700 architects and engineers at AE911Truth calling for a
real investigation into the destruction of the three World Trade Center high-rises on 9/11. At
what point will you take us seriously? Perhaps when our rapidly growing numbers reach 1,000
A/E’s?
Here are our talking points:
Why did more than 100 FDNY first responders describe, in great detail, the sounds of
explosions and flashes of light that they saw and heard just before and during each
tower’s collapse? Why did we not know about these thousands of pages of FDNY “oral
history” evidence until August, 2005 – and only then after a court order for their release?
FDNY’s own Chief of Safety, Albert Turi, and FDNY’s chief, Ray Downey, the
“premiere collapse expert in the country” according to a fellow chief, both spoke of the
presence of explosives in the Towers prior to their failures. More than 100 testimonies13
referring to multiple, violent explosions were ignored and unreported by the 9/11
Commission, NIST and FEMA.
What was the energy source, and through what mechanism was it applied, that pulverized
400,000 cubic yards of concrete into a fine powder14 in mid-air that blanketed
Manhattan? Calculations15 show that the energy requirement for this pulverization and
the rapid expansion of the subsequent dust clouds was far greater than the available
gravitational potential energy of the structures. This simple energy imbalance alone
proves the official explanation impossible. Is this the same energy source that is
responsible for the vaporization of more than 10,000 steel file cabinets and 1,100 human
bodies that were never found, not even the smallest traces of DNA?
How were 4 ton steel members ejected16 from the Twin Towers at 70 miles per hour –
and landing 600 feet away? A simple gravitational collapse would only allow up to 100
feet of “drift,” so what provided the energy required?
Why were virtually no floors found17 at the base of either Twin Tower? There were
originally 110 floors in each Tower – each of them one acre in size. What explains the
disappearance of 220 acres of four-inch thick concrete (180,000 tons) and the steel
decking and trusses?
What caused the explosive ejections of pulverized building materials18 as many as 60
stories below the rapidly descending “collapse” of each Tower? These so-called “squibs”
can be seen in many publicly available videos and show materials being ejected at over
160 feet per second.
Why were most windows within 400 feet of each Twin Tower blown out19? This has
never been observed following other gravitational collapses. What was the energy source
here?
Why has an international team of scientists found nanothermitic explosives residue20 (not
ordinary thermite) in the World Trade Center dust? NIST has refused to test for
explosives residue, saying that such tests “would not necessarily have been conclusive.”21
This was clearly nonsense, even before others found the residue, especially since NIST
did not test for ANY kind of explosives residue. NFPA 921 requires such testing when
there is “high order damage,” as there obviously was at the World Trade Center, and it
mentions ordinary thermite by name. Even if NFPA 921 is considered a guideline and not
a law, the failure to follow it in this case is inexcusable, and might very well have helped
allow as-yet unknown perpetrators to escape justice. See also his “Wake Up and Smell
the Aluminothermic Nanocomposite Explosives,” 3/3/09.
