NIST has joined the people that could not see how a total disintegration of
the Twin Towers could be anything but a controlled demolition.
"NIST Admits Total Collapse Of Twin Towers Unexplainable"
The National Institute for Standards and Technology has been forced to admit
that the total free-fall collapse of the twin towers cannot be explained
after an exhaustive scientific study, implicitly acknowledging that
controlled demolition is the only means by which the buildings could have
come down.
In a recent letter (PDF link) to 9/11 victim's family representatives Bill
Doyle and Bob McIlvaine, NIST states,
"We are unable to provide a full
explanation of the total collapse."
A 10,000 page scientific study only offers theories as to how the "collapse
initiation" proceeded and fails to address how it was possible for part of a
WTC structure to fall through the path of most resistance at freefall speed,
completely violating the accepted laws of physics.
