One contractor hired to dispose of evidence
at the World Trade Center sites
was Controlled Demolition, Inc.,
a Maryland-based company that was also responsible
for the immediate confiscation and destruction of remains
of the Murrah Federal Building in Oklahoma City after that building exploded,
killing 168 people, on April 19, 1995.
Police found several unexploded bombs in the Murrah Building,
a fact reported by several local TV news stations
but not by national TV Networks.
Retired Brigadier General Benton K. Partin, an expert in demolitions
over his 31-year career in the U.S. Air Force,
presented detailed proofs to the U.S. Congress in 1997
that the Murrah Building must have been demolished
by internal explosives and not by an external truck-bomb.
In June 1997 the U.S. Air Force Base in Eglin, Florida
issued a 56-page
on the Murrah bombing that stated:
It must be concluded that the damage at the
Murrah Federal Building is not the result of the truck bomb itself
but rather due to other factors such as locally placed charges
in the building itself.
The damage to the Murrah Building included a deep notch
caused by the pulverization of a steel-reinforced concrete pillar.
The blast pressure from the truck bomb on that pillar was only
27 pounds per square inch.
Congress and official investigators ignored
both General Partin's and the Eglin Air Force Base Study's findings.
