president, traveled to the John F. Kennedy International Airport,
where the last remains of the towers are being stored in an 80,000-
square-foot hangar. Huston and DiOrio met with New York Port
Authority officials about bringing some of the remnants back here.
It turns out last remains of the Towers are being stored in an
80,000-square-
This is crucial evidence that could answer many questions about high-
rise building design practices and performance under fire
conditions.

The existence of molten metal at Ground Zero
For six months after Sept. 11, the ground temperature
varied between 600 degrees Fahrenheit and 1,500 degrees, sometimes
higher. "In the first few weeks, sometimes when a worker would
pull a steel beam from the wreckage, the end of the beam would be
dripping molten steel," Fuchek said. (Walsh, 2002)
Sarah Atlas was part of New Jersey's Task Force One Urban Search
and Rescue and was one of the first on the scene at Ground Zero with
her canine partner Anna. She reported in Penn Arts and Sciences,
summer 2002,
`Nobody's going to be alive.' Fires burned and molten steel flowed
in the pile of ruins still settling beneath her feet. (Penn, 2002;
emphasis added.)
Notice that the molten metal (probably not steel alone; see
discussion below) was flowing down in the rubble pile early on; so
it is not the case that the molten metal pools formed due to
subterranean fires after the collapses.
There are several published observations of molten metal in the
basements of all three buildings, WTC 1, 2 ("Twin Towers") and 7.
For example, Dr. Keith Eaton toured Ground Zero and stated in The
Structural Engineer,
Nor does NIST (or FEMA or the 9-11 Commission) even mention the
molten metals found in the basements of all three buildings (WTC 1,
2 and 7).
It is difficult to reach temperatures above 650°C in the type of
diffuse fires evident in the WTC buildings, let alone in the steel
columns where heat is transported away by the enormous heat sink of
the steel structure.
How were these ~1000°C temperatures in the steel beam achieved? It
takes 1500 °C to melt steel.
///// Analysis of a few pieces of the twin tower steel
One of the relatively few previous peer-reviewed papers relating to
the WTC collapses provides was analyzed, a _Microstructural
Analysis of A36 Steel from WTC Building 7_. This analysis shows the
Rapid deterioration of the steel was a result of heating with
oxidation in combination with intergranular melting due to the
presence of sulfur. The formation of the eutectic mixture of iron
oxide and iron sulfide lowers the temperature at which liquid can
form in this steel.
How did this mysterious sulfidation of the steel reported in this
paper occur -- What is the origin of this sulfur? Thermate is a
high-level thermite analog and it contains sulfur.
The evidence for the use of some variant of thermite such as sulfur-
containing thermate in the destruction of the WTC Towers and
building 7 is sufficiently compelling to warrant serious
investigation.
The WTC Towers were designed to withstand forces caused by large
commercial aircraft – we can agree on that. MIT's Thomas Eagar also
concurs "because the number of columns lost on the initial impact
was not large and the loads were shifted to remaining columns in
this highly redundant structure" (Eagar and Musso, 2001).
The conflagration, caused by the aircraft fuel spilled into the
structure, causes the steel of the columns to be exposed to
sustained temperatures apparently exceeding 800oC… (Bazant and
Zhou, 2002, p. 2.)
The NIST report states that: "The initial jet fuel fires themselves
lasted at most a few minutes" and office material fires would burn
out within about 20 minutes in a given location. (NIST, 2005; p.
179, emphasis added.) Certainly jet fuel burning was not enough to
raise steel to sustained temperatures above 800oC. Using
metallographic analysis, NIST determined that there was no evidence
that any of the samples (of steel) had reached temperatures above
600 ºC. (NIST, 2005, pp. 176-177; emphasis added.)
Kevin Ryan, the whistleblower from Underwriters Laboratories, did
his own brief statistical analysis estimates that the probability
that fires and damage (the "official theory") could cause the Towers
complete collapse is less than one in a trillion, and the
probability is much less still when the complete collapse of WTC7 is
included.

28 December, 2002: Steel salvaged from the wreckage of the World
Trade Center in New York has been sent to a Mississippi shipyard to
be used in the construction of a new US warship.
Almost immediately after 11 September, New York authorities started
looking for ways to deal with the 1.6 million tons of wreckage.
After investigators combed through it, extracting human remains and
personal effects, more than 350,000 tons was sold for recycling in
China, Malaysia, Korea and India.
The World Trade Center steel was thought to be some of the heaviest,
thickest steel ever used in construction. Its outer skeleton
comprised of steel beams up to two feet thick.
