for all 911 debunkers...molten metal dripping from 80th

Based on the known properties of molten aluminum in the presence of hydrated oxides in
concrete, gypsum and rust we propose the following sequence of events involving
aluminum reactions, brought down the Twin Towers on 9-11:

- Boeing 767 aircraft separately strike WTC 1 & 2 and flaming wreckage becomes
lodged in the upper floors of each Tower.

- Combustibles, such as office furniture, paper and plastic, start to burn, fuelled by at
least 10,00 liters of kerosene, and the temperature in the impact zone begins to rise.

- After about 30 minutes, the fires subside, but black smoke continues to pour out of both
Towers showing that the fires are not “out”, but “smoldering”.

- After about 40 minutes, parts of the airframe in WTC 2 approached the critical
temperature range of 500 - 550 C where aluminum alloys starts to soften and melt.

- At 50 minutes, molten aluminum forms and starts to flow from the airframe in WTC 2.

- The molten aluminum re-ignites some of the smoldering fires and rapidly burns through
other combustible materials that survived the initial conflagration. Molten aluminum also
falls onto concrete, gypsum and rusted steel surfaces inducing violent thermite
explosions, dispersing globules of molten metal and igniting new fires.

- The extreme heat generated by the molten aluminum rapidly weakens already damaged
steel columns and trusses in the impact zone causing local slumping and partial collapse.

- The remains of the semi-molten airframe fall to the floor below and mix with fresh
combustible material, air, water, thermite reagents (concrete, gypsum, rust), and sections
of aluminum cladding from the Tower’s façade, initiating more violent explosions.

- This sequence of events is now repeated in a rapidly accelerating, and increasingly
violent cascade of destruction. Gravity adds momentum to the downward acceleration of
the mass of debris and WTC 2 collapses in less than 16 seconds.

- The burning aluminum remaining at the end of the collapse glows brightly for a
moment and illuminates the rising clouds of smoke and dust at ground zero.

- About 25 minutes later, the temperature of the aircraft wreckage in WTC 1 reaches the
critical 500 - 550 C range where molten aluminum starts to flow. The sequence of
events observed in WTC 2 is repeated in WTC 1 and a second global collapse ensues.

It is indeed ironic that the progressive collapse of the Twin Towers has prompted many
9-11 researchers to reach the erroneous conclusion that deliberately placed thermite
"cutter charges" must have been used to bring down these buildings. The findings
outlined in this article show the underlying reasons for this misconception. Simply put,
thermite-induced reactions were largely responsible for the destruction of the Twin
Towers on that terrible September day in New York City – but the fatal damage was not
from deliberately planted thermite charges.

"Simply put, thermite-induced reactions were largely responsible for the destruction of the Twin Towers on that terrible September day in New York City..."

"“Starting around 9:52 a.m., a molten material began to pour from the
top of window 80-256 on the north face of WTC 2. The material appears
intermittently until the tower collapses at 9:58:59 a.m. The observation
of piles of debris in this area combined with the melting point behaviors of
the primary alloys used in a Boeing 767 suggest that the material is molten
aluminum derived from aircraft debris located on floor 81.”"

Occurrence of Thermite Type Compounds at the WTC
If we look at H & K’s list of compounds that have the potential to induce “catastrophic
explosions” in the presence of molten aluminum, namely, water, lime, gypsum and rust,
we see that all of them were present in the Twin Towers during 9-11:

Water:
The Boeing 767 aircraft impacts caused major structural damage over several floors in
each Tower. Sprinkler systems were installed in the Twin Towers but apparently failed to
operate during the catastrophic events of 9-11. Certainly, however, many plumbing
fixtures near the aircraft impact zones would have ruptured and spilled water, especially
in washrooms and kitchenettes, but also in office areas where water coolers, coffee
makers and drink vending machines would have broken and spilled their contents.

Lime:
Lime is calcium oxide and forms the base for all cements and concretes where it typically
constitutes 60 – 67 wt %. (WTC 1 & 2 contained an estimated 48,000,000 kg of concrete
per Tower.) The principal binding agent in concrete is calcium silicate hydrate. The water
of hydration of this compound, constituting 5 – 7 % of the weight of concrete, is present
in the form of H2O bridges between Ca-O and Si-O layers. This water accounts for much
of the chemical bonding that forms between lime and silica during the manufacture of
concrete. As previously noted, the combination of water and metal oxide bonding in
concrete makes this material very susceptible to explosive reactions in the presence of
molten aluminum.

Gypsum:
Gypsum is hydrated calcium sulfate, CaSO4.2H2O. It is the principal ingredient of
wallboard (75 – 90 wt %) but is also used as a binder or filler in fireproofing and
insulating materials. Large quantities of gypsum wallboard, typically 5/8-inches thick,
were used to enclose exit stairwells and elevator shafts throughout the Twin Towers.

Rust:
Rust, which is essentially a mixture of ferric oxides and hydroxides, readily forms on iron
or low alloy steels exposed to moist air at ambient temperatures. Post 9-11 photographs
of the WTC at ground zero show many rusted steel members in the rubble piles. The iron
oxide film thickness measured on selected samples by NIST and FEMA investigators was
consistent with the expected level of corrosion of carbon steel after 30 years exposure to
the urban/maritime environment of NYC. As shown below, rust may be induced to react
violently with aluminum, both in its molten and solid state.

Since there were no other metals in the Twin Towers that could melt at the temperatures
present in WTC 1 & 2 during 9-11 – i.e. less than 800 C, it must be concluded that
molten aluminum was produced in significant quantities from the melting of airframe
debris in a least one Twin Tower (WTC 2). However, from the different trajectories of
the aircraft strikes on WTC 1 & 2, it appears that the fuselage of the aircraft that struck
WTC 2 came to rest closer to an exterior wall than the aircraft that struck WTC 1 which
stopped deep inside this building. NIST report that the fires in WTC 2 were less active
than those observed in WTC 1. In addition, the maximum temperature reached inside the
Towers was probably higher for WTC 1 than for WTC 2 because Tower 1 burned for 102
minutes compared to 56 minutes for WTC 2. Given these facts, it is probable that molten
aluminum was produced in both Towers, but was only observed at one location, namely
spilling out of a broken window in WTC 2. It is obviously very difficult to estimate how
much molten aluminum was produced in either of the Twin Towers during 9-11.
However, from the temperature and heat flux estimates reported by NIST, and the mass
of aluminum exposed, it is probable that as much as 10,000 kg of molten aluminum
formed in each Tower.
