Abstract: We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the
destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in
this paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan
resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later.
The properties of these chips were analyzed using optical microscopy, scanning electron microscopy (SEM), X-ray energy
dispersive spectroscopy (XEDS), and differential scanning calorimetry (DSC). The red material contains grains approximately
100 nm across which are largely iron oxide, while aluminum is contained in tiny plate-like structures. Separation
of components using methyl ethyl ketone demonstrated that elemental aluminum is present. The iron oxide and aluminum
are intimately mixed in the red material. When ignited in a DSC device the chips exhibit large but narrow exotherms occurring
at approximately 430 ?C, far below the normal ignition temperature for conventional thermite. Numerous iron-rich
spheres are clearly observed in the residue following the ignition of these peculiar red/gray chips. The red portion of these
chips is found to be an unreacted thermitic material and highly energetic.
INTRODUCTION
The destruction of three skyscrapers (WTC 1, 2 and 7) on
September 11, 2001 was an immensely tragic catastrophe
that not only impacted thousands of people and families directly,
due to injury and loss of life, but also provided the
motivation for numerous expensive and radical changes in
domestic and foreign policy. For these and other reasons,
knowing what really happened that fateful day is of grave
importance.
A great deal of effort has been put forth by various government-
sponsored and -funded investigations, which led, in
large part, to the reports released by FEMA [1] and NIST
[2]. Other studies of the destruction have been less well
publicized but are no less important to the outstanding obligation
that remains to the victims of that tragedy, to determine
the whole truth of the events of that day [3-10]. A number of
these studies have appropriately focused attention on the remaining
physical material, and on available photographs and
video footage, as sources of evidence still in public hands,
relating to the method of destruction of the three skyscrapers.
The collapses of the three tallest WTC buildings were
remarkable for their completeness, their near free-fall speed
[11] their striking radial symmetry [1, 12] and the surprisingly
large volume of fine toxic dust [13] that was generated.
In order to better understand these features of the destruction,
the authors initiated an examination of this dust. In June
2007, Dr. Steven Jones observed distinctive bi-layered chips,
with both a red and a gray layer, in a sample of the WTC
dust. Initially, it was suspected these might be dried paint
chips, but after closer inspection and testing, it was shown
that this was not the case.
