Email to MIT: Molten Metal at the WTC

I sent this simple question to Thomas W. Eagar, the Thomas Lord Professor of Materials Engineering and Engineering Systems, about his paper: Why Did the World Trade Center Collapse? Science, Engineering, and Speculation.
http://www.tms.org/pubs/journals/JOM/0112/Eagar/Eagar-0112.html#ref5
I asked him to speculate about the existence of molten metal at the WTC. So far I have not received a reply. I would recommend that concerned citizens contact the authors of this paper that is so obviously inadequate to ignore some of the most pertinent phenomenon surrounding the WTC collapses.

For more information, contact T.W. Eagar, MIT, 77 Massachusetts Avenue, Room 4-136, Cambridge, Massachusetts 02139-4301; (617) 253-3229; fax (617) 252-1773; e-mail tweagar@mit.edu.


Sir,
With regard to your paper on the WTC tower collapses (link below) you leave out an important part of the phenomenon, that being metal that was melted. There was nothing in the WTC or the planes that can account for this molten metal. There are newly discovered sulfated metal spheres in dust samples from the WTC towers, discovered with an electron scanning microscope, the elemental composition of these metal spheres is also now know by means of spectroscopy. How do you account for the molten metal?
Best regards,
