Oh, I have seen that video, and I have Googled the name of the firefighter, (who was not there) and it seems that HIS opinion/information can be traced back, thru several steps, to former Prof. Stephen Jones (BYU) who'investigated' the alleged accelerants to further his personal theory:

"Although the article draws no conclusions about the source and purpose of the explosives, Jones has previously supported a theory that the collapse of the WTC towers was part of a government conspiracy to ignore warnings about the 9/11 terrorists so that the attack would propel America to wage war against Afghanistan and Iraq."

Where did these supposed samples of thermite come from? Why, they were " 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."

Where did he get the 1st sample? From the Brooklyn Bridge, he says, soon after the incident. Other 'samples' were scooped up in a couple other places nearer the site, they explain.

"Another man collected dust in his apartment, about five blocks from the World Trade Center, on the morning of Sept. 12. There was a layer about an inch thick on a stack of folded laundry near an open window.

Red/gray chips, averaging in size between .2 and 3 mm, were found in all four dust samples."

Wow! There's some detailed, documented scientific inquiry for you! Who did the fancy 'analysis' of the 4 tiny chips (.2 mm)? A lab in Denmark. When did they do it? Evidently in 2006, after Stephen Jones, who was needing to support his already controversial theory 'requested' some samples of dust, and 'received' it from those carefully documented sources noted above. (I cannot find where Jones' 'request' was made, and why he trusted the source).

The analysis 'revealed' that the samples were mostly iron oxide, with 'some' fine aluminum....both of which 'can be' associated with thermite.

THIS is the complex chain of 'evidence' which has prompted Eric Lawyer and several others to assure us that we are being deceived and prevented from 'finding the truth'.

These sites also either originate or repeat that line about "only a few small fires" in WTC 7.....when firefighters who were there assure us that the fires were much larger and did so much damage that they were not even able to enter the building...and were damn glad of it!

Do you wonder why close-minded ol' Bill D. sighs in frustration when I am accused of just relying 'on my own beliefs' when THAT is how the evidence you want me to consider is presented?

I have read YOUR evidence....have you followed and read the links *I* have provided for several years? Go that very long thread noted above (like...700+ posts..) and re-read it.
