His arguments are based on scientific principles. They do not have to
be convincing, since scientific laws cannot be changed, such as the
Law of Increasing Entropy. Are you an engineer or physicist?

Yes, I am a structural engineer and registered PE.

How do explain THREE collapses at near free fall speed? First time in
history from fire!

It is called progressive collapse. This is when a smaller less
significant failure causes an overall greater failure.

Where did the energy come from to pulvarize concrete and office
furniture into particles of fine powder?

The concrete and other materials had a large amounts of potential
energy stored when they were raised to a higher elevation in the
building. BTW, you don't need to be an engineer to know this, you
need to have not slept through 6th grade science class.

Where did the force come to *evaporate* steel?

Steel doesn't evaporate. ASCE (an independent non-government
organization) determined from analysis that "The thinning of the steel
occurred by a high temperature corrosion due to a combination of
oxidation and sulfidation.

Why was there moltel metal and yellow-hot metal under the Towers (AND
BUILDING 7) weeks after 9/11? (Those colors are consistant with
thermite explosives.)

Fire. BTW it can be consistant with many things.

Also, why did the government hall away and destroy the evidence before
it could be properly analyzed?

See above about ASCE analyzing the steel.




Mike, you are a registered PE structural engineer?


Sir, in your professional, expert, experienced opinion, what caused this 47
story steel framed building to collapse?
