The terrorists you and other anti-semites support hijacked commercial
aircraft fully-laden with fuel for transcontinental flights, flew them
into buildings (and a field), two of which were the two main WTC
buildings. The initial impact and resulting fire weakened the steel
structure, causing floors above and below the impact areas to collapse.
This caused undue stress on the remaining structure, which gave way
floor by floor as it pancaked down. It went down instead of up because
of gravity, a natural force you irrationally reject out of hand.

I've given you links to reports written by engineers which detail the
metal fatigue caused by the impact and fire. Their reports on the steel
are based on scientific metalurgical testing. Their analyses of the
collapse is based on their expertise in the field.

You've given us a load of BS from crackpot conspiracy theory sites. Your
"experts" consist of an elderly economist who was put out to pasture
some time ago by the administration, a "cold fusion" proponent whose
fellow faculty members have disowned him and his loony beliefs about
9/11 (tenure is not a good thing), and a cast of assorted nutjobs who
have no experience in metals science, engineering, or any relevant field
-- just like you.
