1. The 9/11 Commission never addressed the collapse of WTC7
2. Photographs of the site were forbidden, the FEMA investigators
were excluded from the site, the materials were removed in great haste
over the protests of the firemen (they rioted because of the
descretation of the dead) and Fire Engineering Magazine
3. The steel was destroyed before adequate samples could be taken.
Since every piece of steel had a stamped id number, it seems the
pieces of interest from the impact floors could have been pulled out
of the pile.
4. The FEMA report was unable to explain why WTC7 came down, and
concluded that their best guess (diesel fires weakened the steel) was
unlikely. FEMA investigators were poorly funded, and had to fight to
see the blueprints, which still have not been made public. The later
NIST report claims that WTC7 fell from structural damage (a ten-story
gash on the south side) for which there is no photographic evidence.
How come FEMA didn't know about this gash?
5. The MIT zipper hypothesis blaming the collapse on weak floor truss
"clips" at the perimeter columns was the conventional wisdom for three
years, though believing that requires that the truss clips at the core
side be so strong that the falling floors took the core down with
them. NIST's recent report claims that the perimeter truss clips were
so gol-darn strong that sagging floors buckled the perimeter columns.
NIST's report contains an excess of irrelevant and distracting detail,
including pictures of hypothesized data that can easily be confused
for measured data. NIST's model stops in time at the initiation of
collapse and stops just below the fire zone--and so it assumes what it
sets out to prove: that the initiation of collapse equals progressive
collapse, a phenominon that appears to have been invented on 9/11.
6. (Sorry. Take away #1) The evidence for the blazing infernos is
very poor. Brian Clarke walked down from the 81st floor of WTC2 right
through the fire zone. He saw a few flames, no inferno. At the 31st
loor he stopped to make phone calls. Walking away down the street
a friend said he thought the tower might fall. Clark said "No way!
That's a steel-frame building!"

Here's a whole page of pictures of the wimpy fires:
http://911research.wtc7.net/wtc/evidence/photos/fires.htmlI would submit that our impressions of a blazing inferno are largely
built on the notion that "jet fuel" necessarily burns hotter than
"kerosene" and on this image here:
Refusal to consider the possibility of explosives is irrational IMHO.
The whitewash investigation is evidence for explosives IMHO.
