at 0:34 does it look like collapsing of a structure, or perhaps falling top
of the building through previously pulverised material at your opinion?
...controlled demolition....

@richard20bris Stop speculating! We need a real investigation first. Dozens
of major cities in Europe are engaging in a decentralized 9/11 action day
with people demanding a real investigation. On 9/11, 30.000 people died
because of hunger! When are we launching the WAR AGAINST HUNGER?!? Tanks to
tractors!

I think we seriously need to make better building codes when it comes to
building tall like the WTC buildings. More people could have gotten out and
been saved had the buildings have been shorter. We all know the truth of
the matter is that people died because those buildings were way too high
for even the highest fire engine ladder to reach. We need stricter building
codes and to stop building that high in case something like this happens
again. We would be stupid to think it wont happen again.
well nobody 'on the outside' knows ANYTHING for sure. Except that EACH of
the floors were artificially and catastrophically weakened (i.e. - lost
100% of their bearing capacity). So the question is then 'how does that
happen?'. Explosives would be the easiest way to do that. There are OTHER
possibilities though - however FAR less likely. Come on - you have a high
school education I presume. USE IT.
"And even though the 47 story building collapsed in under 10 seconds..." 7
seconds...just thought I'd point that out for them.

This video has no ratings. That's because we need another rating button::
"Complete Bullshit" button. This is an example of what happens to a nation
and it's people when there are godless moralless monsters running amuk. Not
in airplanes. In politics.

History Channel, can I please have 3 minutes of my life back? What a load
of garbage! Halfway through we are told "truss failure" and at the end we
are told - as we could not undergo any analysis of the debris we can not
come to a conclusion. I conclude that this is the worst documentary I have
ever watched. Complete garbage!

So the building was so poorly engineered that the weakening of one truss
could bring the entire thing down, because of how it was interconnected? I
guess state of the art in 1987 was to build huge house of cards structures.
I don't buy it the thing was probably way over-engineered to take many
times the loads that it had n it that day.

@KnastPlanet I suppose President Obama must be part of the September 11
"inside job", given that he has done absolutely nothing to look into your
(ridiculous) claims...which would make it one of the most horrific crimes
of the 20th century.
This building traditionaly build like the empire state and it also
collapsed this strange day!

@KnastPlanet Yea, and the FBI killed JFK and the gov. has a profile on
every US citizen! (Ok maybe the last one, but not the first)

Yes, free-fall rate at both penthouses collapses and free-fall rate for the
first 2.5 seconds of the perimeter.
I'm an architect and have a professional engineering license - and it
doesn't matter HOW bad the construction/design - this simply DOES NOT
happen to buildings. This is not a natural collapse in my opinion.

WTC7 was professionally demolished, it fell with partly freefall
accelleration symmetrically into its own footprint. They cann't rig a
burning building in 7 hours, that means someone had foreknowledge! 9/11 was
the only day in history that burning steestructures were able to
symmetrically collapse into their own footprints, producing pools of molten
metal (cf. firefighters) and ironrich microspheres (cf. particle atlas of
World Trade Center Dust). 9/11 was an inside job!

Well, it was partially built over a substation. Therefore, there was very
likely certain degree of redundancy. But according to NIST theory there was
none, just a house of cards.
