i still want to know why those two buildings came down........the
planes did not do it...........what did????? and why????

Did you miss the fires that were burning in the building ? The planes
weakened the structures AND stripped the fire retardent from the support
members. After that, the fire softened the supports and sheared the bolts
holding them. With nothing to tie the inner structure to the outer shell
structure, down they fell.
P.S. I gotta ask.............What is with the period abuse you always use

yes that is what we were all told.......but do you believe it.????

you,.......if it was so cotton picking hot in there how can anyone
walk around in it........????? nope....this crap does not

strapped to the main columns in the basement to bring them
down......if you will also remember, some guys tried that before in

they parked in the basement was parked next to the wrong support

The people you saw "walking around" were the ones stranded above the impact,
and had gotten as far down as the stairs would let them. The only reason you
saw them at all, was they were slowly roasting and suffocating from the
massive fires and hanging out the windows. Did you not see them jumping from
a height of 70 stories or so ?
As far as bombs in the sub-levels bringing it down, hogwash.. Did you also
miss the TOPS of both buildings collapse onto the damage, and pile the rest
into dust ?
The building was designed to take a hit from aircraft such as a 707, but
the thousands of gallons of diesel that burned were never really thought
about, especially from larger, modern jets. If the building had just been
lit on fire on its own, it most likely would never collapse. But when tons
of debris strips fire retardant from the crossmembers, the steel got hot and
sagged.
I'm sorry you dont believe it, but its the truth. Seems like everyone out
here wants your side of the real conspiracy. So do I..

ok bud you are factually wrong on some points. a staircase was still
viable on the south tower to let people escape.
where did you get the idea that planes use diesel? jp5 maybe but
certainly not glow plugs in a fanjet...
lastly, there were very few 'cross members' as you stated because the
supporting steel was actually the exoskeleton of the building. in other
words the outside of the building supported the entire structure. unique
yes but that was the wtc....

That is flat out false. The building was supported by a rigid central
core. The exoskeleton was designed to absorb wind loads and not apply
those loads to the central core. The gravitational loading of the
building was supported by the central core.

Obviously, those who could make it to a staircase did. Those planes tore up
6 floors when they banked going in. Not everyone was lucky enough to be able
to make it to access down. I wasnt trying to be absolutely perfect in my
reply, just explaining. Jet A and diesel burn pretty much the same, i was
using it for example only (i will be anal retentive and explain things
excessively next time), sorry for that too. As for the crossmembers, look
again. The "crossmembers" that tied the inner core with the outer
exoskeleton, were the floor joists that ran all around the core and were
tied with just a couple or few bolts on each end. And even those were only
1/2" or 5/8" bolts. When the floor joists sagged, the bolts were ripped
apart by tension. Those bolts were never intended for tension, just shear.
Thats when the outer exoskeleton buckled, and the collapse began.
Unique is right too Jim. They dont build em' like that anymore. And i bet
they never will again either ;)

Why don't YOU tell us then genius?

Then you can shut your retarded ****ing face and get a life.

What a freakin' asshat.


Yeah, he tends to be a bit thick at times, but FWIW, he does have some
unique views that may make one think.

Once in the air, almost anyone who has a basic knowledge of the controls and
a couple gauges, can fly. I worked for a charter company as a ramp rat for a
few years, and got to grab the yoke of a King Air 100 and 200 during
post-maintenance check flights. Even in a smaller twin turboprop, keeping a
level flight isnt that hard. And by the way the planes hit the buildings
with course corrections right before impact, just shows theres a little
terrorist in all of us. And those who did the flying, had recently learned
the basics too.
The estimate was 1/3 of the fuel flashed on the outside, and the other 2/3
started the office materials burning. The impact plowed a lot of materials
out the other side, just not hardly enough to keep the fires down. Estimates
on the temps were around 1500 to 2000 degrees i believe.
As far as the "why", everyone has their own opinion on that, and i wont
waste anyones time on it.

The buildings were not designed to withstand the impact of a jet liner full
of fuel. The fuel burned and set fire to paper, carpet, funiture, and tons
of other flamable items. If only the jet fuel had been burning, it would
have burned fast and likely the fire would have subsidee before it became
hot enough to weaken the supporting structure to the point of failure. It
was not just the jet fuel.

Do you have to work at being a moron or does it come naturally "doncha
know"?

They had flight training and had time in simulators. They knew to turn off
the transponders, they new how to read headings. After a few hours in a

Other people said that because your statement is flat out false. What
is unique is the fact the outer structure doesn't provide gravitational
support as is found in most other skyscrapers. The weight is born
almost entirely on the central core. Whatever show you two watched was
either in error (doubtfull) or you misunderstood their description.

http://www.skyscraper.org/tallest/t_wtc.htm

Faced with the difficulties of building to unprecedented heights, the
engineers employed an innovative structural model: a rigid "hollow tube"
of closely spaced steel columns with floor trusses extended across to a
central core. The columns, finished with a silver-colored aluminum
alloy, were 18 3/4" wide and set only 22" apart, making the towers
appear from afar to have no windows at all.

Gee, wonder why when the buildings collasped they fell inward toward the
center followed by the outer walls? Did you notice when the second building
collasped the tv antenna on top fell straight down in the center and that is
were it wound up at the bottem? If this center column was the strength of
the building, then just how did that happen? Did you notice that after the
collaspe that the only things standing were some of the outer walls, no part
of any center column? Whe? Because the center columns were NOT the main
strength of the building, that was in the outer steel structure. That was
pointed out in the documentery by both the Architect and Engineer who
designed the buildings. So this website is either in error or you

The inner core supported the weight of the building, the exterior
columns were designed for wind loading.
The outer wall remained after the collapse because they weren't the
primary support for the building.


The report on the design of the building by the architects reads as
follows:

In order to make each tower capable of withstanding this wind load,
the architects selected a lightweight perimeter tube design consisting
of 244 exterior columns of 36 cm square steel box section on 100 cm
centers (see Figure 3). This permitted windows more than one-half
meter wide. Inside this outer tube there was a 27 m × 40 m core, which
was designed to support the weight of the tower. It also housed the
elevators, the stairwells, and the mechanical risers and utilities.
Web joists 80 cm tall connected the core to the perimeter at each
story. Concrete slabs were poured over these joists to form the
floors. In essence, the building is an egg-crate construction that is
about 95 percent air, explaining why the rubble after the collapse was
only a few stories high.

Maybe you misunderstood what the documentary stated. I also watched
it, and the mention of the outer columns was in reference to wind
loading, not support of the weight of the building.

The floors of the buildings were built from trusses, with one end attached to
the central core and the other end attached to the outer columns. That means the
weight of each structure was supported by BOTH the outer shell AND the inner
core.

Now how about arguing over something a little less morbid, huh?

Other people said that because your statement is flat out false. What
is unique is the fact the outer structure doesn't provide gravitational
support as is found in most other skyscrapers. The weight is born
almost entirely on the central core. Whatever show you two watched was
either in error (doubtfull) or you misunderstood their description.

Faced with the difficulties of building to unprecedented heights, the
engineers employed an innovative structural model: a rigid "hollow tube"
of closely spaced steel columns with floor trusses extended across to a
central core. The columns, finished with a silver-colored aluminum
alloy, were 18 3/4" wide and set only 22" apart, making the towers
appear from afar to have no windows at all.


Gee, wonder why when the buildings collasped they fell inward toward the
center followed by the outer walls? Did you notice when the second building
collasped the tv antenna on top fell straight down in the center and that is
were it wound up at the bottem? If this center column was the strength of
the building, then just how did that happen? Did you notice that after the
collaspe that the only things standing were some of the outer walls, no part
of any center column? Whe? Because the center columns were NOT the main
strength of the building, that was in the outer steel structure. That was
pointed out in the documentery by both the Architect and Engineer who
designed the buildings. So this website is either in error or you
misunderstood their description.


The inner core supported the weight of the building, the exterior
columns were designed for wind loading.
The outer wall remained after the collapse because they weren't the
primary support for the building.


The report on the design of the building by the architects reads as
follows:

In order to make each tower capable of withstanding this wind load,
the architects selected a lightweight perimeter tube design consisting
of 244 exterior columns of 36 cm square steel box section on 100 cm
centers (see Figure 3). This permitted windows more than one-half
meter wide. Inside this outer tube there was a 27 m × 40 m core, which
was designed to support the weight of the tower. It also housed the
elevators, the stairwells, and the mechanical risers and utilities.
Web joists 80 cm tall connected the core to the perimeter at each
story. Concrete slabs were poured over these joists to form the
floors. In essence, the building is an egg-crate construction that is
about 95 percent air, explaining why the rubble after the collapse was
only a few stories high.

Maybe you misunderstood what the documentary stated. I also watched
it, and the mention of the outer columns was in reference to wind
loading, not support of the weight of the building.

The floors of the buildings were built from trusses, with one end attached to
the central core and the other end attached to the outer columns. That means the
weight of each structure was supported by BOTH the outer shell AND the inner
core.

Of course it was supported by the inner and outer shells. But the
inner one was designed to carry the verticle loads.


Now how about arguing over something a little less morbid, huh?


How is it morbid? Discussing a buildings construction isn't morbid.
