To many, I think that will seem an irrational determination to believe something regardless of the evidence.

FEMA AND NIST DON'T AGREE ON WTC7

That's just a start. Lemme know if you want me to prove you wrong some more.

You need to learn some basic physics my friend.
Assuming that the speed of gravity in new york is the same as everywhere else on the planet, where on earth do you get 3.9 seconds from?
WTC collapsed in freefall mode in a little over 7 seconds, its on video
You repeatedly quote NIST yet they have been proven to have fabricated evidence to fit their theories.
Stop trying to belittle Richard Gage, he is an accomplished architecht, You are not, how do I know that? I just know.
PEACE,

I wonder if anyone who criticizes the NIST and everything, ever bothers to read the reports first. Like actually going to the site and downloading the report and reading it line by line, and not going to infowars or rense, or any conspiracy site.
I was referring to how NIST analyzed the video that was suggesting "free-fall" and their conclusions. I apologize if I wasnt clear enough earlier.
www.nist.gov...
In a video, it appears that WTC 7 is descending in free fall, something that would not occur in the structural collapse that you describe. How can you ignore basic laws of physics?
In the draft WTC 7 report (released Aug. 21, 2008; available at wtc.nist.gov...), NIST stated that the north face of the building descended 18 stories (the portion of the collapse visible in the video) in 5.4 seconds, based on video analysis of the building collapse. This time period is 40 percent longer than the 3.9 seconds this process would have taken if the north face of the building had descended solely under free fall conditions. During the public comment period on the draft report, NIST was asked to confirm this time difference and define the reasons for it in greater detail.
To further clarify the descent of the north face, NIST recorded the downward displacement of a point near the center of the roofline from first movement until the north face was no longer visible in the video. Numerical analyses were conducted to calculate the velocity and acceleration of the roofline point from the time-dependent displacement data. The instant at which vertical motion of the roofline first occurred was determined by tracking the numerical value of the brightness of a pixel (a single element in the video image) at the roofline. This pixel became brighter as the roofline began to descend because the color of the pixel started to change from that of the building façade to the lighter color of the sky.
The approach taken by NIST is summarized in Section 3.6 of the final summary report, NCSTAR 1A (released Nov. 20, 2008; available at wtc.nist.gov...) and detailed in Section 12.5.3 of NIST NCSTAR 1-9 (available at wtc.nist.gov...).
The analyses of the video (both the estimation of the instant the roofline began to descend and the calculated velocity and acceleration of a point on the roofline) revealed three distinct stages characterizing the 5.4 seconds of collapse:
Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall).
Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall)
Stage 3 (4.0 to 5.4 seconds): decreased acceleration, again less than that of gravity
This analysis showed that the 40 percent longer descent time—compared to the 3.9 second free fall time—was due primarily to Stage 1, which corresponded to the buckling of the exterior columns in the lower stories of the north face. During Stage 2, the north face descended essentially in free fall, indicating negligible support from the structure below. This is consistent with the structural analysis model which showed the exterior columns buckling and losing their capacity to support the loads from the structure above. In Stage 3, the acceleration decreased as the upper portion of the north face encountered increased resistance from the collapsed structure and the debris pile below.

So, you slag off NIST as a "shady government agency" and when I ask you for professional bodies disputing NIST's findings you suggest a government agency ! Something is not gelling here.
Can you direct me please to any professional body or association in the western world, with relevant qualifications e.g. structural engineering, architecture etc, which is disputing NIST's findings about WTC 7 ?

I assume we are talking about WTC 7 so it would be helpful if you could let me know which scientists exactly we are talking about. Thanks.
The former head of the Fire Science Division of the government agency which claims that the World Trade Centers collapsed due to fire (the National Institute of Standards and Technology), who is one of the world’s leading fire science researchers and safety engineers, a Ph.D. in mechanical engineering (Dr. James Quintiere), called for an independent review of the World Trade Center Twin Tower collapse investigation. “I wish that there would be a peer review of this,” he said, referring to the NIST investigation. “I think all the records that NIST has assembled should be archived. I would really like to see someone else take a look at what they’ve done; both structurally and from a fire point of view. … I think the official conclusion that NIST arrived at is questionable.
Dr. Quintiere also expressed his frustration at NIST's failure to provide a report on the third skyscraper that collapsed on 9/11, World Trade Center Building 7. "And that building was not hit by anything," noted Dr. Quintiere. "It's more important to take a look at that. Maybe there was damage by the debris falling down that played a significant role. But other than that you had fires burning a long time without fire department intervention. And firefighters were in that building. I have yet to see any kind of story about what they saw. What was burning? Were photographs taken? Nothing!"
World Trade Center Building 7 was 610 feet tall, 47 stories, and would have been the tallest building in 33 states. Although it was not hit by an airplane on 9/11, it completely collapsed into a pile of rubble in less than 8 seconds at 5:20 p.m. on 9/11. In the 6 years since 9/11, NIST has failed to provide any explanation for the collapse. In addition to NIST's failure to provide an explanation, absolutely no mention of Building 7's collapse appears in the 9/11 Commission's "full and complete account of the circumstances surrounding the September 11, 2001 terrorist attacks."

i'm sorry I thought that was what you were looking for!
i believe FEMA is qualified...
so since I proved you wrong you think something isn't "gelling"?
wtf...
anyway here ya go:

I can keep going... can you?
If they aren't qualified than I don't know who is!

that doesn't disqualify my opinion.
What I do know is I am getting tired
of being called an idiot, moron, and
all the other names that het thrown
around here.
I wathed a National Geographic show
about the conspiracy theories because
I wanted info. Knowledge brings wisdom,
except when it came to this issue. The
program showed a steel beam coated
with jet fuel and set ablaze for a specific
amount of time while it was covered in
the fire retardant used in the Towers.
It took forever to heat up to the temp
that steel melts. Then they did the same
without the insulation. In a matter of minutes
the beam became hot enough to warp.
I only bring this up because one of
the conspiracy theories was jet fuel
could not get hot enough to do this.
Even with the proof right in front of
him, the conspiracy theorist claimed
it was unrealistic. That and that alone
persuaded me who was being more
grounded.
Earlier in this thread a poster belittled
another when it came to the way
buildings fall in their own footprint.
The remark was about whether or
not the OS believer knew anything
about buildings being on fire and
if they had ever been in one.
The posters condescending attitude
was uncalled for. To that poster I will
say this to your question. YES. While
I was never in a steel framed building
I have been in numerous wood framed
buildings while on fire.
Now we all wanted to save as much
as we could bit some did collapse.
Some collapsed in on themselves,
some outwards, and some a combination
of the two. We were "pulled" out
too many times to count and for
various reasons. I do not pretend
to have the answers you seek but
I doubt they would make a difference
to you anyways.
Also, heat expands, so yes enough
heated air moving at a fair speed
can and will do some damage, ie.
blow out windows.

Architects and Engineers For 9/11 Truth is a professional association (because it's an association of professionals.)
It is NOT a conspiracy website, it is an association of PROFESSIONALS who are looking for TRUTH.
You must be daft.
no major association will say as a whole that NIST is wrong (except FEMA, which you attacked me over for providing that proof, and are now ignoring it) because they will loose their credibility. That is why INDIVIDUAL professionals must come together to form association like Architects and Engineers For 9/11 Truth.

One of the former NIST scientists was Dr. James Quintiere. I forget the others offhand. But they are familiar with NIST procedure and ability and want a peer review on NIST's work on the WTC.
NIST is such a sham and a disgrace to the American taxpayers.
Everything about their work on the WTC is dishonest and unscientific.
