The performance of WTC 7 is of significant interest because it appears the collapse was due primarily to fire, rather than any impact damage from the collapsing towers.

stateofgrace,
I disgraced my uniform? Is there no limit to which you will stoop?
Fortunately I know myself very well and the pride with which I have worn both my military uniform and my fire department uniforms for a total of 17 years of my life.

Do you agree a 47 story building "fully involved" in fire would produce at least a spark in the collapse?

Actually, anybody can take the challenge. Everybody really should look at these just to prove it for themselves. Imagine the building fully involved in fire for 47 stories when you do.
In the midst of quite the hissy fit, aren't you?If my word on the history of collapses due to fire is not enough lets review what FEMA says. This is just some of the stuff Gravy leaves out of his cherry picked articles.
You should be excited to know I am working on a WTC 7 piece to show you all of the stuff Gravy left out of the spoon fed info you received. You shouldn't be so dependent on one person!
1) Clearly the building was on fire. You're not denying that, are you?
2) So you don't accept that "fully involved" is a fair description. So what? How does merely being "somewhat involved" for several hours contradict the big picture?:
3) The building was burning uncontrollably; it had suffered some degree of structural damage; the people on the ground noticed signs of impending collapse and were clearly concerned about it; and few who had been following its progress were surprised when it finally did.
I can't possibly answer what FEMA and NIST have not in over 5 years.
I didn't ask you to.
(1) is a yes or no question about your current state of belief.
(2) is asking you how a downgrade in the description of the fire contradicts:
(3) which is a statement of fact.
for Russell.It is not silly to expect to see a 47 story building fully engulfed in fire that is the entire focal point of a city and all of the media and photographers for miles. And a country watching all of the news cameras trained on the most significant event in recent history.
You didn't see it because it is not what happened.
This forum is truly one of the most dishonest places I have evr visited...
NO FLAME.

According to fire service personnel, fires were initially seen to be present on non-contiguous floors on the south side of WTC 7 at approximately floors 6, 7, 8, 10, 11, and 19.
As the day progressed, fires were observed on the east face of the 11th, 12th, and 28th floors (see Figure 5-19). The Securities and Exchange Commission occupied floors 11 through 13. Prior to collapse, fire was seen to have broken out windows on at least the north and east faces of WTC 7 on some of the lower levels.

Ah, the usual CTer simplistic vision of reality. If there's smoke, there's fire, ERGO we should be able to see the fire through metal, smoke, dust.
Hell, people in China should've seen it.
Ah, another person who believes that when someone disagrees with them, they MUST be dishonest because, let's face it, the evidence is SOOooooo convincing.
NO FLAME!
Why have you bolded that text above, are you trying to insinuate that FEMA think the collapse was caused by a controlled demolition?Russell Pickering said:"Loss of strength due to the transfer trusses could explain why the building imploded, with collapse initiating at an interior location."

http://wtc.nist.gov/pubs/WTC Part IIC - WTC 7 Collapse Final.pdfWorking Collapse Hypothesis for WTC 7
If it remains viable upon further analysis, the working collapse hypothesis for WTC 7 suggests that it was a classic progressive collapse, including:
An Initiating Event
An initial local failure at the lower floors (below Floor 13) of the building due to fire and/or debris induced structural damage of a critical column (the initiating event), which supported a large span floor bay with an area of about 2,000 ft2
A Vertical Progression at the East Side of the BuildingVertical progression of the initial local failure up to the east penthouse, as large floor bays were unable to redistribute the loads, bringing down the interior structure below the east penthouse
A Subsequent Horizontal Progression from the East to the West Side
Horizontal progression of the failure across the lower floors (in the region of Floors 5 and 7, that were much thicker than the rest of the floors), triggered by damage due to the vertical failure
Disproportionate Global Collapse
Events resulted in a disproportionate collapse of the entire structure
NIST has seen no evidence that the collapse of WTC 7 was caused by bombs, missiles, or controlled demolition.
Does this hole go all the way down?

If so that is a serious amount of damage to the structure!
Yes you do. For you have abandoned your uniform and now have a new one. You new uniform is a trendy t shirt with “911 inside job” on it, a pair of sun glasses and a baseball cap. This you now wear with pride, this is your new uniform.
Do you wear it to re unions pal? Do you go there and look your former comrades in the eye and tell them all about what you write on the net? Do you tell them how you now wear your new uniform with pride and have made lot of new friends who mock this event? Have you got the nerve to do that pal?
I go to reunions, once a year I meet up with my old comrades, we swap stories, we have a little bit too much to drink and we occasionally get a bit weepy about events that have happened. For I wore a uniform and within this uniform I fought for my country. I fought down in the Falklands many years ago along side my comrades. I, unlike you have not found a new uniform; I have not turned my back on my comrades. I do this with honour, something you have abandoned in favour of ridiculous theories and new found friends over at LC.
The limit of which you speak of is the one you have sunk to. It is you that as lowered yourself to this limit, it is you that has turned his back on his comrades, it is you that has a new uniform.
It is you that has brought shame upon yourself. For you are unable to look your former comrades in their eyes with your new uniform which you wear with pride.
Next time you put your new uniform on, go out and join the rest of loonies that chant disrespectful garbage at GZ and try walking up to the firemen that maybe around and tell them how you once wore a uniform just like theirs but you have abandoned it. Look very closely into to their eyes and try to gauge the reaction pal. It will be one of disgust.
If the current NIST working hypothesis for the collapse of WTC 7 is incorrect in your opinion what do you think caused the collapse?SUMMARY:
1) No photos of significant fires.
2) No video of 47 stories fully involved.
3) No mention of 47 floors of fully involved fire in FEMA. (If that was the case don't you think the FEMA report would have been easy to write?)
4) A scientific explanation for the circulation of the smoke related to the unventilated fuel fires that FEMA did mention.
5) In relation to the fuel fires FEMA said, "Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence."
You guys should just stop. It is looking bad.

Just so you know - I am still very good friends with many of my old firefighter friends. They think I "walk to the beat of a different drummer" as they put it, but many of them agree with me about the collapses. If you even want to know more truth - some of them were there and heard a lot of Ground Zero rumors and at first came back believing secondary devices had been used.
Don't you ever get tired of looking incompetent????
