It has gotta be more fun than humiliating yourself here day after day.
His playing the banjo explains a lot.

I like this because too many debunkers believe complete steel structural collapse due to fire is a common event when in fact its never before happened.
Because it was a relatively slow process. A landslide generates far more energy than a gunshot, but it's the gunshot that hurts your ears. You might want to look up the word brisance. Explosions get attention for a reason, but you know this. You've watched the CD videos.
Meanwhile - for the fifth time - how do you suppose the CD plan would have panned out had WTC7 not been hit by WTC1 debris?

http://www.iconreview.org/news/13656
"and the complete collapse of WTC7 after burning unchecked for approximately seven hours, the team found particularly significant. "Prior to these events, no protected steel-frame structure, the most common form of large commercial construction in the United States, had ever experienced a fire-induced collapse. Thus, these events may highlight new building vulnerabilities, not previously believed to exist."
.
However, the partial collapse of WTC5, not initiated by falling debris, and the complete collapse of WTC7 after burning unchecked for approximately seven hours, the team found particularly significant. "Prior to these events, "
To me it explains that he has the drive to teach himself to play a stringed acoustic instrument. I taught myself to play acoustic guitar and it's not easy.His playing the banjo explains a lot.
so Disbelief, did the upper 33 floors of WTC7 fall as one block or was NIST wrong too?
You should add McCormick Place in Chicago (early 70's?) to your examples. Steel roof on concrete block wall, IIRC. Unsprinklered. Collapsed even though the FD fought the fire.Ok, enough of this. You're probably new enough here to where you haven't seen this brought up over the course of the years, but you need to realize that you're arguing from a false premise and stating an invalid conclusion. First of all, the fact that it's never happened before doesn't mean it is impossible to happen. Second, the one actual controlled experiment - the Cardington tests - did indeed demonstrate what happens to steel when exposed to intense fires. The distortions evident from the Cardington test inform our understanding of the WTC collapses, and demonstrate clearly that the sorts of failure modes either observed in the steel (the main towers) or modeled (WTC 7) can and indeed will occur. Creep, severe distortion of a structure, expansion, etc. were observed in the test rig, and when you apply the principles of behavior established in those tests to the specifics of how either the Twin Towers or 7 World Trade were constructed, you can clearly demonstrate that the fires effects could and indeed did collapse the towers.
There were multiple factors in each towers collapse. For the main towers, the design led to the unfortunate fact that debris impacting the floors sever lateral supports, leading to unstable exterior columns. For 7 World Trade, there's the design that left it vulnerable to thermal expansion of the long-span trusses. Until and unless those are taken into account in analyses, as well as the other unique issues at work that day - not the least of which was the severe damage from the impacts to the main towers, nor the extreme length of time the fire affected 7 World Trade - then blithe write-offs of the notion of steel structures not collapsing under fire are nothing more than demonstrations of ignorance. All the details apply, not simply the gross comparison of steel framed structures.
Furthermore, remember that while there are zero cases of high-rise buildings that are entirely steel framed collapsing, there are indeed cases of steel structures doing so. Take the Kader Toy factory as an example: The only part of the building that remained standing was the non-steel part. The steel part of the structure suffered total failure.
There are other examples I cannot recall off the top of my head. But this argument has been tried before, and has failed. See past threads, such as this one: http://www.internationalskeptics.com/forums/showthread.php?t=133271
The point is that you're attempting to claim that steel structures do not collapse when subjected to fire. All the research that has been done by engineers such as the Arup and University of Edinburgh ones, by the various fire and structural engineering researchers in the US, such as Astaneh-Asl and James Quintiere, and so on all point to the fact that steel can indeed collapse in fires. The fact that no skyscraper has done so yet is a canard: Few suffered the same sorts of fires, none suffered jet impact damage, and among the biggest fires in history, only two or three (Beijing CCTV and Andrus Bank fire in Brazil) were even remotely as large, and I can't think of any off the top of my head where not only no fire retardation systems (i.e. sprinklers, firewalls, etc.) rendered ineffective, but no active firefighting was conducted. The point is, saying that no steel structures have ever collapsed due to fire is like saying no human has ever been killed by supernova or stellar phenomena: The principle is demonstrated very clearly; the fact that it hasn't happened before is not a demonstration that it cannot ever happen.

And last: Take care in trying to critique Grizzly Bear's choice of citations. Wiki is to be avoided as a sole and ultimate authority, but when it's used simply as a description of details (such as the structural categorizations that GB was showing), the information is verifiable. You risk writing it off and thus demonstrating ignorance at your own peril; the real critique of a Wikipedia source is whether it's accurate. In too many cases, it's not, but that doesn't extrapolate to all, and you've not demonstrated that it's inaccurate in this specific case to begin with. So don't write it off; address his point, not his source. Your text following your write off does neither; it merely makes an unsupported assertion that professional surprise at the collapses means that the collapses couldn't have happened. As demonstrated by not just the NIST conclusions, but also the Arup findings, the Purdue ones, and other organizations, it's accepted that it indeed occurred. Regardless of surprise.

Hi Grizzly Bear, I agree, but the sounds of the collapsing structure weren't picked up above the sound of people talking so here lies the overall problem.

Indeed. I picked up a Deering Goodtime Special recently. Sort of getting the hang of 3 finger Scruggs style. It's been a lot of fun.

Hi all,
Anyone who comes onto the Richard Gage rebuttal thread may well think we aren't even discussing my YouTube videos at all. Some arguments are not in either Gage's Blueprint for Truth OR my YouTubve rebuttal videos.
I request that we agree to:
1) Not engage in protracted debate on issues not in either Gage's video or my YouTubes. Those belong elsewhere on JREF.
2) To make it easier for everyone, make a quick referral to which video you are responding to (for example, "Gage says in his video that..." or "Chris's video #18 tries to explain freefall collapse of Building 7 but he's wrong because..." or "TruthShines911" said that Chris's video #18 was inaccurate but MIT Professor Nguyen Thun corroborates Chris's assertions in..."
This way newcomers to the discussion will know where we are... and frankly, so will I.
3) If someone launches off on a completely unrelated topic, let's all agree to tell him/her so and not respond to their assertion (no matter how tempting)... maybe even suggest a better place to take it, like the general 9/11 Thread.
Thanks all, I might have some time for actual responses later tonight too,
Chris Mohr

And yet with a complete absence of any of the audio, visual or physical evidence consistent with explosives.Thank for laugh(s).

If you look at the so called collapses you'll see, if you're perceptive enough, the towers disappear from the top down as floor by floor is completely demolished and WTC7 sinks from view as the lower floors were being demolished.
Do you have anything besides old, false, truther memes?All three smooth and even "collapses." A word to the wise and most of the rest here, damage and fire never, in the history of the world, have resulted in anything smooth and even.
Common sense told us the sun revolved the earth. Common sense tells us that people were burned at the stake in the Salem Witch Trials. Common sense tells us apes are the same as monkeys.It's common sense. That's why they call it common sense.
I note the conspicuous lack of "evidence" and "research" and "reason" in there.Good sense and sound judgment in practical matters.
