I heartily commend OffG for hosting their 9/11 series; most sites tend to be polarised as either pro or con – it is a rare opportunity for both sides to air simultaneously. I also commend Jerome and Carroll for largely driving one side of the argument; and in particular to Carroll for his diligent and detailed research. I concur that the jury is still out regarding nano-thermite and that further studies are required to verify this. This, in itself is in line with the Harrit et al paper. 
In agreeing that Carroll has done valuable work and broadened the debate, I however also believe that he then goes too far in his hypothesis. Where I begin to diverge is in the production of what I would term an “If Chewbacca lives on Endor – you must acquit”;  a type of non sequitur argument with a fallacious conclusion – that no thermite = no CD = fire collapse.
To my mind, he has at most highlighted that the mechanism of collapse needs further research, but has not proven irrefutably that fire collapse is the simplest, and therefore only logical, conclusion. For one thing, if answers can be found, they must account for all the known factors.
Unless I misunderstand him, as a method of collapse Carroll posits the ‘self-discovered’ chimney effect. As far as I am concerned the ‘flue effect’ is well understood by any designer of low or hi-rise buildings; and buildings are assiduously designed to prevent it. In one of his posts states (in 7WTC):
A chimney effect in the shaft of the dislodged elevator reported by Mr. Jennings.
Here I detect a glaring omission; which I can only conclude as to be conscious in one so versed in the study of 9/11 (“I have forgotten more about NIST than most people know”). Viz – that Barry Jennings also testified that a large internal explosion left the lobby of 7WTC ‘in total ruins’ (the timing of which would be consistent with this  NIST FOIA video shot around 10:15 a.m).
That’s how Carroll posits his ‘chimney’ – dislodged elevator and (I presume) fire doors; but fails to mention the elephant in the room – that this dislodging was caused by an internal explosion or series of explosions that occurred before the North tower even started to fall. Curious. (For more detailed analysis see  )
I am presuming that most readers are at least as well informed about Barry Jennings as Carroll; so I will forego a wider discussion of the timeline. I should however briefly set the scene.
Barry Jennings was formerly deputy director of the Emergency Services Department of the New York City Housing Authority. When the first plane hit the North tower (8:46 am), he (and Michael Hess, the New York City Corporation Counsel.) headed to the Office of Emergency Management’s (OEM) Emergency Operating Centre on the 23rd floor of WTC 7 (the so called ‘Mayors Bunker’). When they got there, it was empty (Where’s Rudy? By his own admission he had been and gone – he claimed at the time he was told the North tower was “going to be in imminent danger of collapse”. How did he know that before 9am?) As they attempted to exit the building, they were blown back by an explosion beneath them (the 6th floor landing collapsed under them) and they were forced back up to the 8th floor were they were trapped for the rest of the morning. (For the first interviews they gave see  – if you go to 2:32 in this (originally released by NIST) you can see Hess trapped on the 8th floor and clearly hear him say “an explosion”) (It is important to note that the timing of the UPN 9 News interview places Hess around half a mile from WTC7 before noon.)
No evidence of explosives (Jerome’s constant refrain); a collapse solely attributable to fires? – here I present the inconvenient, yet seemingly irrefutable evidence of two credible witnesses, both from the OEM, trapped by an explosion inside WTC 7.
Why is this not central to our discussion? Why was this and other evidence of explosions  ignored and not followed up?
Here is where history diverges, facts become blurred and opinions polarised. For these two men, briefly united by this act of terror; the eventual outcome and consequences could not have been more different.
The distortion of this testimony has been traced to Rudy Giulianis self-deprecatingly titled 2002 book ‘Leadership’ . The standard debunk is to dilate the timeline, conflate the earlier reports of ‘explosions’ with the North tower falling and attribute the destruction of the lobby to falling debris. I for one am not buying this, not least for the inconsistencies in the new timelines  but simply because when people start to try and distort evidence I get suspicious.
Timelines, especially in a disaster, can be conflicted I agree, but a fact to note is that both men were in one of the northside (NE) stairwells (see the Cantor Structural Drawings in the footnotes of[4) any falling debris would be on the southside (SW corner) – timings aside – is it conceivable that ejecta passed all the way through the core of the building to take out the 6th floor landing from underneath them? If it wasn’t falling rubble, what trapped these men that morning?
Because when I was on the stairs I saw “NORTH SIDE”. All this time, I’m hearing all types kinds of explosions. All this time I’m hearing explosions.
[Barry Jennings (Excerpt from the transcript of “Loose Change – Louder than Words”)]
Yet NIST also followed the Giuliani line; ignore the destruction of the lobby and extend the timeline to have the men being rescued at 12:10 to 12:15pm (bear in mind that Hess was interviewed half a mile away at the latest at 11:57 ). This could conveniently place them in the stairwell at 10:28am when the North tower fell. This fallacy was ably supported by our very own national propaganda vehicle – the BBC (“The Conspiracy Files: 9/11–The Third Tower” – available on this site) This contained an edited version of a Barry Jennings interview neatly cut with a ‘reassuring’ voice over:
At 10:28, the North Tower collapses. . . Tower 7 takes a direct hit. . . Early evidence of explosives were just debris from a falling skyscraper. 
That could have been the end of the Barry Jennings story: edited out of history; anonymously included in NIST – his testimony rewritten in support of the official version (: read – Official Story – Point 8; Footnote ); his narrative carefully crafted by the BBC to make it seem he was confused and disorientated. Were it not for Dylan Avery we would never have heard the other side. [<a href= #thirteen13]
The BBC documentary first aired July 6, 2008; NIST’s Draft for Public Comment – was released at a press briefing on August 21 (“Dr. Sunder – the mystery of the collapse of WTC 7 solved – “It did not collapse from explosives or fuel oil fires.”) Tragically, two days before that Barry Jennings died.  Whether or not this was in ‘mysterious circumstances’ is a moot point.  It was none the less convenient for NIST.
Nor did the BBC waste the opportunity to air a second version of the “The Conspiracy Files: 9/11 – The Truth Behind the Third Tower.” (at the end of October 2008.). Despite not even being mentioned in the first version: Michael Hess was now the star. The standard debunk (part 2) is to conflate the original testimonies with a revised ‘in hindsight’ version (which no one could now criticise). Hess, whilst admitting that in 2001 he had “assumed that there had been an explosion in the basement,”
I know now this was caused by the northern half of Number 1 [the North Tower] falling on the southern half of our building,
That this would echo the Giuliani line  should be of little surprise: Michael ‘I’m with Rudy’ Hess was not only his close personal friend – but in 2002 he was one of the founding Partners and Vice Chairman of Giuliani Partners LLC.  Trading on his former bosses reputation as ‘Americas Mayor’, he has done quite well out of 9/11. Unlike Barry Jennings. I ask – credible witness or corporate shill?
To my mind then, Barry Jennings testimony stands. Apart from the facts, collation of data and cross referenced chronology in the references I have provided: my conjecture is – if he was lying – why bother to try and obfuscate his story? Let it stand and be discredited. I should perhaps add that NIST has so far refused any FOIA requests to release the interviews both men gave in 2004: on the grounds that they are ‘not directly related to the building failure.’  My conclusion is therefore, thermite or not, we need to be looking for an explosive event to at least partly explain this mystery.

This interview was not included in “Loose Change Final Cut” at Jennings’ request, after he had, he said, received threats to his job. But after Jennings participated in a BBC documentary about WTC 7 (“The Conspiracy Files: 9/11–The Third Tower”), Dylan
Avery, who had conducted the interview, put it on the Internet as “Barry Jennings Uncut.” https://www.youtube.com/watch? v=OmeY2vJ6ZoA
 A lot has been made of this death, in particular the beneficial timing of it (for NIST etc), the implication being that he was ‘suicided’. I am not saying that. If you read the comments on  there is someone who purports to be Jarel Jennings; Barrys eldest son. He says Barry died of a cardiac arrest (whether this was related to toxic dust inhalation – he doesn’t say.) Disinformation – I don’t know? His Facebook page doesn’t give much away (there is another Jarel Jennings, whose father Barry is very much alive!). There is already enough mystery around the collapse of WTC7 without trying to make it more sinister.

 Jennings and Hess testified to NIST in 2004, but this testimony was never released and FOIA requests have been declined. David Ray Griffin cites one such request: “NIST declined on the basis of a provision allowing for exemption from FOIA disclosure if the information is ‘not directly related to the building failure.’” Letter of August 12, 2009, from Catherine S. Fletcher, Freedom of Information Act Officer, NIST, to a FOIA request of August 8, 2009, from Ms. Susan Peabody, for “[t]he complete texts of NIST’s 2004 interviews of Michael Hess and Barry Jennings, which are cited in NIST NCSTAR 1-8 … , 109, n.380, as ‘WTC7 Interviews 2041604 and 1041704.’” In: David Ray Griffin, “9/11 Truth: The Mysterious Collapse of WTC Seven,”
