Sophistry. How in God's name can "in that area" be taken as anything but? Why would the speaker single out that area where the Chief was standing and apply that description if it wasn't unique relative to the rest of the site?
First of all, greetings again, edmundus. As you know, I appreciate your contribution to this thread, as should all posters here.
Now, about your use of the word 'sophistry.' I think that is inaccurate here. What I am, in fact, doing is drawing out inferences of meaning associated with what the witnesses have said. While you are not required to agree with the inferences, and I'm not asking you to do so, I will say that I have taken pains to only infer that which has a reasonably good chance of being consistent with what the various witnesses have said.
It is normal and natural, I think, for people to disagree about which inferences are accurate and which aren't. You and I obviously differ as to what inferences should be drawn from the statements, but that is fair game.
Now, because you contested the inferences that I drew from Edward Cachia's statement, I went back and re-read that statement again. In it, I found this little gem:
"As my officer and I were looking at the
south tower, it just gave. It actually gave at a
lower floor, not the floor where the plane hit,
because we originally had thought there was like
an internal detonation explosives because it went
in succession, boom, boom, boom, boom, and then
the tower came down."
Separate and apart from that little ditty, about which I make no further comment, let alone inference

Cachia uses the word "area" 11 times in his statement.
It is clear that Cachia took refuge in a garage on West Street when WTC 2 was destroyed. He describes in reasonable detail what he experienced there. His first use of the word "area" pg 8 was used to say they needed to regroup elsewhere than the garage. I think it fair to say that the first 4instances of his use of "area" referred to the garage he was in.
Now, the use of the word "area' to describe GZ was the 5th usage. As you noted, it is at pg. 12. Also in the same sentence, reference is made to WTC 2. So it may be that by area, Firefighter Cachia meant to refer to the area where WTC 2 had stood.
Hear this: If that is the area that was 1-2 storeys, then that is, indeed, signficant, in my opinion.
How much clearer does the statement have to be?
It needn't be any clearer at all. This witness is an important source, taken at his word.
On the page before that quote, he references the North tower as just having fallen. That would place the timeframe well before WTC 7 collapsed.
I agree with your assessment that he does not appear to be discussing WTC 7.
As far as saying "one of the few small stacks of debris that were higher than 1 storey": That's an assumption, unsupported by evidence, that there were only a "few small stacks of debris" that can be characterized like that.
It's not exactly an assumption. At this point, I think I've posted up at least a dozen photos that tend to show GZ was, for the most part, 1-2 storeys. It's not as though I'm makking this up. I'm not. Granted, posters here don't agree with my interpretation of the photos, but I've posted them and explained what I think they show.
Calling that sophistry doesn't do it justice. Weldon was not referring to a flat area and wondering where the pile went, he was describing a 7 story pile. He said "... because there was only 7 stories of piles" in reference to the Twin Towers, which were 110 stories tall. He was indeed describing much debris underground... and how there was only 7 stories left.
On top of that, this right here is a witness who's statement supports the posts earlier about debris underground accounting for more than the single story of debris you claim exists.
You and I disagree sharply on Weldon and I'm not sure what we can do about that other than note that it is a disagreement.
And furthermore, towards the issue of underground damage:
Here we may need a diagram to help us out.
The subway and the PATH railway are not one and the same. We may need another poster to assist in determining where the subway tracks actually are. It is not clear whether they actually run under GZ. We know the PATH tracks are underneath GZ and we also know, from the photos I posted, that neither the trains nor the tracks were damaged. Weldon clearly says he went into the Rector Street Subway. Rector Street is some distance away, but that might refer to the line, and not to where he entered. The diagram above shows a subway outside of the confines of GZ. He says he ran into a concrete wall, which does not sound like debris. I wonder if that was the bathtub? I said "I wonder" I do not know and if someone else does, they can post it.
Thje remainder of your post just highlights other areas where you do not agree with me and I do not agree with you. However, disagreement as between you and me does not equal refutation. You haven't refuted anything. All you have done is offer a different interpretation, based on your own use of inference; or sophistry if you still prefer that word. In any event, your process here is no different than mine.
