Thanks for your answer. Appreciate that you replied, I see you looked up references. As you reference "hours talking" and "a decade and a half of debunking", likely you're over this and impatient - hopefully I can understand your points quickly.

For my part I certainly had the impression that thousands of engineers and architects were quite convinced that there was a controlled demolition following the plane crashes. Please note that I didn't take any political conclusions from this and would be interested in just sticking to the building structural facts - whether there was a controlled demolition in the opinion of structural engineers and architects.

1. When you write "one of the schools that did the actual research you're claiming was false", what research are you referring to? I didn't reference any study nor have one in mind, I'm a bit confused here.

2. From your last sentence, I think overall you're saying:

"I am certain that following the plane crashes no controlled demolition led to the collapse of the buildings. The 2270 people who signed the petition are not qualified architects. Qualified architects do not claim it was a controlled demolition (let alone obviously one.)"

Can you confirm this - is that right?

Besides these two points of clarification, I'll try not to waste more of your time. Thanks again for the replies.

I am kind of weary making a public statement about this subject, a controlled demolition would have been a crime against humanity. Unlike tedivm I do not claim any authority on this subject. During my teenage years I spent a lot of late nights just surfing the web and researched the 9/11 building collapse quite thoroughly at one point. I can also think. I came to the conclusion that, due to the structural design of the twin towers, if you fly a plane into them a collapse of the kind that was witnessed on the 11. September 2001 is the consequence.

I'm fine with listening to experts. (Of course this is what "Architects and Engineers" purported to be. As detailed by other comments, no, that group is not comprised of architects and structural engineers, which I didn't know.)

Do you really mean "weary" (tired) or "wary" (cautious)? If you are wary about making a public statement you can reply with an email (or write me at mine) I have just 1 or 2 remaining questions. I don't really want to clog this thread any more.

> "The 2270 people who signed the petition are not qualified architects. Qualified architects do not claim it was a controlled demolition (let alone obviously one.)"

No, this isn't what he is saying. What he is saying is "Of the 2270 people who signed the list, only 30 claim to be structural engineers".

The list is actually 2,750 now - anyone can sign it - the vast majority self-report as architects or non-structural engineers (for some reason, many claim to be aeronautical engineers?). For obvious reasons we don't use architects, or aeronautical engineers, to analyze the behavior of steel girders in the presence of fire.

Of the 30 who claim to be structural engineers, only 14 claim they are structural engineers who work on buildings, and of those 14, only one claims to work on high-rises.

TL;DR: One structural engineer with experience of high rises is on the list. And, and I'm going to write this in all caps: HE DOESN'T CLAIM HE THINKS IT WAS EXPLOSIVES!! His official statement is this:

> There seem to be a lot of unanswered questions and it would serve the greater good to re-open the investigation and do a more thorough job to remove any doubt.

You can easily verify this yourself by just going through the official list, here: http://www.ae911truth.org/signatures/ae.html#:/signatures/xm...

You've written 6 paragraphs which mean exactly "Qualified architects do not claim it was a controlled demolition (let alone obviously one.)"

You're right I'm making the same point several times, I'm sorry if it gets repetitive. I do it to try to highlight the point from several angles and to reduce ambiguity.

That said, I didn't intend my 6 paragraphs to mean "Qualified architects ..". Architecture is a discipline concerned with aesthetics, it deals with the design of spaces and how humans interact with them. It does not deal with the structural integrity of those spaces; this is why architectural firms employ and contract structural engineers, and why building plans carry separate architects and engineering seals.

An architect (and you'll note I'm making the same point a second time) is as qualified to make comments on the structural safety of steel girders as, say, an anthropologist, or a chello player.

So, and now I'm making the same point a third time: No, I'm not saying "qualified architects do not claim it was controlled demolition"; because there is no such thing as an architect who is qualified to assess that. What I'm saying is that there are 30 structural engineers on the list, and that among them there is only one who has relevant experience, and he is not making the claim that it was controlled demolition.

OK, "qualified structural engineers do not claim it was controlled demolition." (let alone obviously one, let alone thousands of them saying so.) Fair?

As evidenced by your previous comments in this thread, had he put it so succinctly, you would have asked for more clarification.

I'll put it in one sentence: "9/11 truthers are just as purposefully ignorant and ill-informed as climate change deniers and no longer deserve the time and effort of the mentally capable to rehash a conspiracy theory that is so thoroughly and completely debunked."

Thanks, but I really only care about what structural engineers think. (Also as evidenced by my previous comments.) So no, I don't have any followup.
