message: Does anyone know what the overall weight (or mass) of the Towers were? I haven't read through the entire article so I don't know if it may already be in there, but I want to know what the weight of the structure was. I need the mass to calculate the Density, I can easily get the Volume from its dimensions, but the mass is currently unknown to me. So if anybody knows (or even has a rough estimate of) the weight, it would be much appreciated. --Hibernian 14:35, 13 January 2007 (UTC)

#Support but not for reasons of the nominator. This one doesn't seem so cut and dry. Maybe its because I've worked in the Financial markets so to me hearing the phrase "World Trade Center" alone doesn't equate directly to the Twin Towers, even after 9/11. Most major cities have a "World Trade Center" of some sort and they are commonly attached to the city they are located in. In regards to 9/11, I would say the unique identifier is the "Twin Towers" because that conveys the NY WTC alone. I can see valid reason to move it because leaving the title as it is, wrongly conveys that there was only one singular building called a "World Trade Center". 205.157.110.11 04:06, 30 January 2007 (UTC)

thread_title:  Editing request 

message: The previous reviewer appears to have abandoned the article after the prior hold, but since it was never delisted, I reviewed it.  Unfortunately, there are to many issues to consider extending the hold or passing it.  These fixes need to be done to achieve GA status.  My review is based on the Good Article Criteria at WP:WIAGA.
*Copyediting issues:
**The lead has some awkward phrasing.  The big problem is the description of the damage to each individual building; it doesn't flow well.  There is some sort of punctuation/run-on-sentance problem that needs fixing.
**The Film and media section is poorly written, unreferenced, and in violation of the good article criteria prohibition on trivia sections.  
*Referencing issues:
**Use of word "iconic" in lead needs reference.  I know it is iconic.  You know it is iconic.  Our opinion doesn't matter.  Find a reference that calls it iconic.
**First paragraph of design inovations is unreferenced
**Entire Engineers and contractors section is unreferenced
**First paragraph of Architectural criticism is unreferenced
**Observation deck and Windows on the World section is unreferenced.
**First paragraph of The other buildings section is unreferenced.
**Several paragraphs of the Rebuilding the World Trade Center section is unreferenced.  Due to the speculative nature of this section, referencing to reliable sources for EACH assertion must be scrupulous.
*Reference format issues:
**Inconsistent formatting of references.  Ideally, EACH reference should contain complete bibliographical information, such as:
***Author (if availible)
***Title of the work
***Larger work (if applicable)
***Publication information
***Date of access for webpages.
::If you would like, you can use the citation templates found at WP:CITET to help organize this information.  Also see relevent policies WP:ATT and WP:CITE for more information.
*Image issues:
**The use of the CNN image (Story.crash.sequence.jpg) is a problem.  First of all, it is incorrectly tagged, as the tag specifically states that it is to be used only, and I quote from the tag, for identification and critical commentary on the film and its contents".  This use is not doing that, and thus does not meet fair-use requirements.  Also, the use of watermarked images is highly deprecated.  Finally, the use of the image is unneccsary, as there is already a free image (the National Park Service one) in the article that meets the purpose this one is trying to.
**The fair use rationale for the image "New wtc.jpg" is a bit sketchy.  I would agree that the use of this image probably meets minimum fair use requirements, but the image is not correctly source (please provide a link to the original) and the rationale is non-standard wording.
I know it is a lot, but I would like to see this article be up to standard as spelled out in WP:WIAGA.  Please improve the article, and when these fixes have been made, please feel free to renominate it at WP:GAC.  --Jayron32|talk|contribs 03:16, 21 March 2007 (UTC)

I think it shows the towers in the context of the surrounding area in a nice way, as well as showing other buildings in the WTC complex, WTC7 in particular.  The image is also from approximately the same viewpoint as the rendering of future construction.  I'm happy to make the image available with the appropriate license if the editor would like to include it.

:We have discussed why the fair use images are not allowed.  Wikipedia policies have not changed.  As for the other images, it's great to have new images.  I also removed two fair use images - new WTC image and Windows on the World, since I really don't think we have necessary rationale for using them, per WP:FU.  Despite removing a couple images, I'm slightly concerned about the number of images though, and possible overcrowding.  I moved the construction photo back to go with the planning and construction section.  Other images should try to match the topic of the text (e.g. the 9/11 picture located next to that section of text). --Aude (talk) 12:01, 17 July 2007 (UTC)

message: I've never really know who "owns" big giant skyscrapers like this (or who will own the to-be-build Freedom Tower). Is it the city? The state? An individual? A company? When the space is rented out, who gets paid? Who's the "landlord?" The port authority owns the area, but do they own the building, too? What about other buildings in NYC: does someone there own the building and the plot of land it's on? It is the same in all cities? When the WTC collapsed, did people lose their investment into the building, or do I have it all wrong?
I'm just a little curious about the process, so if someone would care to enlighten me, I'd appreciate it! └Jared┘┌t┐  11:54, 18 July 2007 (UTC)
replies: text: The Port Authority of New York and New Jersey owns the land and the buildings, and built them.  Though, in early 2001, the Port Authority finally worked out a lease with Larry Silverstein (he competed against a bunch of other companies - Boston Properties and some others).  So, Larry Silverstein served as the landlord.  The WTC is unique, in that it was built by a quasi-government agency.  Pretty much all other large buildings, including the Empire State Building and Chrysler Building, were privately built, privately owned, and privately managed. The WTC, like all those other buildings, was insured.  Though, I think it was somewhat underinsured, and it's costing quite a bit more to rebuild.  Costs are being covered by insurance, Liberty Bonds, and the Port Authority has the ability to take out tax-free loans or financing.  With most projects the Port Authority has built (e.g. various bridges and tunnels where tolls are collected), they have been profitable for the Port Authority, allowing it to pay back the loans with no problems.  The WTC was supposed to be profitable, but not sure it was or will be now. If this is inadequately explained in the article, I can try to work on it in the near future. --Aude (talk) 14:12, 18 July 2007 (UTC)

In recent years, the Petronas Towers in Kuala Lumpur, Malaysia were built by Petronas, a Malaysian owned oil and gas company.  Then Taipei 101 was built (doubt by the government, but some private developer), and now Burj Dubai in Dubai (under construction) I think officially surpasses Taipei 101 this month to be the tallest. I'm just guessing that the United Arab Emirates and/or Dubai governments are helping back that project, but won't be owning it in the same way the Port Authority. --Aude (talk) 15:16, 18 July 2007 (UTC)

As for Unitied airlines 93 was not shot down but brought down by the hijackers when the passangers of flight 93 fought back and stopped them. "The 9/11 Commission reported that authorities suggested that U.S. air defenses had reacted quickly, that jets had been scrambled in response to the last two hijackings and that fighters were prepared to shoot down United Airlines Flight 93 if it threatened Washington"."In fact, the commission reported a year later, audiotapes from NORAD's Northeast headquarters and other evidence showed clearly that the military never had any of the hijacked airliners in its sights and at one point chased a phantom aircraft — American Airlines Flight 11 — long after it had crashed into the World Trade Center, according to CNN.com". "Furthermore, the closest fighters were about 100 miles away and were unarmed.

message: I continually revert the classification of the status of the World Trade Centers from "destroyed" to "demolished". Our source is Emporis. Listing it as anything other than what Emporis has violates the Wikipedia "no original research" policy. Yes, the buildings were destroyed, not taken down during a controlled demolition, and you can mention that in the article. However, if we are going to use Emprois's building classifications as a source, adding classifications is considered original research.
These are Emporis's classifications for buildings.
- Completed
- Demolished
- Under Renovation
- Under Demolition
- Under Construction
- On Hold
- Approved
- Never Built
- Proposed
- Vision
There is no "destroyed" category. The World Trade Centers are listed as demolished, but there is a link given to information about the 9/11 attacks. If we're going to use a source, we must use the information that the source gives us. Here's the page of "demolished skyscrapers in New York City".
http://www.emporis.com/en/wm/ci/bu/sk/li/?id=101028&bt=6&ht=2&sro=1
The status is listed as "demolished". It later mentions that the buildings were destroyed, like this article does, but the status uses only their own building classification system.

The World Trade Center article has a mistake.
Under the heading "Structural Design", this statement is correct:
The perimeter columns supported virtually all lateral loads, such as wind loads, and shared the gravity loads with the core columns.
Under the heading "Design Innovations", this statement is inaccurate and contradicts the above correct statement:
The core supported the weight of the entire building and the outer shell containing 240 vertical steel columns called Vierendeel trusses around the outside of the building, which were bound to each other using ordinary steel trusses. In addition, 10,000 dampers were included in the structure.
The fact is the core columns did not support the weight of the entire building. The core columns shared gravity loads with the perimeter columns.
Someone should correct this.

message: Now that GA is established, the next hurdle in advancing the article involves tighter constraints on what makes for clear writing. I think the lead section is gummed up with years of piecemeal editing efforts by various participants; it needs a firm hand to cut some detail out. Material cut from the lead would, of course, be restored in the body of the article. The problem before you guys is this: What detail stays in the lead and what doesn't?
I've just poked at it somewhat to try and get the ball rolling. I'm no fan of a string of alternate names right up in the first sentence as that arrangement tends to obscure rather than reveal. I moved the three alternate names down chronologically to where the building complex was first finished.
Beyond that, you guys should decide if all the names, dates and organizations need to remain above the fold. I imagine a fair portion could be moved south. Binksternet (talk) 04:16, 3 December 2008 (UTC)

it is clear from all construction photos and articles about construction of the world trade center towers that they had a steel core. here are a few references all saying it was a steel core. newsweek  engineering.com  skyscraper.org berkeley  and a photo of the steel core under construction.   —Preceding unsigned comment added by Fizzbot (talk • contribs) 22:45, 25 December 2009 (UTC)
replies: text: According to www.engineering.com and skyscraper.com, it was a "reinforced steel core". What kind of material was used to reinforce the steel? According to other sources, concrete "walls" or "infill panels" have been used.  Cs32en  15:06, 26 December 2009 (UTC)
