I found this interesting...
John Skilling, one of the two chief designers stated:
Frank A. Demartini, on-site construction manager for the World Trade Center, stated on January 25, 2001::
“The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC-8 ) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.”
So these two buildings failed in exactly the same way from impacts they were designed to absorb.:
The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting.
The designers did, and were apparently wrong 2X.Yeah there have been demolitions and you can say that it resembles a demolition because of a, b, and c, but you can't say that it wasn't the aftermath of the aircraft, because you have no idea what the aftermath should be.
Office fires cannot generate enough heat melt steel, nor can aviation fuel, which is why no large steel-frame before or since has ever collapsed due to fire alone. That observation asks more questions than it answers.
I won't argue that! I wish there had been more forensic investigation of the actual material involved, though.
I share this frustration. Even the official 9/11 report states that given the inputs, the towers shouldn't have fallen, so they had to adjust the inputs in order to make them fall on paper. Take the Pentagon crash for example. I find it difficult to believe that out of all the cameras in the area that 4 frames of poor quality parking lot video is all that exists. The powers that be could lay this issue to rest by simply releasing the video. To keep it to themselves only fuels the conspiracy theorists.Every single argument I have seen is ripe with bullshit and fallacies, and yes, it's going to take more than that to sway my belief that the whole thing is not an elaborate ruse to fool America that somehow, nobody has spoken up about yet. I question plenty, and I have given your side plenty a chance, but you have yet to provide substantial evidence that has an actual solid foundation.Comment

Yeah, I read that too. So far, that's the only "evidence" backed by credible sources. You're going to need more than that, sorry.I found this interesting...

Did you even read what I said?Office fires cannot generate enough heat melt steel, nor can aviation fuel, which is why no large steel-frame before or since has ever collapsed due to fire alone. That observation asks more questions than it answers.
Suspicion is different than absolute knowledge. Yeah, maybe it's a little fishy that that's the only thing that's released, but you have no clue why that is, and you're never going to get the truth regarding that, only speculation.I share this frustration. Even the official 9/11 report states that given the inputs, the towers shouldn't have fallen, so they had to adjust the inputs in order to make them fall on paper.

I agree with you... "melt" is not possible.
But take a small piece of steel pipe and heat it in a fire... It won't melt, but it will certainly be much easier to bend or damage due to the higher temperature.
Now let that happen to the supporting steel in the building... Then add in the wreckage now distributed unevenly across the floors and the collapse in some areas of the floors due to just the impact. All of those together and I think you have the ingredients for a structural failure.
But that just my opinion.Comment

Evidence for what? I wasn't suggesting anything. You assume an argument where none exists.
Sure! But let's stay with facts. Just because a metal softens, it doesn't mean failure is imminent, and since there have been plenty of observable fires in similarly constructed buildings that did not result in collapse, the question of what combination of factors caused the collapses remains open. The designers certainly thought the building would deal with it just fine, even after a plane impact, and they likely knew more about building design than any of us. ;-)
Fishy? We got video of the plane that went into the Hudson recently-and I hope the DC area has better surveillance than Manhattan! I toured the few Pentagon areas accessible to the public pre-9/11 and everywhere you looked there were cameras. The nearby hotels had them. The building itself had them at the corners-not to mention every bit of the grounds appeared to be monitored......and that weak-ass four frames is all they got? If that's true (I suppose it's possible) then whoever was paying for all that surveillance got gypped!
As is the case with all of us. :-(Comment

I just want to address this point right here.

First of all lets further examine the point that the buildings were designed to take the hit of a 707.
The senario invisioned in which a jet liner would strike the towers is this:
Its a foggy night and a plane is on approach to Kennedy airport. The plane is flying slow ~200 Knots with LEVEL wings and the pilot doesnt realize hes flying into a building.
The desginers never invisioned somebody purposely flying a plane into one of the towers
It was a very different story on Sept. 11. The planes came in rolled slightly, this meant that they took out more floors than aniticipated from an impact. The planes that hit the towers were much larger than a 707. This also meant that they took a larger chunk out of the building system than invisioned.
Aviation fuel has changed slightly over the years inorder to promote better burn and efficiency. This means that it is desgined to burn hotter! The buildings fireproffing was stripped due to the force of the impact.
Ohh and yes, the outer shell and the core of building were very strong together. But lets examine the actual desgin of what failed...the A frame trellis that make up the actual floors. It is a naturally weak design when heated because it buckles and twists when introduced to intense heat. A heat that no office fire could possible generate...the heat of burning jet fuel. So one of the top floors trellis failed and hit the floor below it, the already weakend steel of that floor collasped and there you go...complete failure of the building.
And before you conspiracy jackasses question my credibility I am an Aeronautical Engineer and my father is a Construction Manager in Manhattan with degrees in both Civil and Mechanical Engineering...he had a meeting on the 87th floor of tower 2 at 8:00 am on the morning of sept 11, 2001.
It was the one day my family thanked God for traffic on the LIE.
Ohh and Canada also gave us William Shatner.Last edited by E88 Owner...But E30 Fan; 09-12-2009, 03:57 PM.
