WTC Building 7 Explained

EdwardCurrent via YouTube

An expanded/updated version of my 2011 video “Building 7 Explained,” focusing on 7 World Trade Center’s construction. The tube-frame steel design explains why its collapse looks similar to a controlled demolition — thus creating a generation of modern conspiracy believers.

The animation at 5:00 is scale-accurate: The east face of the frame really did tip that much to the north (the smaller building shown is Fiterman Hall). Meanwhile, the west face appears to have tipped to the south. There is no evidence whatsover that the frame collapsed “into its own footprint.”

Addressing other top talking points:

“Thousands of architects and engineers disagree…” And many, many thousands more agree. I made comedy out of the generally poor professional qualifications of those who have signed the petition put forward by Architects & Engineers for 9/11 Truth: https://youtu.be/lpEnvGBfgnI

“You haven’t looked into the evidence…” Actually I have, because I used to be a Truther: https://youtu.be/UULUQfEQFuU

“A collapse like that due to fire would violate the laws of physics.” That’s interesting since NIST created a simulation that was quite accurate up to the last (and hardest to model) part of the collapse, using the program LS-DYNA, which — believe it or not — relies on the laws of physics to operate. If you don’t like the job NIST did, you can make your own simulation and see what happens — the construction and materials of the building are a matter of public record. In the meantime, feel free to point to one paper in a legitimate peer-reviewed engineering journal that supports this “violation of physics” claim.

“Professor Leroy Hulsey of the University of Alaska just released the results of a two-year study…” With funding by Architects & Engineers for 9/11 Truth, Hulsey and two graduate students computer-modeled two floors where NIST found that collapse initiation *might* have taken place, and found scenarios where the collapse did not initiate. The team did not attempt to model any other cases where the collapse might have initiated. Not exactly an exhaustive scientific investigation, but hey, they’re still seeking donations to keep this hope alive.

“You believe everything the government tells you.” The government in reality is fairly incompetent. And, you’re asking people to believe that this same government pulled off a perfectly executed secret operation AND has maintained this secret conspiracy for 16 years and counting, after the operation was carried out and with hundereds of thousands of people worldwide working to expose a cover-up. The skeptical person finds this to be a highly unlikely scenario. See: “How to Apply Occam’s Razor”: https://youtu.be/AQNxNeQ9cxw

“Witnesses heard explosions in WTC7 before it collapsed.” Lots of things explode in fires. Transformers, gas lines, fire extinguishers, fuel tanks, even pneumatic office chairs have been shown to explode in a fire. That’s very different from high-velocity detonations necessary to cut even one major steel column of a skyscraper, which would exceed 150 decibels a half mile away.

“You are obviously paid by the government to make these videos.” Thank you for demonstrating your standards for evidence that confirms your pre-existing beliefs.

“But military-grade super-nanothermite that no one knows anything about . . . .” Okay, we’re done.

 

What happened to 7 World Trade Center?

By Stuff They Don’t Want You To Know via YouTube.

During the attacks on September 11th, 7 World Trade Center was destroyed. But it wasn’t struck by a plane. So what happened?

World Trade Center 7: The Lies Come Crashing Down

Was the collapse of 7 World Trade Center actually a controlled demolition?

Brian DunningBy Brian Dunning via Skeptoid: Critical Analysis Podcast (2008). Read transcript below or listen here.

Today we’re going to point our skeptical eye, once again, at the events of September 11, specifically at World Trade Center 7, the building that collapsed after the twin towers for no apparent reason, in a manner consistent with a controlled demolition. We’re entering the weird wild and wacky world of conspiracy theories, men in black, deceit, doubt, mistrust, and delusion. But on which side?

First let’s be clear about what the two sides are, then we’ll examine the evidence supporting each of them.

The conspiracy theory states that World Trade Center 7 was a controlled demolition, an intentional destruction of the building by our government. The evidence supporting this theory is threefold: First, the video of the collapse and the tidy distribution of the resultant debris appear consistent with known controlled demolitions. Second, photographs of the building before it collapsed showed little or no damage to cause a collapse. Third, fire alone cannot destroy a steel building, and so the cause must lie in high-energy explosives. A great deal more information is put forward by the supporters of this theory as evidence, but it’s really only suppositions about proposed motives and observations of events perceived as unusual, and so is actually not testable evidence of a direct physical cause. This information includes government offices located in the building, the establishment of Giuliani’s emergency management headquarters on the 23rd floor, and portions of the government’s preliminary reports that openly stated that certain unknowns remained.

The competing theory is found in those very same government reports. The first, a preliminary report issued by the Federal Emergency Management Agency (FEMA) only eight months after the event, concluded that fires on the 5th through 7th floors caused the collapse, but infamously noted:

The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time. Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence. Further research, investigation, and analyses are needed to resolve this issue.

Three years later, the National Institute of Standards and Technology (NIST) issued a working draft of the complete theory, scheduled to be finished in 2008. (IllumiNuTTi Note: The National Institute of Standards and Technology (NIST) released their Final Report on the Collapse of World Trade Center Building 7 on November 20, 2008 [Web page here] [PDF file here]) This report states that the building suffered two major failures, either of which could have been survived on its own, but not in combination. The first failure was severe damage to ten stories of the south side of the building, dramatically shown in a single frame of video from an ABC news helicopter, which destroyed several major columns. The second failure was the fire, fed in part by diesel generator fuel from high pressure tanks, which proceeded unfought for seven hours due to a lack of water pressure, and caused terminal weakening in the remaining columns that were already overloaded from the loss of the initial columns. Firefighters noted a growing bulge between the 10th and 13th floors and major structural creaking sounds, and finally evacuated. Two hours later, the east wall began to crack and bow. The east penthouse sank into the structure, and eight seconds later, the northeast corner fell, bringing the rest of the building down on top of it.

No evidence of any explosives were ever found, but the conspiracy theory states that this is because the government took away all the debris before it could be independently tested. Since it’s normal for debris to be removed following any such destruction, this particular piece of information is too ambiguous to be given serious weight as proof of a conspiracy.
