This thread is to expose Christphera as someone lying and fabricating stories to back up his claim that the World Trade Center Towers were built with explosives in place to be demolished later. Central to this wild claim is that the World Trade Center Towers did not have a steel core but instead was built with a concrete core filled with explosives. While construction pictures, news articles and engineering universities all show that the WTC Towers had a steel core Christophera's sole evidence seems to be a handful of poorly researched articles and blurry pictures from long distances. Most of what he claims is concrete is shown to be made of steel when shown from other angles or at other times in the life of the towers. Christophera's story changes continually on the details of where exactly the core is located, how thick his fictional concrete core is. He regularly simply fabricates claims such as "the cores were radically different because tenants complained" when in fact this is completely false and in fact impossible considering the second tower's construction was already well under way when the first tower was completed and occupied. so lets start by showing some of the proof for a steel core. i will try to keep the first post of this thread updated with any new info. Written Evidence and Statements: "For a combination of historical, cultural and economic reasons, tall, concrete-core buildings dedicated to office use are unusual in New York, where builders prefer the wallboard-enclosed cores with steel frames that Mr. Robertson pioneered in the trade center." New York Timeshere "Engineers are still debating whether the Twin Towers' unique structure should be credited for surviving the initial crashes, or blamed for collapsing in the subsequent fires, or both. But the point is that it was unique, utilizing closely spaced columns connected to a steel core by relatively lightweight floor trusses. " NewsweekNewsweek.com "Each of the towers, more than 200 ft. wide on each side, contained a central steel core surrounded by open office space. Eighteen-inch steel tubes ran vertically along the outside, providing much of the support for the building" Time Magazine. TIME.com "The twin towers were the first supertall buildings designed without any masonry. Worried that the intense air pressure created by the building's high speed elevators might buckle conventional shafts, engineers designed a solution using a drywall system fixed to the reinforced steel core. " engineering.comENGINEERING.com "Like many high-rises built in the 1960s, the Twin Towers were constructed with their weight distributed between a hollow steel core (containing services like elevators) and steel columns around the perimeter, maximizing open floor space. Many believe the older high-rise design, in which steel columns are often encased in concrete, is more fire resistant. “A lot of people have told me, ‘You should have used more concrete in the structure,’” said Robertson. However, his chart plotting the strength of steel vs. concrete at various temperatures showed that at the incendiary levels that raged in the towers, the two materials become similarly weak." Berkeley 04.17.2002 - World Trade Center remembered "Yamasaki has switched from concrete, his favorite medium, to steel because of the sheer height of the towers, and instead of having the weight of the structure carried by the frame and the elevator core, the great steel columns of the exterior walls will support it." Time Magazine article from 1964!! Art: Onward & Upward - TIME EVIDENCE FROM CHRISTOPHERA: Photo Evidence 1: Christophera claims the following photo shows "elevator guide rail support steel" topped by "butt plates" instead of the steel core. He has yet to provide any source for this information. In response we can see that his "butt plates" are actually where the steel beams connect to the steel core columns. We can also see that structural steel is connected his "elevator guide rail support steel". Christophera also claims the butt plates are too weak for a connection but here we can see the columns are welded.
