First off, much like how cars are engineered with crashes in mind, when large towers are designed there is a considerable effort put towards managing how the building will fail. Being that you don't want a 100 story building to tip over and spread its destruction over many blocks, most of these buildings are designed to collapse inwards and fall ontop of itself. Secondly, being that the weight of materials on tall towers is the primary stress on these buildings they're designed with a relatively small margin of error. When you (effectively) have the weight of dozens of floors falling 1 story because the structure beneath it has given way due to a fire damaging the structural integrity of the building, the force is so much greater than what the building can handle that every story will collapse as they experience this force. |
Fair enough, but explain to me what happened to the massive steel cores in the twin towers. Not to mention, if your pancake theory is correct, there would be a massive stack of floors at ground zero, but instead everything was shreded to dust and small steel shards. Also, the contents in the building would have, for the most part, been trapped inside the building when it "fell," yet dust, paper, and debris was all over lower Manhattan.Where was this huge mass on top that was pushing its way down through the middle of the towers (which is the path of GREATEST resistance?) It was non existant. The towers essentially tore themselves apart.
I will repeat this again... A Steel reinforced concrete building CANNOT, I repeat, CANNOT implode at the rate of free fall, without explosive devices of some kind being planted. The towers came down in 10 seconds roughly, meaning the buildings came down at a rate of TEN floors per SECOND. Imagine your house. Then stack 4 more of those on top. Then add thick steel reinforcement, including a massive steel core holding them up. You bilnk, and it is all gone, pulverized.. In ONE SECOND. Do you really see such a scenario occuring without explosives?
I am just completely baffeld that here in 2011, where we are supposed to be semi-evolved and intelligent human beings, and yet people can look at that footage of the freefall implosion, explosive squibs running down the building, pyroclastic clouds, all that - and believe that is simply gravity bringing it down. Just shows how frighteningly brainwashing the mainstream media can be..
