911 inside job

My opponent has not explained how the buildings collapsed as not even NIST can, firstly I will start by debunking some of his claims.People Heard ExplosionsNot only did normal people hear explosions but firefighters did , like con said firefighters are experienced in hearing explosions from office fires etc, however there are firefighters who are adamant that the explosions were from bombs and not explosions .(1)Also there were witnesses who witnessed explosions in the lobby far below the fires occured. (2)In the basement (3)In building 7 before the towers collapsed (4)Did Larry Silverstein Admit To "Pulling" One Of The Buildings?While I never took this as evidence .WTC7 Wasn't Hit By A Plane, Why Did It Collapse?Neither was building 5 or 6 yet both buildings suffered far more debris damage (5) and fires (6) than building 7 but yet did not collapse straight down with moments of free fall acceleration something impossible due to newtons third law of motion.It is not conspiracy theorists yet thousands of architect and engineers who question the collapse of building 7. (7)NIST explanation is that fires caused the building to collapse not the debris . NIST cannot explain how the building collapses as there computer simulation does not match observed events. (8)It therefore isnt a valid scientific hypothesisWitnesses (9) and video evidence of clearly seen explosions seen in building 7 seem to suggest otherwise.What Do Explosive Experts Think?Nowhere inthe paper does it conclude that the buildings could in no way have been a controlled demolition rather it is discussing some points about the controlled demolition hypothesis .The 'experts' are only commercial controlled demolition experts and in no way are exposed to the type of classified technology that the insiders would have had access to .This includes Nano thermite which is like RDX on crack. 'A smaller ,Nastier and cheaper explosive""(Los Alamos national laboratory)Also the possible use of Linear thermite charges(10) or cutting device would make a thermitic reaction a lot more effecient in destruction of steel girders. Homemade thermitic charges made by a 911 truther and engineer has proved absolutely that thermite or thermate is effective in the destruction of steel member present in the wtc doing experiments What About The Thermate/Thermite Supposedly Found?An exusable mistake by Con regarding his lack of knowledge of chemistry , the claim by Dr Steven jones was never that because those chemicals were present in the wtc it was evidence of thermite.The claim was that iron spheres were found, indicating that they were previously molten as surface tension causes spheres to be formed when in the liquid state, such as a drop of water.These spheres have the chemical signature of thermite.The only way to make iron spheres with the chemical signature of thermite is is a thermitic reaction because all these chemicals are melted together at the same time and has nothing to do with background dust.Could the Twin Towers Have Collapsed The Way They Did?A bold statement by Con who has no engineering background, The problem with the progressive collapse theory is that all of the material is expulsed horizontally outwards as dust and debris and steel beams , the material does not progressively stack up or avalanche .If you dont believe me watch the video of the towers collapsing and tell me if you think its progressively collapsing.(12) One would expect to find concrete at the bottom of the towers ,yet all of the concrete was turned to dust, so how can dust crush intact concrete below.Note in the video waves of explosions travelling faster than the acceleration of gravity 9.8ms which you would expect from a gravity driven collapse(13)Also explosive flashes are seen in the footage.(14)Conclusion- NIST does not offer an explanation for the collapse of the towers and neither does CON , the best they can do is the initiation of collapse and provide no emperical evidence for the initiaiton of collapse for building 7.Nor do they offer an explanation for the 3.9 seconds of free fall acceleration of the building which is impossible if there is no resistance due to Newtons third law of motion.(1)http://www.youtube.com...;(2) http://www.youtube.com...(3)http://911research.wtc7.net...(4) http://www.youtube.com...
