9/11 Revisited: Were explosives used? The answer apparently is YES!

 I was just looking at some slow motion videos of the 3 buildings collapsing on 911.  I watched university professors and physicists talking about the collapse.   They agree that no structural steel building has ever collapsed due to fire.  the jet fuel burning would only reach temperatures of 1000 to 1200 degrees Fareinheit.  Steel does not melt until 3000 degrees Fareinheit.   Thermite or the hotter Thermate can reach temperatures of 4500 degrees instantly and is a very restricted explosive used by selected contractors to do demolitions.  Building 7 is a football field away from the twin towers and was not hit by a plane and suffered little damage from the collapse of the twin towers.  At about 5:30pm that evening building 7, which is a 45 story structural steel building collapsed in its footprint within 7 seconds.  The physicist talking said it fell at the speed of gravity.    An example of the speed of gravity in atmosphere would be like someone standing at the top of building 7 dripped a rock down to the street below.  The speed of gravity is an acceloration in conjunction with speed.  The speed of gravity is 32  feet persecond and increasing 32 feet per second for each second.  All three buildings came down at the speed of gravity.  the twin towers came down in 10 seconds each and building 7 came down in 7 seconds.  The 47 steel colums were cut into 30 foot lengths making it easy for truchs to hall them away to waiting ships for export to asia.  A company called SecureComm was in charge of security for the trade center buildings.  The director of security for SecureComm at the time was Marvin Bush, the presidents brother.   Thermate burns hotter and faster than thermite and has a sulfer additive which is lacking in thermite.  Sulfer  dioxide was found throughout the site of demolition.  No one can explain this.  Sulfer dioxide is a biproduct of Thermate after burning steel.  the other is Iron. Molton Iron was seen pouring out of sections of the buildings due to melting of the structural steel supports.  It is easy to identify in the film.  If you are not interested in the preliminary footage of the disaster, skip about a third in to hear the scientists testify in their own setting.
