embedded in the American Express building about 120 meters (circa of 120 yards) away.Piece of the WTC embedded inthe Amex buildingSome "experts" were on television sayingthat these pieces of the WTC were ejected laterally due to air that was beingmoving in the core of the building that was essentially hollow and was beingcompressed as the top came crushing the bottom. But keep in mind that the airbeing compressed does not have a prefer direction to follow, the standard wouldbe to take the entire floor and then blow all the windows while leaving thebuilding. And as we can see in the picture below there were poofs of air farbelow the line of destruction.Poofs of air in the WTCNo other building around the towers, other theWTC 7 which was more distant, as can be seen in the schematic of the WTCcomplex, collapsed due to fire and damage caused by debris from the towers.WTC complex schematicWTC 3, a 22-story building directly below thetowers was split in half by the debris but did not collapse.WTC 3WTC 4, a 9-storey building was almost completelydestroyed but the structure remained standing.WTC 4WTC 5 had 9-story, suffered from a severe fireand damage caused by debris but did not collapse.WTC 5WTC 6, 8 floors, suffered massive damages dueto wrecks and fires but did not fall. WTC 6We must also remember that several people,including Brian Clark, manager of the firm Eurobrokers, managed to leave thetop of the towers. They were above the impact point, and managed to get to the lobbysaving themselves. If the fire was hot enough to weaken steel, at least 900 C,how these people manage to do this?Contrary to what happened with the twin towers,causing considerable damage to adjacent structures, WTC 7 collapsed symmetricaldirectly into its on footprint with a total disintegration of the steel structureand limited damage to adjacent structures as seen in the photos below.WTC 7 after the collapseWTC complex after the collapsesFirefighters and several witnesses reported aseries of explosions before and during the collapse of the towers as seen inthe video "Fireman Explosion Testimony" on YouTube (http://www.youtube.com/watch?v=IO1ps1mzU8o).And in this other video (http://www.youtube.com/watch?v=CcRs1fv8i3I)called "Explosions on 911 " several firefighters have been together ina pay phone calling home telling their families that they are ok. Suddenly theyare startled by a loud sound of an explosion. This is one of the explosions inWTC 7 that occurred long before its collapse.As the buildings were collapsing they created apyroclastic cloud of pulverize concrete that is much more common to be seen involcanic eruptions than in collapsing buildings. Pyroclastic cloudEvidence of the incendiary Thermite was found insteel samples collected. This material which is a combination of aluminum withiron oxide reaches temperatures of 2400 C in 2 seconds and is commonly used incontrolled demolitions for cutting structural steel columns. In this video"9/11 Experiments: The Great Debate Thermate" by Jonathan Cole (http://www.youtube.com/watch?v=5d5iIoCiI8g) we see an experiment where the thermite is used to cuta steel beam. Once that the two materials begin to react, the energy releasedis so great that melts steel. Metal pieces of WTC. Theyare evidence of molten steel and severe erosion by
