Reports of Controlled Demolition, Molten Steel, Thermite, etc.

Richard Gages' pseudoscientific deluge of misinformation is typical of the absurd ideas put forward by the 9/11 ‘truth’ movement. Real scientists rarely speak of the truth until they have spent enough time and experimental effort examining the evidence. Its amazing to me how the 'controlled demolition' people most of whom have little or no knowledge or experience or expertise in the building collapse or fire protection area, just dismiss the reports of the top engineering experts in their fields and take some theological professor’s absurd babble as gospel. The vaguest possibility is immediately touted as the truth and repeatedly echoed on the internet without any research or fact checking.

The recent BBC video utilized the top experts in the field. Shyam Sunder the NIST lead investigator, Gene Corley the American Society of Civil Engineers lead investigator both of whom have years and years if engineering experience. Gene Corley who was also the lead investigator in the Oklahoma City disaster, - which was destroyed by explosives, - said there was “no evidence of explosives” at the WTC site. He and Johanthan Barnett another experienced Fire Protection Engineer were on the scene immediately and examining the steel. Dr. Barnett described the devastation caused by the interior collapse of Building 5 from fire. These are all top experts in their fields and have to get things right in order to maintain their positions. I doubt a person inexperienced in the fire protection field could prove them wrong on anything related to the towers collapse without years of study, but they keep trying. The BBC put on the top building demolition expert Mark Loizeaux who explains how the towers collapse could not have been a controlled demolition and all he gets is blasted for being ‘in-on’ the conspiracy.

Four years after the 9/11 attack and without inspecting any of the steel the Architect Richard Gage is listening to some equally uninformed Philosophy Professor David Ray Griffin and has an epiphany and from then on he ‘knew’ that the buildings “had to be brought down by explosives”. “That’s the only way that you could have all the exterior columns in Building 7 fail within a fraction of a second.” How does he know all the columns failed at the same moment?

These lower columns were out of sight of the cameras. The first thing to fail was the east side interior columns as evidenced by the east penthouse on the roof caving in. Five seconds later the west penthouse caved in indicating core column failure and than the exterior frame started to descend, but there were large belt trusses around the entire building between the 22nd to 24th floors. There could have been columns failing at different times below these belt trusses but these trusses held the upper building steady until a large number of lower columns had failed. Building 7 took over 13 seconds to collapse not 6.

Many people interpreted the loud sounds and debris being projected out sideways during the Tower collapses as an indication that explosives were used to demolish the buildings. Most of these 'explosive' sounds, heard during the collapses were heard after the collapses began. In order for an explosion to cause a collapse it would have to occur before the collapse. Some thunder sounds were heard before the columns buckled and these were probably from floors collapsing.

The undamaged exterior walls can be seen bending and buckling inward in the videos of both Towers long before any sounds or ground vibrations occurred. In Tower 2, the exterior columns in the east wall were photographed bowing inward up to 10 inches, 18 minutes after the plane's impact. That's 38 minutes before the global collapse began. To be technical, you could say that Tower 2's collapse began slowly, with possibly some noise or impact sounds from falling floors, about 38 minutes earlier than the official collapse time. The explosive sounds and expanding dust clouds occurred just after the east wall buckled inward and started the collapse, and not before the buckling, as would have had to have happened with controlled demolition.

When the undamaged south wall of Tower 1 was photographed it was bowing inward up to 55 inches on floors 95 to 101, about six minutes before these columns were seen buckling inward. This bowing was witnessed and video taped by the Police Aviation Unit. In the North Tower "thunder" sounds were heard when some floors apparently collapsed on the south side 12 to 14 seconds before the top of the building was seen to tilt southward and begin falling as a unit starting the global collapse. Since each section of floor on the long-span side weighed about 500 tons, I would explore these 'explosive' sounds in Tower 1 as evidence of a floor or floors detaching and impacting the floors below on the south side which most probably accelerated south wall failure. I believe practically all the supposed 'explosive' sounds can be explained by the impacts made by the collapsing buildings after the columns were pulled in and buckled by the bowing and sagging floors and when the floors themselves began impacting the floors below. The boom, boom, boom, boom, boom repetitive 'explosive' sounds reported by firefighters running as Tower 2 was coming down were most likely caused by the sequential collision of impacting floors after the top of the building began falling. The great quantity of air on each floor being compressed in a fraction of a second by great weight and momentum would propel air, smoke, and any concrete dust and debris outward from the building at great velocity by the bellows effect of the floors coming together so quickly.

This hypothesis doesn't explain melted steel.

Specifically, an expert stated about World Trade Center building 7:

George Washington's Blog

"A combination of an uncontrolled fire and the structural damage might have been able to bring the building down, some engineers said. But that would not explain steel members in the debris pile that appear to have been PARTLY EVAPORATED in extraordinarily high temperatures" .

Note that evaporation means conversion from a liquid to a gas; so the steel beams in building 7 were subjected to temperatures high enough to melt and evaporate them.
