Indications of the Imminent Collapse
of the World Trade Center Buildings
Disprove Explosives Theory
"The NYPD aviation unit reported critical information about the impending collapse of the buildings." They could see that the exterior steel beams of the buildings were bowing. You can see the inward bowing of the steel columns in pictures of both WTC 2, (the first building to collapse) and WTC 1 (the second building to collapse.)
Dr. Shyam Sunder, lead investigator for NIST's building and fire safety investigation into the WTC disaster, said, "While the buildings were able to withstand the initial impact of the aircraft, the resulting fires that spread through the towers weakened support columns and floors that had fireproofing dislodged by the impacts. This eventually led to collapse as the perimeter columns were pulled inward by the sagging floors and buckled." "The reason the towers collapsed is because the fireproofing was dislodged," according to Sunder. If the fireproofing had remained in place, Sunder said, the fires would have burned out and moved on without weakening key elements to the point of structural collapse." - Latest Findings From NIST World Trade Center Investigation Released
"According to Shyam Sunder, the concave bowing of the steel was seen on the sides of the towersopposite where the planes hit them. At 10:06 a.m. that morning, an officer in a police helicopter reported that ``it's not going to take long before the north tower comes down.'' This was 20 minutes before it collapsed. In another radio transmission at 10:21 a.m., the officer said he saw buckling in the north tower's southern face, Shyam Sunder said."
"Engineers believe the bowing of the exterior steel beams near the flame-engulfed floors was the critical "triggering point" because that's the direction each tower tiltedas it came crashing down."
"The report includes photographs taken from police helicopters showing the bending columns."
Key findings include:
- Floor sagging and exposure to high temperatures caused the perimeter columns to bow inward and buckle—a process that spread across the faces of the buildings.
- Even though the jet fuel on the planes burned off in the first few minutes after impact, there was enough office furniture to sustain intense fires for at least an hour.
- The original builders of the twin towers and those who later renovated the structures did not have a clear technical standard for deciding on how much insulation to use around the structural beams, many of which gave way in the intense heat.
Just like they are not qualified or have the expertise to identify molten steel or explosions apparently...lol
Its hilarious watching you claim that these police, firemen and civilians do no have the expertise to identify molten steel or explosives, but then in the next breath, they have the expertise and knowledge to determine the warning signs a building is going to collapse.
The funniest part is that you do not see how pathetic your arguments are and how dumb you look everytime you hypocritically contradict yourself without realising what you are doing....lol
