Was the WTC purposly built for Destruction?
All buildings are built to be destroyed. You see, when a building is designed it has a design life (normally 100-120 years) after which it will need to be demolished. Now in large cities like New York destroying a building is a tricky task so the method of collapse is built into the structure. The method of collapse is that the building’s own weight will cause it to fall to the ground. This weight is mobilised by removing or demolishing the main strucurual steel in the building. At 9/11 the high temperature fires weakened the steel and once the top collapsed it caused the rest of the building to collapse. The fire would have filled the main ventilation shaft with smoke and when it was collapsing the smoke would have been forced out all the vents, hence why it looks like small explosions coming out of the collapsing building. STOP TRYING TO SEE A CONSPIRACY IN EVERYTHING UNLESS YOU HAVE PROOF.
