The controlled demolition of a North Texas building Saturday provided a stark reminder that WTC Building 7 and the twin towers could not have been brought down by any other means than planned implosion.

Watch the video of the Landmark Tower implosion in downtown Fort Worth and compare it to the South Tower of the WTC.

We see the classic crimp and leaning effects of controlled demolition in both cases.

The foundation of the building is blown first to weaken the structure and the building's 30 floors are then quickly popped out one by one to ensure the building falls rapidly in its own footprint.

WTC workers who were inside the building before its collapse state that they were eyewitnesses to underground explosions that were totally separate from the plane impacts.

The building falls faster than the speed of gravity as was the case with the twin towers.

Reminiscent of 9/11, dust then quickly engulfs surrounding city blocks.

Adjacent buildings receive minor damage such as broken windows and yet we are to believe that falling debris caused WTC 7, a 600 foot building that occupied an entire city block, to collapse in the late afternoon of September 11.

The twin towers and Building 7 were the first and only steel buildings to collapse from supposed fire damage in history.

Firefighter dispatch tapes prove that there were no raging infernos inside the towers and the fires were nearly extinguished. Photos before the collapse show a few minor fires in Building 7.

The Windsor Building in Madrid burned for nearly 24 hours as raging fires enveloped almost all of its 32 floors. The steel framed building did not collapse. The South and North towers collapsed within 56 and 103 minutes of being hit by planes respectively.

What is wrong with this picture?
