In the weeks and months following 9/11 the world was slowly awoken to the possibility all was not as the Bush regime had spoken. Exclusive real pictures of that day have now come to light. (Thanks Lightshadow 4)
It is a simple and as clear minded as this: A gravitational collapse could not cause the effects seen in these exclusive real photos.
High explosives and lots of them were needed to do what is seen here, combine that with the 10 second freefall destruction and the only possible explanation is DEMOLITION.
Judge For yourselves – could Gravity turn thousands of tonnes of concrete to dust in an instant?
