I came across a web page that explained some things in a way that may sound far-fetched to most, but it makes a lot of sense once you see some of the pictures shown.
“As seen in the following pictures, the cores of the towers were not distracted by thousands of powerful cutting charges but by a modern thermonuclear explosive, a small hydrogen bomb. In the picture below, a hydrogen bomb explosion, the bomb having been placed in the cellar and directed to the core, has reached the roof of the tower and the upper parts of the outer walls. On its way up the waves of fire pressure partially penetrated about 100 floors of concrete and steel. Over ten million degrees of heat caused by a hydrogen bomb sublimised all water within the concrete in a moment. Water exploded extremely quickly into 24-fold volume and totally pulverized the concrete. Even people and computers that were in the buildings disappeared turning into heat and light. That is why almost nothing of them was found in the ruins.
Burning radiation is absorbed in steel so quickly that steel heats up immediately over its melting point 1585 °C (approx. 2890 °F) and above its boiling point around 3000 C (approx. 5430 °F). In the pictures down below, super hot groups of steel pillars and columns, torn from wall by pressure wave, are sublimized. They immediately turn into a vaporized form, binding heat as quickly as possible. Bursts upwards, even visible in the picture below, are not possible for a gravitational collapse or for cutting charges which are used horizontally.”
Now be realistic: is this a normal collapse?
