9/11: North Tower "collapse" (Sauret)

I doubt the US government did this, but they definitely provoked it! It was a reaction to all the injustices caused by the US in the Middle East. Unfortunately, it's always innocent civilians who pay the price.

it makes me cry to watch this. its one thing to hate a country, but for people to go out of their way to cause this...

The towers were designed to witstand almost any kind of disaster. But because the airliner that hit the tower was from Boston it had almost a full fuel tank and caused a very big explosion. Also the steel girders supporting the tower were melted away, the tower collapsed.

Hawkins97, no, whether or not full progressive collapse is possible, jet full fires can NOT melt steel. NEVER.

The absolute theoretical maximum for hydrocarbon fires is 1200 degrees centrigrade, well over 300 degrees below the melting point of steel. However, not even this theoretical maximum is ever achieved in practice, and certainly not in the World Trade Center. (See NIST report, no evidence for temperatures exceeding 600 degrees centigrade)

True, but fuel isn't hot enough to melt steel, even weaken it. Fuel is 1/2kerosene , a low tempurature burning fuel.

Look at 2.09 there is a small explosion on the right hand side of the building (a small white puff of smoke) just before the building starts to fall. When the building falls the so called massive fires that caused the collapse are ejected from the windows. Funny I only see fire from the inpact floor and a small flame from a few stories up. If the building did have a lage fires over alot of floors flames would have been ejected form every where. As fire follows air.

because the camera was mounted on a tripod and there were these big explosions to cut the core columns before the actual collapse...

omg 2:00 theres a man who jumps on the west side, just some meters down from the molten metal area.

You see him at about 0:21 and 0:22 also. The day this happened will be with me the rest of my life.

Its the underground thermonuclear explosion...
Its energy travel internally upward starting to melt the massive core columns which also cause the collapse together with strategic cutter charges timed to go along with the arrival of this energy wave. Look for a video 'Eyewitness Hoboken' to get more of an inside scoop of the 4rt generation thermonuclear device explanation as first proposed by a Finish military expert.
