Can someone explain something to me?

More and more these days, I get people telling me they believe in the controlled demolition theory. I ask why, and they say they saw a documentary. Then I ask them to explain how it was done, and I never seem to get a clear response.

So here's what I always offer.

When those planes hit, they did four things:

1. Started a big fire;

2. Caused the building to torque around, damaging the superstructure;

3. Knocked the insulation off the steel reinforcements underneath the floors above and below the impact;

4. Disrupted the sprinkler system.

Steel melts at about 1,400 degress. The fire within the buildings was reported to have reached somewhere around 2,000 degrees. No sprinkler system was working to decrease the heat. With the insulation knocked off the steel struts under the floors, they melted and collapsed inwards and down. Thus, the buildings folded up on themselves and collapsed straight down and in.

As for WTC7 - the building I am always handed as the irrefutable proof - I have seen pictures that show severe damage and fire before it collapsed. Also, there were two 30,000 gallon tanks of fuel under the basement, there to be used by emergency generators if the power got cut. Between the damage to WTC7 from the hits on the main WTC buildings, and the explosion of those two tanks (i.e. the suspicious explosions reported by firefighters), it is entirely concievable that the building would fall into its own footprint.

This all makes a hell of a lot more sense than the idea that nefarious shadow people wired a bunch of buildings to explode without anyone seeing them, hearing them, noticing anything amiss, and without this massive undertaking coming to light at some point. Remember, this is the admin that failed to keep relatively simple secrets like the Wilson leak and the NSA wiretapping. I don't think they have the brain wattage to keep something like this under wraps.

So, explain to me why I'm wrong.
