Yeah dont' give up Sum. Opening minds is benificial to the world. Just don't let those who refuse to believe anything other than what they've been told hold you back.
As for the WTC falling due to the planes, impossible. First of all, if it was the heat that caused the beems to melt and collapse, the towers would not have fallen strait down, in an absolute free falls. Pancaking would have involved an initial collapse, followed by several others as the buildings wait couldn't withstand it anymore. It would have happened in chunks at a time and would definitely not have fallen strait down. Plus, you have to consider the fact that another tower fell that day and a plane didn't even hit it. So, in our lifetime of high rise buildings, in all of history, only 3 towers have fallen due to fire... and they all happened that day.
Another reason why heat could not have caused the buildings to collapse is because when the plane hit, most of the heat excaped in a huge ball off fire OUTSIDE the building. Especially the second plane.
The towers had to have been brought down another way.
