After the columns bowed, the weight was no longer going straight down. Like taking a straw and bowing it in the middle, it no longer can hold the same weight as it did when it was straight. The building tried to transfer the load to the core columns and massive hat truss on the roof. The weakened core, weakened by fire and impact, couldn't hold the massive weight from tilting. As with the perimeter column, the massive load on the deformed core columns gave way.

From another website, I honestly don't understand what this means because I have no engineering knowledge or know the terms being used. But here it is.

Thirdly, I'd really like some sources for your claims...

The tilt/rotation is VERY easy to explain. The plane hit building closer to the sides so that side was weaker. When the columns began to fail, they were all failing at the corner. If you take the corner off of something it's going to twist.

Nice try though...

I would love for someone to explain using the laws of physics, how the top part of the building, after making the tilt maneuver, does not fall over onto the street.
