That's good video and it does show exactly how the floors at the impact area collapsed first and the weight of upper floors came crashing down taking the rest of the building with them. It's very clear and obvious in the video.

<<< Initially only those couple of floors crushed, but the 20+ floors that were above them dropped with more energy than the lower floors had strength. It's pretty easy to see in the videos. >>>

The columns collapsed because some of the floors collapsed. The buildings sides had to remain vertical in order to keep their strength. You can do an experiment at home. Place a soda or beer can on the floor. Gently balance yourself on the can with one foot (may need to hold onto a wall for balance). The can will support your weight. Now with your other foot, gently tap against the side of the can until you make a slight dent. The can will crush under the very same weight.

Yes, excellent idea..........

Ok, I tried it. But how come the can didn't pulverize into a massive cloud of dust and tiny pieces of shrapnel? <g>
