That is an interesting site. I took a look at this article.

911blimp.net

A major flaw of ommission was obvious here. The author does understand physics but failed to connect all of his own dots. He assumed that the lower floors would significantly slow the collapse of the tower. Why doesn't he talk about the kinetic energy of the floors falling about 10-12 feet between each floor? KE goes up as the square of the velocity so the first floor below the impact site would offer litle resistance to the force of all those floors falling 10 feet. The next floor would be overcome easier as there is now one more floor's mass and more velocity for all the mass. Each successive floor would have less of an effect than the one before. The bottom few floors would have offered virtually no resistance.

Almost anyone can hold up 50 pounds Try dropping a 50 pound weight from 10 feet over your shoulders and catching it. You'll break both your arms without significantly slowing it down. You also have an advantage the floors didn't, which is that your arms don't have to absorb the entire force instantaneously.

That's not to say he is "wrong". He simply paints a one sided story to suit his needs. Hoping to look at more articles. Fascinating stuff!
