All support on every floor?? Are you kidding?? What kept the building together while it fell? LOL...after the supports were compromised it fell straight down at free fall speed. What do you need to hold the building together for 6.5 seconds? It was together when it started...it didn't finish that way at the bottom, did it? You can't even hardly find two pieces of steel connected together in that rubble. Yes we saw some pieces of steel bent up. But if it was a progressive collapse, as hypothesized, every column in the buildings would have been turned to pretzels and they would have absorbed tremendous amounts of energy and time getting that way. Not if they were all stressed close to their limit. The first failure would immediately bring the rest past their limits. It would come down like a house of cards. First of all the building was virtually empty. The major component for loading are the live loads...there were almost none in the building. No wind either. So even if one column or even three were over stressed it would not precipitate a progressive failure of every column on the floor. The reserve capacity in the framing was tremendous. For a column to get over stressed it has to absorb the loading. That takes energy and time. Free fall time of collapse says the columns carried no loads. If they carried any load the fall would have been slower.
