There is some incogruity there. If one can use a clock and see, then one cannot come up with 9.5 seconds for either tower or 6.5 for WTC 7.

It is still collapsing and has about 40 floors or so to go. That would put the collapsed firmly at something over 12 seconds, in the neighborhood of 14-15 seconds. How would one use a clock and eyesight to see that as 9.5 seconds?

For 6 seconds, you cannot see what is happening, then you can see the reminder of the collapse. You get a total collapse time of right at 13 seconds. How would one use a clock and eyesight to see that as 6.5 seconds?

Galileo did fine. Perhaps he just had a better watch than most alternate conspiracy theorists have?

WTC 1 & 2 were brought down by a combination of fuel laden 767's crashing into them and the resulting fires. The evidence and facts allow anyone to arrive at that conclusion. There is no evidence and are no facts to support any of the alternate theories - they are based on false information, some times doctored evidence, misinterpretation of evidence, bad guesses, bad science, or just wishful thinking.
WTC 7 was brought down by the same thing that brought down 24 other buildings in the area around the WTC towers - the collapsing towers. How could anyone not grasp how 1 out of 25 buildings collapsed while at the same time readily understanding how the other 24 were damaged or destroyed by the collapsing towers?
The building was heavily damaged and had extensive fires. There is no evidence that allows one to arrive at any conclusion other than the damage and the fires causing the collapse.

It clearly doesn't. The buildings were not designed to handle the huge dynamic loads placed on the structure once the collapse initiate. There are no structural engineers that see anything suspicious or wrong about the way they collapse or the amount of time it took for them to collapse. Les Robertson was *surprised* (and thankful) that they stood as long as they did.
