Thanks Tom
(Damn, hit return again. I ALWAYS do that)
My response would be a reiteration oof exactly what Tom metioned, that the heat does not need to melt the lteel, that even relatively low temps could cause maojr weakening. I won't repeat it here, you can read it below again if you want.
But, to the "A Mr. Val Romero, went on record stating that the collapse of the towers bore all the characteristics of a controlled-demolition."
If the terrorists are trying to cause as much death and havoc as possible, WHY would they plant explosives to cause the towers to fall sraight down in a neat, controlled demolition? One of the biggest things to be thankful for after this attack is that they DIDN'T topple to the side and take out another whole city block.
