but there were witnesses that claimed to see the bases of the towers exploding just before it collapsed...even it were due to the concrete... then why did the government people blame it on the steel? im sure they shud know better if that's the case...as for the pentagon... people have claimed it to be missiles too... 2 people claimed to have seen a white quiet plane swift by and flew off just before the explosions...

well its just my .02 but then again u cud be right...who knows... :)
