I personally believe a plane hit the Penatagon. I just dont believe the towers came down on there own the way that has been explained. I have found nothing to disprove this besides heresay and counter conspiracies.
How about logic?
Why would they blow up a building when the ones next door have been hit by planes?
Crony 1: Listen, we know that two hijacked planes are going to hit the twin towers. And that another one is scheduled to be flown into the Pentagon. However, we need to do more as its obvious that this isn't enough to inspire panic.
Crony 2: I know, lets blow up one of those smaller buildings next door to the twin towers. That will be sure to get some publicity then.
Crony 1: Brilliant. However, aren't we running a risk of being discovered? Surely the risk v reward ratio is way out of whack.
Crony 2: Nobody will notice.
Crony 1: But we will need tons of explosives, operatives to plant them, engineers to plan (we need it to land in its own footprint okay - don't ask me why, its not important), transport etc. And the building is in one of the most populated places on earth.
Crony 2: Everyone will be paid off and we will do all the work at night.
Crony 1: For 6 months?
Crony 2: Yes, easy done.
Crony 1: And just one more thing What if the planes miss the twin towers or the hijacking fails? Won't it look a bit silly if we are forced to just blow up a building for no reason at all?
Crony 2: We'll just blame terrorists.
Crony 1: But logistically its not possiblt to blow up a building that size in one act. It need months and months of work.
Crony 2: You worry too much. We've got people on the inside in the media. It will be right.
Crony 1: Okay then. lets do it.
