I just find it amazing that there were people who knew it was going to happen and nothing was done.
Despite the fact that many, many people saw a PLANE hit the Pentagon, you want to ignore all the eye witnesses, because you THINK you know how the crash site should have looked. If you could produce ONE eye witness who said he/she saw something other than a plane hit the Pentagon, no doubt you would be screaming for all of us to listen to an eye witness. You can't, so you simply ignore what the eye witnesses did see, since it doesn't fit your "theory".
The funny and sad part is that you think you "in the know", while the rest of us are naive sheeple being led around. YOU are the one being led around. YOU are the one who chooses to entertain absurd conspiracy theories and let complete morons fill your head with patently crazy, idiotic ideas. MOST of us have the common sense to see right through such incoherency. YOU are devoid of even that level of logical thinking. Obviously this is not the first time for you to pollute your mind with fantastical theories disguised as "the truth". You are well on your way to being completely unable to distinguish fact from fiction, fantasy from reality. Congratulations.
