I dont understand How 19 guys with boxcutters can take over 4 commerial airliners on 9/11/01?

Conspiracy theories abound Would you fight a buy wioth a boxcutter? Are you aware a boxcutter is a sharp knife, and it will open you up just as easily as a box? If a plane didn't hit the Pentagon, where did it go? Where did the people go? Oh, right, the tv show, "Lost". Why would anybody offer a lone janitor millions of dollars to keep quiet if they were willing to kill other people? Doesn't make sense to anybody but a conspiracy theorist. Have you ever watched any of the tv shows showing people blowing down buildings? Not a one of them duplicates the crashing of the towers. Demolition charges to bring down the towers would have to have been placed inside columns on many levels of the buildings. Bombs would not do, the columns would all have to have been weakened. It would have taken a crew months of drilling, and hundreds of miles of cord to do what the conspiracy theorists insist happened. I'm not out of room, but I am tired of this crap that seems to keep coming back, just like dog poop in the yard.
