Its like the WMD... we know saddam had them because we saw he used them before.....

We saw 2 planes fly into the WTC buildings, but instead of flying a third one into the pentagon, they used a missile instead, and just used the third hijacked plane as a rouse, to throw us off their tracks, and then mysteriously ditched it in the ocean somewhere! Brilliant!

Then they used the fourth plane as a rouse to make us think they were also going to hit the white house, but they didnt want to ruin that building, like the pentagon, it was too valuable to ruin, so they faked a crash into Penn. and they even had people on the plane make phone calls to their loved ones saying how they were going to try to take over the plane, again another brilliant rouse thought up by Bush to make it seem even more realistic! Brilliant!
