I swear, if we didn't have extensive news footage of the WTC impacts, we would have the same people stating that no plane ever hit the Twin Towers. Cheney and Rumsfeld probably planted the demolition charges personally.
I hate to break it to you but there are idiots out there saying almost the same thing. Morons are claiming left and right that there were explosive charges planted in the WTC to drop them and that the Gov't set it up or at the least knew about it.
These people are idiots. Unfortunately say something loud enough and often enough and people start to believe it.
