>Is the film implying that the US gov't put all those people on planes and crash them into WTC and the pentagon? If not what happen to them?

Any explanation can be concocted. Witness protection program, if the actual planes were switched for drones? Who knows.

My take is that a more probable explanation would be that they just let it happen, and used it.
