9/11 Truth: Why is there no footage showing a plane hit the Pentagon?

Dick Cheney ordered the military to stand down.......The Government rounded up all those camera's within minutes as well as the video from the gas station across the street. After years they released 4 frames off of one camera......what a joke....innocent people don't act this way. No plane was ever seen on video....Gee...I wonder why?

They have probably classified most information no one films the pentagon (boring) there were thousands of people videoing the twin towers. , and how on earth were they supposed to know that they were coming for the pentagon, and planes believe it or not can go really really fast, it is hard to respond when the plan is coming in at 600MPH.
