Penta-Collapse

"Why does this shot pull in tight then cut away right before the roof comes down at the pentagon? Think maybe someone made sure it came down? Can't have a plane wreck without a wreck! So where's the huge boeing that crashed here?....must have vaporised as it destroyed this section of the pentagon. See look, the building is a mess...which proves a plane crashed into it! This is how a lot of people think, it's amazing."
