I will explain it to you, Dr. T.A.M.
The
only video which showed the "plane" hit live was the helicopter shot in the upper left of "The Hole That Wasn't There" graphic. They overlayed a CGI plane on to real video using the WESCAM system (the same one that inserts 1st down stripes on football fields). They screwed up, and the nose of the plane came through the other side. We call this "Pinocchio's Nose". They quickly cut to black, but it was too late.
After that, the other videos which emerged had to show the same thing. So they had to paste Pinocchio's nose into those as well.
There is no way the nose of that aircraft could survive crashing though those columns, but if it somehow could, then there would be a hole.
This also caused an additional problem, they had to make the nose disappear in all those other videos, so they pasted fake flames on top of the real flames. StillDiggin calls this the "Venus Plane Trap". Check out
