there is nothing wrong with the video or what it shows. you must also remember these are low grade video shot at hundreds of feet away, minute detail does not exist.

Ummm..... the towers weren't hollow tubes:
The perimeter columns were steel (see here:

Each tower had 47 massive core columns.
Between each floor was a slab of steel-reinforced concrete. (The "plane" hit on an angle impacting approximately 7 floors)
Here's an analogy to help explain:
Let's say you're driving a car toward a brick wall. How fast would you need to drive for the car to glide smoothly in the wall without showing signs of bending, twisting, or tearing?
