Here's some video also that is much closer to the scene. Go ahead and forward about a 1:35 into the video.
What do you think of the Purdue University simulation?

The simulation merges a realistic-looking visualization of the airliner approaching the building with a technical, science-based animation of the plane crashing into the structure.
The model indicates the most critical effects were from the mass moving at high velocity.
"At that speed, the plane itself is like a sausage skin," Sozen said. "It doesn't have much strength and virtually crumbles on impact."
But the combined mass of everything inside the plane – particularly the large amount of fuel onboard – can be likened to a huge river crashing into the building.
"Because the structural skeleton of the Pentagon had a high level of toughness, it was able to absorb much of the kinetic energy from the impact," said Christoph M. Hoffmann, a professor in the Department of Computer Sciences and at Purdue's Computing Research Institute.
"Most of the computer-simulated crashes you see in movies or on TV are not realistic from the point of view of physics," said Voicu Popescu, an assistant professor of computer science. "They are designed to be spectacular rather than realistic. What hasn't been done much, or, to our knowledge hasn't been done at all, is to create a visualization that looks realistic in the sense that you would recognize the Pentagon and the plane and is, at the same time, true to physics."

Maybe you're watching too many Hollywood action movies and are expecting something more like that. Or maybe those Purdue students are in on the cover up as well
