F4 vs Concrete--guess which wins?

I have finally found the video I had been seeking for so long.  As the narrative with this video points out, so many of the conspiracy theorists about 9-11-01 point out that there was very little aircraft wreckage after the airliner hit the Pentagon.  Well, those of us that have, for years, seen these types of videos expected as much.

Aircraft tend to disintegrate when they come in contact with highly reinforced concrete.

Watch... and learn.
