Well my point was that in the video, the concrete compressed into a concave dent. At the Pentagon, whatever hit it made a hole through the concrete. I'm not disputing the missile theory at all, just observing the two different results in the concrete.

One possible variable is the age of the concrete... the Pentagon has stood since 1941 (oddly enough, the work began on Sept. 11, 1941...how's THAT for a coincidence?) and had many decades to harden and "set." The concrete barrier in the video above, well we don't know how old that barrier was... weeks? months?

It takes a long time for concrete to fully harden. So two flying objects hitting concrete at speed...one makes a dent, and one makes a hole. That is ALL I am pointing out, nothing more, nothing less. Don't read into my post more than I wrote.
