MSNBC news story 9-11-07 Explosion at Pentagon??

I can't remember the exact time of the broadcast, but a reporter cut in to say there there had been an explosion at the Pentagon, and that construction workers were running from the scene. They were unsure exactly what it was, but they were going to try to get more info, but I never saw anything else. Did anyone else happen to catch this? It was only on for maybe 2-3 minutes. I have been unable to find any other reports of this happening. It was on sometime between 9-10 am central time.

Uh, I think that you were watching the re-broadcast of the NBC coverage from 9/11/01. I was watching some of it and the NBC guy at the Pentagon said the exact phrase that you included in the OP on that day six years ago.
