"Well, I had just been told by Andrew Card that America was under attack. And I was collecting my thoughts." - Bush, explaining why he sat there for 7 minutes
You were collecting your thoughts? In a classroom? What thoughts were you collecting, since you obviously knew no details about what had happened? You hadn't previously had any plan for how to respond to an attack?
Well, George, while you were "collecting your thoughts" another plane was heading toward the Pentagon, and would strike it 20 minutes later.
And you were OUT of it.
