My Dad was in the Pentagon that day. He walked home a piece of the way until someone he knew saw him and picked him up. I think he got out before the rest of the Pentagon folks got to their cars (have you ever seen how far it is from the parking lot to the building?). His problem was that he took the Metro and the Metro closed down after the attack. In an unforeseen emergency I'm not sure there is a great solution. By the time buses get deployed somewhere, the streets are already crowded with people who want to get the hell out.
If something happened here, I'm on my bike and gone.
