There is a Vanity Fair article that is getting a lot of attention right now, about the response of the North American Aerospace Defence Command (NORAD) to the September 11th hijackings. To me, it seems well worth reading, especially for the primary source material that is included. While it is obviously a particular selection of the available evidence, it does demonstrate convincingly that this was not a scenario for which a plan existed, or during which an accurate appraisal of the situation was forthcoming.
I still mean to go see United 93, if it is still playing in Oxford. Would anyone else be interested in going?
