My first thought after hearing that the airliner had hit the Pentagon was of Clancy's novel where an airliner hit another Gov't building under the worst circumstances. Since the news was still referencing Palentinian terrorists at the time, my second thought was that the Palestinian cause was just about to end in failure.
"Clancy's novel where an airliner hit another Gov't building "
That is in a Clancy novel, really? Was that deliberate in the novel too?
