Creative Speculation

...the plane passes up on hitting the white house, then passes up on hitting the capitol, than passes up on hitting the SecDef office to go around and hit the only newly blast-hardened wing that was relatively empty? You're joking right? You can't ask anyone to believe that someone would pass on those targets.

I see two alternatives - either someone knew the wing was relatively empty and steered there to reduce casualties & deliver more of a symbolic hit or the ONI was targeted. But why ONI? Why not hit that sprawling CIA complex at Langley that's only a minute or two away by air if you want to kill spies? ONI was Jonathan Pollard's old haunt - that give us some idea of the level of material and activity they're involved in - far above and beyond what some terrorist might be after.

So back to Nr. 1 - Don't gloss over the main point - do you believe the terrorists just happened to pick the same day as the exercises-that that was just a coincidence?
