I would have never suspected a Major or high ranking officer.

Same..
But theoretically, do you think this might be a terrorist attack? I wouldn't be completely surprised, al-Qaeda for example are known to be quite good at biding their time and planning things, people in the US who 'knew' the hijackers of the 9/11 aircraft generally said they never noticed anything off about'em..
And what kinda effect will it have on the US military if it is al-Qaeda, and they have actually been infiltrated by al-Qaeda 'sleeper' agents?
