Documents recovered from the Pakistan compound where Osama bin Laden was killed in May show al Qaeda was planning for the 10th anniversary of Sept. 11 later this year, possibly by trying to kill President Barack Obama by shooting down Air Force One.
Officials say the terror group was also targeting Gen. David Petraeus, launching a missile or grenade at his aircraft as well.
A U.S. official, who was not authorized to speak on the record, described the Bin Laden documents as "him in his brainstorming mode ... hey, I have an idea, what if we did this."
Another U.S. official said the documents showed bin Laden was interested in attacking the United States on the tenth anniversary of the 9/11 terrorist attacks. According to that official, bin Laden wrote about "identifying a team of operatives to attack the homeland." But the official said there was nothing specific and "it's unclear his discussions about those operatives were more than discussion."
The first official said overall, the documents indicate "these were ideas, not fully or even partially planned plots."
