Osama bin Laden was planning to attack America on the 10th anniversary 9/11, according to documents seized by the U.S. Navy SEAL team when they killed the al Qaeda leader during a raid last May.
Investigators discovered a hit list among the information they found in bin Laden's compound. The documents show the 10th anniversary plot was still in the discussion stage.
U.S. officials say bin Laden and his operations chief talked about who would make up the attack team -- militants who had legitimate passports and other travel documents.
Threats are Serious
CBN News Terrorism Analyst Erick Stakelbeck said it's very likely al-Qaeda will still try to carry out these plots even though bin laden is dead.
"Every year the anniversary of that horrible date rolls around and we hear about al Qaeda possibly carrying out a symbolic plot and look, they are very big on symbolism," Stakelbeck explained.
"(It) doesn't get much bigger than doing it on the anniversary of the biggest terrorist plot in American history, number one," he said.
"And number two, targeting the president and targeting the man Petraeus, David Petraeus who really defeated al Qaeda in Iraq - big symbolic targets for al Qaeda," he said.

Officials also revealed to ABC News that bin Laden wanted to try to fly a small plane into a sporting event to cause mass casualties.
As far as the discovery of a hit list, officials said that bin Laden's primary target was President Obama.
His plan was to kill the president by shooting down Air Force One or Marine One, more than likely during an overseas trip.
Bin Laden also hoped to kill Gen. David Petraeus, then commander of U.S. forces in Afghanistan the same way, either in a helicopter or fixed wing airplane with a missile or rocket-propelled grenade.
Investigators are also learning more about the travels of bin Laden's couriers, from the thumb drives taken from his compound.
Michael J. Morell, the acting director of the CIA, told his staff that one of their top priorities would be to make sure that neither that plan nor any others were carried out.
