Security scare aboard Airline flight

DENVER, Colo. -- The 10th anniversary of the 9/11 attacks put all U.S. airports on high alert this weekend and that made for several scary situations.

F-16 fighter jets shadowed a Frontier Airlines flight from Denver into Detroit. This, after two passengers made several crew members suspicious.

One man reportedly spent 20 minutes in the bathroom, in the back of the plane, while another waited in a gallery before using the bathroom for another 20 minutes.

Both men and a third person, were taken into custody, but the FBI says no arrests were made.
