'Credible threat' cancels flight to Houston
A Continental Airlines flight from Washington, D.C., to Houston was canceled today after the U.S. Department of Homeland Security advised the airline of a "credible threat" that terrorists might target the flight.... Special Agent Bob Doguim with the Houston office of the FBI also said the cancellation was not based on any specific or corroborated information that the airliner was part of some potential Super Bowl-related attack.
U.S. officials have been concerned for some time that al-Qaida wants to use chemical, biological or radiological weapons aboard an airplane.... However, the threat information that led to the canceled flights this weekend did not indicate a specific method to bring down a plane or spread an illness such as smallpox, said a U.S. official speaking on the condition of anonymity, the AP said.
