WASHINGTON (CNN) -- President Bush's daily intelligence briefing in the weeks leading up to the September 11 terror attacks included a warning of the possibility that Osama bin Laden's al Qaeda network would attempt to hijack a U.S.-based airliner, senior administration officials said Wednesday.
But, the officials said, there was no speculation about the use of an airplane itself as a bomb or a weapon, and no specific, credible information about the possibility of a hijacking of any sort.
Hijackers took over the controls of four planes on September 11, 2001. Two of those planes plowed into New York's World Trade Center, another jetliner nose dived into the Pentagon and the fourth aircraft crashed into Pennsylvania woodlands after passengers tried in vain to overcome the terrorists. More than 3,000 people died in the terrorist attacks.
Only one person, Zacarias Moussaoui, has been charged in connection with the attacks. He was arrested after coming under suspicious while taking flying lessons in Minnesota.
