ALEXANDRIA, Virginia (CNN) -- Al Qaeda conspirator Zacarias Moussaoui told a stunned courtroom Monday that he and would-be shoe bomber Richard Reid were supposed to hijack a fifth plane on September 11, 2001, and crash it into the White House.
In a day of startling revelations, an unrepentant Moussaoui also said for the first time that he knew about al Qaeda's plot to hijack planes and fly them into the twin towers of the World Trade Center.
Under cross-examination, Moussaoui said he rejoiced at seeing the smoldering rubble and hearing a recording of a doomed flight attendant begging for her life.
Moussaoui explained to jurors why he doesn't trust his defense team: "I consider every American my enemy."
Moussaoui's boldest revelations focused on the 9/11 plot, his role, and what he knew in advance of the terrorist attacks.
"I had knowledge that the two towers would be hit, but I did not have the details," Moussaoui told jurors.
Moussaoui said that while he didn't know the "precise date to the day" of the planned terrorist attacks, he knew they would come soon after his arrest in August 2001 in Minnesota. He said he made sure he had a radio in his jail cell.
When the first news reports on September 11 described a fire at the trade center, Moussaoui said, "I immediately understood."
