Moussaoui jurors hear Sept. 11 tapes
ALEXANDRIA, Va. -- In the final minutes of doomed United Air Lines Flight 93, Sept. 11, 2001, hijackers try to shake off passengers clamoring for control of the plane over Pennsylvania. Amid groans and sounds of a struggle, a voice says, "I am injured." A hijacker asks, "Shall we finish it off?" Moments later, the plane hurtles out of control to the ground, according to a cockpit voice recording played for a jury Wednesday by federal prosecutors seeking the execution of Zacarias Moussaoui.
