Flight 93 hijacker: 'Shall we finish it off?'

The passengers continued with their assault, trying to break through the cockpit door. At 10:02 a.m. and 23 seconds, a hijacker said, "Pull it down! Pull it down!"

"The hijackers remained at the controls but must have judged that the passengers were only seconds from overcoming them," the report concludes.

"The airplane headed down; the control wheel was turned hard to the right. The airplane rolled onto its back, and one of the hijackers began shouting, 'Allah is the greatest. Allah is the greatest.'

"With the sounds of the passenger counter-attack continuing, the aircraft plowed into an empty field in Shanksville, Pennsylvania, at 580 miles per hour, about 20 minutes' flying time from Washington, D.C." (CNN)
