9/11 Live: The NORAD Tapes

How did the U.S. Air Force respond on 9/11? Could it have shot down United 93, as conspiracy theorists claim? Obtaining 30 hours of never-before-released tapes from the control room of NORAD's Northeast head-quarters, the author reconstructs the chaotic military history of that day—and the Pentagon's apparent attempt to cover it up.
