The authorized hardcover, indexed edition of the national bestseller.

Nearly three thousand people died in the terrorist attacks of September 11, 2001. In Lower Manhattan, on a field in Pennsylvania, and along the banks of the Potomac, the United States suffered the single largest loss of life from an enemy attack on its soil.

In November 2002 the United States Congress and President George W. Bush established by law the National Commission on Terrorist Attacks Upon the United States, also known as the 9/11 Commission. This independent, bipartisan panel was directed to examine the facts and circumstances surrounding the September 11 attacks, identify lessons learned, and provide recommendations to safeguard against future acts of terrorism.

This volume is the authorized edition of the Commission's final report.
