On That Day

Trade Paperback

The Definitive Timeline of 9/11

Anyone who experienced the attacks on September 11 cannot forget the imagery: the smoking, falling towers, the Pentagon smoldering, the Shanksville crash site, the first responders.

But there is an invisible story hidden in the wreckage, one that required years of patient investigation and the piecing together of a sequence from many scattered sources. By establishing the most definitive timeline of how that day unfolded, William M. Arkin shows how the US government failed in the face of the unprecedented attack. It is a story of laughable airport security, vulnerable airspace, blind intelligence, poor communications, muddled orders, Pentagon chaos, and presidential isolation. Everything about the emergency procedures of the governments-from White House security to continuity of government to military alerts-went wrong.

On That Day is a stunning, nightmare journey through a government reeling in confusion while many civilians performed individual acts of heroism. It is a chilling expose of government negligence and overreach, and a constitution in crisis.
