About this episode

The episode discusses the impact of Sept. 11 on national security and intelligence agencies in the U.S.

It’s been 25 years since al-Qaida attacked the United States by hijacking airplanes and crashing them into the World Trade Center and the Pentagon, with a fourth plane crashing into a field in Pennsylvania. Sept. 11 represented a new kind of national security threat, and a new national security architecture was created to confront it. Before a live audience at NPR, host Mary Louise Kelly discussed how that day changed the country and its spy agencies , with people who worked on the frontlines of government and intelligence.
