Commission staff members detailed the events of the morning of September 11, 2001 in which terrorists hijacked four airplanes in a coordinated attack on the U.S. and the minute-to-minute response by government and local officials. Following their report, a panel of military officials responded to the report and commission questions about the military response to the attacks. A third panel of aviation officials talked about the Federal Aviation Administration’s response to the events, including flight path charts of the four airplanes. Among the issues addressed were failures in communication between agencies, training for catastrophic events, and changes made since the attacks.
