September 11 (9/11) Attacks
Slow and Confused Communication
Orville Wright Federal Building, Washington, D.C., U.S.
NORAD scrambled two F-15s from Otis Air National Guard Base in Massachusetts and they were airborne by 8:53 a.m. Because of slow and confused communication from FAA officials, NORAD had 9 minutes notice that Flight 11 had been hijacked, and no notice about any of the other flights before they crashed. (after the first collision (American Airlines Flight 11)).
