Twin Star

The Federal Aviation Administration (FAA) holds a training exercise based on the scenario of an aircraft hijacking, which involves a real plane playing the part of the hijacked aircraft. The exercise will be described to the 9/11 Commission in 2004 by Major Paul Goddard, who is the chief of live exercises for the North American Aerospace Defense Command (NORAD) at the time of the 9/11 attacks. According to Goddard, the exercise, held in 1995, is called “Twin Star” and the FAA invites NORAD to participate in it, “since a real commercial airliner was to be shadowed by a fighter intercept.” Goddard will tell the 9/11 Commission his understanding is that the exercise involves the entire FAA system, and the National Military Command Center (NMCC) at the Pentagon also participates in it. [9/11 Commission, 3/4/2004] Colin Scoggins, the military operations specialist at the FAA’s Boston Center on 9/11, will describe what is apparently this exercise when he is interviewed by the 9/11 Commission in 2003. He will say he believes the exercise is “joint FAA/military” and is conducted “in 1995 or 1996.” According to Scoggins, the exercise involves “a military scramble to escort a hijacked aircraft,” but the fighter jets taking part are “unable to intercept” the mock hijacked plane. [9/11 Commission, 9/22/2003 ] Apparently describing the same exercise in a documentary film, Scoggins will say, “We had run a hijack test years before [9/11] and the fighters never got off on the appropriate heading, and it took them forever to catch up.” [Michael Bronner, 2006]
