<\/em>Introduction<\/strong><\/p>\n

The purpose of this short article is to document for the record an analysis of the final chapter in the UA 93 story.\u00a0 In the language of chaos theory, UA 93 became disruptive feedback once Cleveland Center entered a new flight plan for the hijacked plane in the air traffic control system, with destination Reagan National Airport.\u00a0 The disruptive feedback that United 93 was still in the air confounded the national level at the time and in the accounting in the aftermath.<\/strong><\/p>\n

UA 93 lost on TSD at 1028 EDT<\/strong><\/p>\n

Here is a clip from the F2 Position, National TRACON (1 DCA 101-102 Tape 1-2 F2 1327-1450 UTC, as archived by NARA as part of the Commission files)\u00a0 The F2 Position controlled the Andrews fighters once airborne.\u00a0 As of 1028 the F2 Position knew that there was no target associated with UA 93. 1028 UA 93 not in system<\/a><\/strong> <\/strong><\/p>\n

In previous articles I have dealt with disruptive feedback, primarily in terms of the false report of AA 11 still airborne and the erroneous report that Delta 1989 had been hijacked.\u00a0 In the language of chaos theory feedback is disruptive if it results in “a gain” to a system.\u00a0 Concerning events of 9-11 that “gain” was the addition of planes the either had ceased to exist or were not in distress.\u00a0 By that measure, the introduction of a new flight plan for UA 93 by Cleveland Center became disruptive.\u00a0 That action by Cleveland Center was beneficial to air traffic control, specifically Cleveland and Washington Centers.\u00a0 It was not beneficial to the system at large as we shall see.<\/p>\n

Here is a link to analysis done by Brian Stark (Boone870 on the web) some months ago.\u00a0 That analysis included the audio clip from National TRACON.\u00a0 Stark’s analysis remains the definitive work on the UA 93 Traffic Situation Display (TSD) story, as told in the primary source and secondary information material of the day, supplemented by later recall by Transportation Secretary, Norman Mineta.\u00a0 <\/strong><\/p>\n
