Before 9:36 a.m.: Officials Claim NORAD is Monitoring Flight 93

According to one account given by NEADS Commander Robert Marr, some time before around 9:36 when it changes direction, while it is still flying west, Flight 93 is being monitored by NEADS. Marr describes how, “We don’t have fighters that way and we think [Flight 93 is] headed toward Detroit or Chicago.” He says he contacts a base in the area “so they [can] head off 93 at the pass.” Not only does NORAD know about the flight, but also, according to NORAD Commander Larry Arnold, “We watched the 93 track as it meandered around the Ohio-Pennsylvania area and started to turn south toward DC.” (This change of direction occurs around 9:36 a.m.) [Filson, 2004] This account completely contradicts the 9/11 Commission’s later claim that NEADS is first notified about Flight 93 at 10:07 a.m. [9/11 Commission, 6/17/2004]

(9:36 a.m.-10:06 a.m.): Military Claims it is Tracking Flight 93 and Ready to Shoot it Down; 9/11 Commission Says Otherwise

Several senior officials claim that the US military is tracking Flight 93 as it heads east and is ready to shoot it down if necessary.
bullet Brigadier General Montague Winfield says that the Pentagon’s National Military Command Center (NMCC) has “received the report from the FAA that Flight 93 had turned off its transponder, had turned, and was now heading towards Washington, DC.” He adds, “The decision was made to try to go intercept Flight 93.” [ABC News, 9/11/2002]
bullet Major General Larry Arnold, the commander of the Continental United States NORAD Region, says, “I was personally anxious to see what 93 was going to do, and our intent was to intercept it.” Three fighters have taken off from Langley Air Force Base in Virginia (see 9:30 a.m. September 11, 2001). According to Arnold, “we launched the aircraft out of Langley to put them over top of Washington, DC, not in response to American Airline 77, but really to put them in position in case United 93 were to head that way.” [9/11 Commission, 5/23/2003] He says, “as we discussed it in the conference call, we decided not to move fighters toward 93 until it was closer because there could have been other aircraft coming in,” but adds, “I had every intention of shooting down United 93 if it continued to progress toward Washington, DC… whether we had authority or not.” [Filson, 2004, pp. 73]
bullet NEADS Commander Robert Marr is reportedly “focused on United Flight 93, headed straight toward Washington.” He concurs with Arnold, saying, “United Airlines Flight 93 would not have hit Washington, DC. He would have been engaged and shot down before he got there.” [Filson, 2004, pp. 73] Marr and Arnold both say they were tracking Flight 93 even earlier on, while it was still it was still heading west (see Before 9:36 a.m. September 11, 2001).
Yet, completely contradicting these claims, the 9/11 Commission will conclude that the military only learned about Flight 93 around the time it crashed. It says the NMCC learned of the hijacking at 10:03 a.m. (see 10:03 a.m. September 11, 2001). Based upon official records, including recordings of the NEADS operations floor, it says NEADS never followed Flight 93 on radar and was first alerted to it at 10:07 a.m. .
