9:28 a.m. September 11, 2001: Myers Updates Clarke Videoconference on Fighter Response
According to his own account, during a video conference with top officials that he is directing, counterterrorism “tsar” Richard Clarke asks Joint Chiefs of Staff Vice Chairman Richard Myers, “I assume NORAD has scrambled fighters and AWACS. How many? Where?” Myers, who is at the Pentagon, replies, “Not a pretty picture, Dick. We are in the middle of Vigilant Warrior, a NORAD exercise, but… Otis has launched two birds toward New York. Langley is trying to get two up now [toward Washington]. The AWACS are at Tinker and not on alert.” Vigilant Warrior may be a mistaken reference to either the on-going war game Vigilant Guardian, or perhaps another exercise called Amalgam Warrior (see 9:28 a.m. September 11, 2001). Otis Air National Guard Base is in Massachusetts, 188 miles east of New York City; Langley is in Virginia, 129 miles south of Washington; Tinker Air Force Base is in Oklahoma. Clarke asks, “Okay, how long to CAP [combat air patrol] over DC?” Myers replies, “Fast as we can. Fifteen minutes?” [Clarke, 2004, pp. 5] The first fighters don’t reach Washington until perhaps more than 30 minutes later (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001). However, this account—or at least the time Clarke alleges the conversation occurs—is contradicted by Myers himself and Senator Max Cleland (D). Myers claims he has been at a meeting on Capitol Hill with Cleland since about 9 o’clock, and does not arrive back at the Pentagon until after it is hit, which is at 9:37 a.m. [American Forces Press Service, 10/23/2001; MSNBC, 9/11/2002; CNN, 4/15/2003; American Forces Press Service, 9/8/2006] Cleland confirms the existence of this meeting, and claims that Myers is with him until around the time of the Pentagon attack. [CNN, 11/20/2001; Atlanta Journal-Constitution, 6/16/2003] (There are, though, some inconsistencies in Myers and Cleland’s accounts of this period (see (Shortly After 9:03 a.m.) September 11, 2001).

Richard Clarke: "I assume NORAD has scrambled fighters and AWACS. How many? Where?"

Richard Myers: "Not a pretty picture, Dick. We are in the middle of Vigilant Warrior, a NORAD exercise, but… Otis has launched two birds toward New York. Langley is trying to get two up now [toward Washington]. The AWACS are at Tinker and not on alert."

Isn't that statement an indication that Vigilant Warrior somehow hindered the air response?

From the 9/11 report:

116. On 9/11, NORAD was scheduled to conduct a military exercise, Vigilant Guardian, which postulated a bomber attack from the former Soviet Union.We investigated whether military preparations for the large-scale exercise compromised the military’s response to the real-world terrorist attack on 9/11. According to General Eberhart, “it took about 30 seconds” to make the adjustment to the real-world situation. Ralph Eberhart testimony, June 17, 2004.We found that the response was, if anything, expedited by the increased number of staff at the sectors and at NORAD because of the scheduled exercise. See Robert Marr interview (Jan. 23, 2004).

Not Vigilant Warrior, but Vigilant Guardian. That's something that should be cleared up I think. Also, I never understood what Eberhart meant. Allegedly, none of the planes were intercepted on 9/11, however, according to Eberhart, the wargames "expedited" the response. How could you tell?

As HC mentioned, he may have been referring to Amalgam Warrior.

9:28 a.m. September 11, 2001: NORAD Possibly Holding ‘Live-Fly’ Training Exercise
According to former counterterrorism “tsar” Richard Clarke, around this time the acting Chairman of the Joint Chiefs of Staff Richard Myers speaks to him via video link (see 9:28 a.m. September 11, 2001). During their conversation, Myers mentions, “We are in the middle of Vigilant Warrior, a NORAD exercise.” [Clarke, 2004, pp. 5] However, no other references have been found to this exercise, “Vigilant Warrior.” Considering that exercise terms are “normally an unclassified nickname,” [Chairman of the Joint Chiefs of Staff, 4/23/1998 pdf file] this is perhaps a little odd. Could Richard Clarke have mistakenly been referring to the Vigilant Guardian exercise (see (6:30 a.m.) September 11, 2001), which is taking place on 9/11? According to a later news report though, NORAD confirms that “it was running two mock drills on Sept. 11 at various radar sites and Command Centers in the United States and Canada,” one of these being Vigilant Guardian. [New Jersey Star-Ledger, 12/5/2003] If this is correct then there must be another NORAD exercise on 9/11. If not “Vigilant Warrior,” a possibility is that the exercise referred to by Richard Clarke is in fact “Amalgam Warrior,” which is a NORAD-sponsored, large-scale, live-fly air defense and air intercept field training exercise. Amalgam Warrior usually involves two or more NORAD regions and is held twice yearly, in the spring for the West Coast and in the autumn for the East Coast. [US Congress, n.d.; Airman, 1996; Arkin, 2005, pp. 254; GlobalSecurity (.org), 4/27/2005] Is it possible that in 2001 the East Coast Amalgam Warrior is being held earlier than usual (like Global Guardian (see 8:30 a.m. September 11, 2001)) and is taking place on 9/11? In support of this possibility is a 1997 Defense Department report that describes the Stratcom exercise Global Guardian, saying it “links with other exercise activities sponsored by the Chairman, Joint Chiefs of Staff, and the Unified Commands.” The exercises it links with are Crown Vigilance (an Air Combat Command exercise), Apollo Guardian (a US Space Command exercise), and—significantly—the NORAD exercises Vigilant Guardian and Amalgam Warrior. [US Department of Defense, 5/1997; GlobalSecurity (.org), 10/10/2002] Since in 2001, Vigilant Guardian (see (6:30 a.m.) September 11, 2001) is occurring the same time as Global Guardian, might Amalgam Warrior be as well? In his book Code Names, William Arkin says that Amalgam Warrior is “sometimes combined with Global Guardian.” [Arkin, 2005, pp. 254] Amalgam Warrior tests such activities as tracking, surveillance, air interception, employing rules of engagement, attack assessment, electronic warfare, and counter-cruise-missile operations. A previous Amalgam Warrior in 1996 involved such situations as tracking unknown aircraft that had incorrectly filed their flight plans or wandered off course, in-flight emergencies, terrorist aircraft attacks, and large-scale bomber strike missions. Amalgam Warrior 98-1 was NORAD’s largest ever exercise and involved six B-1B bombers being deployed to Eielson Air Force Base, Alaska, to act as an enemy threat by infiltrating the aerial borders of North America. [Airman, 1996; Arkin, 2005, pp. 254; GlobalSecurity (.org), 4/27/2005] Another Amalgam Warrior in fall 2000 similarly involved four B-1 bombers acting as enemy forces trying to invade Alaska, with NORAD going from tracking the unknown aircraft to sending up “alert” F-15s in response. [Eielson News Service, 10/27/2000; Associated Press, 10/29/2000] If either one (or both) of these exercises ending with the name “Warrior” is taking place on 9/11, this could be very significant, because the word “Warrior” indicates that the exercise is a Joint Chiefs of Staff-approved, Commander in Chief, NORAD-sponsored field training exercise. [North American Aerospace Defense Command, 8/25/1989] Real planes would be pretending to be threats to the US and real fighters would be deployed to defend against them.

Something that definitely needs to be cleared up.

May 8, 2001: Cheney to Oversee National Effort for Responding to Domestic Attacks, But No Action Is Taken Before 9/11
President Bush entrusts Vice President Cheney to “oversee the development of a coordinated national effort,” to address the threat posed to the United States by chemical, biological, and nuclear weapons. Bush states that he has also asked Joe Allbaugh, the director of the Federal Emergency Management Agency (FEMA), to create an Office of National Preparedness. This office is supposed to implement “the results of those parts of the national effort overseen by Vice President Cheney that deal with consequence management,” and it “will work closely with state and local governments to ensure their planning, training, and equipment needs are addressed.” Bush says he “will periodically chair a meeting of the National Security Council to review these efforts.” Cheney informs CNN, “[O]ne of our biggest threats as a nation” could be “domestic terrorism, but it may also be a terrorist organization overseas or even another state using weapons of mass destruction against the US.… [W]e need to look at this whole area, oftentimes referred to as homeland defense.” He makes no mention of either bin Laden or al-Qaeda. [CNN, 5/8/2001; White House, 5/8/2001; New York Times, 7/8/2002] Cheney is meant to head a group that will draft a national terrorism response plan by October 1. [Chicago Sun-Times, 5/5/2001; Insight on the News, 6/18/2001] But, as Barton Gellman later comments in the Washington Post, “Neither Cheney’s review nor Bush’s took place.” [Washington Post, 1/20/2002] Former Senator Gary Hart (D) later implies that the president assigned this specific role to Cheney in order to prevent Congress from enacting counterterrorism legislation proposed by a bipartisan commission he had co-chaired in January (see January 31, 2001). [Salon, 4/2/2004; Salon, 4/6/2004] In July, two senators will send draft counterterrorism legislation to Cheney’s office, but a day before 9/11, they are told it might be another six months before he gets to it (see September 10, 2001). [Newsweek, 5/27/2002] Cheney’s “National Preparedness Review” is just beginning to hire staff a few days before 9/11 (see September 10, 2001). [Congressional Quarterly, 4/15/2004]

...Mineta's testimony. Isn't "the plane is 30 miles out, the plane is 10 miles out do the orders still stand? Of course they still stand have you heard anything to the contrary" pretty damning evidence that Cheney was in charge of the Air Force that morning? And if he was in charge of the Air Force it isn't a stretch to imagine him in control of wargames involving the Air Force. Though I see your point Jon it is almost impossible to prove conclusively. Yet another reason we need a new investigation ASAP.

The war games were not planned for 9/10 or for 9/12 or for any other day. They were planned for 9/11!
