“Not a pretty picture, Dick. We are in the middle of Vigilant Warrior, a NORAD exercise…”
- General Richard Myers on September 11, 2001 as quoted in Richard Clarke’s Against All Enemies

ANCHORAGE, Alaska — A groundbreaking training exercise ended late Tuesday after U.S. and Russian fighter jets crisscrossed the Pacific in pursuit of a chartered plane playing the role of a hijacked airliner.
The “hijacked” plane – actually a chartered executive-style Gulfstream – landed in Anchorage after flying across the Pacific and back, monitored all the way by fighters and aerial command posts from both sides.
On board were officers from Russia and from the North American Aerospace Defense Command, a U.S.-Canadian force that patrols the skies over North America.
The exercise was designed to test how well Russia and NORAD could coordinate their efforts in the event of a hijacking, especially during the critical handoff stage when the commandeered plane moves from one side’s airspace to the other.
The drill will make it harder for terrorists to pull off a hijacking against the U.S., Canada or Russia by building up the air travel system’s defenses, said Canadian Forces Col. Todd Balfe, the deputy commander of NORAD’s Alaska region and the senior NORAD observer aboard the Gulfstream.
“I think any time that we increase our cooperation and our coordination, we harden ourselves against further events,” Balfe said.

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 
] 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.

Military personnel responsible for defending U.S. airspace had false tracks displayed on their radar screens throughout the entire duration of the 9/11 attacks, as part of the simulation for a training exercise being conducted that day. Technicians at NORAD’s Northeast Air Defense Sector (NEADS) were still receiving the simulated radar information around the time the third attack, on the Pentagon, took place. Those at NORAD’s operations center in Cheyenne Mountain, Colorado, were still receiving it several minutes after United Airlines Flight 93 apparently crashed in rural Pennsylvania.
No one has investigated why false tracks continued being injected onto NORAD radar screens long after the U.S. military was alerted to the real-world crisis taking place that morning. And yet we surely need to know more about these simulated “inputs” and what effect they had on the military’s ability to respond to the 9/11 attacks.
NEADS TECHNICIANS TOLD TO TURN OFF ‘SIM SWITCHES’
The terrorist attacks on September 11, 2001 took place in airspace that was the responsibility of NEADS, based in Rome, New York. NEADS was therefore responsible for trying to coordinate the military’s response to the hijackings. And yet, in the middle of it all, at 9:30 a.m. that morning a member of staff on the NEADS operations floor complained about simulated material that was appearing on the NEADS radar screens. He said: “You know what, let’s get rid of this goddamn sim. Turn your sim switches off. Let’s get rid of that crap.” [1] Four minutes later, Technical Sergeant Jeffrey Richmond gave an instruction to the NEADS surveillance technicians, “All surveillance, turn off your sim switches.” (A “sim switch” presumably allows a technician to either display or turn off any simulated material on their radar screen.) [2]
This means that at least some of the radar scopes at NEADS were still displaying simulated information–presumably false tracks–57 minutes after an air traffic controller at the FAA’s Boston Center called there and announced: “We have a problem here. We have a hijacked aircraft headed towards New York.” Forty-eight minutes had passed since the first attack on the World Trade Center occurred, and 31 minutes since the second tower was hit and it became obvious that the U.S. was under attack. It was only three minutes after Richmond gave his instruction, at 9:37 a.m., that the Pentagon was struck in the third successful attack that morning. [3]
Why were NEADS radar scopes displaying simulated information for so long during the real-world crisis, when it appears the technicians could have removed that information at the flick of a switch? Surely any false tracks could have hindered the ability of NEADS personnel to effectively respond to the attacks, so should have been terminated at the first sign of an actual emergency.
And yet this inexplicable behavior was not an exception. A similar thing happened at NORAD’s Cheyenne Mountain Operations Center (CMOC) in Colorado, where it appears that false radar tracks were being displayed for even longer than at NEADS.
NORAD OPERATIONS CENTER ASKS FOR ‘EXERCISE INPUTS’ TO BE STOPPED
At 10:12 a.m., an officer at the NORAD operations center, “Captain Taylor,” called NEADS and spoke to Captain Brian Nagel, the chief of live exercises there. After introducing himself, Taylor said, “What we need you to do right now is to terminate all exercise inputs coming into Cheyenne Mountain.” Nagel gave Taylor an extension number and asked him to call it to get the exercise inputs stopped. Taylor replied, “I’ll do that.” [4] “Inputs,” according to an article in Vanity Fair, are simulated scenarios that are put into play by a simulations team during training exercises. [5]
Taylor was presumably referring specifically to false tracks that had been transmitted onto radar screens at the CMOC, where more than 50 members of the battle staff had been participating in the exercise conducted that morning. [6] Indeed, the Toronto Star reported, “Any simulated information, what’s known as an ‘inject’” was “purged from the screens” at the CMOC in response to the news of the real-world attacks. (However, the report indicated, apparently incorrectly, that the false tracks appearing on CMOC screens were terminated earlier on, at some time shortly before 9:03 a.m., when the second WTC tower was hit.) [7]
If simulated material was still being displayed on CMOC radar screens at 10:12 a.m., this would be astonishing. By that time, 95 minutes had passed since–according to the 9/11 Commission–the military was first alerted to the hijacking of American Airlines Flight 11, and more than an hour had passed since the second plane hit the WTC. Flight 93 had apparently crashed in a field in rural Pennsylvania minutes earlier, and so the 9/11 attacks were already over. [8]
Why did it take so long for someone at the CMOC to call NEADS and ask it to “terminate all exercise inputs coming into Cheyenne Mountain?” Surely any simulated information should have been stopped as soon as NORAD learned of the real-world crisis taking place that morning.
The operations center was certainly in a valuable position to assist in the response to the terrorist attacks, so the intrusion of false tracks on its radar screens would presumably have considerably impaired the emergency response capabilities of the military. Airman magazine described the CMOC as the “nerve center of NORAD,” and its troops as “the eyes and ears of North America … nothing escapes their unsleeping watch.” [9] According to the Toronto Star, “Whether it’s a simulation or a real-world event, the role of the center is to fuse every critical piece of information NORAD has into a concise and crystalline snapshot.” [10] NORAD has stated that the center collected data “from a worldwide system of satellites, radars, and other sensors, and processes that information on sophisticated computer systems to support critical NORAD and U.S. Space Command missions.”
The CMOC provided “warning of ballistic missile or air attacks against North America, assists the air sovereignty mission for the United States and Canada, and, if necessary, is the focal point for air defense operations to counter enemy bombers or cruise missiles.” The Battle Management Center there provided “command and control for the air surveillance and air defense network for North America.” In 1994, for example, it monitored over 700 “unknown” radar tracks that entered North American airspace. [11]
NORAD INJECTS SIMULATED RADAR INFORMATION DURING EXERCISES
Simulated information was being transmitted onto radar screens the morning of September 11 as part of an annual command post exercise called Vigilant Guardian. All of NORAD, including NEADS, was participating in this exercise, which has been described as a “simulated air war” and as “an air defense exercise simulating an attack on the United States.” [12]
An information page on Vigilant Guardian stated: “All of NEADS, operations personnel are to have their sim switches turned ‘on’ starting at 1400Z 6 Sept. 01 till endex [the end date of the exercise, which was originally going to be September 13].” The information page added, “A sim test track will be in place and forward told [i.e. transferred to a higher level of command] to both NORAD and CONR,” NORAD’s Continental United States Region. Presumably this was why the NORAD operations center needed to contact NEADS in order to get the “exercise inputs” terminated. [13]
A memo outlining special instructions for Vigilant Guardian participants described how their equipment needed to be set up to deal with the simulated material. It stated: “The exercise will be conducted sim over live on the air sovereignty string. The Q-93 must be placed in the mixed mode to allow the telling [i.e. the communicating of information between facilities] of sim tracks.” [14]
The Q-93 was an important piece of equipment used by NORAD, described as “a suite of computers and peripheral equipment configured to receive plot data from ground radar systems.” [15] It had “connectivity to numerous domestic radar sites, receives flight plans from the FAA, and has bi-directional communications with NORAD headquarters and a real-time link to AWACS [Airborne Warning and Control System planes].” It performed “real-time surveillance, identification, and weapons control missions.” [16]
According to Master Sergeant Joseph McCain, the NEADS mission crew commander technician, “Q-93 radar screens have the ability to run a multiple input wartime scenario.” [17] Indeed, in 1999, then-Deputy Secretary of Defense John Hamre revealed that NORAD could inject “mass attacks” onto its radar screens. [18] In December 1998, for example, it conducted an exercise called Vigilant Virgo, which reportedly “analyzed the Y2K preparedness of the entire ground radar array network. These systems were put through a series of scenarios involving tactical warning.” [19] During this exercise, NORAD “injected 30 plus, well over 30 missile events into [its] sensors.” This was “data that was injected as though it was being sensed for the first time by a radar site,” according to Hamre. Of the more than 30 different simulated scenarios, some were “mass attacks” while others involved just “single missiles.” [20]
WHEN WAS VIGILANT GUARDIAN TERMINATED?
Since NEADS and the NORAD operations center were still receiving simulated radar information long after the 9/11 attacks began, this raises the question of when exactly Vigilant Guardian was brought to an end. According to some accounts, it was called off “shortly after” 9:03 a.m., when the second WTC tower was hit. [21] However, when at 9:15 a.m. a caller asked, “Did they suspend the exercise?” NEADS tracking technician Mark Jennings replied, “Not at this time, no.” Jennings continued, “I think they’re going to,” but added, “I don’t know.” [22]
In fact, one military newspaper has indicated that Vigilant Guardian may have been terminated more than half an hour after the attacks ended. According to the military information website, GlobalSecurity.org, Vigilant Guardian was held each year in conjunction with a U.S. Strategic Command (Stratcom) exercise called Global Guardian, and a 1997 Department of Defense report similarly listed Vigilant Guardian as one of several exercises that Global Guardian “links with.” [23]
An article in The Bombardier, the newspaper for Barksdale Air Force Base, Louisiana, stated that Stratcom ordered a pause in Global Guardian at 9:11 a.m. on September 11, but only “formally terminated” this exercise at 10:44 a.m. [24] Considering that false tracks were still being displayed on NORAD radar screens at 10:12 a.m., and that NORAD’s exercise that day was held in conjunction with Global Guardian, did Vigilant Guardian similarly continue until around 10:44 a.m. before being “formally terminated”?
CRITICAL QUESTIONS
The fact that key NEADS and NORAD operations center personnel had false information appearing on their radar screens throughout the 9/11 attacks raises critical questions that have yet to be investigated. We need to know who was responsible for transmitting the simulated “exercise inputs” to radar scopes. It has been reported that there was a “simulations team” working at NEADS the morning of September 11. [25] Was this team putting out the false tracks? If so, who were its members? Why did they continue with the simulation when it should have been obvious that a real-world crisis was taking place? And why didn’t their higher-ups order them to stop transmitting the false tracks?
We also need to find out how many radar scopes at NEADS, the CMOC, and other NORAD facilities across the U.S. were receiving the simulated information. And what scenarios were transmitted onto the screens? Considering that Vigilant Guardian has been described as a “simulated air war,” one would assume that many false tracks were being displayed.
Furthermore, we need to find out if personnel were able to distinguish genuine radar tracks from the simulated ones. It is worth noting that, since the mid-1990s, a tool called the PAC-3 Mobile Flight Mission Simulator (MFMS) has been available, which is capable of simulating a variety of enemy air vehicles. The MFMS was used by the U.S. Army in training exercises prior to 9/11. Crucially, it has been reported that “the graphic representations of MFMS tracks” on radar screens were “no different than those of actual tracks.” To distinguish between real and simulated tracks, an operator had to observe the “Identify Friend or Foe” response of a track. “Simply, a real aircraft will generate an interrogation response whereas the simulated aircraft will return no response.” [26]
If NORAD used equipment that simulated enemy aircraft in a similar way to the MFMS, this would presumably mean the task of distinguishing between real and false radar tracks on September 11 was less than straightforward, especially considering that three of the four aircraft targeted that day had their transponders turned off. [27] These aircraft would therefore not have been transmitting anything like an “Identify Friend or Foe” signal.
In sum, we need to determine the extent to which the U.S. military was hindered in its ability to respond on 9/11 as a result of its radar scopes receiving simulated information throughout the terrorist attacks.
It seems possible that the injection of false radar information could have been one way that normal emergency responses were sabotaged, so as to ensure the success of the attacks on New York and Washington, DC. If that is the case, those responsible must be investigated and brought to justice.
