Major General Larry Arnold, the commander of the 1st Air Force whose mission includes the protection of the continental US against air attacks, tells the Associated Press that he is deeply worried by the possibility of an airborne terrorist attack. He says: “I lie awake worrying. It is one thing to put a truck inside the twin trade towers and blow it up. It is quite another to be able to fly a weapon across our borders. That is an attack, a direct attack, an unambiguous attack from outside our country.” In 1999, a study commissioned by Arnold emphasized the continued importance of the Air Force’s air sovereignty mission and the threat of terrorism (see 1999). [Associated Press, 2/1/2000; Associated Press, 8/2/2002; Filson, 2003, pp. 92] As one of the top commanders of NORAD, Arnold will play a pivotal role on the morning of 9/11 (see (8:42 a.m.) September 11, 2001, (10:08 a.m.-10:10 a.m.) September 11, 2001, and 10:31 a.m. September 11, 2001).

Personnel on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) confirm to their mission crew commander (MCC) that they are prepared to issue an order to fighter pilots, telling them to fire on a commercial airliner.
MCC Concerned about Possible Shootdown - Major Kevin Nasypany, the NEADS MCC, is concerned about what might happen next as the day’s crisis unfolds. He realizes he may need to order fighter jets under his command to shoot down an errant aircraft. He therefore starts walking up and down the operations floor, impatiently asking all his section heads and weapons technicians, “Are you prepared to follow an order to shoot down a civilian airliner?” All of them affirm that they will issue such an order if required to do so.
Nasypany Confers with Marr - Satisfied with their answers, Nasypany gets on the phone to Colonel Robert Marr, who is in the NEADS battle cab, and asks him, “Have we already asked the questions?” What Nasypany means is, have they asked about getting authorization to take out a threatening aircraft? According to author Lynn Spencer, “Those authorizations, [Nasypany] knows, are going to have to come from the president himself, passed down from senior NORAD command in Colorado Springs.” Marr replies that Major General Larry Arnold, who is at the Continental US NORAD Region (CONR) headquarters in Florida, is seeking the necessary authorizations and is prepared to take any action required. Nasypany then briefs Marr on the armaments on board the fighters NEADS has had launched (see 8:46 a.m. September 11, 2001). He adds: “My recommendation, if we have to take anybody out, large aircraft, we use AIM-9s in the face. If need be.” He means that if there is another hijacking, the most effective way to bring the plane down would be to fire a missile into its nose. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 140-141]
Pilots Do Not Receive Shootdown Authorization - At around 9:35 a.m., according to Spencer, a NEADS weapons controller will ask one of the pilots that launched in response to the first hijacking whether he would be willing to shoot down a hijacked aircraft (see (9:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 153] According to the 9/11 Commission, however, NEADS personnel will only learn that NORAD has been cleared to shoot down threatening aircraft at 10:31 a.m., and even then they will not pass this order along to the fighter pilots (see 10:31 a.m. September 11, 2001).

Counterterrorism “tsar” Richard Clarke, who is in the White House Situation Room, instructs that US embassies overseas be closed and that US military bases raise their alert level. According to his own recollection, just after he has spoken to the acting Chairman of the Joint Chiefs of Staff Richard Myers (see 9:28 a.m. September 11, 2001), Clarke is thinking about the simultaneous attacks on the US embassies in Kenya and Tanzania in 1998 (see 10:35-10:39 a.m., August 7, 1998). As he describes, “There was the possibility now of multiple simultaneous attacks in several countries.” He therefore issues instructions to the State Department and the Department of Defense: “We have to assume there will be simultaneous attacks on us overseas. We need to close the embassies. Move [Department of Defense] bases to combat Threatcon.” [Clarke, 2004, pp. 5-6] (“Threatcon” is short for “terrorist threat condition.” [Slate, 9/12/2001] ) According to CNN, all US military forces will be ordered to the highest alert level at 10:10 a.m. (see (Between 10:10 a.m. and 10:35 a.m.) September 11, 2001). [CNN, 9/4/2002] But the 9/11 Commission Report will state that Secretary of Defense Donald Rumsfeld only orders the US armed forces to Defcon 3, an increased state of readiness, at 10:43 a.m. (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 326 and 554] The State Department will tell US embassies to make the decision whether to close based on their own local security requirements. Around 50 US embassies or consulates around the world will therefore close, though at what time they do so is unstated. [US Department of State, 9/12/2001]

In the middle of the 9/11 attacks, General Ralph Eberhart, the commander of NORAD, drives from his NORAD headquarters office at Peterson Air Force Base, Colorado to the NORAD operations center in Cheyenne Mountain, about a dozen miles away. The journey reportedly takes him 45 minutes and en route he loses a cell phone call with Vice President Cheney. The reason he makes this journey is unknown, though it is reported that there are superior communications capabilities available at Cheyenne Mountain. [Colorado Springs Gazette, 6/16/2006; Denver Post, 7/28/2006; Washington Post, 7/29/2006] The exact times when Eberhart departs Peterson AFB and arrives at Cheyenne Mountain are unclear. General Richard Myers says that Eberhart phones him from Peterson either just before or just after the Pentagon is hit, which suggests that Eberhart heads out some time between 9:35 a.m. and 9:40 a.m. [Armed Forces Radio And Television Service, 10/17/2001; 9/11 Commission, 6/17/2004] Eberhart tells the 9/11 Commission that when he arrives at the NORAD operations center, the order to shoot down hijacked aircraft has already been passed down NORAD’s chain of command. According to the commission’s timeline, this would indicate he arrives after 10:31 a.m. (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42] Yet other reports state that the massive blast doors to Cheyenne Mountain are shut at around 10:15 a.m. (see (10:15 a.m.) September 11, 2001), which suggests that Eberhart arrives earlier.

According to most accounts, the two fighter jets launched from Otis Air National Guard Base in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) never receive an order from the military to shoot down hostile aircraft. However, one account will suggest otherwise. [Cape Cod Times, 8/21/2002; Filson, 2003, pp. 70; 9/11 Commission, 7/24/2004, pp. 42-44; Boston Globe, 9/11/2005] According to the 9/11 Commission, personnel at NORAD’s Northeast Air Defense Sector (NEADS) learn that NORAD has been cleared to shoot down threatening aircraft at 10:31 a.m., but they do not pass this order on to the fighter pilots (see 10:31 a.m. September 11, 2001). The only order conveyed to the pilots is to “ID type and tail” of hostile aircraft. [9/11 Commission, 7/24/2004, pp. 42-43] In 2005, the Boston Globe will report that the two Otis pilots, Major Daniel Nash and Lieutenant Colonel Timothy Duffy, “stressed that they never had orders to shoot down any of the [hijacked] planes.” [Boston Globe, 9/11/2005] However, in October 2002, Duffy will tell author Leslie Filson that, while flying over Manhattan, he and Nash “were given clearance to kill over their radio frequencies, but to this day aren’t sure who gave that order. Was it NEADS or a civilian air traffic controller?” [Filson, 2003, pp. 70, 89] At around 9:35 a.m., NEADS radioed Duffy to check he would be prepared to shoot down a hijacked aircraft (see (9:35 a.m.) September 11, 2001). [Spencer, 2008, pp. 153] And at some point, a civilian air traffic controller tells the two Otis pilots that if another plane is hijacked, it will have to be shot down (see (9:59 a.m.) September 11, 2001).

The pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) hear a warning over radio that errant aircraft will be shot down, and receive an instruction from the Secret Service to protect the White House. [Spencer, 2008, pp. 222-223]
Pilots Learn of FAA Order - The three Langley fighter jets have now reached the Baltimore-Washington area. [Spencer, 2008, pp. 222] The pilots hear over their radios that the FAA has ordered all civilian aircraft to land. [New York Times, 10/16/2001] (The FAA issued this instruction at around 9:45 a.m. (see (9:45 a.m.) September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; 9/11 Commission, 7/24/2004, pp. 29] )
Borgstrom Hears Shootdown Warning - The three pilots are all on different radio frequencies, but are able to communicate between themselves on their auxiliary frequency. According to author Lynn Spencer, one of them, Captain Craig Borgstrom, hears a message over the emergency radio frequency that is in response to the FAA’s recent order: “Attention all aircraft! Attention all aircraft! You are ordered to land at the nearest suitable airport. All aircraft must land immediately. Violators will be shot down.” The source of this message is unstated. [Filson, 2003, pp. 66; Spencer, 2008, pp. 222-223] (Author Leslie Filson will describe the Langley pilots hearing what is apparently a separate but similar message later on, some time after 10:42 a.m. (see 10:05 a.m.-11:05 a.m. September 11, 2001). [Filson, 2003, pp. 82] )
Instructed to Protect the White House - Around the time Borgstrom hears this, Major Dean Eckmann, the lead Langley pilot, is on the radio with the FAA’s Washington Center. A Secret Service agent has arrived there and wants to talk to him. [Filson, 2003, pp. 68; Spencer, 2008, pp. 222-223] Eckmann then receives a garbled message over his radio, which is difficult to make out. [New York Times, 11/15/2001] The message is, “Protect the house.” Eckmann will later recall, “I took it to mean protect the White House.” [Filson, 2003, pp. 68] He notifies the two other pilots—Borgstrom and Major Brad Derrig—of this message. He tells them, “I think I just talked to the Secret Service, but I’m not sure.” [New York Times, 11/15/2001]
Possible Shootdown Order? - According to Spencer, this message means that “Unknown to NEADS” (NORAD’s Northeast Air Defense Sector), Eckmann has been “given shootdown authority directly from the Secret Service, bypassing the military chain of command.” [Spencer, 2008, pp. 223] But Borgstrom and Derrig will later say they “never received explicit orders to fire on incoming planes perceived to be hostile.” [New York Times, 11/15/2001] Borgstrom radios NEADS weapons director Steve Citino and asks for specific instructions about what to do (see 10:07 a.m. September 11, 2001). [Spencer, 2008, pp. 223] According to the 9/11 Commission, NEADS will only learn that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m., and even then it does not pass this order along to the fighter pilots under its command (see 10:31 a.m. September 11, 2001).

The air traffic control tower at Andrews Air Force Base, near Washington, DC, broadcasts regular warnings over radio that any aircraft entering the restricted airspace around the capital will be shot down, even though, according to the 9/11 Commission, the president does not authorize the shooting down of threatening aircraft until 10:18 a.m. [9/11 Commission, 2004; 9/11 Commission, 2/17/2004; 9/11 Commission, 3/11/2004 pdf file; 9/11 Commission, 7/24/2004, pp. 41] The Andrews control tower begins broadcasting warning messages over the Air Traffic Information System (ATIS) at 10:05 a.m. [9/11 Commission, 3/11/2004 pdf file] The ATIS is an automatic information system over which “[p]re-recorded airfield advisory information is automatically transmitted at timed intervals over the airways on a specific frequency.” [US Air Force, 10/1/1999 pdf file]
Planes Told They Could Be 'Shot Down' - A 9/11 Commission document summarizing key transmissions from the Andrews tower will show that warning messages are broadcast about once or twice every 10 minutes. The messages, which are all quite similar, include: “No fly notice. Remain clear of Andrews Class B airspace or you will be shot down,” and, “Any aircraft monitoring Andrews Approach Control frequency: remain clear of Andrews Class B airspace or you will be shot down.” [9/11 Commission, 2/17/2004] (Class B airspace is restricted airspace in which no one is supposed to fly without a working transponder and permission from an air traffic controller. The airspace around much of Washington is designated Class B airspace. [Washington Post, 9/12/2001; New York Times, 9/29/2001] )
Fighter Pilots Hear Warning - At least one of the warning messages is heard by District of Columbia Air National Guard (DCANG) fighter pilots who launch from Andrews Air Force Base at 10:42 a.m. (see 10:42 a.m. September 11, 2001) and by pilots launched from Langley Air Force Base by NORAD’s Northeast Air Defense Sector (NEADS) earlier on (see (9:25 a.m.-9:30 a.m.) September 11, 2001). DCANG pilots Marc Sasseville and Heather Penney Garcia are flying at low altitude over Washington, while the three Langley pilots are above them at around 20,000 feet. Although they are on different radio frequencies, both sets of pilots hear a message over a shared channel: “Attention all aircraft monitoring Andrews tower frequency. Andrews and Class Bravo airspace is closed. No general aviation aircraft are permitted to enter Class Bravo airspace. Any infractions will be shot down.” [Filson, 2003, pp. 82]
Officers Hear Warning - The warning messages are also heard by DCANG officers at Andrews. After hearing that violators of the Washington airspace will be shot down, Brigadier General David Wherley thinks to himself, “I guess that will be us doing the shooting.” [Washington Post, 4/8/2002; Vogel, 2007, pp. 446] Apparently referring to the warnings from the Andrews tower, Lieutenant Colonel Phil Thompson will later recall: “We kind of winced at that, because there are plenty of hard reasons to not shoot somebody down. We were really in an ID posture—and trying to really be careful.” [Aviation Week and Space Technology, 9/9/2002]
Shootdown Not Authorized until 10:18 - Although the first of the warnings is broadcast at 10:05 a.m., President Bush only gives authorization for hostile aircraft to be shot down at 10:18 a.m., according to the 9/11 Commission, in a phone call with Vice President Dick Cheney (see 10:18 a.m.-10:20 a.m. September 11, 2001). Furthermore, NEADS only learns that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m. (see 10:31 a.m. September 11, 2001). The 9/11 Commission document of Andrews tower transmissions will show that the warnings are broadcast until at least 11:05 a.m., although presumably they continue after that.

Two senior NORAD officials, Colonel Robert Marr and Major General Larry Arnold, have to address the possibility of issuing shootdown authorization to fighter jets under their command, after a report is received about an aircraft over the White House. [Spencer, 2008, pp. 224-225]
Aircraft over White House - Marr, the battle commander at NORAD’s Northeast Air Defense Sector (NEADS) in Rome, New York, is in the NEADS battle cab. On the NEADS operations floor, mission crew commander Major Kevin Nasypany has just learned of a report of an aircraft flying over the White House (see 10:07 a.m. September 11, 2001), and now talks to Marr over the phone. Nasypany asks: “Okay, did you hear that? Aircraft over the White House. What’s the word? Intercept and what else?” Marr has a phone to each ear and does not hear what Nasypany says. Nasypany therefore repeats, “Aircraft… over… the White House!” pausing on each word for emphasis. [Vanity Fair, 8/1/2006; Spencer, 2008, pp. 224]
Commanders Discuss Shootdown Order - The news of an aircraft over the White House forces Marr and Arnold, with whom he has been communicating, to address the issue of authorizing the shooting down of aircraft. [Spencer, 2008, pp. 225] Arnold, the commander of NORAD’s Continental US Region (CONR), is at the CONR air operations center at Tyndall Air Force Base in Florida. [Code One Magazine, 1/2002] According to author Lynn Spencer, he has not yet received any instructions from his higher-ups regarding shootdown authorization. “He talked to Major General Rick Findley,” who is at NORAD’s operations center in Colorado, “and asked him to get shootdown authority from the vice president, but he’s still heard nothing back.” [Spencer, 2008, pp. 225]
Arnold Possibly Authorizes Shootdown - Arnold will later tell author Leslie Filson that he has “the authority in case of an emergency to declare a target hostile and shoot it down under an emergency condition.” [Filson, 2003, pp. 75] But according to Vanity Fair, he only passes the current request for rules of engagement further up his chain of command. [Vanity Fair, 8/1/2006] However, Spencer will claim otherwise, stating, “In light of the imminent attack on the White House,” Arnold “decides he will exercise the authority he has to protect the nation in an emergency.” He tells Marr: “We will intercept and attempt to divert. If we can’t, then we’ll shoot it down.” [Spencer, 2008, pp. 225]
Alleged Shootdown Authorization Not Passed On - Minutes later, though, Nasypany will tell his staff that the pilots that took off from Langley Air Force Base (see (9:25 a.m.-9:30 a.m.) September 11, 2001) have “negative clearance to shoot” aircraft over Washington (see 10:10 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 31] And according to the 9/11 Commission, NEADS only learns that NORAD has been given clearance to shoot down threatening aircraft at 10:31 a.m., and even then it does not pass this order along to the fighter pilots under its command (see 10:31 a.m. September 11, 2001).

US military installations are placed on the highest state of alert, known as Force Protection Condition Delta (FPCON Delta), in response to the terrorist attacks in New York and at the Pentagon. The raised threat level applies to every US military installation across the country and around the world, and every member of the US armed forces. [Associated Press, 9/11/2001; US Department of Defense, 9/11/2001; New York Times, 9/12/2001] Measures that are taken once FPCON Delta has been declared include placing more guards on duty at installations, having all vehicles on installations identified, and having all personnel positively identified. Additionally, all suitcases, briefcases, and packages brought into an installation must be searched. [Slate, 9/12/2001]
Rumsfeld and Myers Decide to Raise FPCON - The decision to raise the force protection condition is apparently made by Secretary of Defense Donald Rumsfeld and/or acting Chairman of the Joint Chiefs of Staff Richard Myers. Rumsfeld will tell the 9/11 Commission that after he arrives at the Pentagon’s National Military Command Center (NMCC) (see (10:30 a.m.) September 11, 2001), he and Myers “discussed, and I recommended… increasing the force protection level.” [9/11 Commission, 3/23/2004] Myers will later write that after he arrives at the NMCC (see (Between 9:55 a.m. and 10:25 a.m.) September 11, 2001), he “recommended that all American military commands and units worldwide go to [FPCON] Delta.” He will add: “Terrorists had staged major attacks in New York and Washington. Although we did not yet have reliable intelligence on when and where they would strike next, it seemed likely that they would.” [Myers, 2009, pp. 153] But White House counterterrorism chief Richard Clarke will write that he gave the instruction to raise the force protection condition, at around 9:30 a.m. (see (9:29 a.m.) September 11, 2001). [Clarke, 2004, pp. 5-6]
Conflicting Times Given for Raising of FPCON - The exact time at which the force protection condition is raised is unclear. CNN’s Barbara Starr will report that “all US military forces [are] ordered to Condition Delta” at 10:10 a.m. [CNN, 9/4/2002] However, other evidence indicates the force protection condition is raised at a later time, around 10:35 a.m. Rumsfeld only enters the NMCC at about 10:30 a.m., indicating it is raised after that time. [9/11 Commission, 7/24/2004, pp. 43-44] And at 10:38 a.m., after Vice President Dick Cheney asks him on the air threat conference call if US forces are on “heightened alert,” Rumsfeld will reply, “Yes,” and say they are at FPCON Delta. [US Department of Defense, 9/11/2001 pdf file]
Some Areas Already at FPCON Delta - Although the entire US military is now under the same FPCON level, usually, different locations can have different FPCON levels. [Slate, 9/12/2001] US forces in some parts of the world, particularly the Middle East and the Persian Gulf region, are in fact already at FPCON Delta. [New York Times, 9/12/2001] (The force protection condition was raised in those areas in late June, after intelligence reports suggested that terrorists might attack American military or civilian targets in the region (see June 21, 2001). [Los Angeles Times, 6/23/2001; National Public Radio, 5/23/2002; 9/11 Commission, 7/24/2004, pp. 257] ) Shortly after the force protection condition is raised, Rumsfeld will order that the defense readiness condition also be raised (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 326, 554]
Five Possible Force Protection Conditions - The force protection condition is a “chairman of the Joint Chiefs of Staff-approved standard for identification of, and recommended responses to, terrorist threats against US personnel and facilities,” according to the Department of Defense. [US Department of Defense, 11/8/2011 pdf file] It was created in June 2001 and replaced the “terrorist threat condition,” or “Threatcon.” [Los Angeles Times, 1/22/2002] There are five possible force protection conditions. The lowest, FPCON Normal, means no threat of terrorist activity is present. The other conditions are Alpha, Bravo, Charlie, up to the highest, FPCON Delta, which means a terrorist attack has occurred or intelligence has been received indicating that action against a specific location is likely.

A lieutenant colonel at the White House repeatedly relays to the National Military Command Center (NMCC) at the Pentagon that Vice President Dick Cheney has confirmed that fighter jets are cleared to engage an inbound aircraft if they can verify that the aircraft is hijacked. The lieutenant colonel notifies the NMCC of the authorization over the air threat conference call (see 9:29 a.m.-9:34 a.m. September 11, 2001). Cheney, who is in the Presidential Emergency Operations Center (PEOC) below the White House, said at sometime between 10:10 and 10:15 that fighters could engage an aircraft that was reportedly approaching Washington (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). However, it is only when Cheney calls President Bush at 10:18 a.m. that Bush confirms the shootdown order (see 10:18 a.m.-10:20 a.m. September 11, 2001). The shootdown order will be received by NORAD, and then, at 10:31 a.m., sent out to its three air defense sectors in the continental US (see 10:31 a.m. September 11, 2001).

A message is put out on NORAD’s computer chat system, notifying its three air defense sectors in the US that peacetime rules of engagement (ROE) still apply, which means fighter jets are not permitted to shoot down hostile aircraft. As a 9/11 Commission memorandum will later describe, on the chat log it is reiterated at this time “that the defensive posture [is] still peacetime ROE.” The person or organization that issues this message is unstated. NORAD’s computer chat system allows those with the proper access to communicate with each other, similarly to the way members of the public do in Internet chat rooms. The NORAD system includes three main chat rooms. The message about the current rules of engagement goes out in the chat room for the Continental US NORAD Region (CONR). This is where CONR’s three sectors—including the Northeast Air Defense Sector (NEADS), which has been coordinating the military’s response to the hijackings—communicate with each other. [9/11 Commission, 1/22/2004 pdf file; Spencer, 2008, pp. 139] It is not until 10:31 a.m. that Major General Larry Arnold, the CONR commander, will issue an instruction over the chat system, stating that NORAD has been cleared to shoot down threatening aircraft (see 10:31 a.m. September 11, 2001).

Defense Secretary Donald Rumsfeld, missing for at least 30 minutes, finally enters the NMCC, where the military’s response to the 9/11 attacks is being coordinated. [CNN, 9/4/2002; 9/11 Commission, 6/17/2004] Rumsfeld later claims that he only started to gain a situational awareness of what was happening after arriving at the NMCC. [9/11 Commission, 6/17/2004] Rumsfeld was in his office only 200 feet away from the NMCC until the Pentagon crash at 9:37 a.m. (see 9:37 a.m. September 11, 2001). His activities during this period are unclear. He went outside to the Flight 77 crash site and then stayed somewhere else in the Pentagon until his arrival at the NMCC. Brigadier General Montague Winfield later says, “For 30 minutes we couldn’t find him. And just as we began to worry, he walked into the door of the [NMCC].” [ABC News, 9/11/2002] Winfield himself apparently only shows up at the NMCC around 10:30 a.m. as well.

The Continental United States NORAD Region (CONR) issues a message to its three air defense sectors—including the Northeast Air Defense Sector (NEADS)—stating that Vice President Dick Cheney has authorized it to shoot down suspicious aircraft.
Order Sent over Computer Chat System - About 15 minutes earlier, a military officer at the White House relayed to the Pentagon’s National Military Command Center (NMCC) that Cheney had confirmed that fighter jets were cleared to engage an inbound aircraft if they could verify that the aircraft was hijacked (see 10:14 a.m.-10:19 a.m. September 11, 2001). According to the 9/11 Commission, “It is not clear how [this] shootdown order was communicated within NORAD.” However, Major General Larry Arnold, the CONR commander, now instructs his staff to broadcast a message over a NORAD computer chat system, passing on Cheney’s authorization. The message states, “10:31 Vice president has cleared to us to intercept tracks of interest and shoot them down if they do not respond, per CONR CC [General Arnold].” The message is received at CONR’s three air defense sectors: the Western, Southeast, and Northeast. [9/11 Commission, 7/24/2004, pp. 42; Spencer, 2008, pp. 240]
Arnold Could Issue Shootdown Order Himself - Arnold, who is at the CONR air operations center at Tyndall Air Force Base in Florida, will later comment, “I have the authority in case of an emergency to declare a target hostile and shoot it down under an emergency condition… but it was comforting to know we legally had the authority from the president of the United States.” [Filson, 2002; Code One Magazine, 1/2002; Filson, 2003, pp. 75-76] The 10:31 chat message is the first notification personnel on the NEADS operations floor receive of the shootdown order. These personnel are reportedly confused over the order and do not pass it on to fighter pilots under their command (see 10:32 a.m. September 11, 2001).

Personnel on the operations floor at NORAD’s Northeast Air Defense Sector (NEADS) are confused over the nature and effect of an order they have received, which states that the military can shoot down aircraft that do not respond to its directions, and they do not pass this order on to fighter pilots under their command. [9/11 Commission, 7/24/2004, pp. 42-43; 9/11 Commission, 8/26/2004, pp. 47 pdf file; Spencer, 2008, pp. 240-241; Farmer, 2009, pp. 228-229] NEADS has just received a message over the NORAD computer chat system from Larry Arnold, the commander of the Continental United States NORAD Region (CONR), stating that Vice President Dick Cheney has authorized NORAD to shoot down suspicious aircraft (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42]
Weapons Director Alerted to Order - Major Steve Ovens sees the chat message and alerts Major James Fox, the leader of the NEADS weapons team, to it. Ovens says: “We need to read this. Region commander has declared that we can shoot down tracks that do not respond to our direction. Okay?” Fox replies, “Okay,” but Ovens is unconvinced that he has understood Arnold’s message, so he says again, “The region commander has declared that we can shoot down aircraft that do not respond to our directions, okay?” Fox replies, “Copy that.”
NEADS Director Opposes Order - Ovens continues, “So if you’re trying to divert somebody and he won’t divert…” but Fox says, “DO [the director of operations] is saying no.” According to author Lynn Spencer, Fox means that Colonel Lanny McNeely, the NEADS director of operations, is indicating “no.” McNeely has “understood that the battle staff wanted to keep shootdown authority in the [NEADS] battle cab. The commanders were not prepared to pass such authorizations to airborne fighters.” [North American Aerospace Defense Command, 9/11/2001; Spencer, 2008, pp. 240-241] However, a 9/11 Commission memorandum will state that McNeely is away from NEADS on this day, in Texas, and no one is currently sitting in the director of operations position. [9/11 Commission, 10/30/2003 pdf file] According to John Farmer, the senior counsel to the 9/11 Commission, Fox is instead referring to Colonel Robert Marr, the NEADS battle commander, saying “no,” not McNeely. [Farmer, 2009, pp. 229]
Fox Agrees to Pass on Order to Commander - Ovens responds: “No? It came over the chat.… You got a conflict on that direction?” Fox replies, “Right now, no, but…” Showing Fox the chat message, Ovens says: “Okay. You read that from the vice president, right? Vice president has cleared…” Fox reads the message out loud, saying, “Vice president has cleared us to intercept traffic and shoot them down if they do not respond, per CONR CC.” Finally, he says, “Okay, I will pass it to MCC,” meaning Major Kevin Nasypany, the NEADS mission crew commander. [North American Aerospace Defense Command, 9/11/2001; Spencer, 2008, pp. 241]
NEADS Does Not Pass on Order to Pilots - NEADS personnel will later express to the 9/11 Commission their “considerable confusion over the nature and effect” of this shootdown order, and explain why they fail to pass it on to the fighter jets from Otis Air National Guard Base (see 8:46 a.m. September 11, 2001) and Langley Air Force Base (see 9:24 a.m. September 11, 2001) that are under their command. Nasypany and Fox indicate to the Commission that “they did not pass the order to the fighters circling Washington and New York because they were unsure how the pilots would, or should, proceed with this guidance.” Consequently, “while leaders in Washington believed that the fighters above them had been instructed to ‘take out’ hostile aircraft, the only orders actually conveyed to the pilots were to ‘ID type and tail.’” [9/11 Commission, 7/24/2004, pp. 43; Farmer, 2009, pp. 229]

The FAA’s Cleveland Center has to authorize two Ohio Air National Guard fighter jets to shoot down threatening aircraft, because NORAD’s Northeast Air Defense Sector (NEADS) is unable to communicate directly with those jets and give them the authorization itself. [Spencer, 2008, pp. 241-242] The two F-16s, which belong to the 180th Fighter Wing of the Ohio Air National Guard, took off from Toledo Express Airport at 10:17 a.m. (see 10:17 a.m. September 11, 2001). [Toledo Blade, 12/9/2001; WTOL, 9/11/2006]
NEADS Unable to Contact Fighters - NEADS has just received a message, informing it that Vice President Dick Cheney has authorized NORAD to shoot down suspicious aircraft (see 10:31 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 42] A weapons officer wants to pass this important information to the two 180th FW fighter pilots. However, since the jets took off, NEADS has been unable to bring them up on their UHF frequency, and so the weapons officer has had to communicate with them indirectly, via the FAA’s Cleveland Center. He now phones the Cleveland Center and asks it to pass on the new rules of engagement to the 180th FW pilots.
Controller Passes on Shootdown Authorization - A Cleveland Center air traffic controller then radios one of those pilots, Scott Reed, and asks him, “Sting 1-1 [Reed’s call sign], Cleveland Center, do you know what your ROE is?” Reed is surprised to hear a civilian controller use the military acronym for “rules of engagement.” He responds, “Sting 1-1, no.” The controller asks, “Would you like to know?” and then tells Reed, “Sting 1-1, if you have a non-military aircraft moving toward a population center, you are clear to engage.” Reed says, “Cleveland Center, Sting 1-1, please confirm ROE.” The controller responds, “Sting 1-1, if the airplane you are vectored against does not comply with your instructions, you are cleared to engage.” According to author Lynn Spencer, Reed “is shocked; he’s just been given clearance—from a civilian controller—to shoot down a commercial airliner.” [Spencer, 2008, pp. 241-242] The two 180th FW jets never receive any subsequent orders to engage specific aircraft. According to NEADS battle commander, Colonel Robert Marr, the pilots “never had a track close enough that they were directed to engage. [But] if a valid direction had come from the appropriate level to engage a target, or shoot down a target at some time, they could have done that.” [Toledo Blade, 12/9/2001] Though it notifies the 180th FW jets, NEADS fails to pass on the shootdown authorization to the fighters from Otis Air National Guard Base and Langley Air Force Base that are under its command (see 10:32 a.m. September 11, 2001).

Vice President Dick Cheney tries to bring Defense Secretary Donald Rumsfeld up to date over the National Military Command Center’s (NMCC) conference call (see 9:29 a.m.-9:34 a.m. September 11, 2001), as Rumsfeld arrived at the NMCC just minutes earlier (see (10:30 a.m.) September 11, 2001). Cheney explains that he has given authorization for hijacked planes to be shot down and that this has been passed on to the fighter pilots. Rumsfeld asks, “So we’ve got a couple of aircraft up there that have those instructions at the present time?” Cheney replies: “That is correct. And it’s my understanding they’ve already taken a couple of aircraft out.” Then Rumsfeld says: “We can’t confirm that. We’re told that one aircraft is down but we do not have a pilot report that they did it.” Cheney is incorrect about his authorization having reached the pilots (see 10:31 a.m. September 11, 2001).

The US military’s defense readiness condition is raised from Defcon 5, the lowest possible level, to Defcon 3, an intermediate level that requires a heightened alert status for US armed forces worldwide, and which is the highest the defense readiness condition has been for 28 years. [Historical Office, Office of the Secretary of Defense, 7/18/2002; 9/11 Commission, 7/24/2004, pp. 326, 554; Goldberg et al., 2007, pp. 131; Rumsfeld, 2011, pp. 338]
Rumsfeld Recommends Raising Defcon - The decision to go to Defcon 3 is reportedly made by Secretary of Defense Donald Rumsfeld. [US Department of Defense, 8/12/2002] Rumsfeld will later recall that after he arrives at the Pentagon’s National Military Command Center (NMCC) (see (10:30 a.m.) September 11, 2001), he talks with General Richard Myers, the vice chairman of the Joint Chiefs of Staff, and “[w]e discussed and I recommended raising the defense condition level from five to three.” [9/11 Commission, 3/23/2004]
Teleconference Participants Told to 'Hold Off' on Defcon 3 - Rumsfeld directs that the US military go to Defcon 3. At 10:43 a.m., it is announced on the air threat conference call that the secretary of defense “has directed that we go to Defcon 3 and be prepared to go to [Defcon] 2.” However, a minute later, Rumsfeld talks to Vice President Dick Cheney on the conference call, and Cheney says he will have to run the decision to go to Defcon 3 by the president, “and let him make the call.” Therefore, at 10:45 a.m., those on the conference call are told to “hold off on Defcon 3.”
Order to Raise Defcon Reinstated - But Rumsfeld believes raising the defense readiness condition is urgent. [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 326, 554] There is therefore a “historical discussion about how the move to Defcon 3 went during previous crises, Cuba specifically [i.e. the Cuban missile crisis in 1962],” Captain Charles Leidig, who is also in the NMCC, will later recall. With their reference being “a book on the shelf,” according to Leidig, Myers is shown that he has “approval authority to go to Defcon 3.” [9/11 Commission, 4/29/2004 pdf file] After consulting Defense Department directives, Rumsfeld concludes that he has the authority to issue the order to raise the defense readiness condition. [9/11 Commission, 7/24/2004, pp. 554] Therefore, at 10:46 a.m., those on the air threat conference call are told: “Override last instructions. The vice chairman [i.e. Myers] is directing we go to Defcon 3.” A few minutes later, an announcement is made on the conference call, “Emergency action message released at 14:52 [Zulu time, i.e. 10:52 a.m. Eastern time], re: Defcon 3.” [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 2004]
Raising Defcon Is a 'Huge Move' - Rumsfeld will later agree with an interviewer that raising the defense readiness condition is “a very serious step for the nation.” [US Department of Defense, 8/12/2002] It was last raised to Defcon 3 during the 1973 Arab-Israeli war, when Rumsfeld had been the United States ambassador to NATO. Regarding the decision to raise it, Myers tells Rumsfeld, “It’s a huge move, but it’s appropriate.” [US Department of Defense, 1/9/2002; Wall Street Journal, 3/22/2004 pdf file; Rumsfeld, 2011, pp. 338]
President Later Told of Decision - The decision to go to Defcon 3 will soon be communicated within NORAD (see 11:03 a.m.-11:12 a.m. September11, 2001). [9/11 Commission, 6/17/2003; 9/11 Commission, 2004; 9/11 Commission, 2/3/2004 pdf file] Rumsfeld will brief President Bush on the decision (see (11:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 554; Bush, 2010, pp. 133] Apparently around the time the defense readiness condition is raised, Rumsfeld and/or Myers also decide to raise the force protection condition of US military installations (see (Between 10:10 a.m. and 10:35 a.m.) September 11, 2001). [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 3/23/2004; Myers, 2009, pp. 153]
Defcon 3 Intended for Cold War - Some individuals will later be critical of the decision to raise the defense readiness condition at this time. John Farmer, the senior counsel to the 9/11 Commission, will write that Defcon 3 is in fact “a Cold War-era designation, devised to respond to a nuclear threat.” [Farmer, 2009, pp. 235] According to Farmer and other 9/11 Commission staffers, it is “suited more to a Cold War conflict than to al-Qaeda’s attack.” [Rutgers Law Review, 9/7/2011 pdf file] General Ralph Eberhart, the commander of NORAD, will similarly say that Defcon 3 is “not intended for [events like] the attacks of 9/11 and thus could have complicated the response to the attacks.” He will say he does not think that raising the condition would have “done anything for us” within the continental United States. [9/11 Commission, 3/1/2004, 3/1/2004 pdf file]
Defcons Are Phased Increases in Combat Readiness - The defense readiness condition is a “uniform system of progressive alert postures for use between the chairman of the Joint Chiefs of Staff and the commanders of unified and specified commands, and for use by the [armed] services,” according to the Department of Defense. [US Department of Defense, 11/8/2011 pdf file] Defcons are phased increases in combat readiness and are graduated to match situations of varying military severity. They are numbered, from Defcon 5, which means “normal peacetime readiness,” down to Defcon 1, which means “maximum force readiness.” The current level, Defcon 3, represents an “increase in force readiness above normal readiness.” [Federation of American Scientists, 4/29/1998] The defense readiness condition will remain at Defcon 3 until three days later, when it will be reduced one notch, to Defcon 4 (see September 14, 2001).

[Source: NORAD]The message goes out within NORAD that the military’s defense readiness condition has been raised to Defcon 3. [9/11 Commission, 6/17/2003; 9/11 Commission, 2004] Secretary of Defense Donald Rumsfeld directed that the defense readiness condition be raised from Defcon 5—the lowest level—to Defcon 3 at around 10:45 a.m. (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 326, 554; Goldberg et al., 2007, pp. 131] At 10:52 a.m., an emergency action message about the increased defense readiness condition was issued. [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 2004]
NORAD Personnel Learn of Defcon Change - Word of the change is then communicated within NORAD. At 11:03 a.m., NORAD’s Northeast Air Defense Sector (NEADS) is ordered to Defcon 3. Four minutes later, at 11:07 a.m., Lieutenant Colonel Steve Usher, the director of combat operations at the headquarters of the Continental United States NORAD Region (CONR) in Florida, announces that Defcon 3 has been ordered. [9/11 Commission, 6/17/2003] And a military log will state that “NORAD has directed Defcon change” at 11:12 a.m. [9/11 Commission, 2004] Staff Sergeant Brent Lanier, an emergency action controller in NORAD’s Cheyenne Mountain Operations Center (CMOC) in Colorado, is tasked with sending out a message about the change to the defense readiness condition. He will later recall: “I’d sent out false Defcon messages during exercises, but I never thought I’d have to send out an actual Defcon change message—but I did. It was frightening.” [Airman, 3/2002]
NORAD Officers Discuss Defcon Change - Major General Larry Arnold, the CONR commander, will tell the 9/11 Commission that he hears of the change to the defense readiness condition either from Major General Rick Findley, the director of operations at the CMOC, or from one of NORAD’s computer chat logs. [9/11 Commission, 2/3/2004 pdf file] Usher will tell the 9/11 Commission that the instruction to raise the defense readiness condition comes either from the CONR Regional Air Operations Center or from Arnold. He will add that there is an emergency action message confirming the transition. [9/11 Commission, 2/4/2004 pdf file] Arnold will recall that, at some unspecified time, he calls General Ralph Eberhart, the commander of NORAD, about the change to the defense readiness condition, with the intention of informing Eberhart “of what was ongoing.” [9/11 Commission, 2/3/2004 pdf file]
Change in Defcon Affects Who Can Declare a Target Hostile - Steve Hedrick, an air weapons officer at NEADS, will tell the 9/11 Commission that “any change in Defcon is authenticated immediately” with the fighter jets under NORAD control. He will also say that “the main change when a Defcon level changes is in who has the authority to declare a target hostile.” Hedrick will note that the order from Vice President Dick Cheney, that NORAD fighters were “cleared… to intercept tracks of interest and shoot them down if they do not respond” (see 10:31 a.m. September 11, 2001), is “distinct and different from the transition in Defcon levels.” [9/11 Commission, 10/27/2003 pdf file; 9/11 Commission, 7/24/2004, pp. 42]

Secretary of Defense Donald Rumsfeld speaks with President Bush, and they discuss the rules of engagement for fighter pilots and Rumsfeld’s decision to raise the defense readiness condition to Defcon 3. [9/11 Commission, 7/24/2004, pp. 465, 554] Rumsfeld is in the National Military Command Center (NMCC) at the Pentagon and Bush is on board Air Force One, flying toward Barksdale Air Force Base in Louisiana. [9/11 Commission, 3/23/2004; St. Petersburg Times, 7/4/2004] After Rumsfeld entered the NMCC at around 10:30 a.m. (see (10:30 a.m.) September 11, 2001), he had been concerned with ensuring that fighter pilots defending US airspace have a clear understanding of their rules of engagement, so they know “what they could and could not do” (see (10:30 a.m.-1:00 p.m.) September 11, 2001). [9/11 Commission, 3/23/2004; 9/11 Commission, 7/24/2004, pp. 43-44] He also directed that the nation’s armed forces go to Defcon 3, an increased state of military readiness (see (10:43 a.m.-10:52 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 326; Goldberg et al., 2007, pp. 131]
President Approves Decision to Raise Defcon - Rumsfeld now speaks with Bush and, according to the 9/11 Commission Report, tells him that the Department of Defense is “working on refining the rules of engagement, so pilots would have a better understanding of the circumstances under which an aircraft could be shot down.” Also at this time, according to the 9/11 Commission Report, Rumsfeld briefs Bush on his decision to raise the defense readiness condition to Defcon 3. When Rumsfeld ordered that the condition be raised, Vice President Dick Cheney told him to run the issue by the president; Rumsfeld replied that he would “call him shortly.” [US Department of Defense, 9/11/2001 pdf file; 9/11 Commission, 7/24/2004, pp. 465, 554] Bush gives Rumsfeld his approval for having raised the defense readiness condition. [Washington Post, 9/12/2001; Bush, 2010, pp. 133]
Defense Readiness Condition Possibly Discussed at Later Time - Although the 9/11 Commission Report will say Rumsfeld and Bush’s discussion of the defense readiness condition occurs at 11:15 a.m., in his 2010 book Decision Points, Bush will write that he approves Rumsfeld’s decision when he speaks to Rumsfeld from the office of Lieutenant General Thomas Keck at Barksdale Air Force Base. [Bush, 2010, pp. 133] If correct, this would mean the relevant phone call takes place sometime after 12:11 p.m., when Bush goes to Keck’s office (see (12:11 p.m.-1:20 p.m.) September 11, 2001).
