Two unarmed fighter jets intercept a suspicious target flying toward the United States from the east, which turns out to be some US military aircraft returning from Europe that are unaware of the terrorist attacks in America. [9/11 Commission, 2004; Spencer, 2008, pp. 246-247] The two F-15 fighters belong to the 102nd Fighter Wing of the Massachusetts Air National Guard, and are piloted by Dennis Doonan and Joe McGrady. They were the first fighters to take off from Otis Air National Guard Base, Massachusetts, after NORAD’s Northeast Air Defense Sector (NEADS) ordered the base to launch all of its available aircraft (see (10:30 a.m.) September 11, 2001). However, the two fighters had not yet been armed.
Fighters Directed toward Target – The weapons controller the two pilots are communicating with instructs them, “Fly 090 for 100 to intercept,” meaning they are to fly east for 100 miles. Knowing his plane is unarmed, McGrady is concerned that he might have to take out their target by crashing into it. To his relief, when he gets near it, he discovers the target is a convoy of five US military aircraft: a KC-10 tanker plane and four A-10 jets. Those onboard the planes, which are returning to the US from Europe, are unaware of the catastrophic events taking place in America.
Fighters Sent toward Boston – Doonan and McGrady radio the A-10 flight lead with diversion instructions. [102nd Fighter Wing, 2001; Spencer, 2008, pp. 245-247] The A-10s are directed to land at Barnes Air National Guard Base in Massachusetts. [Richard, 2010, pp. 22] Doonan and McGrady are then instructed to fly to Boston to establish a combat air patrol over the city. Doonan decides that the KC-10 in the convoy can assist them with refueling once they are over Boston, and radios its pilot with instructions to accompany him. The pilot asks, “What’s going on?” Doonan gives no details, only replying, “It’s serious sh_t and you’re coming with us.” [Spencer, 2008, pp. 247]
Aircraft Returning from Europe – The KC-10 has the call sign “Gold 99,” while the four A-10s have the call signs “Mazda 41,” “Mazda 42,” “Mazda 43,” and “Mazda 44.” [Federal Aviation Administration, 9/11/2001; 9/11 Commission, 2004; Richard, 2010, pp. 21] The five aircraft had been on their way to Barksdale Air Force Base in Louisiana, according to author Lynn Spencer. [Spencer, 2008, pp. 247] But the FAA’s New York Center told NEADS that their planned destination was Bangor International Airport in Maine. [North American Aerospace Defense Command, 9/11/2001] According to Spencer, and also to a report written by the 102nd Fighter Wing’s historian, the aircraft have been flying to the US from the Azores, off Portugal. [102nd Fighter Wing, 2001; Spencer, 2008, pp. 247] But the New York Center indicated to NEADS that they came from Morón Air Base in southern Spain. [North American Aerospace Defense Command, 9/11/2001; International Civil Aviation Organization, 1/12/2006 
] Such journeys from Europe to the US are “common flights between the continents,” according to 102nd Fighter Wing pilot Martin Richard. [Richard, 2010, pp. 21]
Aircraft Not Answering Radio Communications – NEADS personnel were concerned because it had not been confirmed that the five aircraft were “friendly” and because the aircraft repeatedly failed to respond to NEADS’s radio communications (see (10:31 a.m.-10:47 a.m.) September 11, 2001). [North American Aerospace Defense Command, 9/11/2001] According to Spencer, the aircraft were “out of radio range.” [Spencer, 2008, pp. 247] However, NEADS personnel established that, as the aircraft had only been 174 miles away, they should have been hearing the radio communications. [North American Aerospace Defense Command, 9/11/2001]
11:06 a.m. September 11, 2001: FAA Advisory Officially Suspends Operations in US Airspace
The FAA’s Command Center in Herndon, Virginia, sends out an advisory that suspends operations in the national airspace system, requiring all aircraft to land and prohibiting aircraft from taking off from all airports. [Federal Aviation Administration, 3/21/2002; Federal Aviation Administration, 4/15/2002] At 9:26 a.m., the FAA ordered a national ground stop that prevented any aircraft from taking off (see (9:26 a.m.) September 11, 2001), and at 9:45 a.m. it instructed all airborne aircraft to land at the nearest airport (see (9:45 a.m.) September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001] According to a 2002 FAA report, “With this advisory, the shutdown of the air traffic system en masse had officially begun.” The advisory states: “Due to extraordinary circumstances and for reasons of safety. Attention all aircraft operators. By order of the Federal Aviation Command Center all airports/airdromes are not authorized for landing and takeoff. All traffic including airborne aircraft are encouraged to land shortly, including all helicopter traffic. Aircraft involved in firefighting in the Northwest US are excluded. Please read this notice over the emergency frequencies, and VOR [VHF omnidirectional range] voice.” [Federal Aviation Administration, 3/21/2002]
11:07 a.m. September 11, 2001: CNN Incorrectly Reports Possible Third Skyscraper Collapse in New York
A CNN correspondent incorrectly suggests that a third skyscraper may have recently collapsed in New York. Reporting from Lower Manhattan, Allan Dodds Frank describes: “[J]ust two or three minutes ago there was yet another collapse or explosion. I’m now out of sight, a Good Samaritan has taken me in on Duane Street. But at a quarter to 11, there was another collapse or explosion following the 10:30 collapse of the second tower. And a firefighter who rushed by us estimated that 50 stories went down. The street filled with smoke. It was like a forest fire roaring down a canyon.” [CNN, 9/11/2001] A third tower—the 47-story World Trade Center Building 7—does collapse on this day. It will not come down, however, until 5:20 in the afternoon (see (5:20 p.m.) September 11, 2001). [Washington Post, 9/12/2001; New York Times, 11/29/2001]
11:11 a.m. September 11, 2001: First DC Air National Guard Fighters with Missiles Take Off
Two District of Columbia Air National Guard (DCANG) fighter jets take off from Andrews Air Force Base, near Washington, to defend the capital, the first DCANG planes to launch armed with missiles as well as bullets. [Aviation Week and Space Technology, 9/9/2002; 9/11 Commission, 2004; 9/11 Commission, 2/17/2004; 9/11 Commission, 3/11/2004 ] The two F-16s are piloted by Captain Brandon Rasmussen and Major Daniel Caine. [Aviation Week and Space Technology, 9/9/2002] Although Caine was his unit’s supervisor of flying (SOF) this morning, he decided earlier on that he was going to get airborne, and so Lieutenant Colonel Phil Thompson has taken his place as SOF (see (Shortly After 9:35 a.m.) September 11, 2001). [Filson, 2003, pp. 76; Spencer, 2008, pp. 184]
Commander Supposedly Gave Shootdown Authority – As Caine and Rasmussen were passing the SOF area on the way to their fighters, they were quickly briefed by Brigadier General David Wherley, the commander of the DC Air National Guard. Wherley had by then received instructions from the Secret Service for his fighter jets to follow (see (10:15 a.m.) September 11, 2001 and (Between 10:16 a.m. and 10:35 a.m.) September 11, 2001). According to author Lynn Spencer, he told the two pilots: “You need to establish a CAP [combat air patrol] over Washington. Intercept any incoming aircraft 60 miles out and use whatever force necessary to keep it from targeting buildings downtown.” Wherley said, “You will be weapons free,” which means the decision whether to fire on a hostile aircraft rests with the lead pilot, and added, “Just be careful.” [9/11 Commission, 7/24/2004, pp. 44; Spencer, 2008, pp. 238] However, Rasmussen will contradict this account, saying that once he is airborne, “we still haven’t been told, ‘You are clear to engage anybody.’ They just said, ‘Get airborne as quick as you can.’” But while the two pilots were getting suited up ready to fly, Caine, who will be the flight lead, had reassured Rasmussen that he would take responsibility for firing on any hostile planes. He’d said: “Whatever you do, don’t be the first one to shoot.… Let me be the first one to shoot, if it comes to that, and then do what I do.” [Rasmussen, 9/18/2003]
Fighters Loaded with Missiles – Three DCANG jets took off from Andrews earlier on, but none of them were armed with missiles (see (10:38 a.m.) September 11, 2001 and 10:42 a.m. September 11, 2001). [Vogel, 2007, pp. 446] Missiles were loaded onto Caine and Rasmussen’s F-16s while they were sitting in the cockpits. [Aviation Week and Space Technology, 9/9/2002] Rasmussen will later recall that “we were probably 20 to 30 minutes behind” the previous two jets to launch, “because they were loading heat-seeking missiles on the aircraft.… Once they armed us up, we just rolled right down the runway and blasted off.” The jets take off with hot guns and two AIM-9 Sidewinder missiles each. According to Rasmussen, this is the first time he has flown with live missiles. He will say, “I had never flown with real missiles and had never so much as seen them on the jet.”
Communicate with FAA Controllers – After taking off, Caine and Rasmussen communicate with the FAA’s Washington Center, “primarily to control us and give us an idea of the air picture,” according to Rasmussen. The Washington Center normally controls all of the air traffic in the area. However, its controllers are not trained as weapons controllers. Rasmussen will say: “[W]e’re used to working with AWACS [Airborne Warning and Control System] weapons controllers or GCI [ground control intercept].” GCI is “a ground-based radar facility with weapons controllers who will give you the tactical air picture; control and coordinate who is targeting what aircraft; and run the air war that way.” [Filson, 2003, pp. 84; Rasmussen, 9/18/2003]
Airborne for 3-4 Hours – DCANG pilot Marc Sasseville, who took off at 10:42 a.m., was initially the CAP commander, but Caine takes over this responsibility from him once he is in the air. [9/11 Commission, 3/8/2004 ; Vogel, 2007, pp. 446] Caine and Rasmussen will remain airborne for three or four hours, which is at least twice as long as the usual maximum duration for an air-to-ground sortie, of about an hour and a half. [Rasmussen, 9/18/2003]
11:11 a.m. September 11, 2001: Attorney General Ashcroft’s Plane Diverted to Richmond, Threatened with Being Shot Down
The plane carrying Attorney General John Ashcroft, which is heading toward Washington, DC, is threatened with being shot down by the military if it does not land, and is diverted to Richmond, Virginia. [Washington Post, 9/28/2001; Federal Aviation Administration, 3/21/2002; Spencer, 2008, pp. 258] Even though the FAA had issued a national ground stop preventing aircraft from taking off (see (9:26 a.m.) September 11, 2001), Ashcroft insisted that his plane take off and fly back to Washington after it landed in Milwaukee to refuel (see After 9:37 a.m. September 11, 2001). And though the FAA has been instructing all aircraft to land at the nearest airport (see (9:45 a.m.) September 11, 2001), Ashcroft told his pilot to ignore an order to land near Detroit, and instead continue toward Washington (see 10:40 a.m. September 11, 2001). [US Congress. House. Committee On Transportation And Infrastructure, 9/21/2001; Ashcroft, 2006, pp. 117; Spencer, 2008, pp. 257-258]
Fighters Intercept Ashcroft’s Plane – When Ben Sliney, the national operations manager at the FAA’s Herndon Command Center, hears that Ashcroft’s pilot is refusing to land, he notifies NORAD’s Northeast Air Defense Sector (NEADS). As a result, two F-16 fighter jets from a nearby Air National Guard base intercept Ashcroft’s plane, but they remain out of sight and undetected by its pilot. The F-16s’ pilots report to NEADS that the errant plane is a private corporate jet without any markings, which is heading for Washington and does not seem to have any intention of landing.
Sliney Wants Plane ‘out of My Sky’ – Ashcroft’s pilot, David Clemmer, has started broadcasting a message “in the blind,” meaning it is not intended for any specific air traffic controller, stating that the attorney general is on the plane and they are returning to Washington. The F-16 pilots notify NEADS of this, but when a NEADS officer then tells Sliney about the message, Sliney asks, “Can you guarantee me that it is indeed John Ashcroft on that plane?” The officer replies, “No sir, we cannot,” and so Sliney demands, “Then get him out of my sky!” NEADS issues the order to the two F-16 pilots that if the plane will not land voluntarily, then they must take it down. The F-16 flight lead calls the FAA’s Washington Center and arranges for one of its controllers to call the plane’s pilot and tell him that if he does not divert and land, his plane will be shot down. [Spencer, 2008, pp. 258]
Pilot Warned Plane Could Be Shot Down – The Washington Center controller tells Clemmer, “Land your plane immediately, or risk getting shot down by the US Air Force.” [Newsweek, 9/24/2001] Clemmer relays this warning to Ashcroft, telling him: “Sir, there’s a shootdown order. If we get any closer to Washington, they might blow us out of the sky.” [Ashcroft, 2006, pp. 118] Clemmer also turns to an FBI agent who has been assigned to guard Ashcroft, and says, “Well, Larry, we’re in deep kimchi here, and basically, all the rules you and I know are out the window.” He tells air traffic controllers that he is carrying the attorney general, but is worried that this information won’t get through to military commanders who control the airspace around Washington. [Newsweek, 9/24/2001] Clemmer will later recall: “We didn’t want to do anything that would jeopardize our safety or the safety of the [attorney general]. I know I didn’t want to get shot down either.”
Plane Diverted to Richmond – According to some accounts, Ashcroft finally relents, and, at the insistence of the FAA, his plane is diverted to Richmond. Ashcroft will later recall, “It was a real negotiation [with the FAA].” [Washington Post, 9/28/2001; Newsweek, 3/10/2003; Spencer, 2008, pp. 258] However, according to a 2002 FAA report, Ashcroft’s plane is diverted to Richmond “due to air traffic requests for the release of medevac aircraft in the Washington, DC, area.” [Federal Aviation Administration, 3/21/2002] As the plane flies toward Richmond, Clemmer negotiates getting a fighter escort for it. Ashcroft will persist in his desire to reach Washington, and his plane will eventually be cleared to land in the capital (see 11:27 a.m. September 11, 2001). [Washington Post, 9/28/2001; Spencer, 2008, pp. 272]
Shortly After 11:11 a.m. September 11, 2001: Fighters from Richmond and Atlantic City Arrive over Washington
More fighter jets arrive over Washington, DC. These include F-16s from Richmond, Virginia, and Atlantic City, New Jersey. [Aviation Week and Space Technology, 9/9/2002] The Atlantic City jets belong to the 177th Fighter Wing (see (Shortly After 9:03 a.m.) September 11, 2001), and the Richmond jets belong to the 192nd Fighter Wing. [GlobalSecurity (.org.), 10/21/2001; Code One Magazine, 10/2002] Fighters from Langley Air Force Base in Virginia (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001) and Andrews Air Force Base, just outside Washington (see 10:42 a.m. September 11, 2001 and 11:11 a.m. September 11, 2001), are already flying over the capital. Captain Brandon Rasmussen, who took off from Andrews at 11:11 a.m., actually flies out to intercept the fighters from Richmond, apparently not realizing who they are. He will later recall: “I ended up running an intercept out of a two-ship out of Richmond, two-ship F-16 out of Richmond that just came flying north. In essence, we would find whatever we could on the radar, ask [the FAA’s] Washington Center if they knew who it was, and if they didn’t, we would run an intercept on them to visual identify who they were.” [Rasmussen, 9/18/2003] According to Aviation Week and Space Technology magazine, with jets from different units arriving over Washington, “The air picture was confused, at best, and radio frequencies were alive with chatter.” [Aviation Week and Space Technology, 9/9/2002]
11:15 a.m. September 11, 2001: Defense Secretary Rumsfeld Updates President on Rules of Engagement for Fighters and Increased Defense Readiness Condition
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 ; 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). [Sammon, 2002, pp. 112-113; American History, 10/2006 ]
11:15 a.m.-11:45 a.m. September 11, 2001: Barksdale Air Force Base Prepares for Arrival of Air Force One and President
Officials at Barksdale Air Force Base, near Shreveport, Louisiana, are informed that a large plane will be arriving unexpectedly at their base and will require security within the next 30 minutes, and they quickly deduce that the aircraft is Air Force One, the president’s plane, and start preparing for its arrival. [Associated Press, 10/2/2001; American History, 10/2006 ]
Officers Given List of Requirements for Air Force One – Colonel Anthony Imondi and Colonel Curtis Bedke of the 2nd Bomb Wing at Barksdale take a call from Air Force One in which they are given a list of requirements requested by the plane’s crew. These requirements include supplies intended to last for at least a day or two, as the president is currently uncertain of his final destination or how long he may need to remain airborne. On the list are, among other things, 150,000 pounds of fuel, 75 box lunches, 10 gallons of orange juice, bagels, muffins, and 25 pounds of bananas.
Commander Deduces Plane Is Air Force One – When Lieutenant General Thomas Keck, the commander of the 8th Air Force at Barksdale, learns of the request, he asks his staff, “Who the heck is this?” His personnel say they don’t know, as the plane would not identify itself except to say there were distinguished visitors on board and it was “Code Alpha,” which means top priority. The pilot of Air Force One, Colonel Mark Tillman, then informs the base that the distinguished visitors are four congressmen. However, Keck suspects the plane is more important and soon works out that it must be Air Force One, carrying the president. He then has just 20 minutes to prepare for the president’s arrival at Barksdale.
Base Prepares for Plane’s Arrival – Keck orders his staff to prepare for receiving a large, inbound aircraft, although he and his colleagues try to keep the plane’s identity secret as much as possible. The order goes out for the requested supplies to be gathered from the dining facility on the base, the commissary, or from off-base stores. The base’s security forces, and fuels and maintenance personnel, are instructed to stand by to service the plane. Keck tells the base’s military police unit that the incoming plane will need a full-on security detail as soon as it stops on the runway. [2d Bomb Wing, 6/30/2002 ; American History, 10/2006 ]
Officer Told Air Force One Landing at Nearby Airport – Captain Russell Stilling, an operations officer with the 2nd Security Forces Squadron at the base, is initially told only that an “unidentified aircraft” is inbound. Four minutes later he is called by the Secret Service, which tells him the aircraft is in fact Air Force One, but says the plane will be arriving at Shreveport Regional Airport, not Barksdale Air Base, and asks him to assign extra security police. Stilling only realizes Air Force One is landing at Barksdale while he is still on the phone with the Secret Service and he glances at a camera focused on the base’s runways, which is showing the plane coming in to land. [Times-Picayune, 9/8/2002] Air Force One will land at Barksdale Air Force Base at 11:45 a.m. (see 11:45 a.m. September 11, 2001). [Time, 9/14/2001]
After 11:15 a.m. September 11, 2001: Military Unit near Pentagon Prevented from Launching Helicopters to Assist Recovery
Helicopter crews with an Army aviation unit based near the Pentagon are initially unable to launch after returning from weapons training, because, they are told, they are “locked down until further notice.” [Army Center of Military History, 11/14/2001 ] The 12th Aviation Battalion is stationed at Davison Army Airfield, which is at Fort Belvoir, 12 miles south of the Pentagon. It is the Military District of Washington’s aviation support unit, and includes three helicopter companies that fly UH-1 “Huey” and UH-60 Black Hawk helicopters. [Military District of Washington, 8/2000] But at the time of the attacks on the World Trade Center, an unspecified number of the battalion’s members were away at the shooting range at Fort AP Hill, for their annual weapons training (see 8:46 a.m.-9:37 a.m. September 11, 2001). They only set out on the one and a half to two hours drive back to base after the Pentagon was hit. One of the battalion’s helicopter pilots, who says the Pentagon is “basically one of our missions,” will later recall that after arriving back at Davison Airfield, his company commander “pretty much had us all get together, and he broke us down into aviation crews… and then he briefed us on what to expect.” The battalion’s helicopters are put “online,” meaning “we preflight our aircraft, got ready, and we went ahead and took everything out.” But, the pilot will say: “then basically we were locked down until further notice. That’s what we were told. And at that point, aviation got hit the hardest, so nobody was flying anywhere unless we had specific permission.… It was a waiting game.” The first helicopter to take off from Davison Airfield transports some engineers to the Pentagon, though the time it launches at is unstated. The 12th Aviation Battalion helicopters will subsequently be involved with supporting Operation Noble Eagle, the new homeland defense mission after 9/11.

CNN reports that the Centers for Disease Control and Prevention is preparing emergency-response teams as a precaution. [CNN, 9/12/2001]
