Captain Craig Borgstrom.Captain Craig Borgstrom. [Source: US Air Force / Austin Knox]The three F-16 fighter jets ordered to scramble from Langley Air Force Base in Virginia (see 9:24 a.m. September 11, 2001) take off and, radar data will show, are airborne by 9:30 a.m. [North American Aerospace Defense Command, 9/18/2001; Christian Science Monitor, 4/16/2002; 9/11 Commission, 7/24/2004, pp. 27]
Delayed during Launch - Major Dean Eckmann will recall that, after receiving the scramble order, he and the two other pilots have “a pretty quick response time. I believe it was four to five minutes we were airborne from that point.” [BBC, 9/1/2002] According to the 1st Air Force’s book about 9/11, the three fighters are “given highest priority over all other air traffic at Langley Air Force Base” as they are launching. [Filson, 2003, pp. 63] But, according to author Lynn Spencer, in spite of this, the jets are delayed. As Eckmann is approaching the runway, he calls the control tower for clearance to take off, but the tower controller tells him, “Hold for an air traffic delay.” Air traffic controllers at the FAA’s Washington Center “have not had time to clear airliners out of the way for the northerly heading. Dozens of aircraft at various altitudes fill the jets’ route.” After having to wait two minutes, Eckmann complains: “We’re an active air scramble. We need to go now!” Finally, the tower controller tells him, “Roger, Quit flight is cleared for takeoff, 090 for 60,” meaning the fighters are to fly due east for 60 miles (see (9:30 a.m.) September 11, 2001).
Taking Off - The three jets launch 15 seconds apart, with Eckmann in front and the two other jets following. [Spencer, 2008, pp. 143-144] Pilot Craig Borgstrom will later recall, “[W]e took off, the three of us, and basically the formation we always brief on alert, we’ll stay in a two- to three-mile trail from the guy in front.” [Filson, 2003, pp. 63] According to the BBC, the pilots get a signal over their planes’ transponders, indicating an emergency wartime situation. [BBC, 9/1/2002]
Could Reach Washington before Pentagon Attack - F-16s have a maximum speed of 1,500 mph at high altitude, or 915 mph at sea level, so the three fighters could plausibly travel the 130 miles from Langley Air Force Base to Washington in just minutes. [Chant, 1987, pp. 404; Associated Press, 6/16/2000; USA Today, 9/16/2001; Washington Post, 9/16/2001 pdf file; US Air Force, 10/2007] Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will tell the 9/11 Commission, “I think if those aircraft had gotten airborne immediately, if we were operating under something other than peacetime rules, where they could have turned immediately toward Washington, DC, and gone into burner, it is physically possible that they could have gotten over Washington” before 9:37, when the Pentagon is hit. [9/11 Commission, 5/23/2003] Yet according to the 9/11 Commission, the jets are redirected east over the Atlantic Ocean and will be 150 miles from the Pentagon when it is hit (see 9:30 a.m.-9:37 a.m. September 11, 2001). [9/11 Commission, 7/24/2004, pp. 27]
Conflicting Times - Some early news reports after 9/11 will say the Langley jets take off at the later time of 9:35 a.m. [Washington Post, 9/12/2001; CNN, 9/14/2001; Washington Post, 9/15/2001; CNN, 9/17/2001] But according to Colonel Alan Scott, the former vice commander of the Continental US NORAD Region, though the jets are airborne at 9:30, the report of this does not come down until 9:35, so this fact may account for the conflicting times.

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. [9/11 Commission, 2/17/2004; 9/11 Commission, 7/24/2004, pp. 41-42]

In a phone call with Vice President Dick Cheney, President Bush authorizes the military to shoot down hostile aircraft. Minutes earlier, in the Presidential Emergency Operations Center (PEOC) below the White House, a military aide had asked Cheney for the authority to engage what appeared to be an inbound aircraft, and Cheney had promptly given it (see (Between 10:10 a.m. and 10:15 a.m.) September 11, 2001). During a subsequent quiet moment, deputy White House chief of staff Josh Bolten, who is also in the PEOC, suggested to Cheney that he contact the president to confirm the engage order. Therefore at 10:18 a.m., according to White House logs, Cheney calls Bush, who is on board Air Force One, and speaks with him for two minutes. White House press secretary Ari Fleischer notes that at 10:20 a.m., Bush informs him that he has authorized the shootdown of aircraft, if necessary. According to the 9/11 Commission, “Fleischer’s 10:20 note is the first mention of shootdown authority.” [9/11 Commission, 7/24/2004, pp. 41 and 465] Bush’s senior adviser Karl Rove, who is also on Air Force One, gives a similar account, later telling NBC News that “at about 10:20,” Bush goes from his office into the private cabin in front of it, “and took a phone call, and came back in and said that he had talked to the vice president and to the secretary of defense and gave the authorization that [the] military could shoot down any planes not under control of their crews that were gearing critical targets.” [MSNBC, 9/11/2002] But other accounts indicate the president gives the shootdown authorization earlier than this. Bush and Cheney will claim that Bush gives the authorization during a call estimated to occur between about 10:00 and 10:15 (see (Between 10:00 a.m. and 10:15 a.m.) September 11, 2001). [9/11 Commission, 7/24/2004, pp. 40] Similarly, according to journalists Bob Woodward and Bill Sammon, Bush gives it in a call with Cheney soon after 9:56, when Air Force One takes off (see (Shortly After 9:56 a.m.) September 11, 2001). [Sammon, 2002, pp. 102; Woodward, 2002, pp. 17-18; Washington Post, 1/27/2002] Counterterrorism “tsar” Richard Clarke says it is given even earlier. He states that, at some point between about 9:38 and 9:56, he is instructed to tell the Pentagon it has authorization from the president to shoot down hostile aircraft (see (9:38 a.m.) September 11, 2001 and (Between 9:45 a.m. and 9:56 a.m.) September 11, 2001).

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).

Heather Penney Garcia.Heather Penney Garcia. [Source: Johnathon Orrell]Two F-16 fighter jets belonging to the District of Columbia Air National Guard (DCANG) take off from Andrews Air Force Base, near Washington, but they have no missiles and only training bullets for their guns. The pilots are Lieutenant Colonel Marc Sasseville and Lieutenant Heather Penney Garcia. [Filson, 2003, pp. 82; 9/11 Commission, 2004; Vogel, 2007, pp. 446]
Possibly Given Shootdown Authorization - Before they headed to their jets, Sasseville and Penney Garcia were given a short briefing by Brigadier General David Wherley, the commander of the DC Air National Guard. Wherley will later recall telling Sasseville that he has “weapons free flight-lead control,” meaning he is responsible for deciding whether to fire on hostile aircraft (see (Between 9:40 a.m. and 10:35 a.m.) September 11, 2001). [Filson, 2003, pp. 82; 9/11 Commission, 7/24/2004, pp. 44; Vogel, 2007, pp. 446] But Sasseville will say he does not recall receiving any such rules of engagement until after he has taken off. [9/11 Commission, 3/8/2004 pdf file]
Jets Only Have Training Ammunition - The two pilots run out to their jets and climb into the cockpits. But their F-16s are armed only with “hot” guns and 511 rounds of non-explosive training practice (TP) ammunition. According to Sasseville: “They had two airplanes ready to go, and were putting missiles on numbers three and four. Maintenance wanted us to take the ones with missiles, but we didn’t have time to wait on those.”
Rookie Pilot 'Never Scrambled Before' - Penney Garcia, who is a rookie pilot, will later say: “I’d never scrambled before, I’d never done this. I was screaming to the maintainers to pull the chocks, and the guys were pulling the pins to arm the guns. We were going without INS [inertial navigation system].” Sasseville and Penney Garcia are airborne about six minutes after reaching their jets. They are unaware that fighters launched from Langley Air Force Base are also flying over Washington, at around 20,000 feet (see (Between 9:49 a.m. and 11:00 a.m.) September 11, 2001). [Aviation Week and Space Technology, 9/9/2002; Filson, 2003, pp. 82]
Told to Look for Hijacked Plane - Over their radios, Sasseville and Penney Garcia receive instructions from their squadron to look for a hijacked aircraft approaching from the northwest and heading toward Georgetown (see (10:30 a.m.-10:40 a.m.) September 11, 2001). But, Sasseville will later recall, “We didn’t know what we were looking for—how high he was coming, or low, or where he was going.” [Vogel, 2007, pp. 446] He will say, “I don’t have the whole picture, but have word from Washington National Approach that something is coming.”
Pilot 'Making Things Up on the Fly' - The two jets will fly over Washington at low altitudes, around 5,000 or 6,000 feet. Sasseville will later say, “I didn’t want to get too low for a good radar angle, and not too high, so we could get somewhere fast.” He will admit that he is “making things up on the fly,” as he has no precedent to draw upon. [Aviation Week and Space Technology, 9/9/2002; Filson, 2003, pp. 82] Another DCANG pilot, Billy Hutchison, launched from Andrews four minutes before Sasseville and Penney Garcia take off, but he is airborne for less than 10 minutes (see (10:38 a.m.) September 11, 2001 and 10:47 a.m. September 11, 2001). The next DCANG jets to take off, which will be armed with missiles, launch at 11:11 a.m. (see 11:11 a.m. September 11, 2001).
