At some point between the collapse of the two WTC towers, it is claimed that fire chiefs order the firefighters to come down. It has not been reported exactly who issued this order or when. Witnesses claim that scores of firefighters, unaware of the danger, were resting on lower floors in the minutes before the second tower collapsed. “Some firefighters who managed to get out said they had no idea the other building had already fallen, and said that they thought that few of those who perished knew.” At least 121 firefighters in the remaining tower die. The Fire Department blames a faulty radio repeater. However, the Port Authority claims later transcripts of radio communications show the repeaters worked. [New York Times, 11/9/2002]
10:00 a.m. September 11, 2001: NEADS Commander Complains about Senior Officer Interfering on Operations Floor
Major Kevin Nasypany, the mission crew commander at NORAD’s Northeast Air Defense Sector (NEADS), complains about Lieutenant Colonel Ian Sanderson—an officer from the NEADS battle cab—spending time on the operations floor, where, Nasypany says, he has been “circumventing my system.” [North American Aerospace Defense Command, 9/11/2001] Sanderson is the NEADS Sector Operations Control Center (SOCC) director. He is also beginning his training as a fighter director on this day. [9/11 Commission, 10/29/2003
] He is one of a number of senior personnel working in the battle cab, which is a glass-walled room overlooking the NEADS operations floor. [Filson, 2003, pp. 55; 9/11 Commission, 10/30/2003
] However, he has also been spending time on the operations floor.
Director Is ‘Circumventing My System’ – Nasypany therefore now complains, “Got to get Ian [Sanderson] off the floor.” He adds that Sanderson has been “on it, circumventing my system here.” [North American Aerospace Defense Command, 9/11/2001] (As the mission crew commander (MCC), Nasypany is supposed to be in charge of the entire operations floor. [Spencer, 2008, pp. 25] ) He continues with his complaint, saying that Sanderson is “not an MCC” and so he “needs to stay up there” in the battle cab. [North American Aerospace Defense Command, 9/11/2001]
Director Says He ‘Did Not Interfere’ – Despite Nasypany’s grievance that he has been “circumventing my system,” Sanderson will tell the 9/11 Commission that his “first inclination” after the first World Trade Center tower was hit had been to “step back and let everyone do their jobs.” He will say that in “wartime”—presumably referring to situations like the present crisis—“there really is no function for the SOCC director.” His role on this day is therefore, partly, “to stay out of everyone’s way.” Sanderson will also say he is “parental” to the NEADS personnel, and, in contrast with Nasypany’s complaint about him, will say he “did not interfere.”
Director Responsible for Recalling Off-Duty Personnel – The SOCC director, according to Sanderson, serves as “an internal look at the operations on the SOCC [operations] floor,” and “involves manning and procedures of floor operations.” On this day, Sanderson is responsible for ensuring that the operations floor has additional personnel, and for coordinating fighter jets from bases that are not NORAD assets. Sanderson will say he is “primarily concerned with calling back the operations personnel” who are off duty. [9/11 Commission, 10/29/2003

Shortly After 9:59 a.m. September 11, 2001: Fire Department Expert on Building Collapses Thinks Bombs Caused South Tower to Come Down
When the WTC’s South Tower collapses, Father John Delendick—one of New York Fire Department’s chaplains—runs down a ramp to the garages below the nearby World Financial Center, to escape the dust cloud. He speaks there with Fire Chief Ray Downey, and asks him if the jet fuel from the plane had blown up, causing the collapse. [City of New York, 12/6/2001] Downey is in fact a renowned expert on building collapses. Robert Ingram, a battalion chief in the New York Fire Department later refers to him as “the premiere collapse expert in the country.” [US Congress. Senate. Committee on Commerce, 10/11/2001
] 9/11 Commissioner Timothy Roemer calls Downey a “very, very respected expert on building collapse.” [9/11 Commission, 5/18/2004] And Fire Chief Mike Antonucci, who is a best friend of Downey’s, says he “was probably the most knowledgeable person on building collapses there was. That was his [hobby], to study building collapses—what affected the engineering of buildings, how they [would] weaken and how he could respond and stay safe.” [Inland Valley Daily Bulletin, 9/7/2006] In response to Delendick’s question, Downey replies that, “at that point he thought there were bombs up there because [the collapse] was too even.” [City of New York, 12/6/2001] Earlier on, Downey told other fire chiefs responding at the WTC that he was worried about “explosive devices” in the Twin Towers “that could hurt the firemen” (see (9:20 a.m.) September 11, 2001). He is killed when the North Tower collapses at 10:28 a.m. [New York Times, 9/9/2005]
10:00 a.m. September 11, 2001: Alert Fighters at Tyndall Air Base Do Not Launch to Escort Air Force One
Although the White House has requested a fighter escort for Air Force One (see 9:59 a.m. September 11, 2001), fighter jets that are kept on alert at Tyndall Air Force Base in Florida reportedly fail to launch in order to accompany the president’s plane after it takes off from Sarasota, Florida (see 9:54 a.m. September 11, 2001). [Filson, 2003, pp. 87; St. Petersburg Times, 7/4/2004; 9/11 Commission, 7/24/2004, pp. 38]
Fighters on ‘Battle Stations’ but Not Launched – The 148th Fighter Wing of the Minnesota Air National Guard has a full time active duty detachment at Tyndall Air Force Base, near Panama City. [Filson, 1999; US Air Force, 2004; GlobalSecurity (.org), 8/21/2005] This unit serves as one of NORAD’s seven “alert” sites around the US, which all have a pair of fighter jets on the runway, armed, fueled, and ready to take off within minutes if called upon. [Airman, 12/1999; Air Force Magazine, 2/2002; Bergen Record, 12/5/2003] But, according to the 1st Air Force’s book about 9/11, although NORAD’s Southeast Air Defense Sector (SEADS) puts the alert jets at Tyndall on “battle stations,” it does not launch them. The jets’ pilots sit “in their cockpits awaiting word to go, but Air Force One moved so quickly they were never scrambled.” Instead, F-16s from Ellington Field in Texas are scrambled, and escort Air Force One to Barksdale Air Force Base (see (After 9:56 a.m.) September 11, 2001 and (11:29 a.m.) September 11, 2001). [Filson, 2003, pp. 87] However, in a 2002 interview, Major General Larry Arnold, the commanding general of NORAD’s Continental US Region, will claim that after NORAD is told “just to follow the president” on Air Force One, it “scrambled available airplanes from Tyndall and then from Ellington in Houston, Texas. The Ellington F-16s chased Air Force One and landed with the president at Barksdale AFB in Louisiana.” [Code One Magazine, 1/2002]
Other Alert Fighters in Florida Not Launched – NORAD also keeps two fighters on alert at Homestead Air Reserve Base, near Miami, Florida, but it is unclear whether these are scrambled after Air Force One, and apparently they never accompany the president’s plane (see (10:00 a.m.) September 11, 2001). Philip Melanson, an expert on the Secret Service, will later comment: “I can’t imagine by what glitch the protection was not provided to Air Force One as soon as it took off. I would have thought there’d be something in place whereby one phone call from the head of the security detail would get the fighters in the air immediately.” [Filson, 2003, pp. 87; St. Petersburg Times, 7/4/2004]
Around 10:00 a.m. September 11, 2001: Someone in Hijackers’ Room Tells Housekeeper Not to Enter It, Although Hijackers Have Already Left
When a housekeeper at the Park Inn in Boston, where 9/11 hijackers Wail and Waleed Alshehri stayed before the attacks, attempts to clean their room, a “male of foreign descent” tells her she should not clean it yet and should return in the early afternoon, as someone is still asleep there. The hijackers are thought to have left the hotel and checked in for their flights several hours previously (see (6:20 a.m.-7:48 a.m.) September 11, 2001). The male’s identity is unknown and the housekeeper’s story appears to confuse the FBI, as an entry about it in an FBI timeline drafted after the attacks ends with five question marks. [Federal Bureau of Investigation, 10/2001, pp. 292
]
10:00 a.m. September 11, 2001: NEADS Notified of Suspected Hijacked Aircraft out of Canada
NORAD’s Northeast Air Defense Sector (NEADS) receives a call from a NORAD unit in Canada, reporting another suspected hijacked aircraft that is heading south from Canada, across the border toward Washington, DC. [Vanity Fair, 8/1/2006]
Aircraft Reported on Chat System – A member of staff at NEADS relays to their colleagues that the aircraft is from an “unknown departure airport, heading towards Washington,” but they do not “know any codes or anything” else about it. [North American Aerospace Defense Command, 9/11/2001] Another member of staff at NEADS calls the Canadian unit for more information. A Lance Corporal Nicholson there says only that he has seen “something on the chat” about a “possible” aircraft. [North American Aerospace Defense Command, 9/11/2001; North American Aerospace Defense Command, 9/11/2001] (Nicholson is presumably referring to NORAD’s computer chat system. [Spencer, 2008, pp. 139] )
Fighter Unit Contacted – According to author Lynn Spencer, NEADS battle commander Colonel Robert Marr contacts a military unit in Syracuse, New York, to get fighter jets sent after the suspicious flight. [Spencer, 2008, pp. 223] However, the first jets to launch from Syracuse will not take off until 10:42 a.m. (see 10:42 a.m. September 11, 2001). [Post-Standard (Syracuse), 9/12/2001]
Report Is a False Alarm – The suspected hijacking is soon revealed to be a false alarm. Nicholson will call from Canada and tell NEADS: “Be advised… that our [intelligence team] is not assessing that there is an actual aircraft problem. It’s just that there could be problems from our area.… There’s no actual aircraft that we suspect as being a danger.” He will add that his intelligence people “haven’t got any particular aircraft in mind.” [North American Aerospace Defense Command, 9/11/2001; Vanity Fair, 8/1/2006]
Numerous Erroneous Reports – This is one of the numerous mistaken reports of hijackings received during the course of the morning (see (9:09 a.m. and After) September 11, 2001). According to Vanity Fair: “In the barrage of information and misinformation, it becomes increasingly difficult for the controllers [at NEADS] to keep count of how many suspected hijackings are pending. So far, it is known that three have hit buildings, but given the uncertainty about the fates of American 11 and American 77—no one knows yet that this is the plane that hit the Pentagon—the sense at NEADS is that there are possibly three hijacked jets still out there, and who knows how many more yet to be reported.” At the time NEADS is informed of the suspicious aircraft coming in from Canada, “no one on the military side is aware that United 93 has been hijacked.” [Vanity Fair, 8/1/2006]
Shortly After 9:59 a.m. September 11, 2001: Navy Commander Tells New York City Deputy Mayor He Has Permission to Send Planes Over New York
Rudy Washington, who is one of Rudolph Giuliani’s deputy mayors, had earlier on called Admiral Robert Natter, the commander of the US Atlantic Fleet at Norfolk Naval Station, Virginia, and requested air cover over New York (see (Between 8:46 a.m. and 9:03 a.m.) September 11, 2001). After the WTC’s South Tower collapses at 9:59, Washington heads to City Hall, where he again communicates with Natter. Natter informs him that the Pentagon has been hit, and says he has now gotten permission from NORAD to send some fighter jets over the city. [New York Daily News, 5/20/2004] However, when exactly these jets are launched and when they arrive over New York is unstated. Patrick Burns, who is currently at the Norfolk Naval Station for his two-week Naval Reserve obligation, later recalls, “Air cover was already up with Navy jets out of Naval Air Station Oceana.” Naval Air Station Oceana, in Virginia Beach, Virginia, is home to F-14 Tomcat and F/A-18 Hornet fighters. But Burns does not state a time for when these fighters are airborne. [Virginian-Pilot, 9/22/2001; Digital Journalist, 10/2001; Notre Dame Magazine, 4/2007] The 9/11 Commission Report will make no mention of any Naval fighters. [9/11 Commission, 7/24/2004]
10:00 a.m. September 11, 2001: Flight 93’s Autopilot Turned Off; Alarms Sound
Based on information from the plane’s flight data recorder, the National Transportation Safety Board will later determine that Flight 93’s autopilot is turned off at “about 10:00,” and remains off for the flight’s final minutes. [National Transportation Safety Board, 2/13/2002
] Phil Bradshaw, whose wife is an attendant on Flight 93, will later hear the plane’s cockpit voice recording. Being a pilot himself, he recognizes on it the sound of the alarm that goes off when the autopilot is disconnected. [News and Record (Piedmont Triad, NC), 9/11/2002] CNN’s Kelli Arena will hear the recording during the 2006 Zacarias Moussaoui trial and will report that, shortly after this alarm sounds, “Another alarm goes off.” [CNN, 4/12/2006] According to journalist and author Jere Longman, as well as the alarm set off when the autopilot was disconnected, another alarm “would have sounded because the plane was traveling at five hundred seventy-five miles an hour in the final minutes, far exceeding the design limits of four hundred twenty-five miles an hour below twenty thousand feet and two hundred eighty-seven miles an hour below ten thousand feet.” [Longman, 2002, pp. 208] So presumably this is the second alarm described by Arena.
10:00 a.m. September 11, 2001: Palestinian Group Denies Responsibility for the Terrorist Attacks
The Democratic Front for the Liberation of Palestine (DFLP), a radical Palestinian group, denies responsibility for the terrorist attacks in the US after an Arab television station said it admitted responsibility for them. [Los Angeles Times, 9/12/2001; Poynter Institute, 9/2/2002] At around 9:43 a.m., Abu Dhabi television reported that it had received a call from the DFLP, claiming responsibility for crashing the planes into the World Trade Center (see (9:43 a.m.) September 11, 2001). [BBC, 9/12/2001] Now, however, a spokesman for the DFLP denies that the group was behind the attacks. [Poynter Institute, 9/2/2002] The spokesman who issues the denial at this time is apparently Qais Abdel Rahim, the leader of the DFLP. Speaking from the West Bank, Rahim says his group condemns the attacks. “We are not responsible for this type of terror attack. We are against it,” he says. [Associated Press, 9/11/2001; Liverpool Daily Post, 9/12/2001]
Group’s Leaders Are Unaware of the Attacks – DFLP officials will subsequently review the group’s worldwide operations to see if the group has any links to the attacks. “I called all the DFLP offices outside Palestine; I made sure they had no connection to the attacks—or even to the media reports,” Abu Laila, a senior figure in the DFLP, will later recall. The group’s leaders will tell him that “they were not even aware of the attacks.”
Official Statement Will Deny Responsibility for the Attacks – The DFLP will issue an official statement later today, denying responsibility for the attacks in the US. [Ma’an News Agency, 9/11/2011] “The Democratic Front rejects any kind of operation outside of the land of occupied Palestine, away from the immediate battlefield confronting the occupation forces and the armed settlers,” the statement will say. The DFLP will blame the false attribution of responsibility on “the Israeli security intelligence agencies,” which, it will state, “are trying to frame us.” These agencies, according to the statement, “orchestrated the set-up to criminalize our struggle because of our fidelity to this struggle, and our sophisticated way of organizing under the leadership of the working class and the progressive people of Palestine.” [Democratic Front for the Liberation of Palestine, 9/11/2001]
Experts Believe that Palestinian Groups Are Not to Blame – Most experts in the US will agree that “no Palestinian faction has the wherewithal to carry out such a coordinated and well-executed series of attacks” as have occurred today, according to the Los Angeles Times. [Los Angeles Times, 9/12/2001] One expert, Eli Carmon of the Herzliya Interdisciplinary Center’s counterterrorism department, will say it is unlikely that any Palestinian groups are involved. “They have a lot to lose because America would react very harshly against the Palestinians,” he will say. [Irish Examiner, 9/11/2001] “The DFLP does not even confront Israel; how would it confront the US?” Laila will comment. [Ma’an News Agency, 9/11/2011]
Shortly After 9:59 a.m. September 11, 2001: Police Officers Find WTC 7 Is Locked and on Fire
A group of police officers tries to enter World Trade Center Building 7 in order to get out of the WTC plaza, but they find the door is locked and the building is on fire. The seven officers are members of New York Police Department’s Emergency Service Unit (ESU). They were about 60 yards north of the South Tower when it collapsed, at 9:59 a.m. (see 9:59 a.m. September 11, 2001). When the dust began to clear, they made their way to the WTC plaza. But as they then tried to get out of the plaza, they found that every corner they ran to was blocked.
Officers Find the Door to WTC 7 Is Locked – The ESU officers now notice the bridge that leads from the plaza to WTC 7, and wonder if they can get out of the plaza by entering WTC 7 and then making their way down to the street below. [Tactical Edge, 6/2002
; Appel, 2009, pp. 99-100] WTC 7, a 47-story office building, is located to the north of the Twin Towers. It is linked to the main WTC complex by a glass-enclosed pedestrian bridge at the third-floor level. [Federal Emergency Management Agency, 5/1/2002, pp. 5-2; National Institute of Standards and Technology, 11/2008, pp. 2] The officers walk across the bridge, but when they reach the door that leads into WTC 7 they find it is locked. “Why anyone would lock a door under these circumstances was anybody’s guess,” author Anthea Appel will later comment.
Officers Find WTC 7 Is on Fire – One officer, Steve Lanoce, decides to try to break the door. He takes out his handgun and fires a shot at the bottom glass pane of the door. The glass, however, turns out to be bullet-proof and cracks but does not break. Furthermore, Lanoce’s shot sets off the burglar alarm in WTC 7. Fortunately, Lanoce’s colleagues are able to kick in the cracked glass and create an opening large enough to crawl through. They find, though, that the building on the other side of the door is on fire and they have to jump back to avoid the flames. [Tactical Edge, 6/2002
; Appel, 2009, pp. 99-100]
WTC 7 Suffered Only Minor Damage When the South Tower Collapsed – The cause of the fire in WTC 7 is unclear. The National Institute of Standards and Technology, which will investigate the collapse of WTC 7 that occurs later today (see (5:20 p.m.) September 11, 2001), will state that the building suffered only minor damage when the South Tower collapsed. “A few windows on lower floors of the south face of WTC 7 were broken, and dust and small debris were deposited in the third-floor lobby,” it will describe. However, it will add, “None of the large pieces of debris from [the South Tower] hit WTC 7 because of the large distance between the two buildings and there was no evidence of structural damage to WTC 7.” [National Institute of Standards and Technology, 11/2008, pp. 16] The ESU officers then notice a stream of people making their way out of the North Tower. They therefore abandon their plan to get out of the WTC complex and instead go to help evacuate the civilians from the tower. [Tactical Edge, 6/2002
; Appel, 2009, pp. 101]
