Investigators say they have found debris from the Flight 93 crash far from the main crash site. A second debris field centers around Indian Lake about three miles from the crash scene, where eyewitnesses report seeing falling debris only moments after the crash. More debris is found in New Baltimore, some eight miles away. Later in the day, the investigators say all that debris likely was blown there. [CNN, 9/13/2001; Pittsburgh Post-Gazette, 9/13/2001] Another debris field is found six miles away, and human remains are found miles away. State police and the FBI have cordoned off an area where there is plane debris, about six to eight miles from the main crash site. After all of this is discovered, the FBI still “stresses” that “no evidence [has] surfaced” to support the idea that the plane was shot down. [CNN, 9/13/2001; Pittsburgh Post-Gazette, 9/13/2001] A half-ton piece of one of the engines is found 2,000 yards away from the main crash site. This was the single heaviest piece recovered from the crash. [Philadelphia Daily News, 12/28/2001; Independent, 8/13/2002] Days later, the FBI says the wide debris field was probably the result of the explosion on impact. The Independent nevertheless later cites the wide debris field as one of many reasons why widespread rumors remain that the plane was shot down. [Independent, 9/20/2001]
September 13-14, 2001: Men Arrested at New York Airports, but Soon Released after No Connections Found to 9/11 Attacks
On September 13, New York authorities take into custody ten people of Middle Eastern descent at JFK International and La Guardia Airports, reportedly fearing they intend to hijack aircraft and commit another suicidal terrorist attack on a US target. This leads to all three major New York-area airports—JFK, La Guardia, and Newark—being abruptly shut down, just hours after they reopened for the first time since the 9/11 attacks took place. [Associated Press, 9/14/2001; Dallas Morning News, 9/14/2001; New York Times, 9/14/2001; Washington Post, 9/14/2001]
Armed and Carrying False ID – According to the Washington Post, the detained individuals are carrying knives and false identification. [Washington Post, 9/14/2001] Four of them are reportedly arrested as they try to board a flight from JFK Airport to Los Angeles, and a woman is held on suspicion of assisting these four. Some of the four are reported as having pilots’ certificates from Flight Safety International in Vero Beach, Florida, where some of the alleged 9/11 hijackers are currently believed to have taken flying lessons. Later on, the other five men are arrested at La Guardia Airport “under similar circumstances.” [Dallas Morning News, 9/14/2001] According to the New York Times, “Law enforcement officials said one of those held was carrying a false pilot’s identification.” Furthermore, several of the detained men “showed up at the airport with tickets for flights canceled on Tuesday [September 11] and tried to use them.” Investigators say they believe one of the men had been among a group of passengers that behaved suspiciously and became aggressive after their aircraft—United Airlines Flight 23—had its takeoff canceled on the morning of 9/11 (see (After 9:19 a.m.) September 11, 2001). New York Police Commissioner Bernard Kerik says one of the men arrested at JFK Airport “attempted to clear security and he was stopped.” [New York Times, 9/14/2001]
Men Released, No Connections Found to 9/11 Attacks – However, the following morning the FBI announces that none of the detainees had any connection to the 9/11 attacks, and all but one of them have been released. Barry Mawn, the head of the New York FBI office, says: “The reporting that has been going on all night, I can definitively tell you, is inaccurate.… [W]e did talk to approximately a dozen individuals. We have only one individual left who is still being questioned by the task force. All other ten have been released.” [CNN, 9/14/2001; PBS, 9/14/2001] Justice Department spokeswoman Mindy Tucker says that no knives, box cutters, guns, or other weapons were found on the individuals. [Washington Post, 9/15/2001] After talking to the directors of the FBI and CIA, Senator Joseph Biden (D-DE) tells CNN that the detained men had “no connection whatsoever to what happened at the World Trade towers or the Pentagon, or this organizational network.” He explains: “One guy, an actual pilot, got on the plane, coincidentally had his brother’s identification as well. His brother happened to live in the apartment complex that was one in Boston where some of [the alleged hijackers] had actually been.” Biden adds: “Ten other people were going to a Boeing conference. They had stickers on their bags.… The folks at the airport thought, hey, wait a minute, are they impersonating crew? And they weren’t.” Biden says the one man who has not yet been released “was a screwball who was acting out, you know, acting out and saying and demanding.… Making problems, and they arrested him.” By 11:20 a.m. on September 14, the three New York-area airports are reopened. [Associated Press, 9/14/2001; CNN, 9/14/2001]
September 13-14, 2001: Flight 93 Black Boxes Found
Around 4:50 p.m. on September 13, investigators discover the flight data recorder from Flight 93, one of the plane’s two “black boxes.” It is buried about 15 feet down in the main crater at the crash site, near Shanksville, Pennsylvania. Around 8:25 p.m. the following evening, the other ‘black box’—the plane’s cockpit voice recorder—is found about 25 feet below ground in roughly the same spot. [Pittsburgh Post-Gazette, 9/13/2001; Pittsburgh Post-Gazette, 9/15/2001; Longman, 2002, pp. 217] The flight data recorder monitors airplane functions like its speed and altitude, while the cockpit voice recorder picks up conversations in the plane’s cockpit. [Pittsburgh Post-Gazette, 9/14/2001] Both are mounted in a plane’s tail. They are encased in very strong materials, like titanium, and insulated so as to withstand a crash impact. [BBC, 9/15/2001] Wells Morrison, the FBI’s second in command at the Flight 93 crash scene, later comments, “It was strange. The black boxes are right next to each other on the aircraft, but one was found thirteen feet deeper into the crater than the other.… We were surprised, quite honestly, that we didn’t find them sooner.” [Kashurba, 2002, pp. 109 and 115] The cockpit voice recorder is sent to the National Transportation Safety Board (NTSB) in Washington, and then on to its manufacturer, Honeywell, to try to extract information from it. [CBS News, 9/16/2001; Pittsburgh Post-Gazette, 11/4/2001] It is supposedly the only one from the four hijacked flights to have survived the crash impact and ensuing fire. [9/11 Commission, 7/24/2004, pp. 456] In April 2002, the 31-minute recording from it is played in private to victims’ relatives (see April 18, 2002). It will be played in public for the first time in April 2006, during the trial of Zacarias Moussaoui (see April 12, 2006). [CNN, 4/13/2006]
September 13, 2001: Sudden Fire in Crash Area Disrupts Recovery Operations at Pentagon
Late in the evening of September 13, 2001, search and rescue operations at the Pentagon have to be temporarily suspended when—after firefighters thought they had the crash site under control—a sizeable fire breaks out, sending smoke hundreds of feet into the air. [CNN, 9/13/2001; Associated Press, 9/14/2001; CNN, 9/14/2001; NPR, 9/14/2001] The fire erupts in the pile of debris at the impact area where the aircraft hit the Pentagon, and is apparently caused by a “hot spot” that reignited. Fire commanders had been concerned about the smoke coming from the pile earlier in the evening, yet there is no engine available to extinguish any fire. There was an engine by the pile all through the day, but this left at the end of the day shift. Because of tightened security, the engine due to replace it is taking longer than usual to arrive. [Creed and Newman, 2008, pp. 389 and 393] The order goes out: “We need everybody to evacuate. The building is on fire again.” Firefighters and workers for agencies such as the FBI and FEMA evacuate, either to the lawn in front of the crash site or the Pentagon’s center courtyard. Yet the fire appears to be contained in the rubble pile, with little danger of spreading. One worker questions: “So why are they stopping us? Why can’t we keep working?” [Creed and Newman, 2008, pp. 393-394 and 400-401] Eventually, a fire truck arrives to tackle the blaze. About two hours after it first flared up, the fire is out and recovery workers can continue their activities. [CNN, 9/14/2001; Creed and Newman, 2008, pp. 394-395 and 401] Firefighting and other rescue operations were also significantly disrupted three times during September 11-12, due to false alarms over unidentified aircraft approaching Washington (see (10:15 a.m.-10:38 a.m.) September 11, 2001, (2:00 p.m.) September 11, 2001, and (10:00 a.m.) September 12, 2001). [Fire Engineering, 11/2002]
September 13, 2001-Mid 2002: 9/11 Hijackers’ Associate Cooperates with FBI
Mohamed el-Atriss, who supplied some of the hijackers with fake IDs (see (July-August 2001)), is visited by FBI agents and begins to help them with their inquiries. [Washington Post, 2/5/2003; Newark Star-Ledger, 10/20/2003] El-Atriss turns over his files to the FBI and, according to his lawyer, promises to “keep his eyes and ears open” for other Islamic militants. He tells the FBI he did not know the hijackers’ intentions when he sold them the ID cards. [Bergen Record, 9/11/2006] He is interviewed extensively by federal authorities over the next few months and successfully passes a lie detector test confirming he did not know they intended to hijack a plane. [Newark Star-Ledger, 10/20/2003] However, authorities plant an electronic surveillance device inside a printer he orders, to monitor who he is making documents for. [Bergen Record, 9/11/2006] El-Atriss’ usefulness suffers a setback when a local sheriff raids his business and arrests him in 2002 (see July 31, 2002), apparently without the FBI’s approval (see July 31, 2002 and After).
September 13, 2001-September 14, 2001: 18 Hijackers Named, Mysterious Name and Then Hanjour’s Name Follows One Day Later
On September 13, the FBI says there were 18 hijackers, and releases their names. Hani Hanjour’s name is not on the list. [CNN, 9/13/2001] On the morning of the next day, CNN announces on the air that “CNN managed to grab a list of the names of the 18 suspected hijackers that is supposed to be officially released by justice sometime later today.” An announcer reads the list, which actually contains 19 names. It is the same list as the day before, except for one new name: Mosear Caned. (Note that the name is a very rough phonetic spelling from a CNN transcript.) [CNN, 9/14/2001] Later in the day, the list is revised. Caned is gone and is replaced by Hani Hanjour. It is never explained who Caned is, how he got on the list, or even how his name is correctly spelled. No name even remotely similar to his appears on any of the released manifests of the hijacked 9/11 flights. [CNN, 9/14/2001; Associated Press, 9/14/2001] A few days later, it is reported that Hanjour’s “name was not on the American Airlines manifest for [Flight 77] because he may not have had a ticket.” [Washington Post, 9/16/2001]
September 13-27, 2001: ‘Hot Spots’ Found in the Ground at Flight 93 Crash Scene
At the Flight 93 crash site, an excavator digs through the soil where the plane impacted. [St. Anthony Messenger, 9/6/2006] It takes scoops of dirt and dumps them into a high-lift bucket, which takes the dirt to a flagged off area and slowly dumps it there. A couple of FBI men then search through it with their hands. Occasionally, the excavator digs into a “hot spot” in the earth, causing a small fire. The Shanksville Volunteer Fire Department has to be called in to extinguish these fires. [Kashurba, 2002, pp. 56 and 128] The cause of the ‘hot spots’ is unknown.
September 12, 2001 and Shortly After: 9/11 Hijackers’ Effects Found at Flight 93 Crash Site
Several effects apparently belonging to Flight 93 hijackers are recovered from the crash site in Somerset County. They are: 
A Saudi Arabian ID card of Ahmed Alnami; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] A Saudi Arabian Youth Hostel Association card of Ahmed Alnami; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Two passport sized photographs of Ahmed Alnami; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] A charred section of Ziad Jarrah’s passport; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Saeed Alghamdi’s Saudi Arabian passport; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] A business card of Assem Jarrah, Ziad Jarrah’s second cousin (who allegedly has been a spy for three governments (see September 16, 2002)). It has Ramzi bin al-Shibh’s Hamburg address written on the back (see September 24, 2002); [US District Court for the Eastern District of Virginia, Alexandria Division, 3/7/2006; US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] Part of Ahmed Alnami’s Florida driving license; [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006] A red bandana (a passenger on Flight 93 described the hijackers as using red bandanas, though this could have been someone else’s bandana (see (9:37 a.m.) September 11, 2001). [US District Court for the Eastern District of Virginia, Alexandria Division, 7/31/2006]
September 14, 2001: Officials Deny Flight 93 Shot Down
Officials deny that Flight 93 was shot down, but propose the theory that the hijackers had a bomb on board and blew up the plane. [Pittsburgh Tribune-Review, 9/14/2001] Later in the month, it is reported that the “FBI has determined from the on site investigation that no explosive was involved.” [Associated Press, 9/25/2001]
September 14, 2001: Investigators Find Flight 77 Black Boxes, but Accounts Conflict over Details
At around 3:40 a.m., investigators at the Pentagon recover the two “black boxes” from Flight 77. [Washington Times, 9/14/2001] These boxes are the plane’s flight data recorder and its cockpit voice recorder. [BBC, 9/15/2001] Some news reports claim they are found by two Fairfax County firefighters, Carlton Burkhammer and Brian Moravitz, as they comb through debris near the impact site. [Washington Post, 9/19/2001; Newsweek, 9/28/2001] But according to Arlington County spokesman Dick Bridges, members of the FBI’s evidence response team find them. [PBS, 9/14/2001; Washington Post, 9/14/2001] Authors Patrick Creed and Rick Newman will later clarify that Burkhammer and Moravitz find an object initially believed to be one of the black boxes, but closer inspection reveals it to be just “a charred chunk of machinery.” Subsequently, FBI photographer Jennifer Hill finds the cockpit voice recorder in a stack of rubble while assisting searchers. Thirty minutes later, a National Transportation Safety Board (NTSB) expert locates the flight data recorder in the same area. [Creed and Newman, 2008, pp. 396-397 and 400-402] But Allyn Kilsheimer, a structural engineer who helps coordinate the emergency response at the Pentagon, later claims he had “found the black box,” which, he says, he had “stepped on… by accident.” [GW Magazine, 3/2002; Popular Mechanics, 3/2005] Washington FBI agent Christopher Combs says, “Somebody almost threw [the black boxes] away because they didn’t know what they looked like.” [Disaster News Network, 10/30/2002]
Conflicting Accounts of Where Boxes Are Found – According to Dick Bridges, the two recorders are discovered “right where the plane came into the building.” [Associated Press, 9/14/2001] But the American Society of Civil Engineers’ Pentagon Building Performance Report, released in 2003, will claim that the flight data recorder was found “nearly 300 ft into the structure.” [Mlakar et al., 1/2003, pp. 40 
] In Creed and Newman’s account, the recorders are found in the Pentagon’s middle C Ring, near the “punch-out” hole made by the impacting aircraft. [Creed and Newman, 2008, pp. 400-402]
Boxes Taken Away for Analysis – The boxes are taken to the NTSB’s laboratory in Washington, where data is extracted from the flight data recorder, but they are reclaimed by the FBI later on in the morning. [Washington Times, 9/14/2001; Creed and Newman, 2008, pp. 402] A flight data recorder tracks an airplane’s flight movements for the last 25 hours, while the cockpit voice recorder contains radio transmissions and sounds from the cockpit for the last 30 minutes of its flight. Both are mounted in the tail of an aircraft and are encased in very strong materials like titanium. According to American Airlines and United Airlines, the black boxes aboard Flight 77 and the other hijacked planes were modern solid-state versions, which are more resistant to damage than older magnetic tape recorders. [Associated Press, 9/15/2001; BBC, 9/15/2001] FBI Director Robert Mueller later says that Flight 77’s data recorder has provided altitude, speed, and other information about the flight, but the voice recorder contained “nothing useful.” [CBS News, 2/25/2002] The 9/11 Commission will describe the cockpit voice recorder as being “badly burned and not recoverable.” [9/11 Commission, 7/24/2004, pp. 456] According to CBS News, preliminary information shows that the cockpit voice tape “appears to be blank or erased.” [CBS News, 9/16/2001] The two black boxes from Flight 93 are also recovered around this time (see September 13-14, 2001).
