102 minutes that changed the world (9/11) Part 3


Early in the morning on September 11, 2001, nineteen hijackers took control of four commercial airliners en route to San Francisco and Los Angeles from Boston, Newark, and Washington, D.C. (Washington Dulles International Airport).[1] At 8:46 a.m., American Airlines Flight 11 was crashed into the World Trade Centers North Tower, followed by United Airlines Flight 175 which hit the South Tower at 9:03 a.m.[7][8] Another group of hijackers flew American Airlines Flight 77 into the Pentagon at 9:37 a.m.[9] A fourth flight, United Airlines Flight 93, whose ultimate target was thought to be either the United States Capitol or White House, crashed near Shanksville, Pennsylvania at 10:03 a.m.[10][11]
During the hijacking of the airplanes, the hijackers used weapons to stab and/or kill aircraft pilots, flight attendants and passengers. Reports from phone callers from the planes indicated that knives were used by the hijackers to stab attendants and in at least one case, a passenger, during two of the hijackings.[12][13] Some passengers were able to make phone calls using the cabin airphone service and mobile phones,[14][15] and provide details, including that several hijackers were aboard each plane, that mace or other form of noxious chemical spray, such as tear gas or pepper spray was used, and that some people aboard had been stabbed.[16][17][18][19] The 9/11 Commission established that two of the hijackers had recently purchased Leatherman multi-function hand tools.[20] A flight attendant on Flight 11, a passenger on Flight 175, and passengers on Flight 93 mentioned that the hijackers had bombs, but one of the passengers also mentioned he thought the bombs were fake. No traces of explosives were found at the crash sites, and the 9/11 Commission believed the bombs were probably fake.[12]
On United Airlines Flight 93, black box recordings revealed that crew and passengers attempted to seize control of the plane from the hijackers after learning through phone calls that similarly hijacked planes had been crashed into buildings that morning.[21] According to the transcript of Flight 93s recorder, one of the hijackers gave the order to roll the plane once it became evident that they would lose control of the plane to the passengers.[22] Soon afterward, the aircraft crashed into a field near Shanksville in Stonycreek Township, Somerset County, Pennsylvania, at 10:03:11 a.m. local time (14:03:11 UTC). Khalid Sheikh Mohammed, organiser of the attacks, mentioned in a 2002 interview with Yosri Fouda, an al Jazeera journalist, that Flight 93s target was the United States Capitol, which was given the code name "the Faculty of Law".[23]
Three buildings in the World Trade Center Complex collapsed due to structural failure on the day of the attack.[24] The south tower (2 WTC) fell at approximately 9:59 a.m., after burning for 56 minutes in a fire caused by the impact of United Airlines Flight 175.[24] The north tower (1 WTC) collapsed at 10:28 a.m., after burning for approximately 102 minutes.[24] When the north tower collapsed, debris heavily damaged the nearby 7 World Trade Center (7 WTC) building. Its structural integrity was further compromised by fires, and the building collapsed later in the day at 5:20 p.m.[25]
The attacks created widespread confusion among news organizations and air traffic controllers across the United States. All international civilian air traffic was banned from landing on US soil for three days.[26] Aircraft already in flight were either turned back or redirected to airports in Canada or Mexico. News sources aired unconfirmed and often contradictory reports throughout the day. One of the most prevalent of these reported that a car bomb had been detonated at the U.S. State Departments headquarters in Washington, D.C.[27] Soon after reporting for the first time on the Pentagon crash, CNN and other media also briefly reported that a fire had broken out on the Washington Mall.[28] Another report went out on the AP wire, claiming that a Delta Air Lines airliner—Flight 1989—had been hijacked. This report, too, turned out to be in error; the plane was briefly thought to represent a hijack risk, but it responded to controllers and landed safely in Cleveland, Ohio
