On September 11, 2001, 19 militants associated with the Islamic extremist group al-Qaeda hijacked four airliners and carried out suicide attacks against targets in the United States. Two of the planes were flown into the towers of the World Trade Center in New York City, a third plane hit the Pentagon just outside Washington, D.C., and the fourth plane crashed in a field in Pennsylvania. Often referred to as 9/11, the attacks resulted in extensive death and destruction, triggering major U.S. initiatives to combat terrorism and defining the presidency of George W. Bush. Over 3,000 people were killed during the attacks in New York City and Washington, D.C., including more than 400 police officers and firefighters.
As millions watched the events unfolding in New York, American Airlines Flight 77 circled over downtown Washington, D.C., and slammed into the west side of thePentagon military headquarters at 9:45 a.m. Jet fuel from the Boeing 757 caused a devastating inferno that led to the structural collapse of a portion of the giant concrete building. All told, 125 military personnel and civilians were killed in the Pentagon, along with all 64 people aboard the airliner.
Less than 15 minutes after the terrorists struck the nerve center of the U.S. military, the horror in New York took a catastrophic turn for the worse when the south tower of the World Trade Center collapsed in a massive cloud of dust and smoke. The structural steel of the skyscraper, built to withstand winds in excess of 200 miles per hour and a large conventional fire, could not withstand the tremendous heat generated by the burning jet fuel. At 10:30 a.m., the other Trade Center tower collapsed. Close to 3,000 people died in the World Trade Center and its vicinity, including a staggering 343 firefighters and paramedics, 23 New York City police officers and 37 Port Authority police officers who were struggling to complete an evacuation of the buildings and save the office workers trapped on higher floors. Only six people in the World Trade Center towers at the time of their collapse survived. Almost 10,000 others were treated for injuries, many severe.
Meanwhile, a fourth California-bound plane–United Flight 93–was hijacked about 40 minutes after leaving Newark International Airport in New Jersey. Because the plane had been delayed in taking off, passengers on board learned of events in New York and Washington via cell phone and Airfone calls to the ground. Knowing that the aircraft was not returning to an airport as the hijackers claimed, a group of passengers and flight attendants planned an insurrection. One of the passengers, Thomas Burnett Jr., told his wife over the phone that “I know we’re all going to die. There’s three of us who are going to do something about it. I love you, honey.” Another passenger–Todd Beamer–was heard saying “Are you guys ready? Let’s roll” over an open line. Sandy Bradshaw, a flight attendant, called her husband and explained that she had slipped into a galley and was filling pitchers with boiling water. Her last words to him were “Everyone’s running to first class. I’ve got to go. Bye.”
The passengers fought the four hijackers and are suspected to have attacked the cockpit with a fire extinguisher. The plane then flipped over and sped toward the ground at upwards of 500 miles per hour, crashing in a rural field in westernPennsylvania at 10:10 a.m. All 45 people aboard were killed. Its intended target is not known, but theories include the White House, the U.S. Capitol, the Camp David presidential retreat in Maryland or one of several nuclear power plants along the eastern seaboard.
At 7 p.m., President George W. Bush, who had spent the day being shuttled around the country because of security concerns, returned to the White House. At 9 p.m., he delivered a televised address from the Oval Office, declaring, “Terrorist attacks can shake the foundations of our biggest buildings, but they cannot touch the foundation of America. These acts shatter steel, but they cannot dent the steel of American resolve.” In a reference to the eventual U.S. military response he declared, “We will make no distinction between the terrorists who committed these acts and those who harbor them.”
Operation Enduring Freedom, the American-led international effort to oust the Taliban regime in Afghanistan and destroy Osama bin Laden’s terrorist network based there, began on October 7. Within two months, U.S. forces had effectively removed the Taliban from operational power, but the war continued, as U.S. and coalition forces attempted to defeat a Taliban insurgency campaign based in neighboring Pakistan. Osama bin Laden, the mastermind behind the September 11th attacks, remained at large until May 2, 2011, when he was finally tracked down and killed by U.S. forces at a hideout in Abbottabad, Pakistan. In June 2011, President Barack Obama announced the beginning of large-scale troop withdrawals from Afghanistan, with a final withdrawal of U.S. forces tentatively scheduled for 2014.
