Twin Towers Fall: 9/11 Shatters American Security

Nearly three thousand people perished in under two hours on a clear September morning, victims of the deadliest terrorist attack ever carried out on American soil. Four commercial airliners, hijacked by nineteen al-Qaeda operatives, became weapons aimed at the symbols of U.S. economic and military power. The coordinated assault shattered assumptions about homeland security that had stood unchallenged since Pearl Harbor. American Airlines Flight 11 struck the North Tower of the World Trade Center at 8:46 a.m. Seventeen minutes later, United Airlines Flight 175 slammed into the South Tower as television cameras broadcast the horror worldwide. American Airlines Flight 77 hit the western face of the Pentagon at 9:37 a.m., and United Flight 93, its passengers having learned of the other crashes by phone, was driven into a field near Shanksville, Pennsylvania, after they stormed the cockpit to prevent its intended target in Washington. Both towers collapsed within 102 minutes of impact, burying thousands of office workers, first responders, and bystanders beneath a mountain of steel and pulverized concrete. The New York City Fire Department lost 343 firefighters, the single greatest loss of emergency personnel in American history. At the Pentagon, 125 military and civilian employees died alongside the 64 people aboard Flight 77. The attacks triggered a wholesale transformation of American foreign and domestic policy. Within weeks, Congress authorized military force in Afghanistan to dismantle al-Qaeda and topple the Taliban regime that harbored its leadership. The USA PATRIOT Act expanded surveillance powers, the Department of Homeland Security consolidated 22 federal agencies, and airport security shifted to the newly created Transportation Security Administration. The reverberations shaped two decades of warfare, reshaped civil liberties debates, and left a wound in the national consciousness that remains raw more than twenty years later.
