Here is what happened on the fateful morning of September 11, 2001 and how the attacks unfolded:
WHAT HAPPENED ON 9/11
Different teams of hijackers (terrorists associated with al-Qaida) crashed four American airliners on the way to California from the northeast. Five hijackers crashed the first plane – American Airlines Flight 11 – into the World Trade Centre’s North Tower at 8:46am in Lower Manhattan. Soon after, the South Tower was hit by hijacked United Airlines Flight 175. Passengers on board both the planes were killed, along with those present in the towers and surrounding areas. A third plane ‘American Airlines Flight 77’, hijacked by five other terrorists, destroyed the west wall of the Pentagon. The fourth and the final flight ‘United Airlines Flight 93’ crashed in Pennsylvania after the heroic passengers fought with the four hijackers.

United Airlines Flight 93 (Boeing 757-222) left Newark International Airport for San Francisco with 33 passengers, a crew of seven and four hijackers at 8:42am. One of the passengers used his cell phone to dial 911 after closing himself in a restroom to avoid detection. The flight was flying so low around 9:58am that he succeeded in reaching an emergency operator in nearby Westmoreland County, Pennsylvania. At 10.03am, the hijackers were forced to crash Flight 93 in a field in Somerset County, Pennsylvania, after brave passengers and crew members fought back and stormed the cockpit.

Nineteen terrorists linked to al-Qaida, founded by Osama bin Laden, carried out the coordinated attacks by hijacking the four commercial airliners on September 11, 2001. While 15 of the 19 terrorists were from Saudi Arabia, two belonged to the United Arab Emirates and one each were from Lebanon and Egypt.

Khalid Sheikh Mohammed, known as the ‘mastermind’ behind the 9/11 attacks on the US, was arrested on March 1, 2003 in Rawalpindi by Pakistani security officials working with the CIA. Currently in a cell in a high-security camp on the US naval base at Guantanamo Bay in Cuba, Mohammed was subjected to waterboarding 183 times, sleep deprivation and other harsh techniques. In September 2006, he confessed his responsibility for the attacks. “I was responsible for the 9/11 operation, from A to Z,” he had said. He is yet to be tried and convicted for the heinous crime.
