United States invasion of Afghanistan
On the morning of 11 September 2001, al-Qaeda carried out four coordinated attacks on the United States. Four commercial passenger jet airliners were hijacked. The hijackers – members of al-Qaeda's Hamburg cell – intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City. Both buildings collapsed within two hours from fire damage related to the crashes, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon in Arlington County, Virginia. The fourth plane crashed into a field near Shanksville, Pennsylvania, after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington, D.C., to target the White House or the United States Capitol. No flights had survivors. In total, 2,996 people, including the 19 hijackers, died and more than 6,000 others injured in the attacks. According to the New York State Health Department, 836 first responders, including firefighters and police personnel, had died as of June 2009.
Ziad Jarrah
On the morning of September 11, 2001, Jarrah, Saeed al-Ghamdi, Ahmed al-Nami and Ahmed al-Haznawi boarded United Airlines Flight 93 from Newark International Airport at gate A17 without incident, and sat in first-class seats near the cockpit. Before boarding, Ziad Jarrah called his girlfriend, Aysel Sengün, from a public telephone at the airport, repeating the words 'I love you' over and over. Due to the flight's delay, the plane took off at 8:41 am, five minutes before American Airlines Flight 11 crashed into the World Trade Center. The pilot and crew were notified of the first two hijackings that day, and were told to be on the alert. Within minutes, around 9:28 am, Flight 93 was hijacked as well. The 9/11 Commission stated that Jarrah was the pilot.
