American Airlines Flight 11

American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda members on September 11 in 2001, as part of the September 11 attacks. Mohamed Atta deliberately crashed the plane into the North Tower of the World Trade Center in New York City, killing all 92 people aboard and an unknown number in the building's impact zone. The aircraft involved, a Boeing 767-223ER, registration N334AA, was flying American Airlines' daily scheduled morning transcontinental service from Logan International Airport in Boston to Los Angeles International Airport in Los Angeles.

Fifteen minutes into the flight, the hijackers injured at least three people , forcibly breached the cockpit, and overpowered the captain and first officer. Atta, an al-Qaeda member and licensed commercial pilot, took over the controls. Air traffic controllers noticed the flight was in distress when the crew was no longer responding. They realized the flight had been hijacked when Mohamed Atta's announcements for passengers were transmitted to air traffic control. On board, flight attendants Amy Sweeney and Betty Ong contacted American Airlines, and provided information about the hijackers and injuries to passengers and crew.
