American Airlines Flight 11 was a scheduled U.S. domestic passenger flight from Logan International Airport in Boston, Massachusetts, to Los Angeles International Airport. It was hijacked by five Islamic terrorists and deliberately crashed into the North Tower of the World Trade Center in New York City as part of the September 11, 2001, attacks. Fifteen minutes into the flight, the hijackers injured at least three people, forcefully breached the cockpit, and overpowered the pilot and first officer. Mohamed Atta, who was a known member of al-Qaeda, and trained as a pilot, took over the controls. Air traffic controllers noticed the flight was in distress when the crew stopped responding to them. They realized the flight had been hijacked when Atta mistakenly transmitted announcements for passengers to air traffic control. On board, two flight attendants contacted American Airlines, and provided information about the hijackers and injuries to passengers and crew. The aircraft crashed into the North Tower of the World Trade Center at 08:46 local time; the impact killed all 92 people aboard, including the hijackers.
