AA11

American Airlines Flight 11, designated as AA11, was a scheduled transcontinental passenger flight operated by American Airlines from Boston Logan International Airport (BOS) to Los Angeles International Airport (LAX). It was flown on a Boeing 767-223ER with registration N334AA. On September 11, 2001, the aircraft was hijacked shortly after takeoff by five al-Qaeda militants and was flown into the North Tower of the World Trade Center in New York City at 8:46 a.m. Eastern Time, becoming the first of the 9/11 attacks to crash into a building.

All 92 people aboard were killed, including 81 passengers and 11 crew. The impact and ensuing fires caused extensive damage to the North Tower, which subsequently collapsed as part of the day’s attacks. The crash occurred during a coordinated assault that also involved another hijacked airliner later that morning.

The flight originated at BOS and was scheduled to continue to LAX. The events of AA11, together with the other attacks, had far-reaching consequences for global security and aviation. In the wake of the attacks, authorities implemented widespread changes in airport security, airspace management, and counterterrorism policy, contributing to the creation of new agencies and the reinforcement of cockpit doors, screening protocols, and emergency-response procedures. AA11 remains a central reference point in histories of the September 11 attacks and their enduring impact on security practices and international relations.
