What happened
On the morning of September 11, 2001, a Boeing 767 departed from Boston-Logan International Airport at 07:59 local time. The aircraft was operating a scheduled commercial flight bound for Los Angeles, carrying a total of 81 passengers and 11 crew members.
Shortly after takeoff, the aircraft was taken over by terrorists who altered the intended flight path. The plane was redirected toward New York City. At 08:45 local time, the aircraft impacted the North Tower of the World Trade Center complex, striking the structure between the 94th and 99th floors. The force of the collision caused the aircraft to disintegrate. The subsequent damage to the tower eventually led to its collapse.
Findings
All 92 occupants on the aircraft perished during the event. The incident was part of a coordinated terrorist attack. Due to the nature of the investigation, which falls under the jurisdiction of the Federal Bureau of Investigation, the National Transportation Safety Board provided technical support but did not release a formal safety report or public docket.
