Flight 93 was a domestic passenger flight that was hijacked on September 11, 2001, as part of a coordinated terrorist attack by al-Qaeda. The passengers aboard the flight heroically attempted to regain control from the hijackers, ultimately leading to the plane crashing into a field in Pennsylvania instead of its intended target, believed to be either the U.S. Capitol or the White House. This event became a symbol of resistance and bravery during one of the darkest days in American history.
