Hijacking refers to the unlawful seizure of a vehicle, aircraft, or other modes of transportation, typically by force or threat. This act can involve taking control of a plane, bus, or ship, often with the intent to demand ransom, make political statements, or achieve other objectives. In the context of aviation, hijacking gained significant attention during the late 20th century, leading to increased security measures at airports worldwide. Governments and organizations have since implemented various strategies to prevent such incidents, including enhanced screening processes and international cooperation among law enforcement agencies.
